A NaBH4-reduced Cu–Pd/TiO2 catalyst was demonstrated to be superior to monometallic counterparts for the selective hydrogenolysis of dilute aqueous glycerol to 1,2-propanediol, achieving a 63.38% conversion under optimized reaction conditions while highlighting the influence of operating variables on product distribution.
This study demonstrates that copper nanoparticles (4.5 wt.%) synthesized on gamma alumina and natural clinoptilolite zeolite both effectively degrade Congo Red dye via photocatalysis, with the alumina-supported catalyst exhibiting superior performance attributed to its enhanced mesoporosity and a higher proportion of smaller 2 nm nanoparticles.
This study introduces a flexible, lead-free liquid metal amalgam composed of a Ga-In-Sn matrix and up to 27 dispersed metallic elements that eliminates weak absorption windows across the 1–100 keV range, achieving 39% higher shielding efficiency than lead while maintaining performance under extreme deformation.
This study demonstrates the successful green synthesis of iron oxide nanoparticles using rice husk and orange peel extracts and residues (RHOPTNPs), which effectively remove ciprofloxacin and ibuprofen from aqueous solutions through a spontaneous, chemisorption-driven monolayer adsorption mechanism.
This study demonstrates that calcium ions significantly impair the antibacterial efficacy and stability of catechol-containing phytochemicals through chelation, highlighting the critical need to select non-catechol alternatives or account for these interactions when designing calcium-rich bone and dental biomaterials.
This study demonstrates that coupling a vertical flow constructed wetland with photoelectro-Fenton treatment effectively removes over 99% of ketoprofen from real wastewater, significantly reduces toxicity, and offers a cost-effective, sustainable strategy for advanced wastewater polishing.
This study utilizes in-orbit experiments on the China Space Station to demonstrate that microgravity significantly inhibits the growth and metabolic activity of *Aspergillus brasiliensis* on silicone rubber, resulting in reduced organic acid secretion and lower material degradation compared to ground controls, thereby providing critical insights for spacecraft material protection.
This study introduces a cation-intercalation strategy to synthesize a new class of primary explosives, (Et4N)2[Cu8(N3)18], which overcomes the traditional safety–energy trade-off of copper azide by achieving superior electrostatic safety and initiation efficiency compared to the industry-standard lead azide.
Through structure-based optimization of the lead compound LRH-0003 targeting the SARS-CoV-2 Mac1 domain, researchers discovered the novel derivative L-5-A, which exhibits significantly improved binding affinity driven by specific hydrogen bonding and hydrophobic interactions, alongside favorable drug-like properties suitable for further antiviral development.
This study demonstrates that an aqueous beetroot extract, which alone shows limited or negative inhibition, synergistically enhances corrosion protection for carbon steel in borewell water when combined with Zn²⁺, achieving an 84% inhibition efficiency through the formation of a protective anodic film confirmed by gravimetric, electrochemical, and surface-morphological analyses.
