Talk Title: How to Make Carbon Capture Smarter: A Deep Dive Into Materials Chemistry for Integrated Carbon Capture and Utilization
Series: Mork Family Department Distinguished Lecture Series
Abstract: The conventional carbon capture and utilization (CCU) process involves separating CO2 from waste streams,transporting it through a pipeline, and then converting it into fuels and chemical commodities. On the other hand,Integrated Carbon Capture and Utilization (ICCU) or thermocatalytic reactive capture offers a more efficient approachwith lower energy requirements. This method directly transforms captured CO2 into methanol, synthesis gas, andcarbon monoxide.
At the heart of an ICCU scheme are dual-functional materials comprised of a catalyst affixed to a solid sorbent,enabling the selective capture and conversion of CO2 within the same reactor. This seminar will delve into efforts toenhance these materials, beginning with the example of Zr-modified Ni/CaO DFMs, which exhibit improved CO2 capture and conversion capabilities. Additionally, there will be a discussion on multifunctional materials such as self-regenerative Ni-doped CaTiO3/CaO nanocomposites, explored for CO2 capture and subsequent dry reforming of methane (ICCDRM). These materials have demonstrated stable CO2 capture capacity and syngas productivity overmultiple cycles, with reduced coke deposition due to small exsolved Ni nanoparticles and their strong interaction withthe host material.

ECE Seminar: From Single-agent to Federated Reinforcement Learning

Speaker: Dr. Yuejie Chi, Sense of Wonder Group Endowed Professor of Electrical and Computer Engineering in AI Systems, Carnegie Mellon University
Talk Title: From Single-agent to Federated Reinforcement Learning
Abstract: Reinforcement learning (RL) has garnered significant interest in recent years due to its success in a wide variety of modern applications. Q-learning, which seeks to learn the optimal Q-function of a Markov decision process (MDP) in a model-free fashion, lies at the heart of RL practices. However, theoretical understandings on its non-asymptotic sample complexity remain unsatisfactory, despite significant recent efforts. In this talk, we first show a tight sample complexity bound of Q-learning in the single-agent setting, together with a matching lower bound to establish its minimax sub-optimality. We then show how federated versions of Q-learning allow collaborative learning using data collected by multiple agents without central sharing, where an importance averaging scheme is introduced to unveil the blessing of heterogeneity.
Biography: Dr. Yuejie Chi is the Sense of Wonder Group Endowed Professor of Electrical and Computer Engineering in AI Systems at Carnegie Mellon University, with courtesy appointments in the Machine Learning department and CyLab. She received her Ph.D. and M.A. from Princeton University, and B. Eng. (Hon.) from Tsinghua University, all in Electrical Engineering. Her research interests lie in the theoretical and algorithmic foundations of data science, signal processing, machine learning and inverse problems, with applications in sensing, imaging, decision making, and generative AI. Among others, Dr. Chi is a recipient of the Presidential Early Career Award for Scientists and Engineers (PECASE), NSF CAREER Award, ONR YIP Award, AFOSR YIP Award, the inaugural IEEE Signal Processing Society Early Career Technical Achievement Award for contributions to high-dimensional structured signal processing, and multiple paper awards including the SIAM Activity Group on Imaging Science Best Paper Prize and IEEE Signal Processing Society Young Author Best Paper Award. She is an IEEE Fellow (Class of 2023) for contributions to statistical signal processing with low-dimensional structures.

Talk Title: Modeling drag and heat transfer on riblets and roughness
Abstract: Riblets are a surface texture that reduce skin-friction drag in turbulent flow, and can now be found on in-service aircraft. Riblet features are smaller than the smallest vortices of turbulence. On the fuselage of a passenger aircraft, riblet spacing is about 100 microns. Riblet performance is notoriously sensitive to the fine details of their micro-structure, with optimal performance thought to require sharp tips, which are impossible to manufacture and maintain in practice. Thus, their successful application requires careful lifetime management of performance benefits, balanced against manufacturing, installation and maintenance costs. Key to this balancing act is our ability to accurately predict riblet performance given the inevitable micro-structure imperfections. To this end, I will discuss our group’s flow-physical modeling of the interaction between detailed riblet shapes and the near-wall vortices of turbulence; the outcome is a consistent improvement in accuracy of performance predictions across diverse riblet shapes.
Predicting rough-wall heat transfer has been a longstanding challenge, especially when new surface topographies are encountered. The heat-transfer coefficient of accreted ice on aircraft is different from that of engineered heat-exchanger surface textures. The best we can do are empirical correlations, which are not reliable. It is widely known that rough-wall heat transfer is not analogous to skin friction, i.e. not Reynolds analogy, but, then, what is it? With access now to the detailed temperature and flow fields near roughness features, I will show that heat transfer peaks at regions of the surface that are exposed to the oncoming flow, and, at these regions, a local version of Reynolds analogy survives. These insights allow us to develop a simple physics-based model of heat transfer that accounts for topography and working-fluid variations.
Biography: Daniel is an associate professor in the Department of Mechanical Engineering at the University of Melbourne. He obtained his bachelor's degree in engineering and computer science from the University of Melbourne in 2003, and his PhD in aeronautics from Caltech in 2009. He was a postdoc at the Jet Propulsion Laboratory before joining the University of Melbourne in 2012. Daniel's research is in computational fluid mechanics, where he tries to distil turbulent flows into simplified problems and to build physics-based models for prediction. Recently, he has been interested in turbulent flow and thermal convection over rough surfaces, riblets and sea waves, including control. Daniel is currently on a sabbatical at USC until the end of November, hosted by Prof Mitul Luhar, and is keen to explore collaborations.

Alfred E.Mann Department of Biomedical Engineering - Seminar series
Fri, Sep 06, 2024 @ 11:00 AM - 12:00 PM
Alfred E. Mann Department of Biomedical Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Dennis Discher, Ph.D., Robert D. Bent Professor, and Director, Physical Sciences Oncology Center/Project University of Pennsylvania, Philadelphia, PA
Talk Title: From Anti-Tumor Macrophages to Nuclear Mechanobiology
Abstract: Acquired immunity against tumors can in principle exploit the genetic differences that always drive cancers. Myeloid-type innate immune cells typically initiate immunity, but the cohesiveness and microenvironment of solid tumors tends to oppose such functions. We engineer tumoricidal macrophages that engulf cancer cells to initiate acquired immunity, and have discovered a cooperative mechanism for overcoming tumor cohesion. Nucleus mechanosensing has a role in model systems and helps clarify a broader landscape mechano-regulation that extends to trends for mutations across different liquid and solid tumors.
Biography: The Discher lab at Penn has contributed across cell and molecular bioengineering, biophysics, and materials biology. The lab discovered matrix elasticity effects on stem cell differentiation (Cell 2006) and nucleus mechanosensing (Science 2013). Recent efforts have focused on the mechanbiology of genetic changes in cancer and engineering of macrophages against solid tumors (Nat BME 2023). The latter followed molecular studies of ‘foreign’ versus ‘self’ recognition (Science 2013) and were motivated by delivery studies of block copolymer nano-assemblies (Science 2002). Discher is an elected member of the US National Academy of Medicine, the US National Academy of Engineering, and the American Association for the Advancement of Science, and he serves on Editorial Boards of Science, Molecular Biology of the Cell, and PNAS Nexus, among other journals.
