Two new species of Ziminellia Nihei & de Carvalho from China (Diptera: Muscidae), with new combinations and key to species

During our study of the genus Ziminellia (Diptera, Muscidae) from China, two species are recognized as new to science, Z. quadrangula Xue & Nihei, sp. nov. and Z. yunnanensis Xue & Zhang, sp. nov., and their descriptions, illustration and diagnoses are given. Furthermore, five ne...

Continuous Feedback at Scale: Closing the Instruction–Response–Feedback Loop in a Large Physical Chemistry Laboratory Course

Abstract The classical structure of physical chemistry laboratory courses often relies on delayed, report-based assessment, which can hinder conceptual understanding and student engagement, particularly in large classes. In this study, we report the redesign of an undergraduate p...

Synthesis, characterization and molecular docking of 4-(1-(1H-benzo[d]imidazol-2-ylimino)ethyl)benzonitrile and amino acid alanine and its metal complexes

The transition metal ion complexes with mixed ligands have highly varied biological characteristics. Schiff bases comprising amino acids and azomethine are excellent building blocks for ternary complexes. To synthesize novel Metal(II) complexes, the interaction of two ligands, 4-...

From Seaweed to Corrosion Inhibitor: A Multi-MethodValidation of λ-Carrageenan as a Non-Toxic Inhibitorunder Acidic Hydrodynamic Conditions

Abstract Corrosive processes are responsible for direct and indirect costs in industrial systems, which can be mitigated by corrosion inhibitors. The awareness of environmental risks has motivated sustainable approaches, such as naturally derived biopolymers, due to low toxicity...

Peptidomic Characterizationand Functional Propertiesof Goat and Cow Milk Kefir before and after In Vitro Digestion

Abstract Kefir is a fermented beverage produced from goat or cow milk. This study evaluated the bioactive potential and peptidomic profile of kefirs from both species before and after in vitro digestion. Peptides from undigested, gastric, and intestinal phases were characterized...
