Graphene
New framework for nanoantenna light absorption
Harnessing light's energy into nanoscale volumes requires novel engineering approaches to overcome a fundamental barrier known as the 'diffraction limit.' However, researchers have breached this barrier by developing nanoantennas that pack the energy captured from light sources.

Engineers have created what may be viewed as the world's smallest incandescent lightbulbs, collections of near-nanoscale materials called 'selective thermal emitters' that absorb heat and emit light. Their research could have applications in sensing, photonics and perhaps in computing platforms beyond the limitations of silicon.

Scientists have designed a new method for post-operative wound closing and healing that is both fast and effective. This strategy revolves around engineered 'cell sheets' — or layers of skin-based cells. The procedure culminates in a wound dressing that is custom made for a specific cut or lesion that can be used to effectively treat open skin areas after surgeries. The findings were published in Scientific Reports on July 18th.

Physicists have constructed a two-dimensional spin transistor, in which spin currents were generated by an electric current through graphene. A monolayer of a transition metal dichalcogenide (TMD) was placed on top of graphene to induce charge-to-spin conversion in the graphene.

A research team has developed a novel data analysis method for prior evaluation of single crystal structure analysis. Their proposed method is based on precise estimation of a parameter inherent in preliminary-collected small data set. They demonstrated application of it to guest distinction in host-guest crystals before single crystal structure analysis and measurement design for precise crystallographic observation.
