Nanocoating technology reduces interfacial resistance between electrode and electrolyte, maximizing efficiency in both hydrogen production and power generation
Polymer solar cells (PSCs) promise lightweight, flexible, and scalable solar energy, yet their efficiency still lags behind inorganic counterparts due to high exciton binding energy, low ambipolar carrier mobility, and substantial non-radiative recombination losses.
Researchers developed an AI-assisted, ligand-triggered, room-temperature method to produce FAPbI3 perovskite nanocrystals, combining robotic experimentation, machine learning, and continuous-flow synthesis to improve control over particle size and uniformity. The process produced nearly 13 g of nanocrystals in 1 h, lowered estimated production costs, and yielded laboratory solar cells with power conversion efficiencies above 19% and improved operational and thermal stability.
Researchers built an InSb-lithium niobate acoustoelectric current source that converts RF-driven surface acoustic waves directly into DC, with a wired output tunable from 1.22 nA to 25.46 µA and stable operation over 12 hours. The same platform also operated under wireless RF excitation and was tested for low-current stimulation in a rat wound model, although its RF-to-DC efficiency remains far below that of conventional rectifiers.
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.
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.
Researchers developed a coaxial core-shell nanofiber separator that combines high thermal stability with substantial stretch tolerance for lithium-ion batteries. The membrane showed far less heat-induced shrinkage than commercial polyethylene and maintained stronger battery performance at elevated temperatures, although repeated stretching degraded its pore network.
Researchers developed an organelle-mimetic ZIF-67/CoS/CdS nanoreactor that directs photogenerated charges to co-produce hydrogen and selectively convert lactic acid into pyruvic acid. The catalyst maintained strong performance under natural sunlight and at a 1000 cm² reaction area, supporting further development of scalable solar-driven chemical production.
This review examines how controlled electrostatic discharge can increase current output in triboelectric nanogenerators via electron avalanches and enable DC output in specific device designs. It surveys nano-enabled energy-harvesting systems for chemical removal, nitrogen fixation, ammonia synthesis, and self-powered gas sensing, while identifying barriers to commercialization.
This review proposes eco-nanozymology as a framework for designing nanozymes that act as catalytic regulators in energy conversion, pollutant degradation, biomass valorization, and biogeochemical cycling. It highlights progress in nanozyme design while emphasizing that real-world safety, environmental fate, scalability, and regulatory oversight remain major challenges.
