Mesoionic N‐Heterocyclic Olefins, Imines, Thiones, Phosphinidenes and Their Application in Catalysis

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 3, 16 January 2026.
This minireview covers recent advances in the synthesis, reactivity, and metal‐free catalytic uses of mesoionic N‐heterocyclic olefins (mNHOs), imines (mNHIs), thiones (mNHTs), and phosphinidenes (mNHPs). Abstract Transition metal compounds are widely known for their ability to activate small molecules and are excellent catalysts for a wide range of ...

Stochastic Resonance Elucidates the Emergence and Periodicity Transition of Glacial Cycles

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Glacial cycles emerged with a 41‐kyr period after the Pliocene and later intensified with a 100‐kyr period in the mid‐Pleistocene, which were attributed to Earth's orbital variations. However, no significant changes in the orbital forcing were found at the two transitions, and the forcing was too small to drive these cycles. Here, a stochastic

Moisture sorption isotherms and thermodynamic properties of isomaltulose‐enriched mango

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 1, Page 260-271, 15 January 2026.
Abstract Background Moisture sorption isotherms and thermodynamic parameters are essential for designing and optimizing food processing and storage systems. This study aimed to evaluate these characteristics in untreated and osmotically treated mango slices, using isomaltulose and sucrose as osmotic agents.
