Abstract: Processes and systems for oxidation of a hydrocarbon reactant to generate an oxidized hydrocarbon product may include: contacting a water oxidation electrocatalyst with the hydrocarbon reactant and water in the presence of a non-aqueous solvent; wherein an anodic bias is applied to the water oxidation electrocatalyst, thereby generating the oxidized hydrocarbon product; and wherein the water oxidation electrocatalyst comprises one or more transition metals other than Ru. Optionally, the water is provided in the non-aqueous solvent at a concentration less than or equal to 0.5 vol. %. Optionally, the magnitude of the anodic bias is selected to generate the oxidized hydrocarbon product characterized by selected product distribution.

Abstract: In an aspect, a redox flow battery comprises a catholyte and an anolyte; wherein at least one of said catholyte and said anolyte is a metal-coordination complex, said metal-coordination complex comprising: (i) a metal; (ii) one or more first ligands coordinated with said metal atom, wherein each of said first ligands is independently a Lewis basic ligand; and one or more second ligands associated with said one or more first ligands, wherein each of said second ligands is independently a Lewis acid ligand; and a nonaqueous solvent, wherein said catholyte, said anolyte or both are dissolved in said nonaqueous solvent. One or more first ligands may be provided in a primary coordination sphere of said metal-coordination complex and one or more second ligands may be provided in a secondary coordination sphere of said metal-coordination complex.

Abstract: Methods and compositions modulate the activity of electrically excitable cells. Photovoltaic compounds which, upon exposure to light energy, increase or decrease the electrical activity of cells. These supplement and/or replace of vision based on the conversion of light energy to electrical energy within certain cells of the visual system. A “patch” or bridge to circumvent one or more defective, damaged, or diseased cells in the visual system. Additionally, in several embodiments, subjects with normal vision can benefit from the methods, compositions, systems, and/or devices disclosed herein as normal visual acuity can be heightened. The exposure induces an energy (e.g., a receipt of light energy, conversion to electrical energy, and passage of that electrical energy) from the photovoltaic compound to the cell, thereby altering the transmembrane potential of the cell and/or the opening of one or more ion channels, thereby modulating the activity of the electrically excitable cell.

Abstract: Metallocorrole complexes of third row transition metals (see Formula I below) may be used as therapeutic agents, catalysts, components of oxygen detectors, and components of light emitting diodes. In particular, metallocorrole complexes of third row transition metals may be used as improved photosenitizers in photodynamic therapy; as improved catalysts in aziridination, epoxidation, and water splitting reactions; as improved in vivo imaging agents; and as improved components in the emissive layer of OLEDs. Due to their strongly sigma-donating nature, corroles are able to stabilize third row transition metals in high oxidation states. Third row transition metals are significantly more electropositive than their first and second row counterparts and may therefore act as improved catalysts.
