Interlayer Hydrogen Recombination from Hydrogen Boride Nanosheets Elucidated by Isotope Labeling.

In this study, deuterium boride (DB) nanosheets were synthesized as deuterated borophane through the ion exchange of magnesium cations in magnesium diboride with deuterons from a deuterium-type ion-exchange resin in acetonitrile. The Fourier-transform infrared absorption spectrum of DB exhibited clear isotope effects, namely the shift in the absorption peak of the B-H stretching vibrational mode to a lower wavenumber. Temperature-programmed desorption (TPD) from a mixture of DB and hydrogen boride (HB) nanosheets yielded a more intense hydrogen-deuterium (HD) signal compared to the H and D signals.

Value Effect of Health and Productivity Management: An Event Study of the HPM Award in Japan.

Objective: The value effect of winning the health and productivity management (HPM) award on their stock prices is to be evaluated.

Methods: An event study and an evaluation of portfolio over the first-time HPM awardees were conducted.

Results: The abnormal return (AR) of all the first-time HPM awardees was significantly positive (0.

Soluble sugar availability of aerobically germinated barley, oat and rice coleoptiles in anoxia.

Physiological and metabolic responses to anoxia were compared for aerobically germinated seedlings of barley (Hordeum vulgare), oat (Avena sativa) and rice (Oryza sativa). Coleoptile growth of barley, oat and rice seedlings was suppressed by a 24 h-anoxic stress, but the growth of the rice coleoptiles was much greater than that of the barley and oat coleoptiles. ATP concentration in the anoxic rice coleoptiles was greater than that in the anoxic barley and oat coleoptiles.

Effect of low temperature on ethanolic fermentation in rice seedlings.

Rice seedlings (Oryza sativa L.) were incubated at 5-30 degrees C for 48 h and the effect of temperature on ethanolic fermentation in the seedlings was investigated in terms of low-temperature adaptation. Activities of alcohol dehydrogenase (ADH, EC 1.
