Scientists have developed a molecular structure that could help create current-generating machines at the nanoscale.

Most chemical elements become superconducting at low temperatures or high pressures, but until now, copper, silver, gold, and the semiconductor germanium, for example, have all refused superconductivity. Scientists have now able to produce superconducting germanium for the first time. Furthermore, they could unravel a few of the mysteries which come along with superconducting semiconductors.

Evidence Of Macroscopic Quantum Tunneling Detected In Nanowires Science Daily (press release) Although quantum mechanics governs the realm of atoms and molecules and smaller, quantum phenomena sometimes “leak up” to macroscopic scales, he said. The ultrathin superconducting nanowires fabricated and measured by Sahu and his co-researchers are ...

Researchers have studied silicon micro and nanofabrication methods, which have a large number of applications. They have found a novel nanopatterned silicon surface that allows almost limitless manipulation of water droplets. Droplet shapes can be tailored freely, and the nanopatterned surface can be made completely water-repellent. On such a surface, a water droplet bounces like a tennis ball.

In an advance toward preventing car windshields and eyeglasses from fogging up, researchers in China are reporting development of a new way to make raspberry-shaped nanoparticles that can give glass a permanent antifogging coating. 

Information carved in stone is not dense but can last thousands of years, whereas today’s silicon memory chips can hold their information for only a few decades. Researchers have now smashed this tradition with a new memory storage medium that can pack thousands of times more data into one square inch of space than conventional chips and preserve this data for more than a billion years!

Without knowing how much of an industrial chemical is being produced, it is almost impossible for scientists to determine if it poses any threat to the environment or human health. Civil engineers now believe they have come up with a novel way of estimating how much of one such material -- titanium dioxide -- is being generated, laying the groundwork for future studies to assess any possible risks.
