Engineering & Materials S cience SPRING 2024 Seminar Series with Dr. Jerry Qi\, Professor of Mechan ical Engineering at Georgia Institute of Technology speaks on "Multimater ial Additive Manufacturing toward \nShape Morphing Structures and 4D Prin ting."\n\nABSTRACT: 3D printing (additive manufacturing\, AM) where mater ials are deposited in a layer-by-layer manner to form a 3D solid has seen significant advances in recent decades. 3D printing has the advantage in creating a part with complex geometry from a digit file\, making them an ideal candidate for making architected materials. Multimaterial 3D print ing is an emerging field in recent years in additive manufacturing. It of fers the advantage of placement of materials with different properties in the 3D space with high resolution\, or controllable heterogeneity. In th is talk\, we present our recent progress in developing multimaterial addi tive manufacturing methods. In the first approach\, we present a new deve lopment where we integrate two AM methods\, direct-ink-write (DIW) and di git light processing (DLP) into one system. In this system\, the DLP can be used to print complex bulk parts while DIW can be used to print functi onal inks. In the second approach\, we recently developed a grayscale DLP (g-DLP) 3D printing method where we can print a part with gradient mater ial properties. We further explore how to use multimaterial 3D printing t o fabricate shape morphing structures\, including direct 4D printing of 2 D lattice structures\, lattice structures with changing shape driven by l iquid crystal elastomers\, and 3D lattice structures by gradient material s. \n\nBIO: JERRY QI is professor of Mechanical Engineering at Georgia T ech and is site director of NSF IUCRC on Science of Heterogeneous Additiv e Printing of 3D Materials (SHAP3D). He received his undergrad and gradua te degrees from Tsinghua University and a ScD degree from MIT. After one- year postdoc at MIT\, he joined Univ. of Colorado Boulder as an asst. pro fessor and moved to Georgia Tech in 2014. Prof. Qi's research is in the b road field of nonlinear mechanics of polymeric materials and focuses on d eveloping fundamental understanding of multi-field properties of soft act ive materials through experimentation and constitutive modeling then appl ying these understandings to application design.

Simultaneously\, wastewater-associated pathogens hav e become a critical public health monitoring tool via wastewater-based su rveillance (WBS). Molecular (i.e.\, DNA- or RNA-based) methods such as qP CR\, digital PCR\, and metagenomics have a critical role in contributing to water quality monitoring and WBS. I will begin this talk by discussing our group's contributions to metagenomic methods for water quality monit oring\, including developing quantitative metagenomic methods and employi ng metagenomics to develop a new viral fecal indicator\, crAssphage. I wi ll then discuss our group's work on WBS\, including initial developments for COVID-19 and recent efforts on novel disease targets\, including MPox and malaria.\n\nDr. Kyle Bibby is a Professor and Associate Department C hair at the University of Notre Dame in the Department of Civil and Envir onmental Engineering and Earth Sciences.

Its broad utility arises from the unparalleled spatiotemporal control ove r chemical transformations that it offers. However\, contemporary methods rely on high energy UV light (<400 nm)\, which limits material compatibi lity due to pervasive degradation and attenuation that occurs upon non-se lective absorption and/or scattering. Excitingly\, the recent commerciali zation of inexpensive light emitting diodes has opened an avenue to exami ne mild visible-to-near infrared induced reactions in materials chemistry . This presentation will focus on how the Page Research Group has develop ed and leveraged low energy light driven polymerizations to generate a ve rsatile array of soft materials with unprecedented speed and spatiotempor al precision. Specifically\, catalyst design principles to enable rapid s olidification of photopolymer resins using visible-to-near infrared light will be discussed\, along with their utility and optimization in high re solution additive manufacturing towards all-polymer multimaterial composi tes.

It is a saga of flawed derivations\, and a tra gedy of proliferation of errors\; but it is also an exciting account of h ow the anomalies were finally discovered and corrected (yielding equation s simpler than the original\, incorrect ones). It is a drama of how some researchers at first denied the truth\, but later came to repentance and forgiveness\; and\, finally\, it is an account of how lasting friendships were initiated.

