Partial discharge detector puts condition monitoring on the agenda LONDON, June 2, 2014 /PRNewswire/ -- Power-engineering specialist EA Technology has produced the world's most effective partial discharge locator for high-voltage air insulated switchyard equipment and it's here in the USA. The only instrument of its kind, the rugged, handheld, battery-powered PD Hawk(TM) is straight forward to operate and uniquely fast and accurate. Allowing electrical engineers to scan...

Fossil Amber Offers New Insights Into Glass Formation
2013-05-15 08:39:20

April Flowers for redOrbit.com - Your Universe Online In a new study from researchers at Texas Tech University, scientists have discovered that the structure of amber barely changes even after tens of millions of years. A report of the research, published in Nature Communications, could help answer fundamental questions about how glasses form. "What we found was that in 20 million years, the amber changed density by only 2.1 percent. What we found challenges the way we look at...

Potential for optoelectronics, solar cells, valleytronics and more When the dry lubricant, molybdenum disulfide, is stripped down to a single layer of atoms, a tightly bound quasi-particle comprised of two electrons and a hole forms with unique spin and valley properties, researchers from Case Western Reserve University and colleagues discovered. These charged quasi-particles, called negative trions, can be manipulated to change the light absorbed and emitted from this two-dimensional...

By Harnessing Friction Between Surfaces, Triboelectric Generator Produces Electricity
2012-07-10 10:51:47

Polymer power Researchers have discovered yet another way to harvest small amounts of electricity from motion in the world around us — this time by capturing the electrical charge produced when two different kinds of plastic materials rub against one another. Based on flexible polymer materials, this "triboelectric" generator could provide alternating current (AC) from activities such as walking. The triboelectric generator could supplement power produced by nanogenerators that...

Strong attraction that arises between biological objects with random patches of electric charge on an otherwise neutral surface may partly explain pattern recognition in biology Theoretical physicist Ali Naji from the IPM in Tehran and the University of Cambridge, UK, and his colleagues have shown how small random patches of disordered, frozen electric charges can make a difference when they are scattered on surfaces that are overall neutral. These charges induce a twisting force that is...

Super-Slippery Material Could Make Ketchup Slide Out More Easily
2011-11-14 11:52:04

Scientists have developed one of the most slippery materials ever made after copying the leaves from a carnivorous plant. The material can be used as for self-cleaning surfaces that never get dirty and to coat the inside of bottles and jars to help food escape more easily. The new material repels both water and oil based liquids, making condiments like tomato ketchup or jam slide out easily. "It is a problem we all face — we have a bottle of sauce and we are trying to get the...

Scientists develop new nanomaterial that ℠steers´ current in multiple dimensions Scientists at Northwestern University have developed a new nanomaterial that can "steer" electrical currents. The development could lead to a computer that can simply reconfigure its internal wiring and become an entirely different device, based on changing needs. As electronic devices are built smaller and smaller, the materials from which the circuits are constructed begin to lose their...

Completing the story they started by creating synthetic magnetic fields,* scientists from the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland, have now made atoms act as if they were charged particles accelerated by electric fields. Reported in the journal Nature Physics,** these synthetic electric fields make each atom in a gas act, individually, as if it were a charged particle, but collectively they...

Yale University researchers say they've discovered a repulsive light force that can be used to control components on silicon microchips. The scientists said their finding is important because it means future nanodevices might be controlled by light rather than electricity. The same Yale team of scientists previously discovered an attractive force of light and showed how it could be manipulated to move components in semiconducting micro- and nano-electrical systems. Now they've discovered a...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
