Photocatalytic Activity of TiO2 and TiO2-xCxNy Thin Films From Polymer Assisted Deposition

Nov 9, 2010

Stacy Baber

Since the 1972 discovery of Fujishima and Honda detecting the occurrence of water splitting on TiO2 electrodes, titanium dioxide's use as a photocatalyst has provoked a broad range of research studies and applications. Applications like air and water-purifying, deodorizing, anti-bacterial use and...

Transitioning to Low Carbon Power Generation by Integrating Renewables with Fossil Energy

Nov 7, 2010

Michael Matuszewski

It is expected that environmental regulations will be enacted to restrict the amount of carbon emissions from today's power plants. As such, it is likely that carbon capture and sequestration (CCS) technologies will be added to both new and existing coal-fired power plants to achieve compliance...

Hydrogen Production by Reforming of Logistic Diesel Fuel in Supercritical Water

Mar 23, 2010

Carsten Cremers

Compared with other fuels, diesel fuels still have significant advantages in terms of logistic properties such as energy density, availability and ease of handling. However, diesel fuels also have their draw backs. For an example, the only established technology to convert the chemical energy of...

Autothermal Reforming of Ethanol in a Fluidized Bed Membrane Reactor for Ultra-Pure Hydrogen Production

Mar 23, 2010

Fausto Gallucci

In recent years, many efforts have been made to develop processes and reactor technologies for the production of cheap, ultra-pure hydrogen that can be used in efficient PEM fuel cells. Nowadays, hydrogen is mainly produced by steam reforming of natural gas in multi-tubular reactors. The main...

Diurnal Cycling of Triacylglycerides in a Chlorophyte Sp.: Implications for the Production of Algal Biofuels

Nov 11, 2009

Keith Cooksey

There is no doubt that crude oil will be depleted eventually. The concept of global warming is now well accepted. Given these twin constraints, it behooves us to find alternative fuels, especially liquid ones for transportation. Microalgae have the potential to both reduce increases in greenhouse...

Battery Design for Large Lithium and Zinc Batteries

Nov 11, 2009

G. J. Suppes

A battery design is being evaluated which is particularly useful for larger battery applications such as in PHEV and electrical grid applications. Preliminary studies validate the approach. Parametric studies are discussed which define performance curve.

Growth Kinetic Study of Chlorella Vulgaris

Nov 11, 2009

Jinsoo Kim

Algae are simple autotrophic organisms that produce complex organic compounds from simple inorganic molecules such as carbon dioxide using energy from light or inorganic chemical reactions. These complex organics include a substantial amount of triacylglycerol which can be readily converted into...

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,...

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...
