Abstract: A method for making an electrocatalyst containing manganese oxide nanoparticles present on carbon obtained from Albizia procera (MnOxNPs-C) for electrochemical water oxidation. The method includes a thermal decomposition and forms a product with specific morphological variations, including crystalline structure, elemental composition, and chemical compatibility. The manganese oxide nanoparticles are well dispersed over the carbon. The amount of manganese oxide nanoparticles increases by increasing the amount of precursor. Single-phase formation of the Mn3O4, and Mn3O4 along with MnO phase occurs at low and high amount of the precursor materials, respectively. The electrocatalyst can be used for the purpose electrolytic water splitting.

Abstract: A supported catalyst having rhodium particles with an average diameter of less than 1 nm disposed on a support material containing magnetic iron oxide (e.g. Fe3O4). A method of producing the supported catalyst and a process of reducing nitroarenes to corresponding aromatic amines employing the supported catalyst with a high product yield are also described. The supported catalyst may be recovered with ease using an external magnet and reused.

Abstract: A method of recovering a hydrocarbon from a reservoir, whereby an oil recovery formulation containing carboxylic acid functionalized-pyrolyzed date leaf particles is injected into the reservoir, and the hydrocarbon is collected from the reservoir. The carboxylic acid functionalized-pyrolyzed date leaf particles are obtained sequentially from date leaves by cutting the date leaves and drying, pulverizing in the presence of a metal bicarbonate, pyrolyzing at 700 to 1,000° C., and treating the product thus obtained with an acid solution that includes nitric acid to introduce carboxylic acid functional groups.

Abstract: A silanized ITO electrode modified with ITO nanoparticles is described. ITO nanoparticles of cubic and semispherical shapes are immobilized on a silanized ITO film. The electrode may be used in an electrolytic cell to detect aqueous sulfide with a 0.5-1.4 μM limit of detection. The electrode shows high specificity towards aqueous sulfide and a high reproducibility in measurement.

Abstract: Monodisperse carboxylate functionalized gold nanoparticles comprising a capping agent layer of pamoic acid and colloidal suspensions thereof are disclosed. These gold nanoparticles have an average particle size of greater than 15 nm or less than 8 nm and demonstrate significant fluorescent properties. In addition, a method for the size controlled preparation of these monodisperse carboxylate functionalized gold nanoparticles wherein pamoic acid acts as both a reducing and capping agent and wherein the size of the particles can be controlled by the pH of the process is disclosed. In addition, a method for the size controlled preparation of these monodisperse carboxylate functionalized gold nanoparticles utilizing seed mediated growth is disclosed.
