Advanced Functional Materials, EarlyView.A nanostructured palladium membrane is developed for high‐temperature hydrogen separation, comprising isolated, thermally‐stable palladium plugs embedded within nanopores of a porous support. The membrane withstands high temperatures (1000 K for 100 h) without structural failure, demonstrating exceptional robustness over conventional metal membranes ...

Nuclear reactions in shock wave front during supernova events [PDF]
The new unique isotopic anomalous coponent of Xe(XeX) was found in the carbonaceous chondrites. It is enriched in light shielded isotopes (124Xe and 126Xe) and in heavy nonshielded isotopes (134Xe and 136Xe.

Nitrogen isotope analysis of ammonium and glycine [PDF]
, 2005 Stable isotope techniques can be used as a tool in nitrogen cycling studies of different ecosystems. The studies are based on measurement of the heavy (15N)- to- light (14N) isotopic ratios of nitrogen in different biospheric pools.

Eos, Transactions American Geophysical Union, 1983 Diamond crystals may contain useful geochemical evidence of the deep portions of the upper mantle in their carbon isotopes. Two recent studies of types I and II diamonds showed that variations in δ13C may be related to carbon reservoir sources in the mantle (Nature, 303, 791–792, and 793–795, 1983).

Advanced Functional Materials, EarlyView.The pyrene and ether groups are incorporated into the covalent triazine polymer (CTP) structure. The synergistic effect of the two functional groups endows CTP with better electron transfer, light absorption, and oxygen activation properties. An impressive apparent quantum yield (13.2% @420 nm) and a remarkable solar‐to‐chemical conversion efficiency ...

A light carbon isotope composition for the Sun
Nature Communications, 2018 AbstractMeasurements by the Genesis mission have shown that solar wind oxygen is depleted in the rare isotopes, 17O and 18O, by approximately 80 and 100‰, respectively, relative to Earth’s oceans, with inferred photospheric values of about −60‰ for both isotopes.

Advanced Functional Materials, EarlyView.An advanced F‐doped and ─CN group co‐modified FCCN is developed. Due to the synergistic effects of co‐modification in promoting photogenerated exciton generation, enhancing charge kinetics, expanding active interfacial areas, and optimizing CO2 interfacial reactions, the FCCN photocatalyst demonstrates excellent catalytic performance and high ...
