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.

New research from Monash University scientists has revealed that microscopic life is actively breaking down decades-old mining waste in South Australia, turning stable radioactive and toxic metals into mobile nanoparticles that can easily travel through the environment.

Researchers synchronized up to 105,000 spin Hall nano-oscillators, with phase ordering occurring in 10 to 45 ns across increasingly large two-dimensional lattices. The devices showed microwave power scaling with oscillator number and exceptionally narrow linewidths, supporting their potential use in future unconventional computing hardware.

Catalyst performance is central to efficiency, selectivity, and process reliability in the chemical and catalyst industries.

Researchers compared additive-free nanocellulose and nanochitin films, gels, and laboratory coatings for paper packaging. Nanochitin provided better barrier performance, while nanocellulose produced stronger films and better preserved paper brightness.
