A review of cellulose nanomaterial-based electrospun membranes finds that nanocellulose can increase mechanical strength, hydrophilicity, permeability, fouling resistance, and contaminant-removal capabilities across several water-treatment designs. The authors also examine solvent choice, hydraulic stability, manufacturing scale-up, life-cycle impacts, and the practical requirements for moving these membranes beyond laboratory studies.
Researchers engineered HZO-SiO2 nanomechanical resonators that use nanoscale oxide layering and phase-dependent elasticity to suppress temperature-driven frequency drift while retaining electrical tunability. The CMOS-compatible platform combined passive thermal compensation with voltage-controlled stiffness tuning, highlighting how ferroelectric oxide nanostructures could support more stable integrated resonators.
Researchers developed a sterically regulated electrolyte that uses a non-flammable cyclic fluorinated diluent to form isolated solvation nanoclusters, improving lithium-ion transport and stabilizing interfaces in lithium metal batteries. The system enabled NCM811 coin cells to retain 80% capacity after more than 800 cycles, while a separate 6 Ah pouch cell exceeded 500 Wh kg?¹ and showed favorable behavior in nail-penetration and severe overcharge tests.
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.
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.
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.
Alemnis AG has released the MLC-0.025, a new low-force load cell designed to extend high-precision mechanical testing into lower-force applications.
Oak Ridge National Laboratory researchers developed an artificial intelligence system that can manipulate individual molecules to build custom materials with atomic precision.
Researchers reviewed 88 studies to assess how nanotechnology could improve firefighters' thermal protective clothing by enhancing flame resistance, thermal management, breathability, and particle filtration, and by adding functions such as sensing. The review finds strong potential for multifunctional nano-engineered textiles but highlights major barriers including scalability, durability, cost, standardized testing, and nanomaterial safety.
A review published in Advanced Materials examines the emerging field of smelltronics, which combines advanced sensing materials, engineered interfaces, sensor arrays, and computational methods to detect and distinguish information-rich volatile organic compounds. The authors highlight how molecular recognition, device integration, machine learning, and improved sensor stability could help translate digital odor sensing into applications spanning healthcare, food monitoring, environmental sensing, and security.
