Lasers enable engineers to weld ceramics, no furnace required Posted: 22 Aug 2019 11:19 AM PDT Smartphones that don't scratch or shatter. Metal-free pacemakers. Electronics for space and other harsh environments. These could all be made possible thanks to a new ceramic welding technology. The process works in ambient conditions and uses less than 50 watts of laser power, making it more practical than current ceramic welding methods that require heating the parts in a furnace. |
Materials scientists build a synthetic system with compartments like real cells Posted: 22 Aug 2019 08:34 AM PDT Polymer chemists and materials scientists have achieved some notable advances that mimic Nature, but one of the most common and practical features of cells has so far been out of reach -- intracellular compartmentalization. Now researchers tell how they take advantage of differences in electrical charge to create an 'all aqueous,' water-in-water construct that achieves compartmentalization in a synthetic system. |
Computer model could help test new sickle cell drugs Posted: 22 Aug 2019 07:14 AM PDT A new computer model that captures the dynamics of the red blood cell sickling process could help in evaluating drugs for treating sickle cell disease. |
New technique could streamline design of intricate fusion device Posted: 21 Aug 2019 02:37 PM PDT Stellarators, twisty machines that house fusion reactions, rely on complex magnetic coils that are challenging to design and build. Now, a physicist has developed a mathematical technique to help simplify the design of the coils. |
Physicists create world's smallest engine Posted: 21 Aug 2019 09:55 AM PDT The research explains how random fluctuations affect the operation of microscopic machines like this tiny motor. In the future, such devices could be incorporated into other technologies to recycle waste heat and thus improve energy efficiency. |
