  2. Hydride vapour-phase epitaxy - Wikipedia

    en.wikipedia.org/wiki/Hydride_vapour-phase_epitaxy

    Hydride vapour-phase epitaxy (HVPE) is an epitaxial growth technique often employed to produce semiconductors such as GaN, GaAs, InP and their related compounds, in which hydrogen chloride is reacted at elevated temperature with the group-III metals to produce gaseous metal chlorides, which then react with ammonia to produce the group-III nitrides.

  3. Hydride - Wikipedia

    en.wikipedia.org/wiki/Hydride

    The hydride reacts with the weak Bronsted acid releasing H 2. Hydrides such as calcium hydride are used as desiccants, i.e. drying agents, to remove trace water from organic solvents. The hydride reacts with water forming hydrogen and hydroxide salt. The dry solvent can then be distilled or vacuum transferred from the "solvent pot".

  4. Hydrogen anion - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_anion

    The hydrogen anion is the dominant bound-free opacity source at visible and near-infrared wavelengths in the atmospheres of stars like the Sun and cooler; [2] its importance was first noted in the 1930s. [3] The ion absorbs photons with energies in the range 0.75–4.0 eV, which ranges from the infrared into the visible spectrum.

  5. Hydride compressor - Wikipedia

    en.wikipedia.org/wiki/Hydride_compressor

    A hydride compressor is a hydrogen compressor based on metal hydrides with absorption of hydrogen at low pressure, releasing heat, and desorption of hydrogen at high pressure, absorbing heat, by raising the temperature with an external heat source like a heated waterbed or electric coil. [1] [2] [3] [4]

  6. Transition metal hydride - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_hydride

    A metal hydride can be a thermodynamically a weak acid and a weak H − donor; it could also be strong in one category but not the other or strong in both. The H − strength of a hydride also known as its hydride donor ability or hydricity corresponds to the hydride's Lewis base strength. Not all hydrides are powerful Lewis bases.

  7. Binary compounds of hydrogen - Wikipedia

    en.wikipedia.org/wiki/Binary_compounds_of_hydrogen

    Binary hydrogen compounds in group 1 are the ionic hydrides (also called saline hydrides) wherein hydrogen is bound electrostatically. Because hydrogen is located somewhat centrally in an electronegative sense, it is necessary for the counterion to be exceptionally electropositive for the hydride to possibly be accurately described as truly behaving ionic.

  8. Hydride selenide - Wikipedia

    en.wikipedia.org/wiki/Hydride_selenide

    Salt-like hydride selenides may be formed by heating selenium with a metal hydride in an oxygen-free capsule. For rare earth elements, this method works as long as selenium has enough oxidising power to convert a +2 oxidation state to a +3 state. So for europium and ytterbium it does not work as the monoselenide is more stable. [1]

  9. Flavin adenine dinucleotide - Wikipedia

    en.wikipedia.org/wiki/Flavin_adenine_dinucleotide

    FAD is the more complex and abundant form of flavin and is reported to bind to 75% of the total flavoproteome [16] and 84% of human encoded flavoproteins. [17] Cellular concentrations of free or non-covalently bound flavins in a variety of cultured mammalian cell lines were reported for FAD (2.2-17.0 amol/cell) and FMN (0.46-3.4 amol/cell). [18]
