Deciphering true active sites under identical mass transport conditions is crucial for understanding catalytic mechanisms. By establishing uniform mass transfer and implementing controlled experiments to eliminate interfering factors, the research team identified Cu(100) grain boundaries as the key sites driving efficient C2+ production. Advanced characterization and theoretical calculations confirmed these sites facilitate asymmetric C–C coupling between *CHO and *CO intermediates, providing critical insights for rational catalyst design.
To achieve compact yet high-quality imaging, scientists in Tongji University and Stanford University, have developed a neural array meta-imaging system that overcomes long-standing optical trade-offs. The 2.76-mm single-metalens camera captures real-time full-color video at 25 Hz with image quality comparable to commercial lenses. This breakthrough paves the way for ultrathin, high-performance, and intelligent imaging systems, advancing next-generation optical technologies for mobile, industrial, and aerospace applications.
Chinese chemists boost lignin’s sun protection factor from 5 to 66 and cut colour darkness by one-third through controlled radical grafting and TiO₂ nano-loading, offering a biodegradable alternative to petrochemical filters.
Reporting in the Journal of Bioresources and Bioproducts, researchers show that atom-transfer radical polymerisation couples waste-pulp lignin with the commercial UV absorber MBBT, producing sub-micron spheres that remain stable after three hours of intense ultraviolet irradiation.
A Canadian team turned 23,000 mating types into a materials library, showing nuclear-mitochondrial combos double film strength or ductility depending on cross-linker choice.
Writing in the Journal of Bioresources and Bioproducts, researchers report the first systematic screen of wild fungal genotypes for pure mycelial materials, proving that strain choice can outperform process tweaks in green fabrication.
Italian scientists melt-blend lignin scorched in a gliding-arc tornado into polypropylene, doubling toughness and keeping 98 % of strength after two re-extrusions without any chemical compatibilizer.
Reporting in the Journal of Bioresources and Bioproducts, researchers show that a 30-second argon-plasma whirl cuts hydroxyl groups on lignin by one third, spawns phenoxy radicals and forges stronger bonds with polypropylene, yielding recyclable, high-performance green composites.
