Researchers at The University of Osaka have developed a non-precious metal catalyst for the efficient hydrogenation of biomass-derived furfural to valuable tetrahydrofuran-based compounds under mild conditions. The catalyst, consisting of nickel carbide nanoparticles supported on alumina, achieved 90% furfural conversion under ambient hydrogen pressure. This result will help advance the development of energy-efficient, cost-effective processes for the conversion of biomass to valuable materials.
Scientists developed a smartphone-compatible ethanol sensor using a metal–organic framework called Cu-MOF-74. The sensor visually detects ethanol concentrations across a wide range, with no electronics or lab tools required. This technology has promising applications in environmental monitoring, healthcare, industrial processes, and alcohol breath analysis.
Researchers in Japan have developed an AI model that objectively evaluates atopic dermatitis (AD) severity using smartphone images shared by patients on the country’s largest online AD platform. This technology could help patients monitor their condition more precisely at home and support timely treatment decisions.
Higher maternal selenium levels during pregnancy were associated with a lower risk of streptococcal infections in children, suggesting a potential protective effect.
