The same silicon-based technology that demands a wider array of voltages also makes it possible to save power with smart solid-state conversion circuits.
Thermoelectric materials have attracted interest because of the potential large benefits of solid-state conversion of waste heat to electricity [1, 2, 3, 4].
Re-oxidation would result in precipitation of either additional lepidocrocite or magnetite through reaction of aqueous 57Fe(II) rather than from solid-state conversion of lepidocrocite to magnetite.
In situ XANES has been used to monitor changes in oxidation state under electrochemical control that lead to a solid-state conversion or dissolution of metal or oxide.
The reduction of 57Fe(III) could result from reaction with 56Fe(II) via solid-state conversion of lepidocrocite to magnetite, which would result in the presence of magnetite spectral features in Mössbauer spectra.
Two chromite spinel-based composite materials, MnIICrIII2O4/MnIIMnIII2O4/C and CoCr2O4/C are successfully synthesized by a solid-state conversion process via annealing MnCr-coordination compound and CoCr-coordination compound at 350 °C in air for 1 h, respectively.
The fundamental concepts of the FFC-Cambridge-type electro-deoxidation cell for the solid-state conversion of metal oxides to metals are revisited and, based upon these, an expression is presented which describes the transport of oxide ions across the molten salt electrolyte.
Our results suggest a method for fabricating transparent oxide electron conductors with large, tunable work functions that could be of relevance in designing electrodes for solid state energy conversion technologies.
There is a growing interest in direct thermal-to-electric energy conversion using solid state devices such as thermophotovoltaic (TPV) generators.
III-V compound semiconductor nanowires (NWs) such as InN[1] and GaN[2, 3] NWs are currently being investigated in view of their potential application as nanoscale optoelectronic devices for solid state lighting and solar energy conversion.
Dry ice undergoes sublimation (direct conversion from a solid state into a gas), and if it is warmed rapidly, large amounts of CO2 are generated, which is especially dangerous in closed environments [7 9].
