Dynamic Mechanical Analysis of Borassus Husk Fiber Reinforced Epoxy: Evaluating Suitability for Advanced Aerospace and Automotive Applications

Engineering Reports, Volume 7, Issue 4, April 2025.
Composite (DMA): This study examines the alkali treatment effect on Borassus husk fiber‐reinforced epoxy composites. Alkali treatment improves mechanical properties, including increased storage modulus, glass transition temperature, and damping factor, especially for 0.75‐h treated fiber/epoxy composite.

Enhanced Gamma Ray Radiation Resistance of Silicone Elastomers via Trace Addition of Perovskite Nanocrystals for Free Radicals Scavenging

Small Science, Volume 5, Issue 4, April 2025.
The addition of perovskite nanocrystals (PNCs) significantly mitigated free radical damage during γ‐ray irradiation, enhancing the irradiation resistance of silicone elastomers. After 300 kGy γ‐ray exposure, PNC‐silicone elastomers retained 89% mechanical strength, twice that of counterparts without PNCs (43%).

Next‐Generation Solar‐Powering: Photonic Strategies for Earth and Space Systems

Solar RRL, Volume 9, Issue 7, April 2025.
Key performance indicators (KPIs) for space or Earth photovoltaic systems and photonic strategies to enhance them are studied. The figure illustrates critical KPIs—efficiency, stability, cost, adaptability, and scalability—for space (top) and terrestrial (bottom) systems, showcasing how photonic strategies address unique challenges and improve ...
