Harvesting electricity from condensation could take renewable power to remote areas (Photo...

MIT researchers have found a way to generate small amounts of electricity from condensation, by having electrically-charged droplets jump between superhydrophobic (water-repelling) and hydrophilic (water-attracting) metal plates. The advance could be especially useful in remote areas or developing countries, not least because it produces clean water as a side product.  Read More

Scientists have established that ultrasound waves can spin a 200 nanometers wide rod up to...

Scientists at the National Institute of Standards and Technology (NIST) have discovered that a gold nanorod submerged in water and exposed to high-frequency ultrasound waves can spin at an incredible speed of 150,000 RPM, about ten times faster than the previous record. The advance could lead to powerful nanomotors with important applications in medicine, high-speed machining, and the mixing of materials.  Read More
