Fabrication and H2S gas sensitive performance of NiO ultrathin film encapsulated VO2(A) nanowire core-shell heterojunction structure

This study demonstrates that a NiO ultrathin film encapsulated VO2(A) nanowire core-shell heterojunction, fabricated via chemical precipitation and annealing with a 1:0.5 precursor molar ratio, achieves high sensitivity and rapid response/recovery for H2S gas detection at 100°C due to the synergistic effects of the heterojunction and NiO's catalytic activity.

A Novel Method for Determining Phase-Specific Microhardness from Non-targeted Automated Testing of Fine-grained Multiphase Structures

This paper proposes a novel experimental-simulation methodology that utilizes non-targeted microhardness measurements and virtual testing to accurately determine intrinsic phase-specific microhardness in fine-grained multiphase alloys by analyzing the statistical relationship between indentation size and grain morphology.

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.
