MSE Seminar: “Future Directions in Self-Assembly for Nanopatterning”

Macromolecular self-assembly has evolved to become an important and valuable tool for bottom-up patterning and fabrication at the nanometer scale. From block copolymer lithography to nanocrystal superlattices to biomolecular assemblies, bottom-up patterning is reaching an unprecedent level of control over complex patterns at the nanoscale with an increasing degree of precision. There is no question […]

MSE Seminar: “When ions meet electrons — Modeling the interfaces in Solid-State Batteries”

With the rapid development of fast Li-ion conductors, the major bottleneck for all-solid-state Li-ion batteries lies at the high interfacial resistance and Li dendrite growth. These problems require a fundamental understanding of the interfaces, where charge transfer reactions occur and electrochemistry, physics, and solid mechanics are coupled. This talk will focus on the new mechanistic […]

MSE Seminar: “Tailoring materials properties by ultrafast laser driving of collective modes”

MSE Seminar: “Controlling ferroelectricity at the nanoscale: from oxide heterostructures to freestanding crystalline membranes”

Complex oxides are fascinating material systems exhibiting a diverse set of electrical, magnetic, and thermal properties. In particular, ferroelectric oxides with an electrically switchable polarization and large dielectric and piezoelectric responses are considered as critical components for next-generation low-power logic devices, non-volatile memories, and nanoscale sensors and actuators, etc. Recent advances in thin-film synthesis techniques […]

MSE Seminar: “Engineering nanoparticle-cell interactions: using a library-based approach to guide drug carrier design”

Nanoparticles offer huge promise as drug delivery vehicles, though their translation to the clinic is hampered due to limited accumulation at target disease sites. To overcome this hurdle, we have employed colloidal layer-by-layer assembly to generate comprehensive nanoparticle libraries to study the role of chemical composition in nanoparticle targeting, trafficking, and uptake. In this seminar, […]

MSE Seminar: “Engineering topological phases in graphene moiré heterostructures”

Taming topological electronic phases is a fundamental challenge and an important milestone on the way towards novel electronic devices and topological quantum computation. Recent advances in fabrication techniques have made van der Waals (vdW) heterostructures one of the most active platforms for the experimental investigation of topological electronic phases in 2D. Moiré superlattices, which arise […]

MSE Seminar: “Harnessing Temporally Controlled Biophysical Cues To Direct Stem Cell Phenotype”

Endogenous tissue-specific stem cells are crucial regulators of tissue health throughout life, orchestrating diverse functions ranging from learning and cognition to skeletal muscle homeostasis. The local microenvironment, or stem cell niche, presents a myriad of biochemical and biophysical factors that direct cell fate. Stem cell mediated tissue regeneration relies on presentation of these factors in […]

Inaugural Joseph Bordogna Forum: “A Call to Action for Racial Justice and Equity in Engineering”

Racism and anti-Blackness are crises that jeopardize our democracy, productivity and well-being and call into question whether we can all live together peaceably and harmoniously in a just and equitable American society. At this critical moment in our nation’s history we need more than words that renounce racism and anti-Blackness, we need actions to abolish […]

MSE Seminar: “Spirals and skyrmions in magnets and their emergent electromagnetism”

MEAM Seminar: “Modeling the Behavior of Shape Memory Alloy Structures”

I will present recent work on the modeling of the structural response of shape memory alloy tubes, bars, and beams. We have developed a new constitutive model that captures pseudoelastic transformation induced recoverable deformation in SMAs including the strong asymmetries in the tensile and compressive responses. Instead of introducing multiple conditions for forward phase transformation, […]
