Three-Atom Thick Crystal is Capable of Toggling Between Two Electrical States

July 2, 2014

0 Comments

New research from Stanford University shows how to make a three-atom thick crystal that would toggle like a light switch between conductive and non-conductive structures, opening the door to flexible electronic materials. Do not fold, spindle or mutilate. Those instructions were once printed on punch cards that fed data to mainframe computers. Today’s smart phones […]

MIT Develops Membrane That Can Separate Highly Mixed Oil-Spill Residues

July 1, 2014

0 Comments

A newly developed membrane can separate highly mixed fine oil-spill residues, processing large quantities of the finely mixed materials back into pure oil and water. Whenever there is a major spill of oil into water, the two tend to mix into a suspension of tiny droplets, called an emulsion, that is extremely hard to separate […]

Kit Researchers Create Mechanical Invisibility Cloak

June 23, 2014

0 Comments

Using metamaterials, researchers at the Karlsruhe Institute of Technology developed a mechanical invisibility cloak that hides objects from touch. In the past years, invisibility cloaks were developed for various senses. Objects can be hidden from light, heat or sound. However, hiding of an object from being touched still remained to be accomplished. KIT scientists have […]
