Multi-Sca le Approach Elucidating the Physics of Environmental Resilience" presente d by Manolis Veveakis\, PhD Associate Professor Civil and Environmental E ngineering Duke University \nAbstract: \nEnvironmental Resilience is the ability of geomaterials to maintain an acceptable level of strength for e ngineering applications (whether structural\, hydrogeological or geotechn ical) while exposed in long-term natural environmental adversity. In this talk we will show that the environmental resilience of rocks is a proper ty that depends on both the compositional and morphological properties of materials\, but also on the environmental factors that can affect and al ter them at different degrees and scales. We show that starting from digi tized CT-scan images of rocks and combining experimental\, numerical and theoretical concepts we develop a three-scale modeling approach (km -or e ngineering- scale\, cm scale and sub-mm scale) whereby the resilience of rocks in the engineering scale is directly linked to their microstructura l response in a variety of loading scenarios. Using metaheuristic approac hes a predictive constitutive relationship linking the response of rocks with their morphometric properties (porosity\, surface area\, grain size and Euler characteristic) and environmental factors (temperature\, pressu re\, chemistry of saturating fluids) is retrieved and tested. Finally\, e xamples of coupled mechanical deformation at elevated temperatures and/or in the presence of chemically active fluids that alter the microstructur e of the digital rock samples and affect the macroscopic response of rock s at the engineering scale will be discussed.\n\nFaculty\, Graduate Stude nts & Postdocs Welcome!\nThis is an in-person-only event.\nFirst 10 stude nts to sign-up upon arrival are invited to a free post-event dinner with the speaker at Broadhead Center.

Typical movement p atterns are often considered optimal in certain ways\, such as for minimu m energy consumption or favorable stability\; yet these patterns differ a cross individuals and can be altered by age\, injury\, or behavior. This presentation will interweave several areas of ongoing research in locomot ion biomechanics and motor control\, such as: why and how upper body move ment can affect the ankles\; wearable technology and methods to measure a nd alter biomechanics in the "real world"\; biomechatronic prosthetic ank les to improve stability and balance\; and novel rehabilitation robots to study and train motor control in the legs. \nBrief Bio:\nDr. Peter Adam czyk earned degrees in Mechanical Engineering from Case Western Reserve U niversity (B.S.) and the University of Michigan (M.S. and Ph.D) in the ar eas of Robotics and Biomechanics. He spent several years running a startu p company dedicated to advancing the science and technology of lower-limb prosthetics and real-world motion assessment. He is now the Mead Witter Foundation Associate Professor in Mechanical Engineering at the Universit y of Wisconsin-Madison where he directs the Biomechatronics\, Assistive D evices\, Gait Engineering and Rehabilitation Laboratory (UW BADGER Lab\, http://uwbadgerlab.engr.wisc.edu). \nDr. Adamczyk's research aims to enha nce physical and functional recovery from impairments affecting walking\, running\, and standing. Core foci include basic research on locomotion b iomechanics\; design of semi-active foot prostheses for gait restoration after amputation\; wearable sensors for movement assessment during real-l ife activities\; and rehabilitation robotics to explore motor learning an d neural adaptation in the lower limb.

