Thermochemical water splitting presents a way to store thermal energy in the chemical bonds of a H 2 molecule. Besides becoming an increasingly important energy carrier, hydrogen already has vast importance in petroleum upgrading and ammonia synthesis. In an effort to improve the Sulfur-Iodine...

Simulation Study of Different Alternatives for Isoamyl Butyrate Production by Using Aspen Plus ® Jairo Duran, Karen Cañón, Iván Gil, Gerardo Rodríguez, Julio Vargas Grupo de Procesos Químicos y Bioquímicos. Department of Chemical and Environmental Engineering. Universidad Nacional de Colombia...

Introduction The production of transportation fuels from biomass, and the use of biomass as a means of carbon dioxide capture and sequestration have been identified as a strategy with potential to address the energy and environmental concerns, including fuel independence, energy availability and...

The effect of solid and gas phase heat recovery on total energy required for an ideal solar-driven carbon dioxide capture cycle based on calcium carbonate/calcium oxide calcination/carbonation is studied. The effect of varying the carbonation and calcination reaction temperatures on total energy...

Deepwater Regulations in the Gulf of Mexico The Deepwater Horizon incident (DWH) of April 2010 led to many changes in deepwater operations in the Gulf of Mexico. Not the least of those changes were to do with regulations. In the three months following DWH two important changes to the regulatory...

Micrometer-sized cylinders at fluid interfaces self-assemble owing to capillary interactions, forming linear chains of particles joined end-to-end by ‘capillary bonds’. We measure the strength of these capillary bonds by a new experimental technique. We incorporate a magnetic cylinder within a self...

Market demand is increasing rapidly for biotherapeutics such as recombinant proteins, monoclonal antibodies, viral vaccines and plasmid DNA. With the advent of molecular biotechnology and engineered cell lines, upstream production processes have made unprecedented progress in the last decade,...

The aim of the present study was to demonstrate the preparation and characterization of planar biomimetic bacterial water-channel protein Aquaporin Z (AQPZ)-incorporated polymer membranes on porous solid substrates by vesicle spreading for water treatment. AQPZ -incorporated polymer vesicles were...
