Electro-Chemo-Mechanics in Solid-State Batteries

Abstract: The future of e-mobility, including electric vehicles, aircraft, ships, depends on the innovation of battery technology today. Since the energy density of conventional lithium (Li)-ion battery cells with graphite and metal oxides electrodes is limited to about 300 Wh/kg at the cell level, “next-generation batteries” such as the Li-metal all-solid-state batteries (Li-ASSBs) are demanded. […]

Mechanics of Redox Active Materials

Abstract: This talk focuses on the interplay of mechanics with chemical reactions across multiple scales in redox active materials. I will use battery materials to introduce how electrochemistry induces deformation, stresses, and mechanical damage, and how mechanical stresses regulate charge transfer, mass diffusion, capacity, and voltage. I will introduce the customized operando nanoindentation and its […]

High resolution nanoparticle size determination by vapor condensation and the verification of classical heterogeneous nucleation theory

Abstract: The phenomenon of heterogeneous nucleation in the gas phase is briefly introduced, as well as a related instruments referred to as a condensation particle counter (CPCs). CPCs are widely used to detect single nanometer particles and molecular ions, by growing them into visible sizes. We review prior use of sheathed CPCs, where nanoparticles are […]

From Many-Body Quantum Systems to Classical Fluids: Quantum- Ready and Quantum-Inspired CFD

Abstract: Within the past decade, significant progress has been made in using quantum computing (QC)  for solving classical problems. In this talk, an overview is made of the ways by which QC has shown promise for fluid dynamics and combustion research. This is via both quantum-ready and quantum-inspired algorithms. The former deals with problems that […]

Functionality through multistability: from soft robots to deployable structures

Abstract: Inflating a rubber balloon leads to a dramatic shape change: a property that is exploited in the design of soft robots and deployable structures. On the one hand, fluid-driven actuators capable of complex motion can power highly adaptive and inherently safe soft robots. On the other hand, inflation can be used to transform seemingly […]

Growth and morphogenesis of confined bodies

Abstract: Natural phenomena, such as growth, instability, and failure, can be highly dependent upon activation of stochastic mechanisms at the microscale, such as the existence of microscopic imperfections, the action of molecular motors, and the diffusion of constituents. Yet, at the macroscale, astonishing order is often observed. In this talk, I will discuss our recent […]

Dynamics of Flow Past Shark-Inspired Textured Surfaces

Abstract: Skin of fast swimming shark species such as Mako are packed with overlapping micro-scale denticles where each denticle is covered with 3-7 ribs. These textures allow sharks to swim faster than other animals in the ocean. Inspired by this capability, two-dimensional symmetric and periodic textures have been considered for the purpose of drag control […]

Dielectric elastomer artificial muscles – bridging the gap to applications

Abstract: Soft robotics aims to develop technological tools to allow people to interact more closely with machines, in a range of settings, from manufacturing, to healthcare, and even our homes. Dielectric elastomer actuators (DEAs) are compliant capacitors which can directly convert an electrical input into mechanical work. DEAs hold the promise of muscle-like behavior, as […]
