A comprehensive review examined how nanomaterials could protect healthy tissues from radiation damage through targeted drug delivery, reactive oxygen species scavenging, anti-inflammatory activity, and physical radiation shielding. Although experimental studies show promising protection across several tissues and organ systems, most approaches remain preclinical, with long-term safety, biodistribution, scalability, and selective protection of healthy tissue still requiring investigation. 09/08/2026

Researchers first screened steel-fiber geometry and length for concrete impermeability, identifying 50-mm hooked-end and 40-mm crimped fibers as the best performers among those tested, before combining them with nano-silica to assess 28-day mechanical properties and microstructure. The hybrid mixtures performed best at 2% steel fiber and 1% nano-silica among the tested levels, with hooked-end fibers providing the strongest overall tensile and bending performance and microstructural analyses supporting a denser cementitious matrix. 09/07/2026

Researchers showed that an ultrathin, nanolayered boron nitride interlayer can improve the stability of perovskite quantum dot LEDs by passivating defects, suppressing ion migration, and enhancing heat dissipation. BN-optimized devices achieved an average peak EQE of 30.05% and a measured T50 lifetime of 102 hours at 2,000 cd m-2, with accelerated testing projecting a T50 of 25,263 hours at 100 cd m-2. 09/04/2026
