Structural and Electrochemical Evolution of Nickel Sulfides During Alkaline Hydrogen Evolution Reaction

open access: yesChemSusChem, Volume 19, Issue 7, 14 April 2026.
Post‐HER surface restructuring of nickel Sulfides (NixSy) through Sulfur leaching results in the formation of catalytically active Ni3S2, the most HER‐active nickel sulphide phase. The electrochemical activation process enhances hydrogen evolution performance while exhibiting self‐limiting behavior, ensuring long‐term catalyst stability in alkaline ...

White Light, Magnifying Endoscopy, Endocytoscopy, and Artificial Intelligence in Diagnosis of Early Colorectal Cancer: A Comparative Study

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Early detection of colorectal cancer is critical for improving prognosis. However, assessing invasion depth—distinguishing between superficial cancer (T1a) and deep submucosal invasive cancer (T1b)—remains challenging. Recently, artificial intelligence (AI)‐assisted computer‐aided diagnosis (CADx) systems have been introduced to ...
