Volcanoes and Nanotechnology

Etna produces catalyst: direct synthesis of carbon nanotubes with volcanic rock


Since their discovery in the early 1990s, carbon nanotubes and carbon nanofibers - tiny structures made of pure carbon - have been used in a wide variety of applications. They have become indispensable in the nanosciences and nanotechnology. However, because their production on an industrial ...


Nanotechnology could promote hydrogen economy


In a new twist, Rutgers scientists are using nanotechnology in chemical reactions that could provide hydrogen for tomorrow's fuel-cell powered clean energy vehicles. In a paper in the Journal of the American Chemical Society, researchers at Rutgers, The State University of New Jersey, describe ...


A new method for coating individual luminous nanocrystals (quantum dots) with silicon dioxide


Great things are expected from quantum dots: they are supposed to mark tumors, help improve large flat-screens, and be the foundation for the optical data processing of the future. Quantum dots are nanoscopic crystals, which are so small that their optoelectronic properties resemble those of ...


Tracking Down the Scent of Sweat

Researchers identify new sulfur-containing scent molecules in sweat


Sometimes, people just don't smell good - and not only in the figurative sense. The sense of smell plays an important role in interpersonal relations. The human armpit contains chemical substances that - at least in premodern times - probably provided direction for the selection of a ...


Asahi Glass Pioneers World's First Practical Application of Fluorinated Resin Recycling Technology


Asahi Glass Co., Ltd. and Nittetsu Chemical Engineering Ltd. have successfully pioneered the first practical application technology for breaking down and recycling used fluorinated resin in order to reuse the material. The break decomposition/recycling plant operation launch within the ...


Injecting carbon dioxide to extract methane from methane hydrate deposits?


Two of the most pressing problems of our time are the ever-dwindling fossil fuels and the threatening climate change resulting from the increasing release of carbon dioxide. A means to simultaneously remove carbon dioxide while also producing methane would truly resemble the Philosopher's ...


Breaking down pollutants with sunlight

Carbon-doped titanium dioxide as an effective photocatalyst


The sun is a virtually inexhaustible source of energy, which isn't just useful for the production of electrical energy (solar cells). For example, when converted into chemical energy, it can be used to break down pollutants. Researchers at the University of Erlangen-Nürnberg have now developed ...


Designed antitumor agent with a highly promising pharmacological profile


Modern methods of "high-throughput screening" make it possible to search for new pharmaceuticals in giant-though sometimes quite randomly compiled-substance libraries. In contrast, an interdisciplinary team at the Sloan-Kettering Institute for Cancer Research in New York is depending on ...


Bayer wins BDI Environmental Prize

Complexing agent helps to reduce impact on inshore waters


Berlin, June 11, 2002 - On June 11, 2002, the Federation of German Industry (BDI) awarded Bayer AG its Environmental Prize. The jury rewarded Bayer for its development of Baypure® CX 100, an environmentally friendly alternative to conventional complexing agents. These are used in many everyday ...


IDBS Introduces New Chemical Information Technologies At American Chemical Society Conference

ChemIQ(TM) and ChemXtra(TM) Allow Users to Bring Chemical Intelligence Into Any Software Environment


ORLANDO, Fla., Apr 8, 2002 - ID Business Solutions (IDBS) today unveiled ChemIQ(TM), a powerful chemical toolkit for developing chemically-aware client software applications and ChemXtra(TM), a new Oracle data cartridge for indexing and searching chemical structures and reactions in Oracle. ...
