Bright Monocompound Metal Halide Scintillator for Fast Neutron Radiography

open access: yesAdvanced Functional Materials, EarlyView.
Metal halide scintillator, tetraphenylphosphonium manganese bromide (TPP2MnBr4), provides a significant benefit for fast neutron imaging. A fourfold increase in efficiency over traditional zinc sulfide screens is achieved by efficiently utilizing neutron interactions within its homogeneous structure.

High‐Density Boron Nitride Nanotube Composites via Surfactant‐Stabilized Lyotropic Liquid Crystals for Enhanced Space Radiation Shielding

open access: yesAdvanced Functional Materials, EarlyView.
High‐density BNNT films, enabling mechanical robustness and high space radiation shielding effectiveness, are fabricated using surfactant‐stabilized BNNT liquid crystal. Simulations indicate that a 50 g cm−2 BNNT film can reduce radiation exposure by 56% compared to zero shielding, potentially doubling the duration of astronaut missions on the lunar ...

A three-dimensional hydrodynamical line profile analysis of iron lines and barium isotopes in HD140283 [PDF]

open access: yes, 2015
Heavy-elements, i.e. those beyond the iron peak, mostly form via two neutron capture processes: the s- and r-process. Metal-poor stars should contain fewer isotopes that form via the s-process, according to currently accepted theory. It has been shown in

Engineering Oxygen Vacancy in Support to Promote Activity of In2O3 Catalyst for CO2 Electroreduction to Formate

open access: yesAdvanced Functional Materials, EarlyView.
A novel approach by depositing In2O3 onto an oxygen vacancy (OV)‐enriched support, ceria‐zirconia solid solutions (CZ), to activate synergistic effects is proposed. The OV contributes greatly to the dissociation of H2O and further promotes the hydrogenation of adsorbed CO2 species.

Seasonal Diet Changes and Trophic Links of Cold-Water Fish (Coregonus albula) within a Northern Lake Ecosystem

open access: yesAnimals
The seasonal feeding patterns of the cold-adapted fish, Coregonus albula, are poorly studied in high-latitude lakes but could provide insight for predicting the effects of global warming.

Magnetic‐Field Dependent VB− Spin Decoherence in Hexagonal Boron Nitrides: A First‐Principles Study

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates the decoherence of the VB− defect in h‐BN under external magnetic fields using first‐principles quantum many‐body simulations. A transition boundary distinguishing distinct decoherence regimes is identified, with its dependence on isotopic composition.
