Heat energy can be converted into electricity with very high efficiency through a temperature-induced electron flow process known as thermionic emission. Thermionic energy converters have been used ...

THE thermionic valve is an invention which has vastly increased the powers and range of wireless telegraphy. Like many other inventions, the telephone, for instance, it is simple in its essential ...

THE modern thermionic valve has now become of world-wide importance, not only in connexion with radio broadcasting, but also in its many applications in scientific and commercial instruments, and ...

Hybrid thermionic-photovoltaic systems are described as an upgraded version of pure thermionic converters, as they add the ability to harvest photons in a photovoltaic anode and produce an ...

Although the 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 ...

He began to reanalyze thermionic energy conversion technology that was used by NASA in the 1950s and 1960s. From there, he used his knowledge and skills gained from the Purdue Certificate in ...

The SU3800 and SU3900 from Hitachi are powerful and versatile thermionic emitter variable pressure SEMs. The extra-large stage and chamber of the SU3900 make it best suited for the study of large, ...