And\, yes\, the speaker was also intimately involved in the sag a. Although the story spans 1899 - 1979 and\, although it came to closur e over 40 years ago\, the lessons learned are as important to the modern researcher as they were to those of us who experienced this true tale.\n\ nBIO: PROFESSOR DAVID PETERS first joined the faculty of Washington Unive rsity in St. Louis (WashU) in 1975. Prior to that\, he was an associate e ngineer at McDonnell Douglas Astronautics Co. in St. Louis from 1969-1970 and a research scientist in the Army Air Mobility R&D Laboratory from 19 70-1975.\n\nProfessor Peters left WashU to join the faculty of Georgia Te ch in 1985 but returned in 1991. Professor Peters served as the Chair of the WashU Department of Mechanical Engineering from 1982-1985 and from 19 97-2007. Currently\, he is the Associate Director of Georgia Tech/Washing ton University in St. Louis Center of Excellence for Rotor Technology.

However\, t heir employment in scientific machine learning with the purpose of learni ng physics of complex system is less explored. Differs from the other mac hine learning tasks such as the computer vision and natural language proc essing problems where a large amount of unstructured data are available\, physics-based machine learning tasks often feature scarce and structured measurements.\n\nIn this talk\, we will take the learning of heterogeneo us material responses as an exemplar problem\, to investigate the design of neural networks for physics-based machine learning. In particular\, we propose to parameterize the mapping between loading conditions and the corresponding system responses in the form of nonlocal neural operators\, and infer the neural network parameters from high-fidelity simulation or experimental measurements. As such\, the model is built as mappings betw een infinite-dimensional function spaces\, and the learnt network paramet ers are resolution-agnostic: no further modification or tuning will be re quired for different resolutions in order to achieve the same level of pr ediction accuracy. Moreover\, the nonlocal operator architecture also all ows the incorporation of intrinsic mathematical and physics knowledge\, w hich improves the learning efficacy and robustness from scarce measuremen ts.\n\nTo demonstrate the applicability of our nonlocal operator learning framework\, three typical scenarios in physics-based machine learning wi ll be discussed: the learning of a material-specific constitutive law\, t he learning of an efficient PDE solution operator\, and the development o f a foundational constitutive law across multiple materials. As an applic ation\, we learn material models directly from digital image correlation (DIC) displacement tracking measurements on a porcine tricuspid valve lea flet tissue\, and show that the learnt model substantially outperforms co nventional constitutive models.

Herein\, we examine learning problems in signal processing t hat are inherently hard without key side information. In particular\, we exploit necessary resolution limits for classical compressed sensing prob lems. To limit an eavesdropper's capabilities\, we create an environment for the eavesdropper wherein the appropriate compressed sensing algorithm would provably fail. The intended receiver overcomes this ill-posed prob lem by leveraging secret side information shared between the intended tra nsmitter and receiver. Two scenarios are considered: one for communicatio n over a wireless channel where a novel block-sparsity based signaling st rategy is employed and one for localization where novel structured noise is introduced to degrade the form of the eavesdropper's channel. In the l atter scenario\, the transmitter designs a beamformer that introduces spu rious paths\, or spoofs the line-of-sight path\, in the channel without h aving access to the channel state information. Both far-field and near-fi eld cases are considered for the private localization. In both private co mmunication and private localization\, the amount of secret information t hat must be shared is very modest. Theoretical guarantees can be provided for both cases. Proposed algorithms are validated via numerical results. \n Biography: Urbashi Mitra received the B.S. and the M.S. degrees from the University of California at Berkeley and her Ph.D. from Princeton Uni versity.

