Exploring Infant Size and Body Composition at 18 Months: An Ambidirectional Peri‐Urban South African Cohort Study

open access: yesMaternal and Child Nutrition
The first 1000 days of life lay the foundations for subsequent growth. This ambidirectional study, including prenatal, perinatal and postnatal factors, aimed to identify exposure variables affecting body size and composition and corresponding Z‐score ...

A NOTE ON THE SPECIFIC HEATS OF LIQUID DEUTERIUM OXIDE

open access: yes, 1935
Preliminary determinations of the specific heats of liquid deuterium oxide from 4° to 65 °C. are described. The average specific heats over the temperature ranges 4° to 26 °C., 26° to 45 °C., and 26° to 65 °C., are 1.018, 1.003 and 1.008 respectively ...

Studies on induction of mutations by chemicals. I. Experiments with heavy water (deuterium oxide)

open access: yes, 1943
Heavy water (deuterium oxide) was introduced into Drosophila eggs and larvae by feeding and by injections. Owing to the high permeability of the cell membranes, similar to the permeability for pure water, it is very likely that deuterium was utilized in ...

Deprotective Alkylation: A Platform for Alcohol‐to‐Amine Interconversion Using Nonafluoromesitylenesulfonamides

open access: yesAngewandte Chemie International Edition, EarlyView.
The straightforward conversion of alcohols to tertiary or secondary amines employing Nms‐amides in a single operation is described. The transformation features broad functional group tolerance and high stereospecificity, underscoring its utility in the synthesis of isotope‐labeled pharmaceuticals.

Insight into the Mechanism of the Thermal Reduction of Graphite Oxide: Deuterium-Labeled Graphite Oxide Is the Key

open access: yes, 2015
For the past decade, researchers have been trying to understand the mechanism of the thermal reduction of graphite oxide. Because deuterium is widely used as a marker in various organic reactions, we wondered if deuterium-labeled graphite oxide could be ...

Dielectric constant of deuterium oxide

open access: yesJournal of Research of the National Bureau of Standards, 1958
An equal ratio-arm, capacitance-conductance bridge operated at frequencies below 100 kc was used to measure the dielectric constant of deuterium oxide with an accuracy of 0.1% or better in the range 4 to 100 deg C. A value of 77.94 was found for the dielectric constant at 25 deg C. The data fit the relation epsilon = 87.48/sub 2/ -- (0.40509)t + (9.638

Deuterium Labelling of L-Tyrosine with Raney Alloys in Alkaline Deuterium Oxide Solutions

open access: yes
The synthesis of deuteriated L-tyrosines with Raney alloys in alkaline deuterium oxide solutions, involving reductive debromination of brominated L-tyrosines and hydrogen-deuterium (H-D) exchange of L-tyrosines, without causing racemization, is ...

Oxygen annealing for deuterium doped indium tin oxide thin films [PDF]

open access: yes
Deuterium-doped indium tin oxide films, fabricated by dc plasma deposition in sputter gas consisting of deuterium and argon, were annealed at 300 °C for 40 min in flowing oxygen gas by using tubular gold image furnace.
