Deuterium burning in objects forming via the core accretion scenario - Brown dwarfs or planets?

open access: yes, 2012
Aims. Our aim is to study deuterium burning in objects forming according to the core accretion scenario in the hot and cold start assumption and what minimum deuterium burning mass limit is found for these objects.

Experimental study of fusion neutron and proton yields produced by petawatt-laser-irradiated D2-3He or CD4-3He clustering gases [PDF]

open access: yes, 2013
We report on experiments in which the Texas Petawatt laser irradiated a mixture of deuterium or deuterated methane clusters and helium-3 gas, generating three types of nuclear fusion reactions: D(d, 3He)n, D(d, t)p and 3He(d, p)4He.

Deuterium trafficking, mitochondrial dysfunction, copper homeostasis, and neurodegenerative disease

open access: yesFrontiers in Molecular Biosciences
Deuterium is a natural heavy isotope of hydrogen, containing an extra neutron. Eukaryotic organisms have devised complex metabolic policies that restrict the amount of deuterium reaching the mitochondria, because it damages the ATPase pumps, leading to ...

Field desorption ion source development for neutron generators

open access: yes, 2008
A new approach to deuterium ion sources for deuterium-tritium neutron generators is being developed. The source is based upon the field desorption of deuterium from the surfaces of metal tips. Field desorption studies of microfabricated field emitter tip

Sertraline Treatment Can Mimic Niemann‐Pick Type C Biomarker Profile: A Diagnostic Pitfall

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Oxysterols (cholestane‐3β,5α,6β‐triol and 7‐ketocholesterol) and N‐palmitoyl‐O‐phosphocholineserine (PPCS) are sensitive biomarkers for Niemann‐Pick disease type C (NPC) screening. However, false‐positive results occur, with a biomarker profile suggestive of NPC despite the absence of pathogenic variants in genes involved in NPC or ...

The biological effects of deuterium present in food

open access: yesDiscover Food
We have evaluated the biological importance of deuterium in foods based on literature data. Deuterium is a stable isotope of hydrogen that occurs naturally in our environment and is specifically enriched in certain foods.

Quantification Challenges for Atom Probe Tomography of Hydrogen and Deuterium in Zircaloy-4 [PDF]

open access: yesMicroscopy and Microanalysis, 2018
Analysis and understanding of the role of hydrogen in metals is a significant challenge for the future of materials science, and this is a clear objective of recent work in the atom probe tomography (APT) community.

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Deuteron Photodissociation in Ultraperipheral Relativistic Heavy-Ion on Deuteron Collisions

open access: yes, 2003
In ultraperipheral relativistic deuteron on heavy-ion collisions, a photon emitted from the heavy nucleus may dissociate the deuterium ion. We find deuterium breakup cross sections of 1.38 barns for deuterium-gold collisions at a center of mass energy of

Scintillation efficiency of liquid argon in low energy neutron-argon scattering [PDF]

open access: yes, 2015
Experiments searching for weak interacting massive particles with noble gases such as liquid argon require very low detection thresholds for nuclear recoils.
