TL;DR: The synthesis of unoxidized graphene/alumina composite materials having enhanced toughness, strength, and wear-resistance by a low-cost and environmentally benign pressure-less-sintering process is reported on.

TL;DR: In this article, a review of recent developments in structure designs for highly durable flexible OLEDs, ranging from alternative transparent electrodes to thin-film encapsulation layers, in which solution concepts for the existing critical issues of flexible OLED displays are addressed.

TL;DR: The surface plasmons (SPs) in optically thin metal fi lms contribute to extraordinary optical transmission (EOT) through subwavelength apertures as discussed by the authors.

TL;DR: Transfer printing is a materials assembly technique that uses elastomeric stamps for heterogeneous integration of various classes of micro-and nanostructured materials into two-and three-dimensionalally organized layouts on virtually any type of substrate as mentioned in this paper.

TL;DR: In this paper, the first organic light-emitting diodes (OLEDs) on actual soft fabrics that can be used for a wearable display were reported, which showed a high current efficiency of around 8cd/A, reliability during a 1000 cycle bending test with a bending radius of 5mm, and clear green emission up to an emission angle of 70°.