Fitzpatrick C IEMAS Pre-Function Area CREATED:20221215T211308Z DESCRIPTION:Complex\, three-dimensional (3D) micro/nanostructures in biolo gy provide sophisticated\, essential functions in even the most basic for ms of life. Compelling opportunities exist for analogous 3D structures i n man-made devices\, but existing design options are highly constrained b y comparatively primitive capabilities in fabrication and growth. Recent advances in mechanical engineering and materials science provide broad ac cess to diverse\, highly engineered classes of 3D architectures\, with ch aracteristic dimensions that range from nanometers to centimeters and are as that span square centimeters or more. The approach relies on geometri c transformation of preformed two-dimensional (2D) precursor micro/nanost ructures and/or devices into extended 3D layouts by controlled processes of substrate-induced compressive buckling\, where the bonding configurati ons\, thickness distributions and other parameters control the final conf igurations. This talk reviews the key concepts and focuses on the most r ecent developments with example applications in areas ranging from mesosc ale microfluidic/electronic networks as advanced neural interfaces to bio -inspired microfliers as environmental sensing platforms.\n\nProfessor Jo hn A. Rogers obtained BA and BS degrees in chemistry and in physics from the University of Texas\, Austin\, in 1989. From MIT\, he received SM de grees in physics and in chemistry in 1992 and the PhD degree in physical chemistry in 1995. From 1995 to 1997\, Rogers was a Junior Fellow in the Harvard University Society of Fellows. He joined Bell Laboratories as a Member of Technical Staff and then served as Director of the Condensed M atter Physics Research Department from 1997 to 2002. He then spent thirt een years on the faculty at University of Illinois\, most recently as the Swanlund Chair Professor and Director of the Seitz Materials Research La boratory. In the Fall of 2016\, he moved to Northwestern University wher e he is Director of the recently endowed Querrey-Simpson Institute for Bi oelectronics.

Even though\, we are surr ounded by natural and man-made porous materials\, a fundamental understan ding of the complex physics and behavior of many porous structures remain s unknown. This lack of knowledge is mainly due to their complex\, hetero geneous structures and limited experimental capabilities to capture their behaviors across multiple temporal and spatial scales. In this talk\, I will begin by providing an overview of porous materials and their substan tial role in engineering and scientific communities. I will then discuss some of our recent efforts in developing novel multiscale numerical tools combined with phase-filed fracture method as well as a newly developed a symptotic homogenization method to capture effective properties of porous media subjected to multi-physics processes. I will conclude the talk by how we can accelerate scientific discoveries in porous media by integrati ng novel numerical tools and advanced experimental capabilities.

We have been asking how one can program the evolution of synthe tic materials using designed chemical networks analogous to the biologica l networks that regulate cell and tissue architecture. In these systems\, the dynamical evolution of molecular programs\, or reaction processes\, drive the evolution of the environment where materials assembly and act. This work thus amounts to controlling the pathways of assembly and recon figuration. Molecular programs can comprise tens of species whose interac tions are kinetically controlled\, providing many new levers for controll ing material formation and metamorphosis. These methods are thus promisin g routes toward building radically new materials that could grow into spe cific shapes\, heal\, or adapt to their environments. \n\nI will descri be our recent work focused on controlling the dynamic assembly and shape change of biomolecular materials such as hydrogels and semiflexible polym er networks. Different biomolecular signals can induce different dynamic polymerization and depolymerization processes in these materials and how chemical networks can be coupled to these materials to induce dynamic ma terial behavior. To understand what new behaviors can arise in these syst ems when the chemical networks that regulate them become large and comple x\, we have recently developed integrated synthetic in vitro genetic regu latory networks consisting of oligonucleotide templates\, T7 RNA polymera se and an RNase. These networks can consist of tens of different interco nnected network elements\, making it possible to construct synthetic regu latory networks of complexities comparable to those of simple viruses\, e nabling stepwise\, multifaceted regulation of materials and chemistry.

The first focuses on topology optimizat ion of structures subjected to random dynamic loads. Nearly all approach es to date only consider static deterministic loads. However\, many of th e most severe dynamic loads that civil structures must withstand are rand om and dynamic in nature. A general topology optimization framework is pr esented to accommodate directly the random dynamic nature of the excitati on and the responses. The proposed framework is illustrated for seismical ly excited and wind excited buildings\, as well as bridges subjected to r andom traffic loading. The results demonstrate the efficacy of this appro ach for efficient topology optimization of buildings subjected to stochas tic dynamic loads. The second part of the seminar discusses recent advanc es in computer vision techniques as they apply to the problem of civil in frastructure inspection and monitoring. Inspection applications presented include identifying context such as structural components\, characterizi ng local and global visible damage\, and detecting changes from a referen ce image\, with focus on rapid structural condition assessment of buildin gs and bridges after disasters. Monitoring applications discussed include static measurement of strain and displacement\, as well as dynamic measu rements of displacement and modal analysis. Additionally\, promising area s of growth for research in the field of computer vision-based civil infr astructure inspection and monitoring. This research will ultimately lead to more effective performance of our civil infrastructure.

