source:New AtlasRadio waves don't travel well through water, which is why devices such as ROVS (remotely operated vehicles) have to be linked to their operator via a communications cable. According to a new study, however, solar panels may soon allow for practical underwater light-based communications.First of all, various groups have already used pulses of laser light to transmit data underwater. The functionality of such systems has been limited, though, due to the fact that the transmitter which emits the light has to be precisely aligned with the photodiode that receives it. Because of...

source:EurekAlertThermoelectric materials convert heat to electricity and vice versa, and their atomic structures are closely related to how well they perform.Now researchers have discovered how to change the atomic structure of a highly efficient thermoelectric material, tin selenide, with intense pulses of laser light. This result opens a new way to improve thermoelectrics and a host of other materials by controlling their structure, creating materials with dramatic new properties that may not exist in nature.“For this class of materials that’s extremely important, because their functional p...

source:Wonderful EngineeringPrecious Rare Earth elements (REE) have been recovered from waste by a team of researchers at Rice University. These elements are actually the metals that have magnetic and electronic properties crucial to modern electronics and green technologies from waste at high yields. They have utilized a process that is gentler on the environment. It consumes less energy and reduces the stream of acid commonly used to recover the elements into a drizzle, which is a huge achievement.Rare earth metals are not actually rare. For example, cerium is more abundant than copper, and ...
