SUMMARY:MEAM Seminar: "Architected Nanoscale Plates for Thermionic Energy Conversion and Relativistic Interstellar Travel"
DESCRIPTION:Architected plates feature geometrical patterns that provide advantageous mechanical properties\, such as an enhanced bending stiffness or a reduced tendency to tear. In this talk I will introduce our research group’s multiscale hexagonally patterned corrugated plates\, which have nano-scale film thicknesses\, micron-scale total heights\, and square-centimeter-scale lateral area dimensions. I will first explain how we use these plates in direct thermionic heat-to-electricity generators and show that new corrugation modalities provide several-fold reductions in the plates’ thermal conductivity\, leading to greater device efficiency. I will then show that our plates can be tailored to become ultra-reflective membranes for photon-propelled space travel near the speed of light\, and explain mechanical guidelines for the design of relativistic light sails.

SUMMARY:ESE Fall Colloquium - "Processing in Memory: Past\, Present\, and Future"
DESCRIPTION:Applications are increasingly data-intensive and bound by the performance of the memory and/or storage system. This “memory wall” arises from several factors: the volume of data is increasing exponentially\, outstripping cache capacities; many applications extensively use streaming data with little or no temporal reuse; as algorithms become more sophisticated\, access patterns are often unfriendly to effective caching; and the computation intensity of many of these algorithms is low–we often spend more time and energy moving data to the processor than we spend computing on the data.  All these factors motivate breaking down the classic von Neumann architecture that separates processing and memory\, and computing as close to the data as possible\, with processing elements either tightly coupled with memory or storage\, or possibly even embedded directly in the memory chips.  \n The memory wall has been a concern for decades\, with numerous proposals over the years for processing-in-memory and near-data architectures.  This talk will review the motivation for processing in memory and some prior proposals\, then provide an overview of the current landscape\, take a deep dive into the Fulcrum processing-in-memory architecture developed by my research group\, and then conclude with some suggestions for promising applications and directions for in-memory/near-data design\, together with some necessary operating-system and middleware capabilities.

SUMMARY:CBE PhD Dissertation Defense | "Selective Catalytic Reactions for Taking Furan-Based Compounds to Useful Chemicals"
DESCRIPTION:Abstract: \n“Efforts have been devoted to understanding the upgrading of plant-based biomass waste into useful chemicals to replace the current petrochemical production. An extensive amount of work has been accomplished in the past few decades but there are still many uncertainties. The transformation of furanic compounds\, which present a major fraction in lignocellulosic biomass\, is one of them. Furans are important solvent molecules in industry\, and they are also critical feedstock to produce other valuable chemicals. The work in this presentation mainly focused on bridging the gap between different chemistry for a complete industrial production process. Two reactions that I have extensively studied were the acylation of furans and the dehydra-decyclization of cyclic ethers to corresponding conjugated dienes.\nSelective Friedel-Crafts acylation of furans to a type of alkyl furan ketone molecules is very useful for increasing the molecular weight of biomass in a controlled manner\, and product from this reaction can be applied in many fields. The acylation reaction was classically performed with acid anhydride or chloride\, using strong Lewis acids as catalysts (such as AlCl3) through homogeneous reactions. To enhance the reaction efficiency and reduce separation cost\, I used non-branched long-chain carboxylic acids as acylation agent and Brønsted acidic zeolites as catalyst. With proper reaction conditions demonstrated for the direct acylation reaction\, solvent was found to play an important role during reaction\, which can be utilized for further reaction performance improvement. \nThe second reaction is to produce conjugated dienes from cyclic ethers\, which has been studied over various Brønsted zeolitic materials. Conjugated dienes are the backbone monomers in synthetic rubber production. Previous works on zeolites have either low selectivity to the desired conjugated diene products or low reaction rates\, and having protons as active sites\, oligomerization of unsaturated hydrocarbons on the Brønsted catalysts was another big issue. In my work\, ZrO2 was identified to be a promising catalyst to produce C4~C5 conjugated dienes from corresponding cyclic ethers at quantitative conversion. ZrO2 has shown a significant performance compared to other common-seen Lewis acids\, and a possible reaction mechanism on ZrO2 was tabulated for further catalyst design.”

