Modular Generation of Alkyl Selenyl Radicals for the Synthesis of Alkyl Selenides via a Mechanochemical Approach

Advanced Science, EarlyView.
We present a mechanochemical, radical‐mediated hydroselenation of alkenes under ambient conditions. This method modularly generates alkyl selenyl radicals from elemental selenium and alkyl (pseudo)halides, utilizing PhSiH3 and H2O as hydrogen atom donors, with the water likely originating from the air and/or trace water present in the reagents ...

Stable Isotopic Evidence of Paleorecharge in the Northern Gulf Coastal Plain (USA)

Hydrology
Stable isotope abundances (δ18O and δ2H) in regional aquifers can provide important paleoclimate information. However, identifying paleoclimate signals can be complicated by cross-formational mixing and, potentially, by isotopic diffusion between ...

6R/S-deutero-α-d-mannopyranoside 1-phosphate

Molbank, 2019
6R/S-deutero-α-d-mannopyranoside 1-phosphate was synthesised from a C6 aldehydic mannose thioglycoside donor in four steps. Using NaBD4 as the reductant, isotopic enrichment at C6 was achieved and the resultant C6-deuterated material was converted ...

A Comparison of Polarization Observables in Electron Scattering from the Proton and Deuteron

, 1997
Recoil proton polarization observables were measured for both the p($\vec {\rm e}$,e$^\prime\vec{\rm p}\,$) and d($\vec {\rm e}$,e$^\prime\vec{\rm p}\,)$n reactions at two values of Q$^2$ using a newly commissioned proton Focal Plane Polarimeter at the M.

Dynamic Covalent Networks of Molecular Clusters for Hard and Impact‐Resistant Glass with Feasible Processability

Advanced Science, EarlyView.
Molecular granular material glass is fabricated by crosslinking sub‐nm POSS clusters with dynamic borate ester bonding while the materials combine high transparency, modulus, and hardness with superior impact resistance and (re)processability, offering a promising strategy for creating robust yet highly processable organic glasses.

Deuterium retention in MeV self-implanted tungsten: Influence of damaging dose rate

, 2017
Recrystallized, polycrystalline tungsten was self-damaged by 20 MeV tungsten ions up to a calculated damage dose in the damage peak of 0.23 dpa. The time to acquire this dose and hence the average damaging dose rate was varied from 6 × 10 -3 to 4 × 10 -6
