Thermoacoustic heat engine - Wikipedia

Thermoacoustic heat engine - Wikipedia

Thermoacoustic engines (sometimes called "TA engines") are thermoacoustic devices which use high-amplitude sound waves to pump heat from one place to another, or conversely use a heat difference to induce high-amplitude sound waves. In general, thermoacoustic engines can be divided into standing wave and travelling wave devices.

Stanford team demonstrates a graphene-based thermal-to-electricity conversion technology | Graphene-Info | Thermal to electric conversion | Scoop.it
Researchers at Stanford University have recently demonstrated a graphene-based high efficiency thermal-to-electricity conversion technology, called thermionic energy convertor. By using graphene as the anode, the efficiency of the device is increased by a factor of 6.7 compared with a traditional tungsten anode. This technology can work in a tandem cycle with existing thermal-based power plants and significantly improve their overall efficiencies.[img_assist|nid=4034|title=|desc=|link=none|align=center|width=400|height=188]Hongyuan Yuan and Roger T. Howe, among the leading researchers in the Stanford team, explain that one of the major challenges for wide adoption of TECs is high anode work function, which directly reduces the output voltage as well as the net efficiency. The theoretical maximum efficiency for a TEC with a 2 eV work function anode is 3% at a cathode temperature of 1500 K, compared to an astonishing 10-fold increment to 32% with a 1 eV work function anode.

Investigation of electronic, magnetic and thermoelectric properties of Zr2NiZ (Z = Al,Ga) ferromagnets

Publication date: 1 May 2017
Source:Materials Chemistry and Physics, Volume 192
Author(s): Saleem Yousuf, Dinesh C. Gupta
Systematic investigation of impact of electronic structure and magnetism, on the thermoelectric properties of new Zr2NiZ (Z = Al, Ga) Heusler alloys are determined using density functional theory calculations. Half-metallicity with ferromagnetic character is supported by their 100% spin polarisations at the Fermi level. Magnetic moment of ∼3 μB is according to the Slater-Puling rule, enables their practical applications. Electron density plots are used to analyse the nature of bonding and chemical composition. Boltzmann's theory is conveniently employed to investigate the thermoelectric properties of these compounds. The analysis of the thermal transport properties specifies the Seebeck coefficient as 25.6 μV/K and 18.6 μV/K at room temperature for Zr2NiAl and Zr2NiGa, respectively. The half-metallic nature with efficient thermoelectric coefficients suggests the likelihood of these materials to have application in designing spintronic devices and imminent thermoelectric materials.

BiCuSeO Thermoelectrics: An Update on Recent Progress and Perspective

BiCuSeO Thermoelectrics: An Update on Recent Progress and Perspective | Thermal to electric conversion | Scoop.it
A BiCuSeO system has been reported as a promising thermoelectric material and has attracted great attention in the thermoelectric community since 2010. Recently, several remarkable studies have been reported and the ZT of BiCuSeO was pushed to a higher level. It motivates us to systematically summarize the recent reports on the BiCuSeO system. In this short review, we start with several attempts to optimize thermoelectric properties of BiCuSeO. Then, we introduce several opinions to explore the origins of low thermal conductivity for BiCuSeO. Several approaches to enhance thermoelectric performance are also summarized, including modulation doping, introducing dual-vacancies, and dual-doping, etc. At last, we propose some possible strategies for enhancing thermoelectric performance of BiCuSeO in future research.

Patent CA2367686C - Hybrid thermionic energy converter and method

Patent CA2367686C - Hybrid thermionic energy converter and method | Thermal to electric conversion | Scoop.it
The present invention embodies a solid state thermionic energy converter and is directed to a method and apparatus (10, 104, 108) for conversion of thermal energy to electrical energy, and electrical energy to refrigeration. The present invention maintains a thermal separation between an emitter (12) and a collector (16) through a fractional surface contact (13, 42, 44) of decreasing cross-sectional area towards the point of contact. The fractional surface contacts (13, 42, 44) may be associated with the emitter (12), a barrier (14), or the collector (16). Maintaining a thermal separation between the emitter (12) and the collector (16) provides for ballistic electron transport through the barrier (14) and reduces the transport of electrons through thermal conductivity. Hence, the efficiency is increased through the collection of ballistic electrons and the reduction of thermal conductivity electrons which cannot be collected. The inventive principle works for hole conductivity, as well as for electrons.
