Blue emission at atomically sharp 1D heterojunctions between graphene and h-BN

Here, the authors explore the blue photoluminescence signal arising from the interface between graphene and h-BN arranged in in-plane heterostructures, and fabricate a blue light emitting device utilizing the heterojunction as the emitting layer.

Battery-free, wireless soft sensors for continuous multi-site measurements of pressure and temperature from patients at risk for pressure injuries

Uninterrupted monitoring of pressure and temperature at skin interfaces can help to minimize the potential for pressure injuries in hospitalized or bedridden patients. Here, the authors introduce a soft, skin-mountable sensor that can continuously provide readings via antennas mounted under bedding, and demonstrate the functionality and robustness of the devices on patients.

High figure-of-merit for ZnO nanostructures by interfacing lowly-oxidized graphene quantum dots

It is crucial to design ZnO with uniform nanoscale features to reduce thermal conductivity while maintaining electrical conduction pathways. Authors realize a high figure-of-merit value of 0.486 at 580 K by interfacing graphene quantum dots with three-dimensional nanostructured ZnO.

Metallic phase transition metal dichalcogenide quantum dots showing different optical charge excitation and decay pathways

Metallic phase transition metal dichalcogenides quantum dots show different pathways of optical charge excitation and decay according to the size and sort of defects, resulting into the large Stoke shift, two bands for charge excitation, and TRPL peak shift. This result is mainly ascribed to the valance band splitting and the emerging defect states originated from atomic vacancy of basal plane and edge oxidation.

Strengthening effect of single-atomic-layer graphene in metal–graphene nanolayered composites

Suppressing the movement of dislocations is critical in enhancing the strength of crystalline metals. Kim et al. demonstrate in Cu– and Ni–graphene nanolayered systems that single-layer graphene is effective in suppressing dislocation movement, resulting in a maximum strength of 4.0 GPa.
