An international team of researchers, affiliated with UNIST has presented an innovative wearable technology that will turn your skin into a loudspeaker.

The University of Tokyo Institute of Industrial Science researchers have created a model to explore the transition behavior of crystal lattices. Their system, based on spheroid particles with a permanent dipole, showed that the combination of anisotropic steric and dipole effects causes frustration that induces the coupling between polarization and strain, resulting in the self-organization. These findings are expected to contribute to the rational design of materials for applications including electro-mechanical actuators and electro-caloric refrigerators.

Sandwiching two-dimensional materials used in nanoelectronic devices between their three-dimensional silicon bases and an ultrathin layer of aluminum oxide can significantly reduce the risk of component failure due to overheating, according to a new study published in the journal of Advanced Materials led by researchers at the University of Illinois at Chicago College of Engineering.

SUTD researchers have discovered a one-size-fits-all master equation that shall pave the way towards better design of 2D material electronics.

Scientists have developed a photoelectrode that can harvest 85 percent of visible light in a 30 nanometers-thin semiconductor layer between gold layers, converting light energy 11 times more efficiently than previous methods.

An international research group improved perovskite solar cells efficiency by using materials with better light absorption properties. For the first time, researchers used silicon nanoparticles. Such nanoparticles can trap light of a broad range of wavelengths near the cell active layer. The particles themselves don't absorb light and don't interact with other elements of the battery, thus maintaining its stability. The research was published in Advanced Optical Materials.

Yale University researchers have demonstrated one of the key steps in building the architecture for modular quantum computers: the 'teleportation' of a quantum gate between two qubits, on demand.

Scientists at the Department of Energy's Oak Ridge National Laboratory induced a two-dimensional material to cannibalize itself for atomic 'building blocks' from which stable structures formed. The findings, reported in Nature Communications, provide insights that may improve design of 2-D materials for fast-charging energy-storage and electronic devices.

A Japan-based research team led by Osaka University synthesized non-toxic, cadmium-free light-emitting nanoparticles. The nanoparticles emit clean colors, which had not been possible previously with nanoparticles using the same non-toxic materials. This was achieved by modifying and optimizing the synthesis and treating the fabricated nanoparticles -- they were encased in semiconductor shells with an amorphous structure.
