Auxetic Behavior in JUC‐530: The Effect of Interstitial Molecules on Framework Deformation

physica status solidi (b), Volume 263, Issue 5, May 2026.
Auxetic behavior in the JUC‐530 covalent organic framework is predicted by molecular modeling to arise from a cooperative tetrahedral‐flattening mechanism within the framework topology. Guest molecule loading (N2, CH4, benzene) is shown to suppress the negative Poisson's ratio response.

Enhanced Gamma Radiation Shielding Using Epoxy Quartz Fabric Composites Reinforced With CoCl2 Microparticles

Advanced Engineering Materials, Volume 28, Issue 8, 22 April 2026.
The growing demand for lightweight, nontoxic, and multifunctional gamma shielding materials has intensified efforts to find alternatives to conventional lead and aluminum‐based protectants. In this work, we develop epoxy quartz fabric composites reinforced with cobalt chloride (CoCl2) microparticles, fabricated via hand lay‐up with varying filler ...

Modeling and Design Principles for Plasmonic Nanoparticle‐Enhanced Perovskite Solar Cells: A Comprehensive Review

Solar RRL, Volume 10, Issue 7, 15 April 2026.
Perovskite solar cells have reached high power‐conversion efficiencies, yet further gains require improved optical design, particularly in the near‐infrared. This review surveys analytical and numerical studies on plasmonic nanoparticle‐enhanced perovskite solar cells (PSCs), clarifying key enhancement mechanisms. The influence of nanoparticle material,
