Systematic Map of Chemical and Biological Surfactant Effects on Oxygen Mass Transfer at the Air–Water Interface

open access: yesWater Environment Research, Volume 98, Issue 1, January 2026.
This systematic review confirms that surfactants reduce oxygen transfer (kL/kLa), with concentration and hydrodynamics being critical factors. There was little diversity in the surfactants tested, and aquatic conditions were simplified, and variables (pH, viscosity) were neglected.

The physiological and pathological effects of sphingolipid metabolism and signaling in the central nervous system

open access: yesBrain Pathology, Volume 36, Issue 1, January 2026.
Sphingolipids are vital components of cell membranes. Metabolic disruptions of sphingolipids, including ceramide and sphingosine‐1‐phosphate, are linked to neurological disorders. This article summarizes the classification, structure, and metabolic processes of sphingolipids, and the physiological and pathological effects of sphingolipid metabolism and

Using boron as a tracer reveals how surface precipitates inhibit silicate dissolution in hyperalkaline solutions during alkali–silica reaction

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract Silicate dissolution under hyperalkaline conditions is a key process that affects the evolution of alkali–silica reaction (ASR) in concrete. In these environments, dissolution may involve multiple overlapping processes—including ion adsorption on reactive sites, transport of dissolved species, and the formation of alteration layers.
