Self‐Hollowing Synthesis of Hollow Nanosphere‐Stacked CuO Electrodes for Enhanced Photoelectrochemical and Electrochemical Applications

EcoMat, Volume 8, Issue 5, May 2026.
A template‐free, sol–gel self‐hollowing strategy enables one‐step fabrication of hollow nanosphere‐stacked metal oxide films directly on substrates. The resulting architecture enhances light scattering, charge transport, and surface reactivity, thereby improving performance in photoelectrochemical water reduction and electrochemical nitrate reduction ...

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, Volume 45, Issue 3, Page 548-582, May/June 2026.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Effective Removal of Fe and Ca From Coal Fly Ash for High‐Purity and High‐Surface‐Area Zeolite X Synthesis: A Comparative Study of Acid Refluxing and Acid Roasting Methods

ChemistryOpen, Volume 15, Issue 5, May 2026.
Coal fly ash (CFA) is an abundant industrial waste rich in silica and alumina and represents a viable feedstock for zeolite synthesis; however, high levels of calcium and iron limit zeolite purity and crystallisation. This study evaluates acid refluxing and acid roasting as pre‐treatment strategies for the simultaneous removal of Ca and Fe from high ...
