We have measured the survival probability of H2 in a single rovibrational state (v=1,J=1) scattering from a Cu(110) surface at 78 meV translational energy, using molecular beam and laser state preparation techniques. The integrated survival probability is found to be only 0.74±0.13, compared...

The magnitude of the temperature dependence was found to be related to the concentration of molecules in the rotational J =1 state. The dielectric constant of HD was found to change quite dramatically between 1 and 2 K, while H 2 and D 2 show no similar change. 展开 ...
The terms “Innate immune memory” and “trained immunity” are used interchangeably herein and refer to the ability of innate immune cells to functionally reprogram after exogenous or endogenous insults and to respond non-specifically to a subsequent challenge after return to a non-activated state....
(LPAI), whereas 9% of examined poultry had elevated antibodies to the novel virus. However, the serological finding might be explained by antibodies against other H2 viruses such as H2N929, H2N730and H2N3 which have also been rarely found to circulate among ducks in Asia. No matter the H2...

Direct ways range from H2 absorption in the UV domain to detection of the radio hyperfine structure: the ortho-H2 molecule has an hyperfine, or ultrafine, structure in its fundamental state, due to the coupling between the rotation-induced magnetic moment, and the nuclear spin. This gives rise...

This has been enabled by the perfectly reversible H2 passivation of Pb, which affects the defect's spin state. Sequential hydrogenation at 253–353°C and degassing treatments in high vacuum at 743–835°C allowed to vary the Pb density in the range 5 × 1010 < [Pb] ⩽ (1.14 ± 0.06...
