Separator Engineering for Stable Zinc Anodes in Aqueous Zinc‐Ion Batteries

open access: yesBatteries &Supercaps, Volume 9, Issue 4, April 2026.
Aqueous Zinc‐ion batteries boast high energy density, low cost, and safety but face challenges like zinc dendrites, hydrogen evolution reaction, and anode corrosion. Separator engineering—modifying glass fiber separators and developing novel ones—addresses these issues, boosting their electrochemical performance and long‐cycle stability.

3D MR Thermometry Using Bi‐Directional Segmented EPI for Transcranial‐Focused Ultrasound

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 4, Page 2106-2116, April 2026.
ABSTRACT Purpose To evaluate the feasibility of replacing clinically utilized 2D thermometry with 3D segmented EPI‐based thermometry with equivalent accuracy, precision, and scan time. Methods A 3D segmented EPI (segEPI) trajectory was modified to allow readouts along both the forward and reverse direction for each phase encoding line, and the sequence

Beeswax: Food and beyond

open access: yesFood Biomacromolecules, Volume 3, Issue 1, Page 93-112, March 2026.
Abstract Honeybees (Apis mellifera L.) are an important class of insects that are the most beneficial in terms of economy. Beeswax is the second most important bee products after honey. Its commercial importance is due to its antimicrobial, antioxidant, anti‐inflammatory and antiseptic as well as regenerative properties.
