Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing

Advanced Materials, EarlyView.
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

ON THE RELATIONSHIP BETWEEN AMBIENT DOSE EQUIVALENT AND ABSORBED DOSE IN AIR IN THE CASE OF LARGE-SCALE CONTAMINATION OF THE ENVIRONMENT BY RADIOACTIVE CESIUM

Радиационная гигиена, 2015
One of the main aims of the study was an experimental determination of the conversion coefficient from ambient dose equivalent rate, Н*(10), to absorbed dose rate in air, D, in the case of radioactive contamination of the environment following the ...

Structure shielding of school and gymnasium buildings against fallout gamma radiation from the Fukushima Daiichi Nuclear Power Plant accident

Ecotoxicology and Environmental Safety
The radiation dose reduction factor represents a building’s shielding capability against radiation in scenarios of potential nuclear accidents. Notably, the radiation dose reduction for school buildings and gymnasiums have not yet been determined, even ...

The stability and Quality Control of Instruments for Measurement of Ambient Dose Equivalent Rate

, 2022
Dosimeters for ambient dose equivalent rate monitoring used in Radiation and Environmental Protection Department in the Institute for Nuclear Sciences Vinča, аre made inhouse and they are readily exploited in the field work. Due to this and due to the nature of the measurement itself, quality control of these instruments is readily performed, at least ...

De Rerum Natura: How Do Halide Perovskites Self‐Heal From Damage?

Advanced Materials, EarlyView.
How can lead‐halide‐perovskites self‐heal after damage from light, heat, mechanical strain, or radiation? We show that reversible chemical defects underly performance losses and recovery, highlighting the roles of halide and proton migration, redox‐driven reactions, and acid‐base equilibria.

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

Advanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...
