  • 3D photonic nanostructures can manipulate the amplitude, phase, and polarization of light, but their bottom-up fabrication is hindered by limited structural control. Here, the authors present chiral 3D structures through multi-dimensional transfer printing of multilayer quantum dot patterns.

  • Thermoelectric materials enable us to convert heat into electricity, but their application has been limited to high-temperature heat sources. Here, the authors show the direct conversion of low-grade waste heat into chemical energy via combining thermoelectric materials with biocatalysts below 100 °C.

  • 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.

  • Charge replenishment from the supports to catalysts can play a key role in stabilizing active-Ir(III) to realize an efficient and durable oxygen evolution reaction. Here, the authors report an excess electron reservoir, greatly enhancing charge donation for improved water-splitting performance.

  • One pathway for improving the performance of optoelectronics is the tailoring energy bands of the charge transport layer. Here, Kim et al present a charge transfer complex composed out of nanodomains of MoO3 embedded within an NiO matrix, significantly improving green and blue OLED performance.
