Innovative Technology for Selective Contaminant Removal

Lean M.H., Chang N., Seo J., Kole A., Hsieh H.B., Melde K., PARC, US

This paper describes a two-stage water treatment technology for removal of dissolved contaminants that is relevant to many water matrices. Removal is achieved by adapting conventional adsorption, coagulation and flocculation, or lime softening and/or soda [...]

Adsorption-Enhanced Compressed Air Energy Storage

Havel T.F., Energy Compression Inc., US

Adsorption-Enhanced Compressed Air Energy Storage (AE-CAES) uses nano-porous materials to adsorb air. The use of an adsorbent changes the effective equation of state for air, so that it becomes possible to operate the system at [...]

Nanostructured TiO2 for Photovoltaic Hydrogen Production

Patel M., Imperial College London, UK

Theoretical and experimental methods are adopted in order to gain further understanding of photocatalytic water splitting over the semiconductor TiO2. Periodic density functional theory calculations are used to study the adsorption of water on the [...]

Precipitation, Adsorption and Inhibitory Effects of Nano Copper in Wastewater Activated Sludge

Smeraldi J., Rajagopalan G., Cooper W.J., Hosseini T., Rosso D., University of California Irvine, US

Objective of this study is to compare the fate, removal and inhibitory effects of nanocopper (oxide) with ionic copper in activated sludge. Impacts of functionalization (complexation) of nanocopper as well as the mechanism of nanocopper [...]

Synthesis of Sulfated and Carbon-Coated Al2O3 Aerogels and Their Activity in Dehydrochlorination of 1-Chlorobutane and (2-Chloroethyl)ethyl Sulfide

Bedilo A.F., Volodin A.M., Klabunde K.J., Boreskov Institute of Catalysis, RU

Alumina is widely used as a sorbent and catalyst support. These applications typically require high surface area, stability in the used environment and often the presence of specific groups on the surface. Many of these [...]

Silica Nanosprings – A Novel Nanostructured Material for Hydrogen Storage

Norton M.G., McIlroy D.N., Corti G., Miller M.A., Washington State University, US

Hydrogen storage for transportation applications remains a challenge. Current approaches are still short of published goals, in particular in being able to operate at acceptable temperatures. Physisorption, or non-dissociative approaches, where the hydrogen is stored [...]
