Researchers have achieved a monumental leap in the efficiency and stability of inkjet-printed quantum-dot light-emitting diodes (QLEDs) by employing a pressure-assisted thermal annealing (PTA) technique, which enables the acquisition of highly ordered quantum-dot (QD) thin films via inkjet printing. This innovative approach has propelled QLEDs to unprecedented external quantum efficiency (EQE) over 23%, signaling a significant step toward the mainstream adoption of this display technology.

The recent LA fires drove home how dangerous wildfires can be when they encroach on urban areas. So-called 'wildland-urban interface' fires are on the rise. However, building codes and standards have long been based on fires that spread from building to building. To address this, a Tohoku University professor has updated international standards for large outdoor fires.

Research team led by Minyi Guo develops a novel fault tolerance framework for deep learning that optimizes checkpointing by leveraging idle system resources, reducing overhead to just 1% and outperforming existing methods in distributed training efficiency.

Researchers from the School of Metallurgy and Environment at Central South University, together with their collaborators, have proposed a novel buried interface strategy for stabilizing zinc anodes. The zincophilic Sn layer is buried under the corrosion-resistant ZnS layer (SZS), which effectively solves the dendrite formation and corrosion problems. The zinc anodes coated with SZS exhibit significantly enhanced cycling stability and long-term performance. This buried interface engineering strategy offers a promising avenue for the rational design of zinc anodes in rechargeable batteries, potentially advancing energy storage technology.

Tokyo, Japan – Researchers from Tokyo Metropolitan University have elucidated how hydrogen and carbon monoxide is adsorbed into solids containing a crown-motif structure of platinum and gold. Using quick-scan X-ray absorption measurements and theoretical calculations, they studied a solid of [PtAu₈(PPh₃)₈]-H[PMo₁₂O₄₀] called PtAu8-PMo12 and found that gas adsorption is affected strongly by the dimension of nanoscale voids in the structure. This highlights the importance of engineering voids in materials for next generation sensors and gas separation.
