source:ALL3DPLaser (light amplification by stimulated emission of radiation) beams are highly concentrated beams of light with high frequency. This results in a high-energy beam of light that can be focused on a small area. Whenever a laser beam is focused on a material, it rapidly heats the focused area, converting the light energy to heat energy. The heated material melts and blows away, resulting in a hole.Laser cutting allows you to cut a wide variety of materials, ranging from a thin sheet of paper to even a thick metal plate using laser beams. However, different types of lasers can yield...

source:Science and TechnologyIt's yet to be invented but it’s hard to imagine a more revolutionary advance in energy storage than a battery that never loses its charge.The possibility came into vogue in 2019, with Canadian scientists proposing a shift away from lithium-ion cells, which rely on chemical reactions, to those energised using quantum mechanics.The concept involves harnessing the power of “excitonic energy” or the state in which an electron absorbs sufficiently charged photons of light.The problem, of course, is that it was – and continues to be – just an idea. Albeit it’s one t...

source:Phys.ORGScientists pursuing better performance in a well-known type of iron-based magnet also discovered wide-gap semiconducting behavior and a quantum state useful for quantum information processing—all in a single low-cost material that has been in existence for decades.Scientists at the U.S. Department of Energy's Critical Materials Institute, or CMI, study ways to make lower-cost, easier-to-obtain materials used as ingredients in technologies that are in demand now or are developing for the future. In this case, the researchers were investigating ways to create a stronger iron-b...
