报告介绍 Biosketch:　　Liz completed an undergraduate degree in Biochemistry and Biological Chemistry at the University of Nottingham where she stayed to carry out a PhD in organic synthesis under the supervision of Professor Jim Anderson. Since then, she has worked for the RSC as an Assistant Editor for Dalton Transactions, CrystEngComm and Chemical Society Reviews, and as a Deputy Editor for the Materials ...

报告介绍 Abstract: 　　In this talk I will describe results of Hall effect measurements on several systems exhibiting magnetically driven percolative phase transitions. The talk will focus primarily on the semimetallic ferromagnet EuB6, in which we observed a distinctive switch in the Hall resistivity slope in the paramagnetic state. The switching fields in a broad temperature range were found to correspond ...

报告介绍 报告摘要： Graphene-based materials are promising because of their electronic and thermal transport, mechanical properties, high specific surface area, that they can act as an atom thick layer, barrier, or membrane, among other reasons. (Our micromechanical exfoliation approaches conceived of in 1998 yielded multilayer graphene and one paper described in detail how monolayer graphene could be o...

报告介绍 Abstract: Modern biological physics has been significantly advanced recently with rapid developments of various physical techniques and molecular biology methods. Complex biological machinery can be investigated at the most fundamental level and thus molecular mechanisms are elucidated. Here, we present our recent studies of several important biological systems by integrating femtosecond spectroscop...

报告介绍 Abstract:Controlling the shape of colloidal nanocrystals may initially seem like a scientific curiosity, but its implication goes far beyond aesthetic appeal. For nanocrystals made of noble metals, shape not only determines their chemical, plasmonic, and catalytic properties but also their relevance for electronic and photonic applications. Although the first synthesis of colloidal nanocrystals can ...

报告介绍 报告摘要：Titanium dioxide (TiO2) is one of the most widely used semiconductors in photovoltaics and photocatalysis because it is nontoxic, abundant, stable and photoactive. However, the wide bandgap, low electron mobility and short minority carrier diffusion length of TiO2 limit its quantum efficiency in these applications. In this talk, I will present a solution chemical approach for making TiO2 n...

报告介绍 报告摘要：To design materials with optimum properties and desired behavior, accurate descriptions of the underlying physics and chemistry of the materials are needed. Computer modeling combined with experiments play crucial and integrated roles, to provide detailed insight into structure, capture the structure-property-performance relationships, advance the understanding of experimental observations...

报告介绍 报告摘要： Computer simulations are used to study the unusual structure and dynamics of liquid/solid water at molecular scale. As an introduction, I calculate prototype water structures on metal surface. This study is further extended to silica surface, where a two-dimensional tessellation ice is observed. The new configuration is stable up to room temperature, because all the water molecu...

报告介绍 Personal statement:　　My research interest lies in quantum correlated physics in novel materials, such as oxide interfaces, topological insulators and superconductors, high temperature superconductors, and frustrated magnets. We develop innovative experimental tools to explore crucial signatures of novel phenomena in new materials. As a Ph.D. student at Princeton University, I invented a new techni...

The fascinating nonlinear (quantum) dynamics of the coupled electron-nuclear spin system is universal in quantum dot optics and transport. In the first part of this ta...

报告介绍 报告摘要： A powerful approach for investigating properties of matter is light scattering. In this talk, I will discuss how light scattering is used to probe collective modes of electrons in two distinct systems. The first example focuses on light scattering from collective electron oscillations in metals called plasmons. We have recently proposed and demonstrated a novel three-dimensional orientati...

For architectural acoustics, the sound field modeling in long spaces is formulated using 1-D transport equations. Experiments obtained from a long room scale model are used to verify the transport equation models. In addition to...
