ABSTRACT:  Complexes formed in systems containing both positive and negative charges are of fundamental importance in a variety of materials applications.  A common method for producing polyelectrolyte complex films is to sequentially deposit oppositely charged polymers, an effective but tedious process that is not readily scalable.  A focus on this talk is on the deposition of relatively thick films directly onto conducting surfaces, using electrochemical processes to modulate the local pH.  The process is carried out on a quartz crystal microbalance, which in addition to

ABSTRACT:  The Singapore University of Technology and Design facilitated an ambitious large-scale science experiment in September and November 2015 which saw over 43,000 students carrying sensors designed to measure temperature, humidity, pressure, light, noise, IR temperature, motion, among other physical parameters in a project supported by the National Research Foundation and carried out with partners from the Ministry of Education and the Singapore Science Center.

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.

ABSTRACT:  Mathematical programming methods have been widely adopted for process design and operation, as they provide systematic means to find optimal or feasible design/operation decisions that may not be easily seen from qualitative or simple quantitative analysis. However, mathematical programming formulations of process design and operation problems are usually nonconvex, implying that an optimal, or even a feasible solution, is difficult to obtain.

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.