This is the case for transport aircraft\, unmanned aerial vehicles\ , and even missiles. Such designs are inherently flexible and susceptible to adverse aeroelastic phenomena\, such as excessive response to atmosph eric turbulence and flutter instability. Some very flexible configuration s bring new challenges as the traditional structural and aeroelastic mode ls are inadequate to describe their behavior. In the Aeroelasticity Labor atory at the Faculty of Aerospace Engineering\, we derive novel computati onal and experimental approaches to study very flexible wings and test me thodologies to assess their characteristics in flight. The talk will intr oduce some of our recent aeroelastic studies\, including a wind tunnel te st of an extremely flexible wing that deforms to 50% of its span under ae rodynamic loads and the Active Aeroelastic Aircraft Testbed (A3TB)\, a 3D -printed experimental vehicle for flutter suppression studies. \nProfesso r Daniella Raveh\, Technicon '92\, Ph.D. '99\, focuses her research in th e area of aeroelasticity\, the interaction between aerodynamic forces and flexible structures.

This seminar will discuss how materials ar e optimized for these applications\, as well as examples of the use of pi ezoelectric films over a wide range of length scales. The key figures of merit for actuators and energy harvesting will be discussed\, with emphas is on how to achieve these on practical substrates. For example\, control of the domain structure of the ferroelectric material allows the energy harvesting figure of merit for the piezoelectric layer to be increased by factors of 4 - 10. Likewise\, control of crystallographic orientation an d substrate clamping enables large increases in the figure of merit for a ctuators. To illustrate the functionality of these films\, examples of in tegration into MEMS structures will also be discussed\, including miniatu rized ultrasound systems for imaging and particle manipulation\, low freq uency and non-resonant piezoelectric energy harvesting devices\, and piez oelectronic transistors as a potential replacement for CMOS electronics.\ n \nSusan Trolier-McKinstry is an Evan Pugh University Professor and Stew ard S.

A stunning counterexample occurs in S. cerevisiae - the same yeast used to brew beer and make bread. When these yeast sense that they have run out of glucose to eat\, coexisting liquid phases appear within the lipid memb rane that surrounds one of their organelles. This phase separation is fun ctionally important\, enabling yeast survival during periods of stress. T his talk will review recent results showing: (1) This miscibility transit ion is reversible as would be expected from equilibrium thermodynamics\, even though it occurs in a living system. (2) Yeast actively regulate thi s phase transition to hold the membrane transition ~15C above the yeast g rowth temperature. (3) In cases when domains appear as stripes\, there is no current theory that explains all material properties and physical obs ervables of the system.

C urrent clinical workflow mostly relies on manual analysis of CMR images. Segmentation of different chambers\, mainly the left and right ventricles \, from CMR datasets is an essential step for calculation of clinical ind ices such as ventricular volume and ejection fraction. We present deep le arning methods and deformable models that can automatically segment CMR i mages and improve the accuracy and robustness. Training these models requ ires large annotated datasets\, which are not readily available particula rly for CHD patients. To mitigate this issue\, we devised a novel method that uses a generative adversarial network (GAN) to synthetically augment the training dataset via generating synthetic CMR images and their corre sponding chamber segmentations. Our methods outperform the existing techn iques presented in different MICCAI challenges and commercially available segmentation software. Finally\, we argue that distributed learning meth ods that train locally but build global models can increase the access by preserving the privacy. We discuss asynchronous federated learning metho ds that provide high precision while significantly reducing the data tran smitted during client-server interactions.

However\, approaches that are suc cessful at achieving molecular-scale control are often difficult to exten d across length scales\, or into challenging chemically heterogeneous env ironments required for real function. Here\, we describe a surprisingly r obust and scalable route to achieve nm-to-macroscopic chemical patterning of materials based on amphiphilic striped phases\, which can be assemble d on graphite\, graphene\, MoS2\, and other 2D materials. Recently\, we h ave also demonstrated that these patterns can be assembled on hard\, crys talline 2D materials\, then transferred to soft\, amorphous materials inc luding PDMS and hydrogels. The transferred surface layer of fully extende d\, relatively rigid polydiacetylenes with functional headgroups confers both chemical and mechanical function\, creating new opportunities for na nostructured material design in biology and wearable electronics.

