Electrolytic hydrogen production powered by renewable energy is seen as an environmentally friendly means to ameliorate global climate and energy problems. A research team has now introduced a novel and inexpensive material for electrodes that may provide for highly efficient, energy-saving hydrogen production: porous, phosphorized CoNi2S4 yolk-shell nanospheres.

Roadside construction -- be it a detour, a closed lane, or a slow weave past workers and equipment -- work zones impact traffic flow and travel times on a system-wide level. The ability to predict exactly what those impacts will be, and plan for them, would be a major help to both transportation agencies and road users.

Demonstrating next-generation energy technology, researchers are using topology optimization and metal 3D printing to design ultra-compact, high-power heat exchangers.

Researchers are developing a smart dental implant that resists bacterial growth and generates its own electricity through chewing and brushing to power a tissue-rejuvenating light. The innovation could extend the usable life of an implant.
