Achieving high specific detectivity at room-temperature, comparable to background-limited mid-infrared (MIR) performance, has been a longstanding challenge in the MIR optoelectronics. Towards this goal, scientist in Singapore designed a bipolar-barrier tunnel heterostructure, which effectively suppresses dark current while facilitating the tunneling of photogenerated carriers, enabling high-sensitivity mid-infrared photodetection. The design will open new avenues for advancement of next-generation infrared optoelectronic devices.

In this review, we first introduce the fundamentals of OLEDs, including their working mechanisms, materials and device structures. We then summarise the applications of fibre-shaped and planar OLEDs in applications of wearable displays, photo-sensing and photomedicine. Finally, we discuss the challenges and future opportunities for developing high-performance wearable electronic devices based on OLEDs.

Controlling light at the nanoscale unlocks opportunities for future technologies. Scientists from Australia and the United States have discovered that micron-scale gold antennas, fabricated on the surface of calcite, can act as miniature mirrors to launch “ghost” light waves over unprecedented distances. This breakthrough, which increases propagation length by four-fold, offers potential applications in improved heat management in high-performance computers. This strategy paves the way for next-generation nanophotonic technologies.

This study extends Thouless pumping from periodic to quasi-periodic driving, uncovering the intrinsic link between topological transport and the irrational frequency ratio of the lattice modulation. The findings broaden the applicability of Thouless pumping in topological transport.

A perspective published by researchers at the University of Science and Technology Beijing discusses research by Stoddart et al. in Nature Chemistry that demonstrates that engineered supramolecular crystals can optimize hydrogen storage performance.

New computer simulations that model every atom of a protein as it folds into its final three-dimensional form support the existence of a recently identified type of protein misfolding.
