Is Deuterium Sequestering by Reactive Carbon Atoms an Important Mechanism to Reduce Deuterium Content in Biological Water? [PDF]

FASEB BioAdvances
Deuterium is a natural heavy isotope of hydrogen, having a neutron as well as a proton. Deuterium disrupts ATP synthesis in mitochondria, causing increased production of reactive oxygen species and reduced synthesis of ATP.

On the Use of Stable Hydrogen Isotope Measurements (δ²H) to Discern Trophic Level in Avian Terrestrial Food Webs

Diversity, 2021
The measurement of stable hydrogen isotope ratios (δ2H) in animal tissues is a popular means of inferring spatial origins and migratory connections. However, the use of this isotope to infer diet and potentially trophic position remains poorly understood,

To Divide or Not to Divide? How Deuterium Affects Growth and Division of Chlamydomonas reinhardtii

Biomolecules, 2021
Extensive in vivo replacement of hydrogen by deuterium, a stable isotope of hydrogen, induces a distinct stress response, reduces cell growth and impairs cell division in various organisms.

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

Трансформация 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.

Cosmological Deuterium Production in Non-Standard Scenarios [PDF]

, 2002
It is widely believed that the cosmic baryon density may be obtained by inferring deuterium abundances in low-metallicity quasar absorption line systems. The implicit assumptions which enter this argument are critically assessed.

On the deuterium abundance and the importance of stellar mass loss in the interstellar and intergalactic medium [PDF]

, 2018
We quantify the gas-phase abundance of deuterium and fractional contribution of stellar mass loss to the gas in cosmological zoom-in simulations from the Feedback In Realistic Environments project.

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

, 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.

Signal Processing for the Measurement of the Deuterium/Hydrogen Ratio in the Local Interstellar Medium

Entropy, 2014
We report on a comprehensive signal processing procedure for very low signal levels for the measurement of neutral deuterium in the local interstellar medium from a spacecraft in Earth orbit.

Probing the effectiveness: chiral perturbation theory calculations of low-energy electromagnetic reactions on deuterium [PDF]

, 2001
I summarize three recent calculations of electromagnetic reactions on deuterium in chiral perturbation theory. All of these calculations were carried out to O(Q^4), i.e. next-to-next-to-leading order.
