Light is a form of electromagnetic radiation that exists all around us, in nature as well as in man-made applications. It's the manipulation of these light waves that made possible some of the most widely used technologies of today, from cameras to microwave ovens and medical imaging machines.A new device, deve...
Solar cells are regarded as one of the key technologies towards a sustainable energy supply and have already found many applications, mostly in situations where electrical power from the grid is unavailable, such as in remote area power systems, Earth-orbiting satellites and space probes.Recently they have become mo...
Although they did not find out how Moses could separate the water of the Red Sea, they were able to do the same with a mass of sand grains, in an experiment which proves that no outside force is necessary to make identical molecules part.Scientists at the Rutgers University, New Jersey, proved that two identical pop...
Scientists studying robots encounter many problems in their endeavors, and they usually turn to Mother Nature to solve their problems. For instance, how would a robot move?Walking in an upright, human-like position is pretty difficult to achieve, and the most evolved humanoid robot only walks as fast as a clumsy thre...
Seeing is not all about light, as sounds often produce accurate images of what light alone can't show us. Many applications use sound as imaging technique, like radars, sonars, echographs and telecommunication devices. Processing acoustic signals has just become more efficient with a new imaging algorithm that ...
Magnetic avalanches could wipe clean entire hard disk drives, so a new model of this phenomenon helps explain how and why they appear, but most importantly, how to prevent them in order to create new and more reliable memory storage devices.Two magnets pushed together create an avalanche of magnetic activity, used t...
New laser technique can produce parts with intricate features and complex internal characteristics by consecutively melting thin layers of powdered materials applied onto the initial object. Each layer is machined right after it was applied, thus molding the final part step by step.This laser sculpture can be used t...
An atom laser is similar to an optical one and is in fact a coherent beam of atoms that behaves like a wave. Though a relatively recent discovery, still in its 'infancy', this technology could soon have many practical applications, like in extremely precise measurements."When doing precise measurements of ...
Internal combustion engines are now powering the vast majority of automobiles, motorcycles, trucks, boats and are also used in various industrial applications. They are so widespread because they can provide high power to weight ratios together with excellent fuel energy-density.However, their efficiency is relative...
New research provides extremely broad bandwidth and could bring the next generation of wireless data connections that will transfer a 4.7 GB DVD in just a few seconds. This new product will finally get us rid of the tangle of wires that lurk under the desk.Scientists at the Georgia Electronic Design Center (GEDC) at...
