Researchers have developed what they call a simple, one-step method to grow nanowires of germanium from an aqueous solution. Their process could make it more feasible to use germanium in lithium ion batteries.
One of the most promising technologies for future quantum circuits are photonic circuits, i.e. circuits based on light (photons) instead of electrons (electronic circuits). First, it is necessary to create a stream of single photons and control their direction. Researchers around the world have made all sorts of attempts to achieve this, but now scientists have succeeded in creating a steady stream of photons emitted one at a time and in a particular direction.
Glass has many applications that call for different properties, such as resistance to thermal shock or to chemically harsh environments. Glassmakers commonly use additives such as boron oxide to tweak these properties by changing the atomic structure of glass. Now researchers have for the first time captured atoms in borosilicate glass flipping from one structure to another as it is placed under high pressure.
Researchers have developed a synthetic virus. This can be used in the future to 'package' new generations of medicines consisting of large biomolecules and to deliver them into diseased cells, by a natural process.
A new high-tech membrane is made of high-quality steel and is more stable and more flexible than conventional filters, also more environmentally-compatible because only inert gas and electrical power are needed for its manufacture.
Silicon has been the most successful material of the 20th century, with major global industries and even a valley named after it. But silicon may be running out of steam for high performance/low power electronics. As silicon strains against the physical limits of performance, could a material like InGaAs provide enough of an improvement over silicon that it would be worth the expense in new equipment lines and training to make the switch worthwhile?
