Metabolites, 2019 NADPH is the primary source of cellular reductant for biosynthesis, and strategies for increasing productivity via metabolic engineering need to take account of the requirement for reducing power.

Deuterium in the Solar System [PDF]
Highlights of Astronomy, 1992 AbstractValues of D/H measured in the methane on the giant planets and Titan indicate the presence of two distinct reservoirs of deuterium in the outer solar system. The dominant reservoir is in hydrogen gas, the second, multi-component reservoir is found in the hydrogen that is bound in condensed compounds. Both reservoirs appear to have originated in

Advanced Science, EarlyView.Through an amorphization strategy, the electronic structure of single‐atom Co is effectively modulated from a low spin state (Co‐CCN) to a high spin state (Co‐ACN). The rearrangement of the electronic configuration optimizes the d‐band center resulting in the selectivity of 1O2 with almost 100%.

Fresnel Diffraction in Deuterium [PDF]
Annals of Physics, 1971 Abstract In Glauber's theory of high energy scattering the wavefunction inside the nucleus is given by geometrical optics. The theory is extended to lower energies by incorporating the effects due to Fresnel diffraction, and applied to elastic and inelastic scattering off deuterium.

Advanced Science, EarlyView.The introduction of isolated LaOx species into Pt nanoclusters confined within the silicalite‐1 zeolite significantly enhanced the oxidative removal of hydrogen isotopes. Under reaction conditions of 50 °C and GHSV of 72,000 mL·g−1·h−1, the catalyst achieved an excellent H2 conversion efficiency of over 99%.

Corrections to deuterium hyperfine structure due to deuteron excitations
, 2003 We consider the corrections to deuterium hyperfine structure originating from the two-photon exchange between electron and deuteron, with the deuteron excitations in the intermediate states. In particular, the motion of the two intermediate nucleons as a

FRACTIONATION OF HEAVY HYDROGEN ISOTOPES IN DYNAMICAL SYSTEMS
Геохімія техногенезу, 2019 The possibility of using mineral adsorbents for cleaning the moderator of heavy water reactors from tritium is determined. Three dynamic systems have been created using montmorilonite, sepiolite and palygorskite clays, and zeolite (systems M-Z, S-Z and P-

Physical Review CAn extension to our previous study on nuclear parton distribution functions (nPDFs) [Kim and Miller, ] using light-front holographic quantum chromodynamics (LFHQCD) [Brodsky, de Teramond, Dosch, and Erlich, ] is presented. We apply the effects of nucleon motion inside the nucleus (Fermi motion/smearing) to deuterium, extending our deuterium nPDFs to ...
