Temporal and Spatial Dynamics of Surface Water Temperature Changes in China's Major Lakes

open access: yesWater Resources Research, Volume 61, Issue 7, July 2025.
Abstract Globally the lake surface water temperature (LSWT) has shown an upward trend and exhibits significant spatial heterogeneity, but previous studies have indeed delved it under current period. Here, we investigated the characteristics of LSWT variation in major lakes of China over two centuries.

Recent Advances in Functionalized Isocyanide Synthesis and Natural Products Containing the Isocyano Functional Group and Their Biological Properties

open access: yesChemistrySelect, Volume 10, Issue 16, April 25, 2025.
One important strategy to increase the versatility of isocyanides is to employ functionalized isocyanides. It should be mentioned that after being functionalized, isocyanides can precisely regulate their reactivity during a chemical reaction. Natural occurring isocyanides exhibit distinct biosynthetic pathways, and understanding these pathways sheds ...
