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.

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

Proceedings 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

A new tension in the cosmological model from primordial deuterium?

, 2021
Recent measurements of the D(p,$\gamma)^3$He, nuclear reaction cross-section and of the neutron lifetime, along with the reevaluation of the cosmological baryon abundance from cosmic microwave background (CMB) analysis, call for an update of abundance ...

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.

First GD-OES results on various deuterium ion fluences implanted in tungsten

Nuclear Materials and Energy, 2018
Glow discharge optical emission spectroscopy (GD-OES) was used to investigate the deep depth profile of deuterium in tungsten exposed to deuterium ions at various fluences. Deuterium was found to continue to decrease in intensity at depths 10–20 µm, even

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,

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.

Tracking The Post-BBN Evolution Of Deuterium [PDF]

, 2009
The primordial abundance of deuterium produced during Big Bang Nucleosynthesis (BBN) depends sensitively on the universal ratio of baryons to photons, an important cosmological parameter probed independently by the Cosmic Microwave Background (CMB ...

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.
