Porous nitrogen-doped and nitrogen-free carbon materials possessing high specific surface areas (– m2 g−1) were used for deposition of Ni by impregnation with nickel acetate followed by reduction. The nitrogen-doped materials synthesized by decomposition of acetonitrile at , , and K did not differ much in the total content of incorporated nitrogen (4–5 at%), but Author: Alina D.

Manganese oxides with rich redox chemistry have been widely used in (electro)catalysis in applications of energy and environmental consequence. While they are ubiquitous in catalyzing the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR), redox processes occurring on the surface of manganese oxides are poorly understood. We report valence changes at OER- and ORR-relevant Cited by: Begin learning about matter and building blocks of life with these study guides, lab experiments, and example problems. Science View More.

The solubilities of nitrogen in liquid iron and liquid Fe-C, Fe-Si and Fe-Mn alloys were measured at °C. The results on liquid iron confirmed that Sievert's law was followed in the range. The rates of absorption of nitrogen in liquid iron and liquid iron alloys were measured for inductively melted iron under pure nitrogen at °C.
In the search for a corrosion-resistant high-uraniumcontent alloy for use as core material in high-temperature-water-moderated reactors, the corrosion of binary and ternary U alloys was studied in water at and deg F. Alloys contaiiifng less than 40 wt,% Zr additions completely oxidized upon short exposure at deg F, whereas 50 plus wt.% alloys exhibited relatively low corrosion rates.

Lawrence Arnold Greenberg has written: 'A study of the rates of absorption of oxygen and nitrogen in liquid iron and liquid iron alloys' -- subject(s): Metallurgy, Oxygen, Iron, Gases in metals. Decarburization is a loss of carbon in the surface-adjacent zone of the material (Gunnarson, ).Contributing factors are high temperatures and large amounts of oxygen in the atmosphere.
At higher temperatures, the diffusion rate of carbon is so large that longer annealing times lead to decarburization. The absorption cross section for thermal neutrons is barn for zirconium, which is much lower than that for such common metals as iron ( barn) and nickel ( barn).
The composition and the main applications of common reactor-grade alloys are summarized below. These alloys contain less than % of iron and chromium and –% oxygen. The iron (Fe) electrodeposition–electrochemical dissolution has been employed on nitrogen-doped carbon material (P-PI) prepared via multi-step pyrolysis of a polyimide precursor to achieve the introduction of Fe species, and its influence on the oxygen reduction reaction (ORR) is investigated by cyclic and rotating ring-disk electrode voltammetry in M by: A new method, entitled chemical potential programmed reaction, for determining the physicochemical properties of iron ammonia synthesis catalyst has been proposed.
Two model reactions were applied: nitriding of the iron catalyst and reduction of the obtained nitrides. Measurements of the rates of those reactions were carried out at °C in a differential tubular by: 4. Copper and copper alloys undergo corrosion in fuels probably according to the same mechanism as iron and iron alloys.
However, the corrosion processes taking place on copper are less destructive and slower – corrosion pits, if present all, are limited to extreme conditions; corrosion is usually manifested by discoloration of the metal or Cited by: 2. Organic corrosion inhibitors are one of the five ways, besides material selection, design, cathodic protection and coatings, to protect materials against corrosion.
Corrosion is an ubiquitous phenomena that deteriorates all materials, metals, plastics, glass and concrete. The costs of corrosion are tremendous and amounts to % of gross domestic product (GDP) in by: 4.

Solubility: amount of solute required to form a saturated solution. More pressure will increase the solubility of gas in a liquid.
Increasing temperature will decrease solubility of a gas in liquid. • Corrosion of iron-base, copper-base, nickel-base, etc. alloys in the chemical process industry • Corrosion of automobile exhaust systems by direct reaction of the metal with high-temperature gases and by condensation of water and absorption of the oxides of.
