Measuring Dry Deposition of Sea Spray Aerosol and Height of Aerosol Plume Using a Controlled Wave Pool

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Deposition of sea spray aerosols facilitates atmospheric corrosion of materials, requiring maintenance and replacement over time. However, the dimensions of sea spray aerosol plumes produced from breaking waves have not been well‐characterized, limiting useful prediction of particle transport downwind and atmospheric corrosion. Therefore, this

Enhanced Roofs for Passive Building Design: A Systematic Review of Thermal and Energy Performance

open access: yesApplied Research, Volume 5, Issue 5, October 2026.
This systematic review evaluates PCM‐ and NePCM‐integrated roofing systems for passive cooling. PCM roofs reduce heat flux and indoor temperature fluctuations, while NePCMs improve thermal conductivity with latent heat trade‐offs. Hybrid cooling strategies enhance performance, and future challenges in scalability, durability, and practical ...

Revisiting the Carbon Footprint of Single‐Use Technologies in Biomanufacturing: A Bottom‐Up Analysis Reveals a Paradigm Shift

open access: yesBiotechnology and Bioengineering, Volume 123, Issue 10, Page 2802-2814, October 2026.
ABSTRACT The biopharmaceutical industry increasingly relies on single‐use technologies (SUT) for operational flexibility. For a long time, SUT was considered more sustainable than stainless‐steel (SST) systems due to water and energy savings. This study re‐evaluates this paradigm via a detailed bottom‐up analysis of the SUT carbon footprint at the 2000
