Gas Sorption in Ionic Liquid-Carbon Nanotube Composite Materials

Nov 8, 2010

Wei Shi

Molecular dynamics and Monte Carlo simulations were used to study the ionic liquid 1-n-Hexyl-3-methylimidazolium bis(Trifluoromethylsulfonyl)amide ([hmim][Tf2N]) confined into the (20,20) and (9,9) carbon nanotubes and gases (CO2, H2) absorption into the composite material consisting of the ionic...

*Corresponding author, Email: chencts@nus.edu.sg , Fax: (65)-6779 1936 ABSTRACT Freshwater shortage has caused serious world-wide problems and many technologies have been developed for water recycle and seawater desalination. Forward osmosis (FO) as a promising technology has attracted much...

Titania Nanotube Supported Gold Photoanodes

Nov 8, 2009

Peter Aurora

Photoelectrochemical cells (PEC) combine a photovoltaic device for light harvesting and an electrolyzer for water splitting into a single system. These cells consist of a photoanode for water oxidation and oxygen evolution, a cathode where hydrogen is evolved, and an electrolyte. A major obstacle...

Solar Hydrogen Production Using Ferrite-Based Water Splitting Cycles On Al2O3 Substrates

Nov 8, 2009

Jonathan Scheffe

We are reporting the results of an alternative ferrite cycle in which the ferrite (CoFe2O4) is deposited on a porous Al2O3 support via atomic layer deposition (ALD). Rather than a traditional cycle, in which the ferrite is deposited on an inert support or is unsupported, the ferrite reacts with...

Synthesis and Characterization of New Bimetallic Spinel Oxy-Nitride Photocatalysts

Nov 8, 2009

Bharat Boppana

Photocatalysis is the acceleration of a slow reaction by a photon-assisted process with titanium dioxide (TiO2) being the material of choice for most environmental applications including hydrogen production by water splitting [1,3]. Inspite of a number of advantages like optimum band structure,...

Design and Process Control Issues In Nanomanufacturing

Nov 17, 2008

Babatunde A Ogunnaike

This presentation will raise awareness of some key process issues involved in answering the following primary question: in manufacturing products designed for specific end-use applications (e.g. polymer nano-composites); or in the production of self-assembled nanomaterials with desirable structural...
