Preparation and Characterization of Various Nanofluids

Williams W.C., Bang I.C., Forrest E., Hu L.W., Buongiorno J., Massachusetts Institute of Technology, US

As part of an effort to evaluate water-based nanofluids for nuclear applications, preparation and characterization has been performed for nanofluids being considered for MIT’s nanofluid heat transfer experiments. Three methods of generating these nanofluids are [...]

Enhancement of Oxygen Transfer in Fermentation by Use of Functionalized Magnetic Nanoparticles

Olle B., Bromberg L., Hatton T.A., Wang D.I.C., Massachusetts Institute of Technology, US

Maintaining an adequate oxygen supply to aerobic cell cultures has been a long-standing problem in fermentation technology. Insufficient oxygen transfer rates limit cell growth and ultimately process productivity. Our approach to reducing the oxygen transport [...]

Destruction of Organophosphate Agents by Recyclable Catalytic Magnetic Nanoparticles

Bromberg L., Hatton T.A., Massachusetts Institute of Technology, US

Organophosphorus pesticides and warfare agents are not readily hydrolyzed in aqueous media without applying extremes of pH, heat, or bleach. We show that suspensions of magnetite (Fe3O4) nanoparticles modified with a common antidote, 2-pralidoxime (PAM), [...]

Functionalized Nanoporous Ceramic Sorbents for Removal of Mercury and Other Contaminants

Mattigod S.V., Fryxell G.E., Skaggs R., Parker K.E., Pacific Northwest National laboratory, US

A new class of high-performance nanoporous sorbents has been developed for heavy metal removal that overcomes the deficiencies of existing technologies. These novel materials are created from a combination of synthetic mesoporous ceramic substrates that [...]

Monometallic nano-catalysts for the reduction of perchlorate in water

Wang D.M., Lin H-Y, Huang C.P., University of Delaware, US

Perchlorate removal in a clean, cost-effective and public-acceptable approach is one of the important issues for current drinking water treatment. Catalytic membrane (CM) was prepared by coating monometallic catalysts of the nano-size onto supports by [...]

Photovoltaics Innovation and Commercialization in Ohio

Giolando D.M., Collins R., Davis R.J., Photovoltaics Innovation and Commercialization (PVIC), US

The Center for Photovoltaics Innovation and Commercialization (PVIC) was funded as a means of strengthening the photovoltaics research and manufacturing base in Ohio. Activities revolve around eliminating market barriers currently facing companies in the photovoltaics [...]

Active Coatings Technologies for Customized Military Coating Systems

Zunino III J.L., U.S. Army ARDEC, US

The main objective of the U.S. Army’s Active Coatings Technologies Program is to develop technologies that can be used in combination to tailor coatings for utilization on Army Materiel. The Active Coatings Technologies Program, ACT, [...]

Harnessing the power of the sun, the wind…and the media? Why cleantech companies need to innovate both in the lab and in their communications

Allison M., Waggener Edstrom, US

As clean technologies move into even greater prominence in the minds of consumers and on the screens and pages of the media world, the noise level surrounding the clean tech environment will rise as well. [...]

Good Policy Makes for Good Business – and Visa Versa

Cinnamon B., Akeena Solar, US

In rapidly emerging industries like Clean Technology, lawmakers are challenged to come up with good public policy that will accomplish society’s goals. Hence new, well-funded policies like the 43.2 billion California Solar Initiative and the [...]

Nano hetero nuclear fuel structure

Popa-Simil L., LAVM, Inc., US

The direct energy conversion of nuclear energy requires nano-structured nuclear fuel. The principle of the radiation energy direct conversion is the usage of the knock-on electrons produced by the moving particle interaction with the lattice. [...]