These properties are also displayed by the solutions of landscape evolution modes (LEMs)\, when fluvial erosion dominates over th e smoothing tendency of diffusion (i.e.\, soil creep). Under such conditi ons\, an invariant self-similar regime is reached where the average lands cape properties become independent of the balance between fluvial erosion and soil diffusion. In the vanishing limit\, diffusion remains crucial a nd localized in valleys and ridges where abrupt slope changes occur (as s hock waves). \nWE illustrate how focusing on the essential elements that distinguish landscape evolution\, minimalist LEMs become amenable to dime nsional analysis and other methods of nonlinear field equations\, used fo r example in fluid mechanics and turbulence\, offering fertile ground to unveil distinct dynamic regimes (e.g.\, unchannelized\, from incipient va lley formation\, transitional and statistically self-similar fractal regi me)\, and properly formulate questions related to the existence of steady state solution (as opposed to a situation of space time chaos\, similar to a geomorphological turbulence). We also explore the parallelism betwee n the landscape self-similarity and the self-similarity of fully develope d turbulent flows and discuss challenges for evaluating numerical simulat ion and novel avenues for numerical methods\, as well as ways to bridge b etween spatially discrete models (i.e.\, river networks) and continuous\, partial-differential-equation models.\n\nPorporato\, A.

Despite tremendous progress\, the performanc e of all-solid-state metal batteries remains unsatisfactory. In this semi nar\, I will present the key challenges confronting all-solid-state batte ries\, ranging from fundamental knowledge gap in understanding major fail ure mechanisms to issues in solid-state battery manufacturing issues. The complex origins of battery failure necessitate multimodal tools capable of quantifying void and dendrites\, identifying chemical and mechanical p roperties and monitoring the processes in situ. We have developed a suite of methods for structural\, chemical\, and mechanical characterizations that include operando-SEM\, ToF-SIMS\, and nanoindentation-based stiffnes s mapping. Materials innovations are equally important. We show how soft organic redox materials could enable intimate interfacial contact with so lid electrolytes under low operating pressure. Additionally\, we have dev eloped an oxysulfide glass electrolyte that forms a thin\, dense\, self-l imiting interphase against Na metal and exhibits a fully dense glass micr ostructure. We investigated the role of an interlayer between a lithium m etal anode and solid electrolyte that prevents lithium dendrite formation and allow reversible lithium plating and stripping over 2500 cycles. Fin ally\, we will discuss our recent efforts in battery manufacturing and th e establishment of a battery prototyping facility at UH.

Chronic wounds are often associated with bacterial and biofilm infections and have significantly impaired healing\, accounting for an estimated $2 5 billion annual burden on the US healthcare system. In wound infections\ , biofilms are bacterial communities encased in an extracellular polymeri c substance (EPS) adherent to biotic or abiotic surfaces. Treatment of bi ofilms is challenging based on their recalcitrant behavior towards antimi crobials and host-defenses due to the multi-factorial evasion strategies. Our team has developed a silk-based\, printed\, flexible electroceutical dressing that not only disinfects wounds by killing bacterial biofilms b ut also has shown evidence for healing chronic injuries in animal models. Additionally\, our electroceutical dressing inhibits formation of biofil ms in laboratory-scale gel models. Moreover\, our electroceutical\, Smart Platform for Engineered Electroceutical Dressings (SPEEDs)\, works with a disposable battery pack to provide a constant potential power source fo r direct current (DC) flow making it suitable for a small-form factor\, l ight-weight\, and portable system. SPEEDs have also been integrated with impedance sensing to remotely monitor wound state. We have evaluated SPEE Ds extensively\, both in vitro and in vivo. In vitro evaluation shows bac terial biofilms grown on agar gel (Pseudomonas aeruginosa and Staphylococ cus aureus) were killed with a 24-hour continuous treatment with SPEEDs. The SPEEDs were also found to be effective in eliminating antibiotic tole rant bacteria.

