A sticky-spaghetti-with-meatballs model may be sufficient to describe how the nucleus in each of our cells selectively allows the entrance and exit of certain molecules, while blocking others to protect genetic material and normal functions of the cell.
Researchers have, for the first time, experimentally demonstrated that polycrystalline fused films of hafnium and zirconium oxides with a thickness of just 2.5 nm retain their ferroelectric properties. This could potentially be used to develop non-volatile memory elements.
A team of researchers has predicted the existence of a new state of matter in which current flows only through a set of surface channels that resemble an hourglass. These channels are created through the action of a newly theorized particle, dubbed the 'hourglass fermion', which arises due to a special property of the material.
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.
