Numerical Simulation of Vertical Profiles of Meteorological Variables in Urban Neighborhoods: Coupling an Urban Vertical Diffusion Model With a Single‐Layer Urban Canopy Model (UVDM‐SLUCM)

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Heterogeneous landscape leads to large variations of urban microclimate in all dimensions, yet the vertical variability of meteorological elements within the urban canopy layer (UCL) has been rarely examined. In the present study, we developed an urban vertical diffusion model coupled with a single‐layer urban canopy model.

Acceleration of Atmospheric Freeze‐Drying of Food: Methods, Implications, Commercialization, and Future Directions

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 2, March 2026.
ABSTRACT Atmospheric freeze‐drying (AFD) is an emerging and cost‐effective alternative for drying food and pharmaceutical ingredients, offering lower investment and operational costs compared with vacuum freeze‐drying (VFD). However, industrial adoption is limited due to the significantly longer time required, resulting from consistently lower drying ...

Covalent Organic Frameworks for Water Sorption: The Importance of Framework Physical Stability

Advanced Functional Materials, Volume 36, Issue 13, 12 February 2026.
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

A Guideline to Evaluate Sorbent Performance for Atmospheric Water Harvesting

Advanced Energy and Sustainability Research, Volume 7, Issue 2, February 2026.
Reporting guidelines for atmospheric water harvesting sorbents allow benchmarking between research groups across seven key performance indicators (KPIs). Beyond simple equilibrium values (such as capacity or maximum water uptake), these KPIs validate sensitivity, reversibility, regeneration conditions, chemical stability, kinetics, and water quality ...
