Overcoming Thickness–Durability Trade‐Off in PEM Fuel Cells via Stretched PTFE Nanofiber‐Reinforced Composite Membranes

Advanced Energy Materials, Volume 16, Issue 4, 28 January 2026.
By combining emulsification electrospinning with a precision thermomechanical biaxial stretching process, ultrathin 3‐fold stretched polytetrafluoroethylene nanofiber (3‐sPTFE NF) reinforcements are developed that enable the fabrication of highly durable and high‐performing reinforced composite membranes (RCMs).

Toward Reconciling Bottom‐Up and Top‐Down Estimates of N2O and CH4 Emissions in Rotterdam

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 21, 16 November 2025.
Abstract Cities are key areas for implementing measures to reduce greenhouse gas emissions; however, large uncertainties exist in both “bottom‐up” inventories and “top‐down” estimates of urban N2O and CH4 emissions. We combine top‐down and bottom‐up approaches to evaluate the N2O and CH4 emission inventory for Rotterdam based on high‐precision ...
