Photochemical enrichment of deuterium in Titan's atmosphere: new insights from Cassini-Huygens [PDF]

open access: yes, 2008
Cassini-Huygens data are used to re-examine the potential sources of the D/H enhancement over solar, measured in methane, in Titan's atmosphere. Assuming that the system is closed with respect to carbon, the use of constraints from the Huygens probe for ...

Deuterium metabolic imaging (DMI) for MRI-based 3D mapping of metabolism in vivo

open access: yesScience 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 ...

What is the Total Deuterium Abundance in the Local Galactic Disk? [PDF]

open access: yes, 2006
Analyses of spectra obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite, together with spectra from the Copernicus and IMAPS instruments, reveal an unexplained very wide range in the observed deuterium/hydrogen (D/H) ratios for ...

Mapping of exogenous choline uptake and metabolism in rat glioblastoma using deuterium metabolic imaging (DMI)

open access: yesFrontiers in Cellular Neuroscience, 2023
IntroductionThere is a lack of robust metabolic imaging techniques that can be routinely applied to characterize lesions in patients with brain tumors. Here we explore in an animal model of glioblastoma the feasibility to detect uptake and metabolism of ...

Resonant $dd\mu$ Formation in Condensed Deuterium [PDF]

open access: yes, 2001
The rate of $dd\mu$ muonic molecule resonant formation in $d\mu$ atom collision with a condensed deuterium target is expressed in terms of a single-particle response function.

Understanding the chemical structure of carbon edge sites by using deuterium-labeled temperature-programmed desorption technique

open access: yes, 2020
A deuterium-labeled temperature-programmed desorption (TPD) technique was developed to accurately characterize functional groups on the surface of carbon-based materials.

Validation of deuterium incorporation against sterol balance for measurement of human cholesterol biosynthesis

open access: yesJournal of Lipid Research, 1998
To examine the validity of the deuterium (D) incorporation technique for measurement of human cholesterol synthesis rates, D uptake from D2O into cholesterol was compared to sterol balance in 13 subjects each under three controlled diet settings ...

D2-Filled Hollow-Core Fiber Gas Raman Laser at 2.15 μm

open access: yesPhotonics, 2022
Fiber lasers around 2 µm band have attractive applications, such as coherent detecting, material processing, pump source for mid-IR lasers based on nonlinear frequency shift, etc. Fiber gas Raman lasers (FGRLs) based on the stimulated Raman scattering of
