Superconducting Binary Hydrides: Theoretical Predictions and Experimental Progresses
Hydrogen, the lightest element in the periodic table, has been predicted to metalize under extreme compression. Metallic hydrogen is believed to be a room-temperature superconductor.

EFFECT OF HEAT TREATMENT ON HYDROGEN SOLUBILITY IN Zr-2.5Nb ALLOY
We have studied the hydrogen terminal solid solubility (TSS) on Zr-2.5Nb. The samples were aged at 470◦C for 10h, plus a hydrogen gaseous charge followed by a homogenization treatment at 470◦C - 6 h in order of distributing the hydrogen throughout the ...

Superconducting Hydrides Under Pressure [PDF]
The measurement of superconductivity at above 200K in compressed samples of hydrogen sulfide and lanthanum hydride at 250K is reinvigorating the search for conventional high temperature superconductors. At the same time it exposes a fascinating interplay

Mechanical Properties Degradation at Room Temperature in ZRY-4 by Hydrogen Brittleness
A hot rolled Zircaloy-4 alloy, annealed with a final cold rolling, presenting rounded grains, was studied. Hydrogen cathodic charge with a homogenization heat treatment was used to pre-charge the specimens with different hydrogen contents.

A New Complex Borohydride LiAl(BH4)2Cl2
A new mixed alkali metal–aluminum borohydride LiAl(BH4)2Cl2 has been prepared via mechanochemical synthesis from the 2LiBH4–AlCl3 mixture. Structural characterization, performed using a combination of X-ray powder diffraction and solid-state NMR methods,
