ABSTRACT:  Globe warming and energy security are two major challenges the world is facing today. To preserve our environment and energy resource, it is imperative to maximize the utilization of existing fuels while exploring renewable sources. Fuel cell and lithium metal battery as the next-generation high-efficiency energy conversion and storage devices have attracted a great deal of attentions in recent years. This presentation summarizes some recent progresses in my laboratory in these two research areas.

ABSTRACT:  In order to reduce carbon emissions and construct sustainable society, it is very important to construct sustainable biorefineries, which produce biofuel/biochemical from biomass. Consolidated bioprocessing (CBP), which integrates enzyme production, saccharification and fermentation into a single process, is a promising strategy for effective bioproduction.

ABSTRACT:  This presentation will provide an overview of recent progress and remaining technical challenges of PEM fuel cells. The important contribution of catalyst materials and catalyst layer towards wide-spread commercialization of fuel cells will be highlighted. The advantage and possible limitations of various types of catalysts, such as Pt alloys (de-alloys), core-shell catalysts and shape-controlled nanocrystal catalysts will be assessed.
