Superconductivity already has a variety of practical applications, such as medical imaging and levitating transportation like the ever-popular maglev systems. However, to ensure that the benefits of applied superconductors keep spreading further into other technological fields, we need to find ways of not only improving their performance, but also making them more accessible and simpler to fabricate.
In this regard, magnesium diboride (MgB

A major roadblock to computational design of high-entropy alloys has been removed, according to scientists at Iowa State University and Lehigh University. Engineers from the Ames Lab and Lehigh University s Department of Mechanical Engineering and Mechanics have developed a process that reduces search time used for predictive design 13,000-fold.
According to Ganesh Balasubramanian, an associate professor at Lehigh, the goal of the team s research was to accelerate the computational modeling of complex alloys. The tools available for creating random distribution of atoms in materials simulation models, he says, have been used for many, many years now and are limited in their reach for fast

A thermoelectric device is an energy conversion device that utilizes the voltage generated by the temperature difference between both ends of a material; it is capable of converting heat energy, such as waste heat from industrial sites, into electricity that can be used in daily life. Existing thermoelectric devices are rigid because they are composed of hard metal-based electrodes and semiconductors, hindering the full absorption of heat sources from uneven surfaces. Therefore, recent studies were actively conducted on the development of flexible thermoelectric devices capable of generating energy in close contact with various heat sources such as human skins and hot w