In this talk\, I w ill describe a breakthrough in additive manufacturing-3D printing-referre d to as Continuous Liquid Interface Production (CLIP) technology (Science 2015). CLIP\, and its recently introduced cousin injection CLIP (iCLIP\ ; Science Advances 2022)\, embody a convergence of advances in software\, hardware\, and materials to bring the digital revolution to the design a nd manufacturing of polymeric products. CLIP uses software-controlled che mistry to produce commercial quality parts rapidly and at scale by capita lizing on the principle of oxygen-inhibited photopolymerization to genera te a continual liquid interface of uncured resin between a forming part a nd a printer's exposure window. Instead of printing layer-by-layer\, this allows layerless parts to 'grow' from a pool of resin\, formed by light. Compatible with a wide range of polymers\, CLIP opens major opportunitie s for innovative products across diverse industries. Previously unmakeabl e products are already manufactured at scale with CLIP\, including the la rge-scale production of running shoes by Adidas (Futurecraft 4D)\; mass-c ustomized football helmets by Riddell\; the world's first FDA-approved 3D printed dentures\; and numerous parts in automotive\, consumer electroni cs\, and medicine. At Stanford\, we are pursuing new advances including d igital therapeutic devices in pediatric medicine\, new multi-materials pr inting approaches\, recyclable materials\, and the design of a high-resol ution printer to advance technologies in the microelectronics and drug/va ccine delivery areas\, including novel microneedle designs as a potent va ccine delivery platform and for the sampling of interstitial fluids for h ealth monitoring and the early detection of disease. \n\nJOSEPH M.

Also abundant in these systems are biofilms\, or bacteria surrounded w ith extracellular polymeric substances (EPS) to form a three-dimensional matrix structure. There is compelling evidence indicating nanoparticle (N P) ubiquity\, accumulation\, and interaction with environmental biofilms. However\, the fundamental understanding of the exact mechanisms governin g the interaction between nanoparticles and biofilms is still unclear. He rein\, we present a study to explore the effect of crosslinking density o n the diffusive behavior of NPs in heterogeneous matrices like alginate. With advanced analysis of fluorescence microscopy data\, we characterized and map the heterogeneous diffusion of 20\, 100\, and 200 nm carboxylate d-polystyrene nanoparticles in a calcium cross-linked alginate model matr ix of varying concentrations. Our findings showed that an increase in cro ss-linking concentration decreases NP diffusion and pore accessibility in a size-dependent manner. In addition\, all sizes of particles experience d a degree of confinement and partial confinement\, leading to the conclu sion that NP diffusion in heterogeneous matrices\, like alginate and the extracellular polymeric substances (EPS) matrix of a biofilm\, is anisotr opic due to the spatial heterogeneities and micro-domains present in the EPS structure.

Through adequate pre-stressing of their string members\, tensegrity structures ge nerally become mechanically stable. Traditional approaches for modeling t heir behavior assume that (i) bars are perfectly rigid\, (ii) cables are linear elastic\, and (iii) bars experience pure compression and strings p ure tension. In addition\, a common design constraint is to assume that t he structure would fail whenever any of its bars reaches the correspondin g Euler buckling load. In reality\, these assumptions tend to break down in the presence of dynamic events. In the first part of this talk\, we wi ll introduce a physics-based reduced-order model to study aspects related to the dynamic and nonlinear response of tensegrity-based planetary land ers. We will then adopt our model to show how\, under dynamic events\, bu ckling of individual members of a tensegrity structure does not necessari ly imply structural failure\, thus significantly expanding the design spa ce for such vehicles. In the second part of this talk\, we will show how lessons learned from our study of tensegrity planetary landers can be tra nslated into to the development novel metamaterials. We will introduce th e first known class-two 3D tensegrity metamaterial\, and show that this n ew topology exhibits unprecedented static and dynamic mechanical properti es.\n\nBIO: Julián J.

