HPLC-DAD Profiling and Molecular Docking Insights into Lantana camara L. Flower Extract from Northwestern Algeria: Verbascoside and Luteolin as Potent Inhibitors of Human Pancreatic α-Amylase.

This study identifies Luteolin, a rigid flavone abundant in *Lantana camara* flowers from Northwestern Algeria, as a superior inhibitor of human pancreatic α-amylase compared to the more flexible Verbascoside and acarbose, due to its ability to overcome entropic penalties and form precise interactions with the enzyme's catalytic triad.

Study on the Synergistic Inhibition Mechanism and Thermal Stability of a Composite Inhibitor (Aluminum Hydroxide–Ammonium DihydrogenPhosphate–Sodium Polyacrylate) for the Spontaneous Combustion of Long-Flamed Coal

This study elucidates the synergistic inhibition mechanism and enhanced thermal stability of a ternary composite inhibitor (aluminum hydroxide, ammonium dihydrogen phosphate, and sodium polyacrylate) for long-flamed coal, demonstrating that the optimal 5:1:1 formulation significantly suppresses spontaneous combustion by physically insulating the coal, chemically passivating active sites, and sealing micro-cracks to reduce exothermic heat and increase oxidation activation energy.

Density and molar volume of CaO–SiO2–FeO melts measured by electrostatic levitation aboard the International Space Station

Using the Electrostatic Levitation Furnace aboard the International Space Station, researchers measured the densities and molar volumes of CaO–SiO2–FeO melts under microgravity, revealing that density increases with FeO content while molar volume generally aligns with additive-model predictions despite slight deviations at higher FeO concentrations.

Clamp-like side-arm-functionalized calixarenes reinforce molecular cage confinement for damp-heat operationally durable perovskite photovoltaics

This study enhances the long-term damp-heat stability of high-efficiency perovskite solar cells by incorporating a clamp-like side-arm-functionalized calixarene derivative into the hole transport layer, which effectively confines lithium ions to prevent their migration and hydration-induced corrosion while achieving certified power conversion efficiencies of up to 27.14%.
