Journal of Food Quality, Volume 2017, Issue 1, 2017., 2017 Extraction of squalene, a potent natural antioxidant, from puffed A. hypochondriacus seeds was performed by supercritical fluid extraction (SCFE); besides, to have a blank for comparison, extraction was performed also by Soxhlet method using organic solvents (hexane). Chemical proximal composition and seed morphology were determined in raw, puffed, and

Catalase‐Based Air‐Cathode for Biocompatible Zinc–Air Battery
ChemCatChem, Volume 17, Issue 3, February 6, 2025.This article highlights the use of catalase (CAT) as electrocatalyst for the oxygen reduction reaction (ORR) in the air electrode of zinc–air batteries (ZABs). CAT immobilized with Nafion on electrode surfaces demonstrates great long‐term stability, exhibiting direct electrochemical response and retaining its bioactivity. CAT‐Nafion ZAB provides better

A simple synthetic approach to BaZrS3, BaHfS3, and their solid solutions
Journal of the American Ceramic Society, Volume 107, Issue 2, Page 698-703, February 2024.Abstract A simple synthetic approach to BaZrS3, BaHfS3, and their solid solutions is presented and discussed here. The synthesis is performed under relatively mild conditions (T = 500°C) and is complete in a few hours. The reactants are powdered BaS, Me (Me: Zr, Hf) and S in a ratio 1:1:3, mixed and sealed under vacuum in borosilicate glass ampoules ...
