some organic molecules can be isomerized upon photoirradiation and when accompanied by a change in the visible absorption spectrum, it is called photochromism. azobenzenes are important part of molecular machines and nanotechnology, which are this phenomenon is called photoisomerization azobenzene (azo) chromophores , and have been incorporated into a wide variety of materials and molecular arc...

A multi component AB 2 type hydrogen storage intermetallic alloy (A = Ti 0.85 Zr 0.15 , B Mn 1.22 Ni 0.22 Cr 0.2 V 0.3 Fe 0.06 ; was investigated in this work. The specified above modified by oxygen to yield the composition O 0.05 . introduced adding TiO charge, with corresponding decrease of amount, followed arc melting and annealing at same conditions as for free -type alloy. addition did not...
