source:capitalMining companies have long been instrumental in influencing the speed and direction of the global green transition. This is due to their heavy dependence still on fossil fuels, especially coal. With a number of mines using inordinately large amounts of water, energy and fuel to run their operations, investors are concerned that they may now be pushing back the green transition by several years, if not decades. This concern is not restricted to resource usage, but also the impact of mining activities on ecologically delicate areas.Have a confidential tip for our reporters?Get In T...

source:azomFerroelectric materials are known as substances that exhibit spontaneous electrical polarization. Polarization implies the isolation of the negative and positive charges present inside a material.The ImpactHafnia-based ferroelectric materials seem to possess numerous advantages for computer memory. They provide high durability, lower operating power, speed, and the potential to hold data when power is shut down. But scientists do not completely comprehend such materials.This study developed a creative bulk hafnia-based ferroelectric material. The outcomes offer insights into how suc...

source:nanowerk(Nanowerk News) Erbium-doped fiber amplifiers (EDFAs) are devices that can provide gain to the optical signal power in optical fibers, often used in long-distance communication fiber optic cables and fiber-based lasers. Invented in the 1980s, EDFAs are arguably one of the most important inventions, and have profoundly impacted our information society enabling signals to be routed across the Atlantic and replacing electrical repeaters.What is interesting about erbium ions in optical communications is that they can amplify light in the 1.55 mm wavelength region, which is where sil...
