Nano-sized silver particles open way to new breed of antimicrobial materials
Scientists can now incorporate silver particles into polypropylene to produce an anti-microbial material that could be used in anything from carpets, to napkins and surgical masks.
Silver has been medically proven to kill over 650 disease-causing organisms in the body and is also very safe. By combining silver and polypropylene to produce an organic-inorganic fibre, researchers have produced the first safe, anti-microbial fibre with a wide range of possible applications.
Polypropylene fibre is one of the most widely used synthetic fibres in the textile industry because it is cheaper and stronger than other synthetic fibres. Researchers have demonstrated, in a paper to be published in the July issue of Polymer International, available online in June, that they can produce two types of fibres both with silver particles distributed evenly along the length of the fibre.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
