Polypropylene Nanoplastic Exposure to Respiratory Epithelial Barrier‐On‐Chip and Interfacial Interactions With Human Serum Albumin

Allergy, EarlyView.
Exposure to 305 nm PP NPs significantly disrupts the airway barrier‐on‐chip, reducing TEER, suppressing ZO‐1/ACE2 expression, and triggering ROS‐mediated apoptosis. In biological media, PP NPs exhibit a biphasic adsorption pattern, leading to the formation of a protein corona that increases their size to 364 nm.

Catalytic Upcycling of Polyolefins

Chemical Reviews
The large production volumes of commodity polyolefins (specifically, polyethylene, polypropylene, polystyrene, and poly(vinyl chloride)), in conjunction with their low unit values and multitude of short-term uses, have resulted in a significant and pressing waste management challenge. Only a small fraction of these polyolefins is currently mechanically

CFD Analysis of Dual‐Layer PCM Roofs for Thermal Mitigation in Residential Buildings

Heat Transfer, Volume 55, Issue 4, Page 2290-2312, June 2026.
ABSTRACT This study presents a computational fluid dynamics analysis of dual‐layer phase change material (PCM) roofs for passive cooling in residential buildings under the hot and humid climate of Bangladesh. A three‐dimensional transient model was developed in ANSYS Fluent using the enthalpy–porosity approach to simulate coupled heat conduction ...

Mitigation of UV‐Induced Degradation in Lightweight SHJ Solar Modules via a UV‐Downshifting Encapsulation Strategy

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 6, Page 771-785, June 2026.
Lightweight SHJ solar modules with UV‐downshifting encapsulants effectively mitigated UV‐induced degradation (UVID). However, a reduction in the downshifting (DS) effect was observed, supposedly caused by photooxidation. A novel dual‐layer encapsulation was proposed to ensure the UV utilization and stability of lightweight SHJ solar modules, preserving
