Si−H Activation via Dynamic Permutational Isomerism: A Ligand‐Directed Route to Dehydrogenative Coupling

open access: yesAngewandte Chemie International Edition, EarlyView.
Ligand‐controlled dynamic permutational isomerism in pentacoordinate silicon intermediates enables metal‐free dehydrogenative Si─O coupling. The accessibility of axial hydride positions dictates whether Si─H bond activation or Si─N bond cleavage occurs, providing a mechanistic framework for understanding hydrogen release and coupling processes in ...

Preparation of MOEAMCl and MAAm Based Hydrogels and Effective Use in Anionic Dye Adsorption

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 16, April 20, 2025.
ABSTRACT In this study, hydrogels based on [2‐(Methacryloyloxy)ethyl]trimethylammonium chloride (MOEAMCl) and methacrylamide (MAAm) were synthesized for the removal of anionic dyes from aqueous solutions. Following detailed characterization, the use of hydrogels for methyl orange (MO) adsorption was investigated.

Anatolian ground squirrel (Spermophilus xanthoprymnus) retina: Comparative expression of synaptophysin, NeuN, calbindin‐D28k, parvalbumin, glial fibrillary acidic protein, and Iba‐1 during pre‐hibernation and hibernation

open access: yesThe Anatomical Record, EarlyView.
Abstract Hibernation induces significant molecular and cellular adaptations in the retina to maintain function under reduced metabolic conditions. This study aimed to investigate the expression of neuronal, synaptic, and glial markers in the retina of Spermophilus xanthoprymnus during pre‐hibernation and hibernation periods using immunohistochemical ...
