Recent Examples on the Web Now Toyota has developed its first modern BEV, using lithium-ion (rather than nickel-metal hydride), called the bZ4x. Jonathan M. Gitlin, Ars Technica, 19 May 2023 After the retraction by Physical Review Letters, most of the authors of the lutetium hydride paper...
Hydrides of boron, particularly diborane, are prepared by reacting an organic ester of boric acid with aluminium metal and hydrogen at elevated temperatures. Suitable esters are listed, examples being triphenyl borate, trimethyl borate, tri-(t-butyl) borate, tricyclohexyl borate, tribenzyl borate and...
There are two approaches to developing new hydrides to meet these requirements: (1) modifying the properties of known hydrides - examples based on the thermodynamics of solids are discussed in some detail; and (2) synthesizing new intermetallic-compound hydrides....
Examples Regioselective reduction of malic acid ester.[1] Diastereoselective reduction of a β-hydroxyketone using Me4NHB(OAc)3[2]: More diastereoselective than NaHB(OAc)3. One-step conversion of a nitrile into a Boc-protected amine[3a]: The combination of a Lewis acid and NaBH4can also redu...
The only known compound of sodium and hydrogen is archetypal ionic NaH. Application of high pressure is known to promote states with higher atomic coordination, but extensive searches for polyhydrides with unusual stoichiometry have had only limited succ
This has the theoretical advantage of enabling the molecular virial theorem to be satisfied and the practical advantage, as shown by some examples, of improving the agreement with experiment particularly for the lighter molecules. The calculation of the scale factor requires two more integrals but ...
The search for high-temperature superconductors has been focused on compounds containing a large fraction of hydrogen, such as SiH4(H2)2, CaH6 and KH6. Through a systematic investigation of yttrium hydrides at different hydrogen contents using an structu
In applying the disclosure of these examples, it should be kept clearly in mind that the examples are merely illustrative of the present invention and should not be construed as limiting the scope of the invention in any way as many variations and equivalents that are encompassed by the present...

As specific examples the Group VIII-A hydrides are discussed, including their application as laser active media. Principal advantages of noble gas hydrides are lack of a bound ground electronic state (comparable with excimers), for less corrosiveness than Group VIII-A halides (or fluorine ...
