报告介绍 Proton exchange membrane fuel cells (PEMFCs) are efficient energy converting devices and have great potentials in alternative energy applications. Nanoscale materials have been extensive applied in fuel cell technologies. For example, to increase the surface area of the catalysts so to maximize the power output, fuel cell catalysts are fabricated in the nanoparticle form. A long time puzzle is wheth...

报告介绍 BBC news: “…you know that we love robots…Spider robots…The BBC has just reported on such research from Columbia University by Dr. Milan Stojanovic, a professor of biochemistry. Dr. Stojanovic and his team have built what they call a "molecular spider" that has four legs, each of which are made up of 10nm strands of DNA…But Dr. Stojanovic isn't stopping the...

报告介绍 Bioorthogonal chemistry offers a powerful tool to study protein structure, dynamics, and function in living systems. Recently, we have developed a photoinducible, nitrle imine mediated 1,3-diplor cycloaddition as a bioorthogonal reaction, and demonstrated its utility in selective protein labeling both in vitro and in vivo. In this talk, the scope of this reaction as well as the applications of this ...

报告介绍 The talk will provide a development of materials science, including nanotechnology, energy materials, biomaterials, polymers and organic electronics. Also, the talk will tell us how to maximize our success.

报告介绍 Spontaneous formation of ordered structures from amphiphilic molecules has attracted tremendous attentions in the last decades. Understanding the structures and phase transitions in block copolymers has been one of the most active research areas in polymer science in the past two decades. One of the achievements from these efforts is the self-consistent field theory (SCFT), which provides a powerful...
