CO2 reduction to storable fuels or valuable chemical products provides a carbon-neutral cycle that can mitigate the rapid consumption of fossil fuels and increasing CO2 emissions. Although solar-driven CO2 reduction holds great promise for sustainable energy, the role and control of atomic-level active sites in governing intermediate formation and conversion pathways remains poorly understood. Here, we demonstrate a capped VLS growth method employed to grow continuous ultrathin alloy films of molybdenum vanadium sulfide with sulfur vacancies, i.e., Svac-Mo1-xVxS2. The findings indicate a correlation between the density of Svac and the vanadium concentration, leading to the formation of V–Svac pairs, which serve as the active sites for CO2 reduction under solar light with water.

Carbon-based batteries could become safer, more durable, and more powerful by following this new method that fundamentally redesigns how fullerene molecules are connected.

A joint team from UOsaka has uncovered the core principles of the loss maximization in rotor-driven gas-liquid two-phase flows. Performing numerical simulations on the supercomputer "SQUID", they identified the causes as direct collisions between the rotor and the liquid surface and pressure imbalances around the rotor. The findings suggest that, in a resonant state, the enhanced fluid motion is drawn toward the front of the rotor, and the flow instability is intensified behind it. The insights from this research would open the possibility of improving energy efficiency, enhancing reliability and lifespan, and providing new design guidelines for various industrial applications.

Slow earthquakes have been discovered to exhibit anomalously slow, long-lasting, and small slips, adjacent to regular earthquakes where we sometimes feel catastrophic vibration. However, no one knows the reason why they show such strange characteristics. In a study published in a scientific journal Nature Communications, researchers at The University of Osaka succeeded in experimentally reproducing the multiple features of slow earthquakes in the lab and suggested the grain-scale origin of them based on their direct observations.

Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, report in ACS Applied Nano Materials a new method to precisely measure nuclear elasticity—the stiffness or softness of the cell nucleus—in living cells. By employing a technique called Nanoendoscopy-AFM (NE-AFM), which inserts a nanoneedle probe directly into cells, the team revealed how cancer cell nuclei stiffen or soften depending on chromatin structure and environmental conditions. The findings provide fundamental insights into how the physical properties of cancer cell nuclei change during disease progression, highlighting their potential as biomarkers for diagnosis and treatment evaluation.
