Crystal Facets Reactivity in Metal–Organic Frameworks

Israel Journal of Chemistry, Volume 66, Issue 3, May 2026.
In this mini review, it is highlighted how the crystal facets reactivity of metal–organic frameworks can be dictated by bond strength, surface functionality, particle size, defect density, or crystal morphology. Precise control of these parameters enables deliberate exposure of crystal facets, leading to enhanced crystal surface accessibility and ...

Interference of TiO2 in Fricke Dosimetry: Adsorption Mechanisms and Dose Measurement Challenges under Gamma Irradiation

ChemistryOpen, Volume 15, Issue 4, April 2026.
The presence of TiO2 in Fricke dosimetric systems introduces complex interferences under gamma irradiation. Adsorption of Fe2+/Fe3+ ions, coupled with radiolytic and surface‐mediated processes, alters redox equilibria and apparent absorbed dose values, highlighting critical challenges in chemical dosimetry applied to heterogeneous radiolytic ...

Los nuevos conceptos en oxido-reducción y la respiración animal

Revista de la Facultad de Medicina, 1942
En Química General, una oxidación consiste en la pérdida de uno o más electrones, o sea en la pérdida de un quantum o varios quanta de electricidad negativa. Y una reducción es lo contrario: la adquisición de uno o más electrones. La anterior explicación
