Pd–Ag alloys are largely used as hydrogen separation membranes and, a consequence, the Pd–Ag–H system has been intensively studied. On contrary, fewer information is available for Pd–Ag–D system; thus, aim of this work to improve knowledge isotope effect on commercial Pd77Ag23 alloy, especially temperature above 200 °C. In particular, deuterium absorption measurements carried out in alloy range...

With the increasing importance of “ heavy water” as a moderator in nuclear reactors there arises a pressing need for a more efficient method of separating hydrogen isotopes. In a report by 0. N. Salmon to the U.S. Atomic Energy Commission (AEC Research and Development Report KAPL 1272) a process is described which aims to improve the method of separation by the electrolysis of water. This proce...

Graphdiyne, a recently synthesized one-atom-thick carbon allotrope, is atomistically porous - characterized by a regular "nanomesh"- and suggests application as a separation membrane for hydrogen purification. Here we report a full atomistic reactive molecular dynamics investigation to determine the selective diffusion properties of hydrogen (H(2)) amongst carbon monoxide (CO) and methane (CH(4...

Exfoliation of SiC by hydrogen implantation and subsequent annealing forms the basis for a thi n-fiim separation process ~vhichqwhen combined with hydrophilic wafer bonding. can be exploited to produce siIicon-carbide-cm-insulator, SiCOI. Sic thin films produced by this process exhibit unacceptably high resistivity because defects generated by the implant neutralize electrical carriers. Separat...

The title compound, C15H12N4O, adopts an E conformation with respect to the azomethine bond and crystallizes in its hydrazinyl-idene tautomeric form. The dihedral angle between the ring systems is 15.98 (7)°. The phenol O-H group forms an intra-molecular O-H⋯N hydrogen bond. In the crystal, pairs of N-H⋯N and C-H⋯O hydrogen bonds link neighbouring mol-ecules into centrosymmetric dimers. These d...

In this work, a molecular dynamics simulation of the transport of water - methanol mixture through the single wall carbon nanotube (SWCNT) is reported. Methanol and water are selected as fluid molecules since water represents a strongly polar molecule while methanol is as an intermediate between polar and strongly polar molecules. Some physical properties of the methanol-water mixture such as r...