We introduce a number of data-driven strategies for discovering nonlinear multiscale dynamical sy stems and their embeddings from data. We consider two canonical cases: (i ) systems for which we have full measurements of the governing variables\ , and (ii) systems for which we have incomplete measurements. For systems with full state measurements\, we show that the recent sparse identifica tion of nonlinear dynamical systems (SINDy) method can discover governing equations with relatively little data and introduce a sampling method th at allows SINDy to scale efficiently to problems with multiple time scale s\, noise and parametric dependencies. For systems with incomplete obse rvations\, we show that the Hankel alternative view of Koopman (HAVOK) me thod\, based on time-delay embedding coordinates and the dynamic mode dec omposition\, can be used to obtain a linear models and Koopman invariant measurement systems that nearly perfectly captures the dynamics of nonlin ear quasiperiodic systems. Neural networks are used in targeted ways to a id in the model reduction process. Together\, these approaches provide a suite of mathematical strategies for reducing the data required to discov er and model nonlinear multiscale systems.\nNathan Kutz is the Yasuko End o and Robert Bolles Professor of Applied Mathematics and Electrical and C omputer Engineering and Director of the AI Institute in Dynamic Systems a t the University of Washington\, having served as chair of applied mathem atics from 2007-2015.

However\, the statistical analysis and interpretat ion require careful attention.\nIn this talk I will discuss recently deve loped\, explainable AI methods [1\,2] and applications [3-5] that combine detailed\, consistent experimental data (called "clean data") with theor etical data for the identification of "rules" that determine the properti es and functions of materials. These "rules" depend on descriptive parame ters\, called "materials genes". In analogy to genes in biology they are correlated with a certain material property or function. Thus\, these mat erials genes help the identification of materials that are\, for example\ , better electrical conductors or better heat insulators or better cataly sts.\n\n(*) Work done in collaboration with Lucas Foppa\, Thomas Purcell\ , et al.\n1.

It can be probed by vibrational sum-frequency generatio n (vSFG) spectroscopy as well as ultrafast time-resolved vSFG. Combined with computational tools\, such as molecular dynamics simulations\, a mic roscopic understanding of interfaces can be approached. Our experiments show that in the absence of surface charge (pH 2)\, water at silica surfa ces exhibits significantly slower OH stretch vibrational relaxation (~600 fs) compared to bulk water. However\, at charged silica surfaces (e.g.\ , pH 6)\, bulk-like fast dynamics (~200 fs) are observed at low ionic str ength. This decelerates to ~600 fs with the addition of NaCl. In parall el\, vSFG results demonstrated that silica interfacial water structure is most sensitive to ions at pH=6-8\, correlating with the known salt and p H dependence of silica surface reactivity. Consequently\, it is unclear whether the observed slowing of the vibrational dynamics is due to the re duction in the Debye length\, or because of changes in the local hydrogen bonding environment caused by the electrolyte and how this might depend on the identity of the ions or the solid surface. The combination of mol ecular dynamics simulations with spectroscopic and time-resolved vSFG exp eriments on aqueous Al2O3 interfaces\, along with the use of a molecular probe (SCN-)\, sheds light on the ongoing debate on the role of ions in i nterfacial water structure and the hydrogen bonding network\, as well as whether the observed behavior is specific to silica/water interfaces or c an be generalized to other aqueous interfaces.

