Anti/De‐Icing and Broad‐Band IR Stealth: Ag2S‐Modified Wool

EcoMat, Volume 8, Issue 5, May 2026.
This study develops the multifunctional HMWF@Ag2S wool fabric via a simple two‐step strategy: fabricating hydrophobic HMWF through DA‐HDTMS reactions, then introducing Ag2S particles onto it via a green method to form a micro‐nano structure; the optimized fabric boasts 62.3% photothermal efficiency with power generation, anti/de‐icing performances and ...

Observed and Modeled Changes in Boundary‐Layer and Surface‐Level Actinic Flux Due To Wildfire Smoke Plumes in the California Central Valley in Summer 2018

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Wildfire smoke is increasingly degrading U.S. air quality via the emission and transport of pollutants. Smoke's direct role as a pollutant is well‐documented; however, smoke also affects pollutant concentration indirectly by changing the shortwave actinic flux necessary for photochemical reactions.

Aging Lifetime of Atmospheric Brown Carbon Determined From Measurements of Wildfire Carbonaceous Aerosol in Western Canada

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract The atmospheric abundance of black carbon (BC) and brown carbon (BrC) aerosol particles has been measured using aethalometry at four locations (Kamloops, BC; Prince George, BC; Joussard, AB; East Trout Lake, SK) in Western Canada through the 2023 and 2024 wildfire seasons (June to November).

A Compact Highly Sensitive Cone–Sphere Photoacoustic Spectroscopy Sensor for Real-Time Detection of Dissolved Acetylene in Transformer Oil

Photonics
In this work, we report a compact and highly sensitive photoacoustic spectroscopy (PAS) system based on a cone–sphere coupled photoacoustic cell (CSC-PAC) for real-time detection of trace acetylene (C2H2) dissolved in transformer oil.
