Bioactivity‐Guided Isolation of β‐Sitosterol From Terminalia glabrescens as a Potent Anti‐Zika Virus Agent

Chemistry &Biodiversity, Volume 23, Issue 1, January 2026.
ABSTRACT Zika virus (ZIKV) infection remains a global health concern due to its neurological complications and the lack of specific drugs or vaccines. This study investigated the anti‐ZIKV potential of an ethanolic extract from Terminalia glabrescens leaves.

Low‐Content Ru Catalysts for Efficient CO2 Methanation

ChemCatChem, Volume 18, Issue 2, 28 January 2026.
Five Ru‐based catalysts were synthesized and tested for CO2 methanation. Ru/TiO2 showed the highest performance and was further investigated using operando FT‐IR and DRIFTS. A mechanistic interpretation was proposed, and a kinetic model was developed and validated.

Physical simulation experiments on competitive dissolution of helium in helium-containing to helium-rich gas reservoirs

Meitian dizhi yu kantan
Background and Purpose Helium is widely applied in high-tech and scientific research fields due to its unique physicochemical properties. Formation water plays a key role in helium migration and enrichment. Typically, in the form of dissolved gas, helium is transported in pores or fractures by formation water. When helium-rich fluids migrate to shallow
