Plasma-coated stent

3D plasma coating technique prevents stents from clogging

Materials World magazine
Researchers at the University of Ulster, UK, have developed a 3D plasma coating technique to prevent stents from developing neointima, where thick muscle tissue grows over the surface, leading to the blood vessel narrowing again. Thin films of carbon, ceramics and platinum are coated using the new method to prevent clogging.

Heating up austenitic stainless steels

Materials World magazine
Researchers at Oak Ridge National Laboratory, USA, claim to have developed inexpensive austenitic stainless steels that can withstand higher temperatures while maintaing creep strength and oxidation resistance by introducing aluminium into composition. The drive towards higher operating temperatures, while maintaining creep stremnght and oxidation resistance by introducing aluminium into its composition. that employ austenitic stainless steels in turbine recuperators, heat exchangers, piping and tubing.

New quantum dots can amplify light for tunable lasers

Materials World magazine
Researchers at Los Alamos National Laboratory, New Mexico, USA, have engineered a new version of quantum dots (semiconductor nanocrystals) that can amplify light for cheaper and tunable lasers at a range of wavelenghts at a range of wavelengths.

Biometric fingerprints for anti-counterfeiting

Packaging Professional magazine
ProteXXion, launched by Bayer Technology Services in Germany, is a security and tracking device that uses the biometric fingerprints of individual surfaces to counter fraud in items ranging from packaging to passports. ProteXXion encompasses project management, installation and servicing of the laser surface authentication (LSA) technology invented at Imperial College London, UK. Laser surface authentification combined with RFID tracking device tags could provide an all-encompassing anti-fraud solution. Trials have been conducted on pharmaceutical and tobacco packaging using static scannes on production lines that move up to four metres per second.
