To shred roughly or to grind? On the methods of sample preparation of the keratinous material for stable hydrogen isotope analysis

open access: yesТрансформация экосистем, 2020
Hydrogen stable isotope measurement in keratin samples (hair, feathers, etc.) is one of the very popular, but rather complex tasks of isotope ratio mass spectrometry.

Stem water cryogenic extraction biases estimation in deuterium isotope composition of plant source water

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance Stem xylem uptake and transport of plant source water is widely considered a critical component of the global water cycle. The deuterium signature of cryogenically extracted plant stem water (δ2Hstem_CVD) provides a useful means for studying

One Percent Determination of the Primordial Deuterium Abundance [PDF]

open access: yes, 2017
We report a reanalysis of a near-pristine absorption system, located at a redshift toward the quasar Q1243+307, based on the combination of archival and new data obtained with the HIRES echelle spectrograph on the Keck telescope.

The Impact of Deuterated CMOS processing on Gate Oxide Reliability [PDF]

open access: yes, 2005
In recent literature, a controversy has arisen over the question whether deuterium improves the stability of the MOS gate dielectric. In particular, the influence of deuterium incorporation on the bulk oxide quality is not clear.

Enhanced anti-deuteron Dark Matter signal and the implications of PAMELA [PDF]

open access: yes, 2009
We show that the jet structure of DM annihilation or decay products enhances the anti-deuterium production rate by orders of magnitude compared to the previous computations done assuming a spherically symmetric coalescence model.

Deuterium- and Tritium-Labelled Compounds: Applications in the Life Sciences.

open access: yesAngewandte Chemie, 2018
Hydrogen isotopes are unique tools for identifying and understanding biological and chemical processes. Hydrogen isotope labelling allows for the traceless and direct incorporation of an additional mass or radioactive tag into an organic molecule with ...

Comparison Study of the Metabolic Characteristics of Three Kinds of Deuterium-labeled Glucose in Rat Glioma Cells

open access: yesChinese Journal of Magnetic Resonance, 2023
Deuterium (2H) magnetic resonance imaging is an emerging molecular metabolic imaging method that can visualize the metabolic pathway in vivo, and therefore has great potential in clinical applications such as cancer detection.
