Protection from contamination by 211At, an enigmatic but promising alpha-particle-emitting radionuclide

EJNMMI Physics, 2022
Purpose 211At, a promising alpha-particle-emitting radionuclide, can easily volatilize and contaminate the environment. To safely manage this unique alpha-particle-emitting radionuclide, we investigated the permeability of four types of plastic films and

Investigation of Moisture‐Induced Degradation Mechanisms and a Reviving Strategy for Sulfide‐Based Solid Electrolytes in All‐Solid‐State Composite Cathode

Advanced Energy Materials, EarlyView.
Moisture exposure induces the formation of reductive solid phases on argyrodite Li6PS5Cl, which destabilize Ni‐rich cathodes by extracting lattice oxygen and inducing surface reconstruction. A brief oxygen‐assisted annealing treatment quenches these reductive phases, restores interfacial stability, and enables effective regeneration and reuse of ...

Paradigm shift in wearable bioelectronics: Drift‐free organic field‐effect transistor biosensors enabled by diode‐connected pairs

BMEMat, EarlyView.
Organic field‐effect transistor (OFET)‐based biosensors are promising for wearable technology due to their flexibility and low cost, but their susceptibility to signal drift from mechanical stress and environmental factors remains a challenge. Here, we highlight a novel strategy that eliminates these drifts through a fundamental redesign of the OFET ...

Swelling Effect of Liquids on NBR (Nitrile Rubber)

, 1961
Immersion tests in various polar and nonpolar solvents have been undertaken with a range of butadiene-acrylonitrile copolymers. For a particular liquid, it would appear that the volume change can be related to the acrylonitrile content of the rubber' by ...

Diastereoselective Copper‐Catalyzed Defluorosilylation of Pentafluoroethyl Alkenes to Access Polyfluorinated Allylsilanes

Chinese Journal of Chemistry, EarlyView.
Under copper(I) catalysis, pentafluoroethylated alkenes can undergo smooth defluorosilylation to generate novel polyfluorinated products. The reaction exhibits high levels of diastereoselectivities for obtaining multisubstituted allylsilanes with control of the double bond geometry.

The Latest Trend of Nitrile Rubber

NIPPON GOMU KYOKAISHI, 2005
Acrylonitrile-butadiene rubbers (NBR) and hydrogenated crylonitrile-butadiene rubbers (HNBR) have been widely used as oil-resistant elastomers especially in automotive applications. The history of NBR is very old and has ripened as technology. However, the needs to NBR still continue, such as enhance durability, reduce environmental damage, and our ...
