(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 ...

When a metal is heated to a sufficiently high temperature, electrons can be ejected out from the surface in a process known as the thermionic emission, a process that is similar to the evaporation of ...

Engineers at Stanford have developed a process which can harness the light and heat of the sun simultaneously, which could lead to solar cells that are twice as efficient as those currently available.

During the experiments, Jiang et al precisely delivered laser packages with a pulse duration of 5 nanoseconds, and a pulse energy of up to 600 mJ to carbonaceous supports to generate an obvious plasma ...

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 ...

Ubiquitous in the field of electric propulsion, thermionic hollow cathodes are electron sources which utilize thermionic emission from a low work function insert material to achieve large extracted ...

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: thermionic ...

DURING our work on the available thermionic emission from mixtures of the alkaline earth oxides (barium, strontium and calcium oxides), we have studied the properties of the system barium ...

Solar thermal technology [1], is promising for both small and utility scale renewable energy systems and solar thermionics [2] is an emerging technology where solar energy heats a metal such that ...
