Researchers have demonstrate a simple platform to achieve architectural polymorphs of graphene quantum dots (GQDs) by maneuvering the intra/intermolecular interactions of the constituent GQDs in binary solution systems.
Inspired by the varying colors that gleam off of beetle shells, scientists have developed color-shifting nanoparticles that can change hue even after being embedded into a material. A report on the new, inexpensive technique, could lead to the production of easier-to-read sensors and anti-tampering tags.
Researchers incorporated a photocatalyst in a moisture-absorbing, semiconducting paint that can produce hydrogen from water in the air when exposed to sunlight. The development could enable hydrogen fuel production in almost any location.
As computers and cell phones become smarter and faster, they use more electricity. More electricity means more heat. Dispelling that heat uses more energy. New materials that couple electric and magnetic states of a material could break this cycle.
Scientists built a new design and chemistry for electrodes that involves advanced, nanostructured electrodes containing molybdenum disulfide and carbon nanofibers. These composite materials have internal atomic-scale pathways for both fast ion and electron transport, allowing for fast charging.
