Sensitivity of freshwater periphytic diatoms to agricultural herbicides [PDF]
, 2009 The biomonitoring of pesticide pollution in streams and rivers using algae such as diatoms remains difficult. The responses of diatomcommunities to toxic stress in streamwater are disturbed by the variations of environmental parameters.

Covalent Organic Frameworks for Water Sorption: The Importance of Framework Physical Stability
Advanced Functional Materials, EarlyView.This study explores the water‐vapor stability of 2D covalent organic frameworks (COFs) with varying pore sizes. Results reveal microporous COFs demonstrate superior stability compared to mesoporous ones, despite lower water uptake. Mesoporous keto‐enamine‐linked COFs show enhanced stability due to intralayer hydrogen bonds, confirmed by simulations and
