Superconductors are materials that can achieve a state known as superconductivity, in which matter has no electrical resistance and does not allow the penetration of magnetic fields. At low temperatures, these materials are ...
One of the most abundant iron-containing minerals on Earth, and also the oldest known magnetic material, is magnetite, Fe3O4. Magnetite has applications in many fields, such as the study of paleomagnetism—magnetism in rocks ...
To create efficient energy storage solutions and actuators, engineers need materials with a high dielectric constant. The dielectric constant is essentially the ratio of a substance's permittivity (i.e., its ability to store ...
Over the past few years, thermoelectric generators have become the focus of a growing number of studies, due to their ability to convert waste heat into electrical energy. Quantum dots, semiconductor crystals with distinctive ...
(Phys.org)—The large amount of waste heat produced by power plants and automobile engines can be converted into electricity due to the thermoelectric effect, a physics effect that converts temperature differences into electrical ...
(Phys.org)—Electrons can move through graphene with almost no resistance, a property that gives graphene great potential for replacing silicon in next-generation, highly efficient electronic devices. But currently it's ...
(Phys.org)—Capacitors are widely used in electrical circuits to store small amounts of energy, but have never been used for large-scale energy storage. Now researchers from Japan have shown that the right combination of ...
(Phys.org) —Today when an electric vehicle is plugged into the grid, it's almost always in charge mode, meaning it consumes power. But it's also possible for an electric vehicle to operate in discharge mode, in which it ...
(Phys.org) —Researchers have demonstrated a new class of high-energy battery, called a "molten-air battery," that has one of the highest storage capacities of any battery type to date. Unlike some other high-energy batteries, ...
A new analysis by the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, provides the first direct evidence of the ...
