Monitoring dynamic changes and process in eco-environment by applying hydrogen and oxygen isotopes: a review [PDF]

, 2013
The hydrological cycle, or water cycle, embraces and connects all forms of water-related processes in the atmosphere and geosphere, which include water as vapour in, and precipitation from, the atmosphere, and in rivers, lakes, runoff, soil water, and ...

Spectroscopy of superheavy hydrogen isotopes [PDF]

, 2005
The superheavy hydrogen isotopes 4H and 5H have been investigated in the stopped pion absorption on 9Be. Three states of 4H were proposed in the reaction channel 9Be( π{ - }, dt)X. Four states of 5H were proposed in the reaction channels 9Be(π{ - }, pt)X

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Molecular Sieves for the Separation of Hydrogen Isotopes [PDF]

, 2020
Stable molecular hydrogen isotopes, D and T, are both scarce and essential in several energy, industrial, and large-scale fundamental research applications. Due to the chemical similarity of these isotopes, their extraction and purification from hydrogen

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Irradiation‐Induced Spin Bath Evolution and as‐Grown Hydrogen Defects in CVD Diamond Revealed by NV‐Based DEER Spectroscopy

Advanced Functional Materials, EarlyView.
Here, we provide the reader with the current state of the art in the fabrication of high‐T2‐coherence diamond, optimized through the use of double electron–electron resonance (DEER) spectroscopy. We reveal the main as well as yet unidentified spin defects, the reduction of which is essential for reducing the spin bath and fabricating materials for ...

Exploring methane cycling in an arctic lake in Kangerlussuaq Greenland using stable isotopes and 16S rRNA gene sequencing

Frontiers in Environmental Science, 2022
Lakes are currently responsible for a significant amount of total natural methane emission. Microbial oxidation of methane plays a central role in Arctic carbon cycling, potentially reducing methane emissions from lakes, though little is known about ...
