Electrical engineers have reported solving a lingering question about how a two-dimensional crystal composed of cesium, lead, and bromine emitted a strong green light, opening the door to designing better light-emitting and diagnostic devices.
Chemical engineers have devised a new way to create very tiny droplets of one liquid suspended within another liquid, known as nanoemulsions. The researchers also found a way to easily convert the liquid nanoemulsions to a gel when they reach body temperature, which could be useful for developing materials that can deliver medication when rubbed on the skin or injected into the body.

Researchers have discovered a way to apply nanoparticles to plant leaves so that they travel through the plant all the way to the root. This is the first time that anyone has systematically studied how nanoparticles move through the leaf, into the plant, to the root, and exude into the soil.

Scientists have created new inorganic crystals made of stacks of atomically thin sheets that unexpectedly spiral like a nanoscale card deck. The surprising structures may yield unique optical, electronic and thermal properties, including superconductivity, the researchers say.

Researchers have made a strange and startling discovery: Nanoparticles that are engineered with DNA in colloidal crystals behave just like electrons. Not only has this finding upended the current, accepted notion of matter, it also opens the door for new possibilities in materials design.

Physicists shed light on a novel Mott state observed in twisted graphene bilayers at the “magic angle.” The novel Mott state favors ferromagnetic alignment of the electron spins, meaning that the spins of pairs of electrons are aligned parallel to each other, even though these electrons strongly repel each other – a phenomenon unheard of in conventional Mott insulators, in which the spins of two electrons sitting next to each other are anti-parallel.