First\, linear microscopy methods lack the depth pe netration and optical sectioning required for deep-tissue recording\, whi le multiphoton microscopy allows for recording neuronal activity only fro m a single plane or few axially-shifted planes. In addition\, cellular-re solution recording requires a mouse to either be head-fixed under a micro scope or to have a miniaturized imaging device attached onto its skull. B oth can impact mouse behavior and underlying brain activity. Recently\, m y lab showed that utilizing an integrator for calcium-dependent recording of neuronal activity (CaMPARI) allows for cellular-resolution imaging of large-scale brain activity patterns in freely-behaving mice without need ing to attach any mechanical device. It was also shown that despite the e nhanced in vitro performance of the second generation of CaMPARI (CaMPARI 2)\, it exhibits poorer in vivo neuronal activity recording sensitivity w hen compared to CaMPARI1 in mice. Here\, we present an ongoing work to de velop a new generation of the CaMPARI sensor (CaMPARI3)\, which will over come the limitations of the previous generations. We developed an in vitr o-in vivo screening pipeline and found that the photoconversion propertie s of the same sensors in vitro and in vivo do not correlate. Rather\, the peak DF/F in vitro may better predict the rate of photoconversion in viv o. We present our progress with developing CaMPARI3\, which exhibits enha nced photoconversion and also the ability for recording dynamic changes i n neuronal activity. Therefore\, CaMPARI3 is expected to expand the possi ble experimental applications to record single-cell resolution brain acti vity from freely-behaving mice.\nHod Dana received his B.Sc. (summa cum l aude) and Ph.D. degrees in Biomedical Engineering from the Technion - Isr ael Institute of Technology. During his PhD work he developed advance non linear microscopy methods for recording of large-scale neuronal activity.

Thus\, to image the motion of excitons in their natural (quantum) time and length scales\, experime ntal approaches combining spatial and temporal resolutions are necessary. \n\nTo address this challenge\, my research group has developed the comb ined use of optical microscopy and ultrafast spectroscopy tools to image transport of excitons from the nanoscale to the mesoscale and over a wide range of temperatures. In my talk\, I will discuss our recent progress o n imaging environment-assisted quantum exciton transport in perovskite qu antum dot superlattices\, coherent suppression of exciton-exciton annihil ation in molecular aggregates\, and quantum phase transition of moiré exc itons. These results provide fundamental understandings of how excitons m igrate in materials and how these processes can be manipulated quantum me chanically. The unique ability to measure and control coherent pathways a re critical for both solar energy and quantum information applications.

Such autonomous agents are capable of handling dangerous tasks but are limited in their reactions to unforeseen events. At the same time\, humans have more adaptive and creative problem-solving skills but are lim ited in terms of handling some specific tasks and managing cognitive load s. The inclusion of autonomy within a team requires a significant effort to train agents to distribute tasks dynamically for optimal operation. In addition\, the need to address diverse requirements requires heterogeneo us teams where agents can have different capabilities and levels of risk tolerance. While heterogeneity in multi-agent teams offers benefits\, new challenges arise including how to find optimal heterogeneous team compos itions and how to distribute tasks dynamically among agents in complex op erations.\n\nThis presentation will discuss modeling tools for autonomous vehicles with focus on artificial intelligence algorithms for heterogene ous agents to learn dynamically task distributions in teams with humans a nd other autonomous agents through reinforcement learning in synthetic en vironments.\n\nBIO: Bogdan I.

Tahe r Abu Saif (UIUC)\, who will present the MEMS Distinguished Seminar entit led\, "Ultra-Sensitive MEMS Sensors Reveal a Biomechanics Link between Mi nd and Body."\n\nABSTRACT: For centuries\, the relation between mind and body has intrigued philosophers and scientists. How body affects the mind \, and mind affects the body? Since mid-19th century\, scientists searche d for the "mind" in the anatomy of brain\, just as they explored the "bod y" with Da Vinci's artistic renditions of muscles. Muscles are considered as contractile force actuators\, and neurons as information processors. Here\, we will discuss our findings\, revealed by a novel MEMS sensor\, t hat neurons are also contractile\, both in vivo and in vitro. This contra ctility leads to tension in axons\, a long cable-like structure that conn ects neurons with each other. We measure the magnitude and time evolution of tension in axons using specially designed MEMS force sensors. We then correlate the tension with neuronal function (firing pattern). We find t hat without this tension neurons cannot function. Furthermore\, we have p reliminary evidence of increased neuronal contractility with physical exe rcise\, revealing the first possible link between mind and body. Understa nding the critical role of neuron mechanics on neuron function may lead t o new therapies against mental diseases including anxiety\, depression\, dementia\, and Alzheimer's disease. \n\nM.

