Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and

Characterization of Goat Milk Fermented With Streptococcus thermophilus, Limosilactobacillus mucosae CNPC007 and Inulin With Addition of Cereus jamacaru

Applied Research, Volume 5, Issue 3, June 2026.
Limosilactobacillus mucosae maintained viability above 7 log CFU/g during storage of the fermented goat milk with inulin and Cereus jamacaru jam and survived over 4 log CFU/g during the in vitro gastrointestinal simulation. This jam enriched the total phenolic content of the fermented milk that achieved overall acceptability scores close to or above 7.
