Low-cost and earth abundant, NiMoalloy nanocrystals, with sizes ranging from 18-43 nm and varying Mo composition (0.0-11.4%), were produced by a colloidal chemistry method for alkaline HER reactions. For a water splitting current density of ˜10 mA/cm, these alloys demonstrate over-potentials of −62 to −177 mV, which are comparable to commercial Pt-based electrocatalysts (−68 to −129 mV). The cubic NiMoalloy nanocrystals exhibit the highest activity as alkaline HER electrocatalysts, outperforming commercial Pt/C (20 wt %) catalyst.

Slug flow manufacturing systems and methods for production of battery microparticle materials such as nickel-cobalt-manganese oxide (NCM) are disclosed. The slug flow reactor system is capable of producing microparticles reproducibly and continuously in desired scales. The system may be run with fast kinetics (e.g., complete reaction from nucleation to particle recovery completes within a few minutes) and near-ambient reaction temperature (e.g., allowing to use inexpensive plastic tubing). The system allows control of composition (overall, and radial profile) and size of microparticles without changing chemistry nor increasing temperature. The platforms offers the ability to conveniently generate uniform microparticles, of controllable size with an ease of scale up.

A method for treating a fabric for ultraviolet radiation protection is disclosed which comprises the steps of adding zinc oxide nanoparticles to a solution of 3-glycidyloxypropyl-trimethoxysilane, adding silicon dioxide to the mixture of zinc oxide nanoparticles and 3-glycidyloxypropyl-trimethoxysilane, placing a fabric in the mixture of zinc oxide nanoparticles, 3-glycidyloxypropyl-trimethoxysilane, and silicon dioxide, curing the fabric, and washing the fabric.
