Aerobic Fermenter Scale-up: Why Equal Mass Transfer Scale-up Doesn't Always Work

Nov 9, 2009

Julian B. Fasano

Transferring oxygen to the liquid is only one of several steps that must occur in an aerobic fermentation. After the oxygen is transferred to the liquid, the liquid must be thoroughly mixed throughout the vessel. Then the oxygen must diffuse through the cell wall before finally being metabolized...

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...

Catalytic Deoxygenation of Free Fatty Acids Over Pd/C

Nov 8, 2009

Jeremy Immer

Introduction Environmental concerns and dwindling world petroleum reserves have generated great interest in producing transportation fuels from bio-renewable resources. In this work, we investigate catalytic deoxygenation of free fatty acids (FFAs) [1] to produce linear hydrocarbons for second-...

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,...

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...
