Silicone rubber and other rubber-like materials have a wide variety of uses, but in almost every case they must be reinforced with particles to make them stronger or less permeable to gases or liquids. University of Cincinnati (UC) chemistry professor James Mark and colleagues have devised a technique that strengthens silicone rubber with nanoscale particles, but leaves the material crystal clear.
Silicone rubber is often reinforced by tiny particles of silica (the primary component of sand and the mineral quartz). However, those silica particles can cloud the silicone rubber, which is a problem for protective masks, contact lenses and medical tubing that rely on silicone rubbers transparency.
Mark, along with graduate student Guru Rajan, UC professor Dale Schaefer, UC associate professor Gregory Beaucage and Yeungnam University (Korea) professor Gil Sur reported on their new technique in the August 15 issue of the Journal of Polymer Science Part B: Polymer Physics.

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...
