MSE Seminar: “In-Situ Resistance Degradation & Switching of Bulk Fe-doped SrTiO3 and Yttria-Stabilized Zirconia”

Perovskite-type titanates are the standard dielectric used in multilayer ceramic capacitors (MLCCs), and yttria-stabilized (YSZ) is the prototypical fast oxygen conductor used in solid oxide fuel cells (SOFCs) and oxygen sensors. Under a DC electric field, the resistance of YSZ and Fe-doped strontium titanate (Fe-STO) degrades in an indistinguishable way. This is surprising because, unlike […]

MEAM Seminar: “Micro/Nanomanufacturing of 3D Functional Coatings via Self-Limiting Electrospray Deposition”

Recent developments in nanostructured materials have demonstrated myriad desirable properties ranging from optical and mechanical metamaterials to biomanipulative surfaces. To bring these properties from the lab to the commercial space will require innovative nanomanufacturing strategies focused on scalable and cost-effective techniques. My lab, the Hybrid Micro/Nanomanufacturing Laboratory, applies the manipulation of fundamental driving forces to […]

MSE Seminar: “Exploring Photonic Materials with Symmetry and Topology”

Symmetry and topology are fundamental notions existing in all kinds of natural systems, from spiral galaxies and hurricanes to amino acids in molecules and non-trivial topologically protected electronic states in condensed matter. A stream of photons is typically topologically trivial, nevertheless, its full-vector nature intrinsically endows light with full capability of creating and carrying unique […]

MSE Seminar: “How Do You Make a Micro-Robot?”

MSE Seminar: “Why Industrial Research Is Critical: A Brief History in the 20th and 21st Centuries”

MSE Seminar: “Managing Intercultural Interactions in a Challenging Global Higher Education Landscape”

The rapidly diversifying face of colleges and universities in the United States including the University of Pennsylvania require that we are able to manage intercultural relationships from different backgrounds. We are all working in a multicultural institution, with students, faculty and staff from all over the world. This makes for a very diverse, vibrant community […]

MSE Seminar: “Scalable Multifunctional Nanoarchitectures for Energy Storage”

MSE Seminar: “Science and Applications of Topological Photonics across the Electromagnetic Spectrum”

The 2016 Nobel Prize in Physics was awarded to Kosterlitz, Thouless, and Haldane for their pioneering theoretical work on the novel and counter-intuitive phases of matter that are now referred to as topological phases. Almost half a century after these researchers applied powerful mathematical techniques of topology to condensed matter systems, a new rapidly developing […]

MSE Special Seminar: “What They Don’t Teach You in School that You Need to Succeed in Life”

MSE Seminar: “A Polymer Brush Approach to Controlling Biological Binding to Surfaces”

Polymer brushes are a common feature in many biological surfaces. The ability to rapidly transform a substrate from a hard, structural material to a soft, hydrogel structure over the course of a few tens of nanometers makes polymer brushes elegant materials for tailoring the biology-materials interface. Polymer brushes, because of their surface confinement, are typically […]