In the context of these energy applications\, i t is necessary to understand factors that control the kinetics and select ivity of electrochemical reactions. At the electrode level\, many factors \, including the chemical composition\, atomic or molecular structure\, s urface area\, and morphology\, have been leveraged to direct electrochemi cal reactions. An emerging strategy is to geometrically confine the elect rochemical reaction within a porous electrode material. This places a phy sical boundary around the electrochemical reaction and thus defines the r eaction microenvironment\, while also spatially restricting the reactants and products. Experimental studies of nanoconfinement effects on electro chemical reactions require electrochemical interfaces with well-defined e nvironments. In this presentation\, I will discuss our materials chemistr y approach to define the confined electrochemical environment within mole cularly pillared transition metal oxides\, and our study of electrochemic al reactions taking place within these electrodes using in situ and opera ndo electrochemical methods.

Emulsions are biphas ic systems in which droplets of one liquid (e.g.\, oil) are dispersed in a continuous phase of another (e.g.\, water)\, and those stabilized by pa rticles are called Pickering emulsions. These phase-separated systems pro vide an ideal platform for the synthesis of composites of disparate mater ials when combined with polymerizations. Specifically\, the Pentzer group developed 2D particle surfactants that could be used for different fluid -fluid interfaces\, including oil-water\, oil-oil\, and ionic liquid-oil\ , and they combine the high interfacial area with simple polymerizations to fabricate hybrid structures. For example\, organization of polymers at the fluid-fluid interface can produce liquid-filled capsules for carbon capture or thermal energy management\, as well as functional additives fo r additive manufacturing. This presentation will describe the production of polymer composites including porous scaffolds\, stabilized bubbles\, c apsules of functional liquids\, and polymer particles armored with inorga nic particles\; the impact of composition and architecture will be discus sed\, focusing on direct air capture of CO2 and thermal energy management .\n\nBio.: EMILY PENTZER is Professor of chemistry materials science and engineering\, and chemical engineering at Texas A&M University\, where sh e also serves as Associate Dean of Research for the College of Arts and S ciences. She received a BS in chemistry from Butler University (2005) and PhD in chemistry from Northwestern University (2010)\, where her thesis focused on preparing and polymerizing unsaturated lactones and lactams. S he then worked with Professor Todd Emrick in the Polymer Science and Engi neering Department at UMass Amherst where she focused on the synthesis an d assembly of electronically active materials for organic photovoltaics. In 2013\, Dr. Pentzer started her independent career as an assistant prof essor of chemistry at Case Western Reserve University and she moved to Te xas A&M in 2019.

Epstein\, R.C. Mac laurin Professor of Aeronautics and Astronautics Emeritus (MIT)\, who wil l give a talk entitled\, "Batteries\, Airliners\, and Money."\n\n\nABSTRA CT: In recent years there has been much excitement over the possibility o f battery energy storage replacing aircraft fuel\, both to reduce aviatio n's environmental impact and to enable new civil aviation markets. Intere st in commuter\, regional\, and narrowbody airliners has been driven by g lobal warming concerns\, while excitement over electric Vertical Takeoff and Landing (eVTOL) aircraft is focused on opening new markets for aviati on. Since the useful energy density of current batteries are more than an order of magnitude lower than that of fuels now used or contemplated\, m uch attention has been paid to the battery energy density needed to yield ranges useful in various aircraft markets. This lecture examines how cha racteristics of known battery chemistries can influence electric aircraft design\, cost\, and environmental impact. The focus is on battery power for scheduled airlines since they produce the vast majority of aviation's environmental impact. Themes include the importance of operational const raints on economics\, the treatment of uncertainty in engineering decisio n making\, and how technology might change the outcome.\n\nBIO: DR.

