Achromatic metasurface waveguide technology is revolutionizing augmented reality (AR) displays by addressing the longstanding issue of chromatic aberration. Developed by a research team from China, this innovative approach combines inverse-designed metasurface couplers with a high refractive index waveguide, achieving superior color accuracy and uniformity across a wide field of view. The technology promises to enhance the visual experience in compact AR systems, paving the way for advanced applications in various fields by overcoming the limitations of traditional diffractive waveguides.

Dimethoxymethane (DMM) carbonylation provides a mild, green and sustainable route for production of degradable plastic monomers, glycolic acid. ZEO-1 zeolite contains large cages comprised of 16×16 and 16×12 MRs intersection showing high DMM carbonylation activity and small cages comprised of 12×12 MRs intersection showing high DMM disproportionation activity. Zeolite ZEO-1 exhibits both high DMM carbonylation and disproportionation activity due to its unique structure and active sites distribution.

Deep-blue perovskite light-emitting diodes (PeLEDs) based on reduced-dimensional perovskites (RDPs) still face a few challenges including severe trap-assisted nonradiative recombination, sluggish exciton transfer, and undesirable bathochromic shift of the electroluminescence spectra. An in situ chlorination (isCl) post-treatment strategy was employed to regulate phase reconstruction and renovate multiple defects of RDPs including halide vacancies and lead-chloride antisite defects. Consequently, deep-blue PeLEDs with a maximum external quantum efficiency of 6.17% at 454 nm were demonstrated.

Researchers from Shihezi University synthesized Zn-MOF and bimetallic ZnCe-MOF using a microchannel reactor for enhanced CO₂ adsorption. ZnCe-MOF showed higher adsorption capacity due to Ce doping, which increased pore size and adsorption energy. This eco-friendly method enhances CO₂ capture efficiency.

Researchers from East China University of Science and Technology developed TEPA-functionalized SiO₂ adsorbents for CO₂ capture. Active amine sites enhanced adsorption capacity. The 40TEPA-10PEG/SiO₂ showed high stability and efficiency, ideal for direct air capture.

Researchers from Harwell Science and Innovation Campus explore methanol dynamics in copper-loaded zeolites using neutron scattering, revealing insights into diffusion behavior and its impact on catalytic processes.

The electromagnetic responses of metamaterial microstructural units are typically described using classical polarization theory models from dielectric physics, such as the Lorentz and Drude models. However, there has been a notable absence of the Debye model, which holds significant importance in dielectric physics. Chinese scientists have now successfully uncovered a novel broadband electromagnetic response mechanism in metamaterial microstructures based on polarization theory - Debye relaxation.
