Spiky ferrofluid thrusters can move satellites

13-Jul-2017 - Brandon Jackson, a doctoral candidate in mechanical engineering at Michigan Technological University, has created a new computational model of an electrospray thruster using ionic liquid ferrofluid -- a promising technology for propelling small satellites through space. Specifically, Jackson ...

Supercomputers join search for 'cheapium'

07-Jan-2014 - In the search for cheaper materials that mimic their purer, more expensive counterparts, researchers are abandoning hunches and intuition for theoretical models and pure computing power. In a new study, researchers from Duke University’s Pratt School of Engineering used computational methods to ...

Chemists grow crystals with a twist -- and untwist

22-Jul-2010 - Chemists from New York University and Russia's St. Petersburg State University have created crystals that can twist and untwist, pointing to a much more varied process of crystal growth than previously thought. Their work, which appears in the latest issue of the Journal of the American Chemical ...

Chemist stitches up speedier chemical reactions

New details about the Piers catalyst will help chemical industry improve products

11-May-2010 - Some people have streets named after them. Warren Piers, a chemistry professor at the University of Calgary, has a catalyst penned after him. And in a paper published in the online edition of Nature Chemistry, Piers and former graduate student Edwin van der Eide reveal the inner workings of the ...

Water droplets shape graphene nanostructures

21-Dec-2009 - Graphene -- A single-atom-thick sheet of carbon, like those seen in pencil marks -- offers great potential for new types of nanoscale devices, if a good way can be found to mold the material into desired shapes. Chemists at the University of Illinois at Chicago say it's possible, reporting that ...

3-D imaging: First insights into magnetic fields

01-Apr-2008 - 3-D images are not only useful in medicine; the observation of internal structures is also invaluable in many other fields of scientific investigation. Recently, researchers from the Hahn-Meitner-Institute (HMI) in Berlin in cooperation with University of Applied Sciences in Berlin have ...

Tiny Tubes for Biotransport

Researchers clarify cellular uptake mechanisms for carbon nanotubes

08-Dec-2005 - They look like the tiniest of needles and have the potential to channel pharmaceutical agents into targeted living cells: carbon nanotubes are long, thin, nanoscale tubes made of one (or more) layers of carbon atoms in a graphite-like arrangement. Drugs can be hooked on to their exteriors and can ...

Molecular Needles: Carbon nanotubes inject antimycotics into cells and increase their effectiveness

21-Sep-2005 - Putting pharmaceutical agents into the body isn't hard, but getting them into targeted areas can be problematic. If drugs aren't taken up by a large enough proportion of cells, a suitable "transport agent" must be used. A French and Italian research team has successfully used carbon nanotubes as ...

Injections without the needles

Cobranding cooperation between Rösch AG Medizintechnik and Bayer AG

22-Nov-2001 - For those patients who go weak at the knees at the mere thought of a syringe needle, it's long been a dream: the needle-free injection. Now, thanks to the development of the INJEXTM system by the Berlin-based Rösch AG Medizintechnik, their wish has come true. Liquid drugs can now be injected ...

FDA approves Roche’s qualitative Amplicor HCV Test

First approved PCR-based test to detect Hepatitis C Virus

10-Jul-2001 - The U.S. Food and Drug Administration (FDA) has granted marketing approval for Roche’s two hepatitis C tests designed to directly detect the presence of the Hepatitis C virus (HCV) in the blood. Roche’s Amplicor HCV Test (version 2.0) and Cobas Amplicor HCV Test (version 2.0) are the first ...
