Researchers who are working to develop wearable electronics have reached a milestone: They are able to embroider circuits into fabric with 0.1 mm precision - the perfect size to integrate electronic components such as sensors and computer memory devices into clothing.
Scientists report that silver nanoparticles and coatings do wash off of commercially available garments in the laundry but at negligible levels. They also found that even low concentrations of silver on clothing kept microbes at bay.
Research scientists have developed a special type of flake-like zinc-phosphate nanoparticles. These nanoparticles are ten times as long as they are thick. As a result of this anisotropy, the penetration of gas molecules into the metal is slowed down.
Researchers have designed and fabricated a flexible lens array that adapts its optical properties when the sheet camera is bent. This optical adaptation enables the sheet camera to produce high quality images over a wide range of sheet deformations.
A research team fabricated nanoscrolls made from graphene oxide flakes and was able to control the dimensions of each nanoscroll, using both low- and high-frequency ultrasonic techniques. The scrolls have mechanical properties that are similar to graphene, and they can be made at a fraction of the cost.
Researchers have combined the benefits of organic and inorganic electronic materials in a new type of hybrid inks. This allows electronic circuits to be applied to paper directly from a pen, for example.
In phase transitions, for instance between water and water vapour, the motional energy competes with the attractive energy between neighbouring molecules. Physicists have now studied quantum phase transitions in which distant particles also influence one another.
Physicists have discovered a topological metal, PtSn4 (platinum and tin), with a unique electronic structure that may someday lead to energy efficient computers with increased processor speeds and data storage.
An international team of physicists has discovered that applying a magnetic field to a non-magnetic metal made it conduct 70% more electricity, even though basic physics principles would have predicted the opposite.
