报告介绍 报告摘要： There is huge effort in searching for high-performance thermoelectric (TE) materials in recent years. For that, understanding the thermal and electrical transports in complex materials is the key scientific issues to be pursued. This talk will try to summarize our efforts in understanding thermoelectric transports in compound materials with different level of structural complexity. The co...

报告介绍 Abstract： Surface forces are conventionally interpreted under constant charge or constant potential conditions. But constant potential is a special case involving charge transfer between solution and surface. Other charging mechanisms include charge regulation, competitive site binding, and redox charging of electrodes. In each case the forces are influenced by the nonelectrosta...

报告介绍 Abstract： A ultrafine aluminum hydroxide nanoparticle suspension was prepared via controlled titration of [Al(H2O)6]3+ with L-arginine to pH 4.6. The prepared material, predominantly 10-30 nm in diameter, was purified by GPC technique and subsequently identified as gibbsite (or hydrargillite) polymorph via FTIR, powder XRD, and elemental analysis. Chemical environment and morphology were probed usi...

报告介绍 Abstract： 　　In situ scanning tunneling microscopy (STM) is considered as the most direct means to probe the static structures and dynamic reaction at electrified interfaces. This technique has been used to study the conformation of conducting polymers of aniline and pyrrole, effect of organic additive on electrodeposition of copper, the electrocatalysis of artificial metal adlayer. Some results i...

报告介绍 报告摘要： Plasmonic biochips typically consist of metallic gold or silver nanostructures on substrates through which they exhibit highly sensitive collective electromagnetic oscillations depending on the surrounding dielectric materials. These biochips are known as localized surface plasmon resonance (LSPR) sensors . From a diagnostics perspective, plasmonic-enabled methodologies for routine use an...

He held a post-doc (2004 to 2008) and a scientist position (2009) at the Lawrence Berkeley National Laboratory, working on the ultrafast dynamics of correlated electron solids and complex materials.From 2009 to 2012, he worked a...

报告介绍  Abstract：Thin films of thermochromic vanadium dioxide were deposited using a novel electric field assisted chemical vapor deposition methodology at atmospheric pressure onto glass substrates. Electric fields were generated during the deposition reaction by applying a potential difference across the inter-digitated electrodes of the gas sensor substrate or buy applying an electric field betwee...

报告介绍 Abstract： A secure and sustainable energy future that is not based on a fossil fuel based infrastructure requires the design of new materials for efficient energy conversion, transport, and storage. Indeed, materials development is a rate limiting step in many potential new energy conversion strategies, impacting the efficiency of photovoltaic solar cells, the storage capacity and power density of ...

报告介绍 报告摘要： With the advent of quantum gas microscopy of ultracold atoms in optical lattices, it is possible to detect and control all degrees of freedom of each particle comprising a many-body system. The emerging, strongly correlated quantum phases, which may be engineered with single-particle control, are characterized by large-scale entanglement between all constituents.In this talk I will presen...

报告介绍 Abstract: The first part of my talk will focus on work completed during my first round of postdoctoral training at UT southwestern Medical Center aimed at the development of a universal new imaging method to detect various types of cancers. The sensitivity of the most current cancer imaging methods is limited by over-expression of cancer biomarkers, such as the Her2/neu receptor and the folate recep...
