A stainless steel wire may be platinized using electrophoretic deposition (EPD) method and then may be coated by polyaniline/multiwalled carbon nanotube (PANI/MWCNT) nanocomposite by electrochemical polymerization (EP). The resulting fiber may be used for headspace solid-phase microextraction (HS-SPME) of residual solvents (benzene, toluene, ethylbenzene and xylene, BTEX) in commercial pharmaceutical drugs, followed by gas chromatography-flame ionization detection (GC-FID).

An artificial photosynthesis module is used for decomposition of an electrolytic aqueous solution into hydrogen and oxygen by light. The artificial photosynthesis module has an oxygen generation electrode having a first protrusion and a first recess alternately arranged thereon, and a hydrogen generation electrode having a second protrusion and a second recess alternately arranged thereon. The hydrogen generation electrode and the oxygen generation electrode are in contact with the electrolytic aqueous solution, and at least one electrode of the hydrogen generation electrode or the oxygen generation electrode includes a conductive layer and a photocatalyst layer provided on the conductive layer. The hydrogen generation electrode and the oxygen generation electrode are arranged side by side, the second protrusion of the oxygen generation electrode faces the first recess of the hydrogen generation electrode in an arrangement direction, and the first protrusion faces the second recess in the arrangement direction.

The problem with healthcare today is that clinicians are required to make time sensitive decisions without a complete, comprehensive, objective and easily accessed picture of a patient's overall condition. Healthcare data lives in multiple, unconnected silos and paper based files. The result to hospitals is lost revenue, administrative inefficiencies and increased labor costs. The tool as described above solves for these challenges by providing real time, accumulated, analyzed and scored data and corresponding and relevant workflows that can be accessed at the point of care through claim payment and finalization.

A new combustible gas is produced by reacting a gas mixture consisting of 90%-10% of carbon dioxide and 10%-90% of OHMASA-GAS under a pressure of 0.1 MPa-10 MPa at a temperature of 5° C.-50° C.
摘要:
A method is provided for an electrochemical synthesis of ammonia in alkaline media. The method electrolytically converts N2 and H2 to NH3 in an electrochemical cell comprising an anode, a cathode, and an alkaline electrolyte. The method includes exposing an anode to a H2-containing fluid, wherein the anode is active toward adsorption and oxidation of H2; exposing a cathode to a N2-containing fluid, wherein the cathode is active toward adsorption and reduction of N2 to form NH3; and applying a voltage between the anode and the cathode so as to facilitate adsorption of hydrogen onto the anode and adsorption of nitrogen onto the cathode; wherein the voltage is sufficient to simultaneously oxidize the H2 and reduce the N2. The electrolytic method is performed with the H2 and N2 pressures from about 10 atmospheres (atm) to about 1 atm; and at temperatures from about 25° C. to about 205° C.