SUMMARY:Fall 2021 GRASP Seminar: Heng Yang\, "Certifiable Outlier-Robust Geometric Perception: Robots that See through the Clutter with Confidence"
DESCRIPTION:*This will be a HYBRID Event with in-person attendance for Dr. Malikopoulos’ in-person talk in Wu & Chen Auditorium and Virtual attendance via Zoom Webinar here.  \nGeometric perception is the task of estimating geometric models (e.g.\, object pose and 3D structure) from sensor measurements and priors (e.g.\, point clouds and neural network detections). Geometric perception is a fundamental building block for robotics applications ranging from intelligent transportation to space autonomy. The ubiquitous existence of outliers —measurements that tell no or little information about the models to be estimated— makes it theoretically intractable to perform estimation with guaranteed optimality. Despite this theoretical intractability\, safety-critical robotics applications still demand trustworthiness and performance guarantees on perception algorithms. In this talk\, I present certifiable outlier-robust geometric perception\, a new paradigm to design tractable algorithms that enjoy rigorous performance guarantees\, i.e.\, they return an optimal estimate with a certificate of optimality for a majority of problem instances\, but declare failure and provide a measure of suboptimality for worst-case instances. Particularly\, I present two general-purpose algorithms in the certifiable perception toolbox: (i) an estimator that uses graph theory to prune gross outliers and leverages graduated non-convexity to compute the optimal model estimate with high probability of success\, and (ii) a certifier that employs sparse semidefinite programming (SDP) relaxation and a novel SDP solver to endow the estimator with an optimality certificate or escape local minima otherwise. The estimator is fast and robust against up to 99% random outliers in practical perception applications\, and the certifier can compute high-accuracy optimality certificates for large-scale problems beyond the reach of existing SDP solvers. I showcase certifiable outlier-robust perception on robotics applications such as scan matching\, satellite pose estimation\, and vehicle pose and shape estimation. I conclude by remarking opportunities for integrating certifiable perception with big data\, machine learning\, and safe control towards trustworthy autonomy.

SUMMARY:ESE Fall Colloquium - "Harnessing Piezoelectricity in Novel Microsystems for Classical and Quantum Information Processing"
DESCRIPTION:Piezoelectricity is the intrinsic coupling between electric fields and strains in materials. While piezoelectric sensors\, actuators\, and RF filters are ubiquitous and important components of existing microsystems\, their potential is still largely underutilized in many application spaces. In this talk\, I will discuss the physics\, engineering\, and applications of two novel classes of piezoelectrically enabled microsystems developed by the MEMS-Enabled Quantum Photonics group at Sandia National Labs: (1) piezoelectrically modulated photonic\, phononic\, and optomechanical integrated circuits and 2) piezoelectric-semiconductor hybrids for all-acoustic radio frequency signal processing and acoustoelectrically enhanced optomechanics. I will discuss these systems in detail and show how they are being used to make significant advances in both classical and quantum information processing applications.

SUMMARY:BE Seminar: "Neural Engineering and the Primate Brain: Working at the Electrical and Optical Interface" (Bijan Pesaran)
DESCRIPTION:This seminar will be held live and broadcast on zoom – link coming soon. \nNeural engineering is enjoying an era of transformative growth. Classical methods that dominated the neurosciences for decades are being replaced by powerful new technologies. In this talk\, I will discuss how to engineer electrical and optical interfaces to the primate brain. I will first present work on electrode interfaces that stimulate and record at the surface of and within the brain. I will show how simultaneously measuring and manipulating neurons immediately beneath electrode contacts during behavior delivers ground-truth data.  The results have implications for electrode interface design and new generations of implantable biomedical devices. I will then turn to optical neural interfaces. Two-photon fluorescence microscopy images the activity of neurons expressing genetically-encoded calcium indicators and is most often performed in small animal models\, such as the mouse\, worm and fly. I will present a cellular-resolution robotic imaging platform to investigate the non-human primate brain at scale. I will finish by discussing potential applications of this technology to a range of scientific and clinical goals.
