New technology detects chemical weapons in seconds

Scientists at Queen's University Belfast are developing new sensors to detect chemical agents and illegal drugs which will help in the fight against the threat of terrorist attacks.

Tracing ultra-fine dust

Limit values for fine dust emissions are based on total particle weight. It is the ultra-fine particles, however, that are particularly harmful to health. A new technique separates them by size and identifies their composition ...

Nanotechnology gets a new light touch

(PhysOrg.com) -- Building the super-fast computers of the future has just become much easier thanks to an advance by Australian researchers that lets them grab hold of tiny electronics components and probe their inner structure ...

Multi-laboratory study sizes up nanoparticle sizing

As a result of a major inter-laboratory study, the standards body ASTM International has been able to update its guidelines for a commonly used technique for measuring the size of nanoparticles in solutions. The study, which ...

Formation of the smallest droplet of acid

Exactly four water molecules and one hydrogen chloride molecule are necessary to form the smallest droplet of acid. This was the result of work by the groups of Prof. Dr. Martina Havenith (physical chemistry) and Prof. Dr. ...

Creating the astro-comb to locate Earth-like planets

Researchers at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. have created an "astro-comb" to help astronomers detect lighter planets, more like Earth, around distant stars. The Harvard group will present ...

Polarizers may enhance remote chemical detection

Chemists can analyze the composition of a suspected bomb -- without actually touching and possibly detonating it -- using a technique called laser-induced breakdown spectroscopy, or LIBS. The tool is also commonly used for ...
