High‐Sensitivity Perovskite γ‐Ray Detectors Enhanced by Device Engineering Toward Energy Spectroscopy Imaging

Advanced Science, EarlyView.
Optimized electrode configuration in perovskite γ‐ray detectors achieves enhanced energy resolution from 7% to 1.9% by reshaping bias electric fields and reducing noise. A novel spectral‐enhanced imaging strategy is developed, utilizing spectral dimensions to improve image contrast and quality.

Measurement of the 3He mass diffusion coefficient in superfluid 4He over the 0.45-0.95 K temperature range

, 2001
We have measured the mass diffusion coefficient D of 3He in superfluid 4He at temperatures lower than were previously possible. The experimental technique utilizes scintillation light produced when neutron react with 3He nuclei, and allows measurement of

Acidosis Forces Fatty Acid Uptake and Metabolism in Cancer Cells Regardless of Genotype

Advanced Science, EarlyView.
This study demonstrates that biological acidosis, commonly observed in tumors and ischemic conditions, actively promotes the protonation of fatty acids, thereby facilitating the uptake of their neutral forms. Consequently, the preference for lipid metabolism in acid‐exposed cells does not arise from genetic reprogramming that prioritizes lipids as the ...

Visualizing the Dynamic Wetting and Redistribution of Electrolyte in Lean‐Electrolyte Lithium‐Sulfur Pouch Cells via Operando Neutron Imaging

Advanced Energy Materials, EarlyView.
The inhomogeneous electrolyte wetting in lean‐electrolyte lithium–sulfur pouch cells is visualized by operando neutron tomography non‐destructively. Real‐time observation of electrolyte in different layers of pouch cells reveals different electrolyte wetting behaviors under various cell status, including cell rest, states of discharge, and charge at ...

Twinkle Light‐Inspired Aggregation‐Induced Emission “Lighting‐Up” Bacteriophages to Enhance Immunoassays via Spontaneous Amino‐Yne Click Reaction

Aggregate, EarlyView.
Herein, we present a twinkle‐light‐inspired “lighting‐up” bifunctional bacteriophage for fluorescence immunoassays via a spontaneous amino‐yne click reaction, and demonstrate its versatile potential for the highly sensitive detection of various targets, ranging from small molecules to pathogenic microorganisms, in complex samples.

Robotic‐Assisted Capture‐Systematic Evolution of Ligands by Exponential Enrichment of RNA Aptamers Binding to Small Molecules

ChemBioChem, EarlyView.
This study demonstrates the rapid selection of RNA aptamers that can target various small molecules through a newly established automated capture‐systematic evolution of ligands by exponential enrichment technique. Throughout the study, this method is applied to aptamer selection for several small molecules, resulting in aptamers that bind with high ...

The Impact of X‐ray Damage in Chemical Crystalline Materials and New Opportunities for Small Molecule Serial Crystallography

Chemistry – A European Journal, EarlyView.
The impact of X‐ray damage in chemical crystals was minimised by the introduction of area detectors in the late 20th‐century. Now, ever‐brighter X‐ray sources are re‐establishing X‐ray damage as a key challenge. This article reviews recent observations of X‐ray‐induced processes in chemical samples and discusses state‐of‐the‐art methodologies for their
