High-entropy nanoalloys (HENA) have widespread applications in materials science and applied physics. However, their synthesis is challenging due to slow kinetics that cause phase segregation, ...

Although thermionic emission in traditional materials, such as copper and silicon, has been well-explained by a theoretical model put forward by British physicist O. W. Richardson in 1901, exactly how ...

(Nanowerk Spotlight) Heat energy can be converted into electricity with very high efficiency through a temperature-induced electron flow process known as thermionic emission. The basic operating ...

Typically, if you want to convert solar energy into electrical energy, you use either photovoltaic (PV) cells, or you use the sunlight to create steam to turn a turbine. Both of these methods are well ...

In this study, five mathematical models were fitted in the absence of space charge with experimental data to find a more appropriate model and predict the emission current density of the ...

Thermionic energy conversion harnesses thermal excitation to emit electrons from a hot cathode into vacuum and collect them at a cooler anode, thereby producing electrical power directly from heat. In ...

Typically, if you want to convert solar energy into electrical energy, you use either photovoltaic (PV) cells, or you use the sunlight to create steam to turn a turbine. Both of these methods are well ...

A Spanish-Italian research group has developed a solid-state thermal-to-electric energy converter based on hybrid thermionic-photovoltaics (TIPV) for different applications. It consists of a ...

1904: British engineer John Ambrose Fleming invents and patents the thermionic valve, the first vacuum tube. With this advance, the age of modern wireless electronics is born. The principle of ...

Researchers discover a new theory that paves the way for the design of better graphene electronics and energy converters. When a metal is heated to a sufficiently high temperature, electrons can be ...
