Researchers developed a self-adaptive Cu–Co catalyst that converts nitrate pollutants into green ammonia, achieving high activity and selectivity. The catalyst's adaptive reconstruction strategy enables it to continuously evolve into its most active state during operation.
A study published in PNAS found that the human brain's resilience process doesn't peak immediately after a stressful event; instead, it manifests in a distinct 'resilience window' about an hour later. This delayed neural shift distinguishes resilient individuals and offers a new time-target for interventions.
Researchers have developed a new method for generating hydrogen using gas-atomized Ca–Mg eutectic alloys. When added to water, these powders produce hydrogen at room temperature with high efficiency and controllability, making them an attractive candidate for portable hydrogen supply devices and emergency power units.
The study successfully visualizes the anthracene [4+4] photocycloaddition reaction for the first time, demonstrating controllable, trans-scale photoinduced reaction systems. Direct visualization of intermediate states via single-crystal X-ray diffraction reveals a solid solution consisting of monomers and dimers.
