A team of scientists from Lockheed Martin have produced a small satellite cooling system, the high power Microcryocooler, which is the lightest on the market and three times more powerful than the company’s first design. This design will pave the way for smaller and more compact IR sensor systems and novel sensor configurations. "The High Power Microcryocooler is making a … [Read more...]
Lithium Atoms Turn Graphene into a Superconductor
Physicists in Canada and Germany have proved that graphene turns into a superconductor when ‘decorated’ with lithium atoms, which could lead to a new generation of superconducting nanoscale devices, according to Nanotechweb.org. In 2005, physicists demonstrated that when chemically treated, graphite could exhibit superconducting properties. “Theorists identified the … [Read more...]
Composite Metal Is 40 Percent Lighter than Steel with Eightfold Thermal Conductivity
Materion Technical Materials has announced the release of eStainless, a new composite material comprised of a lightweight, highly conductive aluminum core within an outer skin of ductile stainless steel. eStainless maintains 83 percent of the stiffness of solid stainless steel while weighting 40 percent less and exhibits eight times its thermal conductivity, making it an … [Read more...]
Superconducting Refrigerator Cools via Tunneling Cascade
Researchers from Italy and France have proposed a new design for a superconducting refrigerator that uses a series of steps to more effectively cool objects down to temperatures near absolute zero. Conventional superconducting refrigerators rely a array of superconductors (S), normal metals (N) and tunnel barriers (I) that are arranged in a symmetric configuration (SINIS or … [Read more...]
New Magnetocaloric Material Could Lead to Greener Refrigerators
The recent discovery of a new magnetocaloric material with intriguing characteristics could lead to a greener method of cooling, potentially providing a more environmentally-friendly alternative to standard refrigeration. A joint team of researchers from Canada and Bulgaria have developed a new method of green cooling by identifying a multiferroic compound, HoMn2O5, that could … [Read more...]
