Deuterium metabolic imaging (DMI) for MRI-based 3D mapping of metabolism in vivo
Science Advances, 2018 DMI shows metabolism of acetate and glucose in the brain and liver and reveals the Warburg effect in patients with brain tumors. Currently, the only widely available metabolic imaging technique in the clinic is positron emission tomography (PET ...

Analysis of lattice locations of deuterium in tungsten and its application for predicting deuterium trapping conditions [PDF]
arXiv, 2023 Retention of hydrogen isotopes (protium, deuterium and tritium) in tungsten is one of the most severe issues in design of fusion power plants, since significant trapping of tritium may cause exceeding radioactivity safety limits in future reactors. Hydrogen isotopes in tungsten can be detected using the nuclear reaction analysis method in channeling ...

Highly spin-polarized deuterium atoms from the UV dissociation of Deuterium Iodide [PDF]
Phys. Rev. Lett. 118, 233401 (2017), 2016 We report the production of highly spin-polarized Deuterium atoms via photodissociation of deuterium iodide at 270 nm. The velocity distribution of both the deuterium and iodine photodissociation products is performed via velocity mapping slice-imaging. Additionally, the angular momentum polarization of the iodine products is studied using polarization-

Gate Oxide Reliability and Deuterated CMOS Processing [PDF]
, 2004 In recent literature, a controversy has arisen over the question whether deuterium improves the stability of the MOS gate dielectric. It appears as if this controversy finds its origin in the different stages (e.g.

Revista Facultad de Ingeniería, 2018 Identifying the hydraulic connection between the area of recharge and the area of discharge in aquifers is only possible by using tracers; the 18O and 2H isotopes have proven to be good tracers to determine such hydraulic connection.

H-D Substitution in Interstellar Solid Methanol: A Key Route for D Enrichment [PDF]
Astrophys.J. 624 (2005) L29-L32, 2005 Deuterium enrichment of interstellar methanol is reproduced experimentally for the first time via grain-surface H-D substitution in solid methanol at an atomic D/H ratio of 0.1. Although previous gas-grain models successfully reproduce the deuterium enrichments observed in interstellar methanol molecules (D/H of up to 0.4, compared to the cosmic ratio ...

Spectral tracing of deuterium for imaging glucose metabolism
Nature Biomedical Engineering, 2019 Cells and tissues often display pronounced spatial and dynamical metabolic heterogeneity. Common glucose-imaging techniques report glucose uptake or catabolism activity, yet do not trace the functional utilization of glucose-derived anabolic products ...

A field evaporation deuterium ion source for neutron generators [PDF]
J.Appl.Phys.103:094912,2008, 2008 Proof-of-principle experiments have demonstrated an electrostatic field evaporation based deuterium ion source for use in compact, high-output deuterium-tritium neutron generators. The ion source produces principally atomic deuterium and titanium ions.