This talk w ill present recent work developing nanoengineered hierarchical advanced ( aerospace-grade) composites with enhanced mechanical properties\, with a focus on imparting multifunctionality. Such hybrid advanced composites em ploy aligned nanofibers (in most of our work\, aligned carbon nanotubes\, A-CNTs) in several architectures to enhance \\ bulk properties of existi ng aerospace-grade advanced composites. Building multifunctionality concu rrent with these mechanical property improvements includes thermal and el ectrical conductivity tailoring for ice protection\, damage sensing\, and self-manufacturing\, among others. For example\, out-of-oven (OoO) manuf acturing utilizes conductive heating from flexible nanostructured CNT fil ms to conductively\, rather than convectively\, heat the composite\, resu lting in 2-3 orders of magnitude reduction in required energy\, opening u p new possibilities in areas such as accelerated curing\, autoclave-free processing\, and cure sensing. Fundamental studies on polymer-nanofiber i nteractions via variable-volume fraction (vol%) A-CNT polymer nanocomposi tes\, including processing limits to ultra-high vol% systems\, led to the development of a combined top-down and bottom-up fabrication methodology that addresses several of the key issues (agglomeration\, viscosity\, sc ale\, alignment) that have frustrated the use of nanomaterials in bulk ma terials. New research in related areas including carbon nanostructure cat alysis\, nanomaterials in microelectronics and energy storage\, 3D damage progression via x-ray tomography\, and new work in boron nitride nanotub es (BNNTs) will be introduced if time allows.

These material technologies are composed almost entirely out of soft matter - elastomers\, gels\, an d conductive fluids like liquid metal - and represent the building blocks for machines and electronics that are soft\, flexible\, and stretchable. Because of their intrinsic compliance and elasticity\, such devices can be incorporated into soft\, biologically-inspired robots or be worn on th e body and operate continuously without impairing natural body motion. In this talk\, Majidi will review recent contributions from his research gr oup in creating soft multifunctional materials for wearable electronics a nd soft robotics using these emerging practices in "soft-matter engineeri ng" with a focus on soft robots powered using shape memory materials and soft material architectures for highly stretchable digital electronics\, wearable energy harvesting\, and electrically-responsive actuation. In ad dition to describing the synthesis and properties of these materials\, Ma jidi will highlight several systems-level implementations that demonstrat e their practical use in robotics\, bioelectronics\, and human-computer i nteraction.\n\nBIO: CARMEL MAJIDI is the Clarence H. Adamson Professor of Mechanical Engineering at Carnegie Mellon\, where he leads the Soft Mach ines Lab dedicated to the discovery of novel material architectures that allow machines and electronics to be soft\, elastically deformable\, and biomechanically compatible. Currently\, his research is focused on model ing\, design\, and control of soft robotic systems as well as the develop oment of multifunctional materials that exhibit unique combinations of me chanical\, electrical\, and thermal properties and can function as "artif icial" skin\, nervous tissue\, and muscle.

Reception to follow.\n\nTitle: \nBioelastic State Recovery for Haptic Sensory Substitution\n\nAbstract: \nThe rich se t of mechanoreceptors found in human skin offers a versatile engineering interface for transmitting information and eliciting perceptions\, potent ially serving a broad range of applications in patient care and other imp ortant industries. Targeted multisensory engagement of these afferent un its\, however\, faces persistent challenges\, especially for wearable\, p rogrammable systems that need to operate adaptively across the body. Her e\, we present a miniaturized electromechanical structure that\, when com bined with skin as an elastic\, energy-storing element\, supports bistabl e\, self-sensing modes of deformation. Targeting specific classes of mec hanoreceptors as the basis for distinct\, programmed sensory responses\, this haptic unit can deliver both dynamic and static stimuli directed as either normal or shear forces. Systematic experimental and theoretical s tudies establish foundational principles and practical criteria for low-e nergy operation across natural anatomical variations in the mechanical pr operties of human skin. A wireless\, skin-conformable haptic interface\, integrating an array of these bistable transducers\, serves as a high-de nsity channel capable of rendering input from smartphone-based 3D scannin g and inertial sensors. Demonstrations of this system include sensory su bstitution designed to improve the quality of life for patients with visu al and proprioceptive impairments.\n\nBio: \nYonggang Huang is the Achenb ach Professor of Mechanical Engineering\, Civil & Environmental Engineeri ng\, and Materials Science & Engineering at Northwestern University.

