Abstract Nutritional and contaminant stressors influence organismal physiology, trophic interactions, community structure, ecosystem-level processes; however, the interactions between toxicity elemental imbalance in food resources have been examined only a few ecotoxicity studies. Integrating well-developed ecological theories that cross all levels of biological organization can enhance our und...
Superoxide Dismutase-Based Third-Generation Biosensor for Superoxide Anion Electrochemical Immunoassay Moving into the Fast Lane Characterization and Reactions of Previously Elusive 17Electron Cations: Electrochemical Oxidations of (C H )Cr(CO) and (C H )Co(CO) in the Presence of [B(C F ) ] Although chemical redox reagents can be highly selective, many produce toxic b y p r o d u c t s .

A new type of nonstoichiometric rutile titanium dioxide (TiO2) film with around 15 at% oxygen vacancies homogeneously distributed throughout the bulk was prepared. The resultant films, when used as a photoelectrode, showed a photoelectrochemical water splitting activity 1.7 times that of stoichiometric TiO2 at a bias of 0.9 V vs. Ag/AgCl. This is believed to result from the synergistic effect o...
The remarkable stoichiometric flexibility of hydroxyapatite (HAp) enables the formation of a variety of charged structural sites at the material's surface which facilitates bone remodeling due to binding of biomolecule moieties in zwitterionic fashion. In this paper, we report for the first time that an optimized biomedical grade silicon nitride (Si3N4) demonstrated cell adhesion and improved o...
The copper-catalyzed N-arylation of amides, i.e., the Goldberg reaction, is an efficient method for the construction of products relevant to both industry and academic settings. Herein, we present mechanistic details concerning the catalytic and stoichiometric N-arylation of amides. In the context of the catalytic reaction, our findings reveal the importance of chelating diamine ligands in cont...
