MSE Seminar: “Microstructural Design Principles for Achieving Stable Electrochemical Interfaces for Metal Anodes”

Lithium metal battery systems (LMBs) are being sought as an ultimate replacement to LIBs, potentially increasing the cell energy by over fifty percent due to the high capacity and low voltage of the metal anode. Analogous improvement in energy is possible with sodium metal batteries (NMBs) and with potassium metal batteries (KMBs), where existing ion […]

MSE Seminar: “Topological Quantum Phases, Novel Superconductors, and Ultra-Thin Films Beyond Graphene”

Dr. Bansil will discuss some of his recent work aimed at understanding the electronic structure and spectroscopy of novel superconductors, topological materials, and atomically thin 2D films and battery materials. [1-5] Illustrative examples will include: (i) How by exploiting electronic structure techniques we have been able to successfully predict and understand the characteristics of many […]

MSE Seminar: “Data-driven materials design in the quantum regime: motif-centric learning framework and local-symmetry-guided material discovery”

Materials design in the quantum regime call for the integration of multi-tier materials information that go beyond atomic structures. Especially, many quantum behaviors are greatly controlled by local symmetries and local bonding environments. In this talk, motivated by Pauling’s rules, Dr. Yan will show that local bonding environments (motifs) can be incorporated in a graph-based […]

MSE Thesis Defense: “Ultra-High-Resolution Patterning and Pattern Transfer via Nanocrystal Colloidal Lithography”

The ability to design, pattern, and process materials at the nanoscale has enabled vast research opportunities ranging from fundamental science to technological applications and device integration. The continued development of nanoscience and nanotechnology relies upon pushing the limits of nanoscale fabrication capabilities. After decades of development, this frontier has moved to the sub-10 nm length […]

MSE Seminar: “Local to Meso-scale Order in Electronic Ceramics Characterized by Aberration -Corrected Scanning Transmission Electron Microscopy”

The ability to design the composition and microstructure of electronic ceramics for emerging technological applications requires sophisticated characterization techniques that can provide quantitative information about local structure and chemistry. Such structure quantification is particularly important to the fundamental understanding of properties in many important non-linear dielectrics, where chemical heterogeneities associated with dopants or intrinsic lattice […]

MSE Seminar: “Lansdcapes of Glass”

If cooled sufficiently quickly, the disorder of a liquid can be “quenched” or locked in place; the resulting amorphous solid is glass. Although it appears to be solid on human timescales, glass continues to creep due to thermal vibrations at the molecular scale. Consider now a pile of sand; it too is a disordered system, […]

MSE Grace Hopper Lecture: “Optics on the Nanoscale: Conquering Absorption with Nonlinear Optics”

Optical nanostructures enable molding the flow of light on the subwavelength scale rendering possible the realization of compact, cost-effective, flat and highly efficient optical components for imaging, spectroscopy, sensing, and communications. From the fundamental science viewpoint, light-matter interactions at the nanoscale reveal themselves in new and often unexpected ways. In fact, the usual linear and […]

MSE Seminar: “Topological Physics: from Photons to Electrons”

There are many intriguing physical phenomena that are associated with topological features — global properties that are not discernible locally. The best-known examples are quantum Hall effects in electronic systems, where insensitivity to local properties manifests itself as conductance through edge states which are insensitive to defects and disorder. In this talk, Dr. Hafezi will […]

MSE Seminar: “Metals and Alloys: A Critical Weapon in the Fight against Climate Change”

Today in the U.S., we deal with the severe, wide ranging effects of climate change from the West to East Coast in the form of heat waves, drought, wildfires, and flooding. To end these disasters, we need to drastically change the way we produce and use energy. For example, in 2020, over 72 % of […]
