Liquid‐Catalyst‐Activated Sparingly Solvating Electrolytes for Low‐Temperature Potassium‐Sulfur Batteries

Advanced Energy Materials, Volume 16, Issue 23, 17 June 2026.
This study develops a novel sparingly solvating electrolyte for potassium–sulfur batteries, utilizing tetrahydrofuran (THF) to induce an anion‐dominated solvation structure that eases polysulfide shuttling and forms an inorganic‐rich solid–electrolyte interphases (SEI). Dimethyl diselenide (DMDSe) accelerates quasi‐solid‐state transformations, reducing

Aggregation of Ag6‐Derived Clusters in Dialdehyde Hydroxypropyl Methylcellulose for Fluorescent Security Ink

Aggregate, Volume 7, Issue 6, June 2026.
Dialdehyde hydroxypropyl methylcellulose acts as a solvent‐responsive polymer microenvironment, promoting Ag6‐derived cluster aggregation after ethanol addition and enabling bright yellow emission under UV excitation. After being formulated into an ink, the aggregation‐regulated system supports screen printing of fluorescent security patterns, latent ...

The Discrete Fourier Transform and Signal Processing

The Discrete Fourier Transform (DFT) is a mathematical function that is foundational to our digital world. It converts a sampled signal from the time domain to the frequency domain, allowing us to observe what frequencies are present in the signal.

A Spectral Matching Algorithm Based on the Wasserstein Metric

Journal of Chemometrics, Volume 40, Issue 6, June 2026.
ABSTRACT Through visual inspection, scientists can easily judge the similarity of pairs of spectra from different sources, whether they are experimental measurements, spectra libraries, or spectra calculations. Spectral similarity is recognized when the peak patterns appear similar, even if the peak positions are shifted or the peak amplitudes are ...
