报告介绍 Abstract： 　　Carbon materials are of immense practical importance, but are often known as structurally ill-defined “black stuff” such as soot. Graphenes and graphene nanoribbons (GNRs), their geometrically restricted cutouts, are new additions to the carbon family which are widely praised as multifunctional wonder materials and rich playgrounds for physicists. Indeed, graphenes hold en...

报告介绍 报告摘要： 贵金属催化剂具有很高的催化活性，是电化学能量转换与储能过程的核心材料，但高昂的成本限制了其在产业化中的广泛应用。基于纳米结构碳和过渡金属氧化物的非金属和非贵金属电催化剂在能源转化过程中具有与贵金属类似的催化活性。通过对纳米结构碳基电催化剂的杂原子掺杂可以进一步提高其在电化学氧还原反应（ORR）、产氧反应（OER）和产氢反应（HER）中的催化活性。在我们的研究中，将石墨烯/多孔碳复合材料进行非贵金属...

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...