These goals target major carbon reductions to full\, net-zero requirements over the next quarter century. While 26 years may seem like an extended timetable\, as an energy industry there are many c hallenges to overcome in a short period of time to realize these goals. To ensure reliable\, resilient\, and affordable energy\, it is imperative to bolster a mix of generation and source options. It is clear renewable s alone\, even with battery storage\, will not meet the needs of society. Clean energy sources like Nuclear and dispatchable generation using low- carbon fuels or carbon capture are needed as well. Specifically for Gas Turbines\, low-carbon fuel options are of strong interest around the worl d. Typically\, most will point to hydrogen\; however\, ammonia is a stro ng candidate for some areas along with renewable liquid fuels playing a l arge part. This seminar will focus on research from around the world aime d at developing additional capabilities for gas turbines\, specifically h ighlighting NOx emissions. Demonstration data will also be shared to help translate laboratory testing to the real-world along with effects on com bustion dynamics and operability range implications.\n\nBOBBY NOBLE is th e Senior Program Manager for the Gas Turbine R&D at EPRI. He is responsib le for the gas turbine research area\, where he and his team work on topi cs involving all aspects of the gas turbine system. His primary gas turbi ne expertise is in gas turbine combustion\, with focus on combustion dyna mics\, hydrogen and other renewable fuels\, along with next-generation\, low-NOx combustor architectures. He's instrumental in gas turbine health and performance analytics developments\, including digital twins. Mr. Nob le is an ASME Fellow with more than 20 years of experience in the gas tur bine and power industry. He's the 2024 ASME Westinghouse Silver Medal rec ipient.

"\n\nAbstract: As chemists and materials scientists\, it is our duty to s ynthesize and utilize materials for a multitude of applications that prom ote the development of society and the well-being of its citizens. Since the inception of metal-organic frameworks (MOFs)\, researchers have propo sed a variety of design strategies to rationally synthesize new MOF mater ials\, studied their porosity and gas sorption performances\, and integra ted MOFs onto supports and into devices. MOFs are a class of porous\, cry stalline materials composed of metal-based nodes and organic ligands that self-assemble into multi-dimensional lattices. In contrast to convention al porous materials\, an abundantly diverse set of molecular building blo cks allows for the realization of MOFs with a broad range of properties. Efforts have explored the relevance of MOFs for applications including\, but not limited to\, heterogeneous catalysis\, guest delivery\, water cap ture\, destruction of nerve agents\, gas storage\, and separation. For ex ample\, we have developed an extensive understanding of how the physical architecture and chemical properties of MOFs affect material performance in applications such as catalytic activity for chemical warfare agent det oxification. Recently\, start-up companies have undertaken MOF commercial ization within industrial sectors. ION-X™ is used in this talk as an exam ple to show case the way NuMat Technologies is innovating at the intersec tion of molecular design and precision engineering\, to build the product s driving the industries of tomorrow.\n\nBIO: Omar K.

To meet volatile needs\, there is a growing demand for integrative thinking. Integrative thinking is systematically integrating disparate disciplines to effective ly tackle complex engineering problems. For decades\, the field of Smart Materials and Structures has fostered an integrative mindset - it is in o ur DNA. While emerging technologies based upon smart materials hold many benefits for industry\, it has been a long journey to transition research advancements into real products. The field of smart materials and struct ures is viewed as "enabling" or "emerging" spanning either a) new markets where the products are first generation without a clear application and there is an absence of design models present so empirical developmental m ethods must be employed\, or b) developing markets where there are a few guiding models/methods but the products are not optimized and not reachin g their full commercial potential. ... There needs to be a clearer path t o transition all the progress made during the past twenty-five years of r esearch into fruitful commercial products\, especially within high-volume \, low-cost markets. This talk will discuss these efforts from a technolo gical design and development perspective with application examples from s everal industries such as 1) Medical industry with Liftware spoon to coun teract hand tremor and FDA fast track MENDD treatment for bowel growth\, and 2) Automotive industry with Soft Adaptive Structures for deployable i nterior and exterior features in autonomous vehicles. The importance of c ollaborative\, synergistic mission-driven relationships spanning from bas ic research to device design into system integration will be highlighted as crucial for successful transition from emerging smart material researc h of today to competitive commercial products of tomorrow.

