A synthesis process for forming nanodendrites. The nanodendrites are utilized in a process to form a heterojunction catalyst. Nanodendrites may include PtRunanodendrites that can be oxidized through annealing to form PtRuO. One heterojunction catalyst comprises PtRuOon a carbon support.

Scalable Pt cluster and RuO2 heterojunction anode catalysts

A method for forming a melamine-modified electrode that includes providing a metal based electrode and patterning a surface of the metal-based electrode by contacting the electrode with a melamine solution to form a patterned metal-based electrode. The patterned metal-based electrode includes metal sites blocked with melamine molecules and metal sites which are not blocked such that the metal-based electrode selectively adsorbs Oinstead of at least one of sulfate, phosphate, or sulphonate. A range of 20% to 40% of the metal sites are blocked with melamine molecules.

Melamine modification of fuel cell electrodes

An alternative grid energy storage system is described herein. In one embodiment, an electrochemical cell comprises a high specific surface area cathode (e.g., a cathode comprising a carbon nanofoam paper, a carbon nanotube mesh, a particulate carbon material, electrolytic manganese dioxide, or a manganese dioxide film), a zinc or lead anode (e.g., Zn or Pb foil), a selective ion-conductive separator that does not conduct zinc ions (e.g., a NAFION sulfonated tetrafluoroethylene based fluoropolymer-copolymer separator) between the anode and the cathode, and an aqueous electrolyte comprising a manganese salt (e.g., aqueous manganese sulfate) contacting the electrodes and the separator. A battery comprising two or more of the electrochemical cells electrically connected together in series, parallel, or both, also is described.

Aqueous manganese ion battery

An electrochemical filter system is provided that can produce an ultra-clean electrolyte solution. The filter uses a working electrode with binding sites that adsorb impurities present in the electrolyte solution using a pseudocapacitive process.

A stationary probe having a probe holder and a probe with a probe tip. The stationary probe may be part of a stationary probe rotating disk electrode wherein the stationary probe has a passage therethrough for rotatably receiving a rotating disk electrode comprising a rotating shaft, rotatable about a longitudinal axis, and having an electrode portion extending therefrom configured to receive an electrode. The stationary probe rotating disk electrode may be part of an analytical system wherein the probe tip includes a capillary entrance spaced apart from the electrode and connected to an analyte flow path.

Stationary probe rotating disk electrode

A process includes patterning a surface of a platinum group metal-based electrode by contacting the electrode with an adsorbate to form a patterned platinum group metal-based electrode including platinum group metal sites blocked with adsorbate molecules and platinum group metal sites which are not blocked.
