Influence of the presence of deuterium on displacement damage in tungsten

Nuclear Materials and Energy, 2018
The influence of the presence of deuterium on displacement damage in tungsten is studied by implanting 20 MeV tungsten ions into displacement-damaged tungsten already containing 1.7 at.% deuterium.

Structure–property relationships of reduced graphene oxide membranes intercalated with polycyclic aromatics

AIChE Journal, EarlyView.
Abstract Graphene oxide (GO) membranes intercalated with various organic moieties have shown excellent potential for a range of water processing applications. However, microstructure–functional property relationships in these structurally disordered membranes are not well understood.

Unlocking Lactonase Enzymes as Biocatalysts for the Deracemisation of Chiral γ‐Thiolactones

Angewandte Chemie, EarlyView.
The application of lactonase enzymes as biocatalysts still remains underexplored. This study discloses the biocatalytic activity of two lactonases in the deracemisation of chiral C3‐substituted‐γ‐thiolactones. The biocatalyst GcL catalyses the enzymatic kinetic resolution (EKR) of C3‐amide‐thiolactones, while the rationally engineered biocatalyst N9 ...

Artificial Intelligence‐Assisted Target Design for High‐Intensity Laser‐Driven Neutron Sources

Advanced Intelligent Systems, EarlyView.
This study presents an artificial intelligence (AI)‐assisted target design that combines particle‐in‐cell simulations with gradient ascent algorithm to optimize laser‐driven neutron sources. By enhancing the sheath electric field, the optimized structure increases neutron yield by a factor of 4,000.

Varying leptonic chemical potentials and spatial variation of primordial deuterium at high z

, 1997
We try to explain the spatial variation of primordial deuterium suggested by some observations by varying leptonic chemical potentials. The variation of the latter may take place in some scenarios of leptogenesis. The model predicts a large mass fraction

Access to N‐Monofluoromethylated (Thio)Carbamates, Formamides, Alkynamides, and Related Derivatives

Angewandte Chemie, EarlyView.
The first general synthetic access to N‐CH₂F and N‐CHRF carbamates, thiocarbamates, formamides, alkynamides, and related compounds is disclosed. The method involves the direct synthesis of carbamoyl fluoride building blocks from readily available amines, followed by their derivatization. Abstract This work presents the first general synthetic access to

Measuring deuterium permeation through tungsten near room temperature under plasma loading using a getter layer and ion-beam based detection

Nuclear Materials and Energy, 2017
A method to measure deuterium permeation through tungsten near room temperature under plasma loading is presented. The permeating deuterium is accumulated in a getter layer of zirconium, titanium or erbium, respectively, on the unexposed side of the ...

[2H26]-1-epi-Cubenol, a completely deuterated natural product from Streptomyces griseus

Beilstein Journal of Organic Chemistry, 2013
During growth on fully deuterated medium the volatile terpene [2H26]-1-epi-cubenol was released by the actinomycete Streptomyces griseus. This compound represents the first completely deuterated terpene obtained by fermentation.
