Researchers from the Chinese University of Hong Kong discovered a topology-correlated affinity transition in both 2D and 3D packing-derived networks. Based on this transition, they reveal the strategies to build multifunctional systems with adjustable elasticity.
Researchers from the University of Tokyo have developed two-dimensional hole gas in solution-processed organic semiconductors, where an apparent insulator-metal transition has been experimentally observed for the first time. These results have just been published in Nature Materials.
Graded BHJ organic solar cell with well-defined vertical phase separation has the potential to surpass the classical counterpart. Here, the authors reveal solvent selection strategies for optimising morphology of the structure, enabling efficient, eco-friendly, and scalable solar cells.
In the past three decades, various optical spectroscopic techniques have been demonstrated to identify the chiral indices (n, m) of carbon nanotubes unequivocally even at the single-tube level. However, the accurate characterization of the handedness via optical spectroscopy has been unrealizable for single nanotubes. Here, we developed the Rayleigh scattering circular dichroism to fulfil the dream of complete structure identification of both chiral indices and handedness for single nanotubes.
Here we report a new polyacrylate dielectric elastomer with optimized crosslinking network by rationally employing the difunctional macromolecular crosslinking agent, which possesses desirable modulus (~0.073 MPa), high toughness (elongation ~2400%), and rapid response (bandwidth above 100 Hz).