DNA nanodevices are particularly well-suited to interface with and manipulate biomolecules in vitro and in vivo because of the ability preci sely design nanodevice geometry\, functionalization (e.g. with interactio ns sites for biomolecules)\, and dynamic and mechanical properties. Our l aboratory focuses on two key areas of DNA nanotechnology: 1) design of mu lti-component and multi-device assemblies that can carry out robotic func tions like sensing and responding to the environment\; and 2) leveraging these capabilities to design DNA devices that can interface with and prob e biomolecular complexes. I will highlight our recent work on advancing d esign methods for multi-component assemblies and realizing cooperative fu nctions\, like shape changes or adaptive mechanical properties\, that eme rge from the behaviors and interactions of many dynamic devices. I will a lso highlight recent work in delivering DNA nanodevices into living cells . We recently developed methods to leverage a piggybacking approach to de liver DNA origami nanostructures to live cell nuclei\, where antibody lab eled DNA nanostructures target an RNA polymerase in the cytoplasm\, and t hen they are trafficked to the nucleus along with the polymerase. Moving forward we aim to use these devices as tools to probe and control molecul ar processes in living cells and deliver molecular payloads such as genes or other medicines.

Rheo-optical methods ar e used to quantify this alignment for high-density polyethylene (HDPE) an d poly(ether ether ketone) (PEEK). With both polymers\, the birefringence starts to be measurable at the same shear rate where shear flow starts t o accelerate crystallization kinetics. There is a strong departure from the Cox-Merz rule above this critical shear rate and at much higher shear rates\, the shear stress and birefringence both grow as the square root of shear rate\, as expected for nematic alignment of chains. Crystallizat ion from the flow-aligned nematic creates a fine-scale morphology that ma ximizes tie chains between crystals\, imparting toughness to these semicr ystalline polymers. \n\nPolymer chains stretch in shear flow when the she ar rate exceeds the reciprocal of their Rouse time. The high molecular w eight tail of the molecular weight distribution of HDPE is fit to an expo nential function that allows quantification of an energy conversion facto r E that is the volume fraction of chains that get stretched at any shear rate. The measured form birefringence of HDPE tracks perfectly with the shear rate dependence of E in the range 10-6 < E < 10-2. The product of E and specific work is shown to control the magnitude of the crystallizat ion acceleration from shear. When sheared below the equilibrium melting temperature\, HDPE forms a network of crystallization precursors that sta bilizes the melt against edge fracture.\n\nHost: Michael Rubinstein DURATION:PT1H DTSTAMP:20250904T151403Z DTSTART;TZID=America/New_York:20251015T120000 LAST-MODIFIED:20250904T151403Z LOCATION;X-BEDEWORK-UID=18832e99-20476e5b-0120-58864347-000000be:Fitzpatri ck Center Schiciano Auditorium Side A\, room 1464 STATUS:CONFIRMED SUMMARY:DMI/MEMS Seminar Presented by Prof. Ralph Colby UID:CAL-8a00ec8b-979413b9-0198-2ce42a6d-00005d47demobedework@mysite.edu X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Main:/user/public-user/Utili ties/Main X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Lecture_Talk:/user/public-us er/Lectures_Conferences/Lecture_Talk X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Engineering:/user/public-use r/Topics/Engineering X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Research:/user/public-user/T opics/Research X-BEDEWORK-CS;X-BEDEWORK-PARAM-DESCRIPTION="/principals/users/agrp_Artsand