Full‐pattern fitting of X‐ray powder diffraction data to determine allophane and organic matter contents in soils

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Full‐pattern fitting of X‐ray powder diffraction (XRPD) data using reference materials has attracted increasing attention as a high‐throughput method to determine the contents of long‐range‐ordered (i.e., crystalline) materials in soils. We hypothesized that this XRPD method can also be used to quantify short‐range‐ordered (SRO) materials with

Curated set of tool compounds to probe PYK2 and FAK signaling in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Proline‐rich tyrosine kinase 2 (PYK2) and focal adhesion kinase (FAK) are non‐receptor tyrosine kinases implicated in Alzheimer's disease (AD), but their functional role in microglia remains understudied. Selective pharmacological tools are required for preclinical studies leading to translational therapeutic development.

Nitroxide‐Mediated Fluorescence Quenching: Synthesis and Applications for the Detection of ROS in Biological Systems

Advanced Sensor Research, Volume 5, Issue 3, March 2026.
ABSTRACT Profluorescent nitroxides (PFNs) have established themselves as powerful tools for monitoring oxidative processes and subcellular redox dynamics by reactive oxygen species (ROS). Their characteristic “off–on” behavior arises from the efficient, proximity‐driven quenching of covalently bound fluorophores by paramagnetic nitroxide radicals ...