In additive manufacturing (AM)\, the fabrication of parts and objects with high complexity and high performance is advantageous over other methods. Using nanocomposites ena bles highly improved properties even with "commodity polymers" that do no t need to undergo high-temperature processes or extensive reformulation. With artificial intelligence and machine learning (AI/ML)\, optimizing th e formulation and manufacturing methods is possible. Using sensors capabl e of a feedback loop mechanism and the ability to use simulation to creat e digital twins\, optimizing properties in record time is possible. Stati stical and logic-derived design\, including regression analysis\, are sta rting points for designing experiments (DOE) or principal component analy sis(PCA) in optimization and analysis vs trial-and-error approaches when working with polymer materials. In this talk\, we demonstrate the approac hes toward understanding Nanostructuring in composites and hierarchical a pproaches in optimization via AI/ML and other training/learning sets for specific properties and applications\, such as 3D printing and flow chemi stry reactions. Introducing more sensors (monitoring instruments) in AM p rocesses and real-time ML with online monitoring allows a feedback loop a nd deep learning (DL) for autonomous fabrication and data analytics.

Future missions with larger and heavier rovers will require bigge r parachutes and inflatable drag devices\, necessitating advanced simulat ions using high-fidelity\, multi-disciplinary computational models for su personic parachute inflation dynamics (SPID). These models must address c omplex factors\, including shocks\, turbulence\, porous flow boundary con ditions\, the behavior of fabric materials\, extensive contact between th in surfaces\, and highly nonlinear fluid-structure interactions amid topo logy changes.\nThis lecture presents research conducted at Stanford Unive rsity in collaboration with NASA Ames and the Jet Propulsion Laboratory t o develop these computational models and highlights several associated in novations. Key advancements include a multi-scale approach for modeling w oven fabric dynamics through locally attached microstructures and mechani cs-informed machine learning\, a total variation diminishing method for s olving multi-material flow problems while eliminating spurious oscillatio ns\, a subgrid scale modeling technique for porous wall boundary conditio ns\, and an energy-conserving discretization method for fluid-structure t ransmission interfaces of disparate spatial dimensions.\nAdditionally\, t he lecture will report validation results from simulating the SPID of par achutes tested during NASA's 2018 ASPIRE mission\, which informed the par achute design selection for the Mars 2020 mission that successfully lande d Perseverance on February 18\, 2021.\n\nCHARBEL FARHAT is the Vivian Chu rch Hoff Professor of Aircraft Structures at Stanford University's School of Engineering\, where he chaired the Department of Aeronautics and Astr onautics from 2008 to 2023.

Traditi onally\, this process requires cryogenic conditions to suppress dephasing \, as the emergence of coherence demands that the collective light-matter coupling outpace decoherence processes.\n\nIn this talk\, I will present the discovery of an unconventional form of SF that persists at room temp erature in lead-halide perovskites\, enabled by the formation of solitons -self-organized quantum islands of coherence embedded in an incoherent ba ckground. These solitonic regions act as localized macroscopic quantum st ates that are vibrationally isolated from the thermal lattice via a mecha nism we term Quantum Analog of Vibration Isolation (QAVI). While conventi onal SF relies on radiative coupling to induce phase synchronization\, so litonic SF emerges from a nonlinear\, density-driven structural transitio n governed by exciton-lattice interactions.\n\nThis phenomenon not only c hallenges long-standing assumptions about coherence limits in solids\, bu t also points to a broader framework for realizing macroscopic quantum ph ases in thermally disordered environments-where self-localization and col lective order can coexist without global symmetry breaking.\n\nKenan Gund ogdu received his B.S. in Physics from Boğaziçi University in 1999 and hi s Ph.D. in Physics from the University of Iowa in 2004\, where he studied spin dynamics in semiconductors. He completed two postdoctoral appointme nts-first in the Chemistry Department at the University of Iowa and then at the Massachusetts Institute of Technology. Since 2008\, he has been a faculty member in the Department of Physics at North Carolina State Unive rsity. His research focuses on ultrafast spectroscopy\, quantum coherence \, and emergent phenomena in quantum materials\, including recent work on room-temperature solitonic superfluorescence in lead-halide perovskites.