Sciences_Biology,/principals/users/agrp_PrattSchool_BME,/principals/users /agrp_ArtsandSciences_Chemistry,/principals/users/agrp_PrattSchool_CEE,/p rincipals/users/agrp_PrattSchool_ECE,/principals/users/agrp__ArtsandScien ces_Mathematics,/principals/users/agrp_PrattSchool_MEMS,/principals/users /agrp_NSOE_NicholasInstituteforEnvironmentalPolicySolutions,/principals/u sers/agrp__ArtsandSciences_Physics,/principals/users/agrp_PrattSchool,/pr incipals/users/agrp__ArtsandSciences_TrinityCollege,":Biology\,Biomedical Engineering (BME)\,Chemistry\,Civil and Environmental Engineering (CEE)\ ,Electrical and Computer Engineering (ECE)\,Mathematics\,Mechanical Engin eering and Materials Science (MEMS)\,Nicholas Institute for Energy\, Envi ronment and Sustainability\,Physics\,Pratt School of Engineering\,Trinity College X-BEDEWORK-STUDENT-CONTACT;X-BEDEWORK-PARAM-EMAIL=liana.igescu@duke.edu:Li ana Igescu X-BEDEWORK-SPEAKER:Ralph Colby X-BEDEWORK-SUBMITTEDBY:lmi3 for Duke Materials Initiative (agrp_Institutes _MaterialsScienceandEngineering) X-BEDEWORK-IMAGE-X1:0 X-BEDEWORK-IMAGE-Y1:-0.3333333333333144 X-BEDEWORK-IMAGE-X2:530 X-BEDEWORK-IMAGE-Y2:353 X-BEDEWORK-IMAGE-CROP-WIDTH:530 X-BEDEWORK-IMAGE-CROP-HEIGHT:353.3333333333333 X-BEDEWORK-IMAGE-ALT-TEXT:Ralph_Colby X-BEDEWORK-IMAGE:/public/Images/Untitled_20250904031403PM.png X-BEDEWORK-THUMB-IMAGE:/public/Images/Untitled_20250904031403PM-thumb.png END:VEVENT BEGIN:VEVENT CATEGORIES:Engineering CATEGORIES:Lectures/Conferences CATEGORIES:Other CATEGORIES:Utilities CATEGORIES:Lecture/Talk CATEGORIES:Panel/Seminar/Colloquium CATEGORIES:Conference/Symposium CATEGORIES:Meeting CATEGORIES:Main CONTACT;X-BEDEWORK-UID=8a0290b4-860465b2-0186-32feb568-0000477d:Spaulding\ , Amy CREATED:20250612T184145Z DESCRIPTION:Thomas Lord Department of Mechanical Engineering & Materials S cience (MEMS)\, Fall 2025 Speaker Series welcomes Dr. Tyler Clites\, assi stant professor of Mechanical and Aerospace Engineering at UCLA\, to give the talk\, "Anatomics: Co-engineering Body and Machine to Improve Bionic Performance."\n\nABSTRACT: Bionic systems are no longer the stuff of sci ence fiction. Exoskeletons and prostheses restore mobility to people with physical disabilities and augment able-bodied performance. Implants can eliminate pain and allow long-term restoration of function. Although a co mplete bionic system is made up of biological structures ("the body") and mechatronics ("the machine")\, the traditional development approach focu ses solely on engineering the machine. As a result\, even the most advanc ed bionic systems are subject to fundamental limitations of the human bod y. Turning this paradigm on his head\, Prof. Clites has introduced the co ncept of anatomics\, in which body and machine are developed in parallel. In this seminar\, Prof. Clites will provide examples of how his laborato ry has applied the anatomics framework to a range of clinical problems in cluding amputation\, limb salvage\, joint replacement\, and paralysis. He will show entirely novel solutions to long-standing clinical problems\, including compliant-mechanism-based orthopaedic implants\, electromagneti c attachment of external prostheses to the body\, and sensate prosthetic devices that are covered in human skin. He will also showcase the breadth of data that his team has produced in optimizing and validating these so lutions\, including theoretical analysis\, simulation\, benchtop experime nts\, cadaver testing\, animal testing\, and biomechanical experimentatio n with human subjects.