Hydro- and deutero-deamination of primary amines using O-diphenylphosphinylhydroxylamine

Nature Communications
While selective defunctionalizations are valuable in organic synthesis, hydrodeamination of primary amines poses challenges. Deuterodeamination, analogous to hydrodeamination, presents even greater difficulties due to its frequently slower deuteration ...

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

, 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 ...

Insights from quasi-in situ cryogenic-transfer atom probe tomography for analyzing hydrogen diffusion in metallic alloys

npj Materials Degradation
Understanding hydrogen embrittlement mechanisms requires insights into nanoscale hydrogen isotope segregation in materials. Cryogenic-transfer atom probe tomography (APT) can provide this insight, if the sample exposure is precisely controlled. Therefore,

New insight into 3-picoline—deuterium oxide (D2O) mixtures of limited miscibility with the lower critical consolute temperature

Results of phase equilibria studies of 3-picoline—deuterium oxide mixtures of limited miscibility. Studies were focused on showing the violation of Cailletet-Mathias law of rectilinear diameter for the lower critical consolute temperature mixtures of ...

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

, 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 ...

A millifluidic calorimeter with InfraRed thermography for the measurement of chemical reaction enthalpy and kinetics [PDF]

, 2008
The aim of this work is to present an infrared calorimeter for the measurement of the kinetics and the enthalpy of high exothermic chemical reactions. The main idea is to use a millifluidic chip where the channel acts as a chemical reactor.

Proteomics and lipids of lipoproteins isolated at low salt concentrations in D2O/sucrose or in KBr

Journal of Lipid Research, 2008
There is much interest in the significance of apolipoproteins and proteins that are noncovalently associated with lipoproteins. It is possible that the high ionic strength used for isolation of lipoproteins with KBr and NaI could alter the pattern of ...