\n\nBIO:TYLER CLITES is an Assistant Professor of M echanical and Aerospace Engineering at UCLA\, with joint appointments Bio engineering and the Department of Orthopaedic Surgery at UCLA's David Gef fen School of Medicine. Prof. Clites earned his Ph.D. in 2018 from the Ha rvard/MIT program in Health Sciences and Technology\, where he led the de velopment of a novel surgical procedure for limb amputation to improve ne ural interfacing and control. He then did a postdoc in Mechanical Enginee ring and Robotics at the University of Michigan. His research has been pu blished in clinical and engineering journals\, and featured at TED\, in T he New Yorker and The New York Times\, and on 60 Minutes and CNN.\n\nHost : Ken Gall DURATION:PT1H DTSTAMP:20250915T151453Z DTSTART;TZID=America/New_York:20251022T120000 LAST-MODIFIED:20250915T151453Z LOCATION;X-BEDEWORK-UID=18832e99-20476e5b-0120-58864347-000000be:Fitzpatri ck Center Schiciano Auditorium Side A\, room 1464 STATUS:CONFIRMED SUMMARY:MEMS Seminar: Tyler Clites\, "Anatomics: Co-Engineering Body and M achine to Improve Bionic Performance" UID:CAL-8a00f888-97512113-0197-6572b416-00003f4ademobedework@mysite.edu X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Main:/user/public-user/Utili ties/Main X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Lecture_Talk:/user/public-us er/Lectures_Conferences/Lecture_Talk X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Meeting:/user/public-user/Ot her/Meeting X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Engineering:/user/public-use r/Topics/Engineering X-BEDEWORK-CS;X-BEDEWORK-PARAM-DESCRIPTION="/principals/users/agrp_PrattSc hool,":Pratt School of Engineering X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Conference_Symposium:/user/p ublic-user/Lectures_Conferences/Conference_Symposium X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Panel_Seminar_Colloquium:/us er/public-user/Lectures_Conferences/Panel_Seminar_Colloquium X-BEDEWORK-DUKE-SERIES:MEMS Seminar Fall 2025 Speaker Series X-BEDEWORK-SUBMITTEDBY:acs2 for Mechanical Engineering and Materials Scien ce (MEMS) (agrp_PrattSchool_MEMS) X-BEDEWORK-SPEAKER:Tyler Clites END:VEVENT BEGIN:VEVENT CATEGORIES:Engineering CATEGORIES:Lectures/Conferences CATEGORIES:Other CATEGORIES:Utilities CATEGORIES:Lecture/Talk CATEGORIES:Panel/Seminar/Colloquium CATEGORIES:Conference/Symposium CATEGORIES:Meeting CATEGORIES:Main CONTACT;X-BEDEWORK-UID=8a0290b4-860465b2-0186-32feb568-0000477d:Spaulding\ , Amy CREATED:20250612T184353Z DESCRIPTION:Thomas Lord Department of Mechanical Engineering & Materials S cience (MEMS)\, Fall 2025 Speaker Series welcomes Dr. Ruijuan Xu\, from N orth Carolina State University\, to deliver a talk entitled\, "Manipulati ng phase transitions in lead-free ferroelectric heterostructures and memb ranes." \n\nAbstract: Complex oxides are fascinating materials that exhib it a rich spectrum of electrical\, magnetic\, optical\, and thermal prope rties. Recent advances in atomic-scale epitaxy have enabled the creation of high-quality oxide heterostructures and freestanding membranes\, openi ng new pathways to explore and manipulate emergent phase transitions and functionalities. In this presentation\, I will use sodium niobates as a m odel system to demonstrate how external stimuli such as strain\, electric fields\, and size effects can be harnessed to induce novel ferroic order s with enhanced ferroelectric and dielectric responses. I will discuss a strain-induced emergent phase boundary in sodium niobate heterostructures \, where competing structural phases yield multi-state switching and enha nced dielectric susceptibility and tunability. I will also highlight an i ntrinsic\, size-driven antiferroelectric-to-ferroelectric transition in f reestanding sodium niobate membranes.\n\nBiography: Dr. Ruijuan Xu is an Assistant Professor of Materials Science and Engineering at North Carolin a State University.
