摘要:The invention provides methods for the synthesis of iron oxide nanoparticles and the particles obtainable by these methods. The particles can be used as tracer materials for magnetic particle imaging and for Magnetic Particle Spectroscopy (MPS). The method for the synthesis of these particles comprises the steps: (i) dissolving at least one water-soluble iron salt and at least one water-soluble stabilizer in water to form a reaction batch, (ii) adding at least one base to the reaction batch to yield a pH of 10 to 13, and (iii) exposing the reaction batch to a reaction temperature T R for a defined period of time DT, wherein T R ≥ 110°C, to obtain the iron oxide nanoparticles.

标题:Chemical synthesis of conducting polypyrrole using uniform oxidant/dopant reagents
发明人：WARREN LESLIE F; STRAUSS DENNIS R
权利人:ROCKWELL INTERNATIONAL CORP
摘要:A method for producing oxidant/dopant reagent solutions which comprises reacting a basic ferric carboxylate, preferably basic ferric acetate, with an alkyl or aryl sulfonic acid, e.g., benzenesulfonic acid, to produce the corresponding ferric sulfonate in solution. Oxidant/dopant solutions can also be prepared containing cupric or ceric sulfonates. The oxidant/dopant solution is employed in situ for reaction with a pyrrole to produce electrically conductive polypyrrole. A porous substrate, such as fiberglass cloth, can be dipped in the oxidant/dopant solution, dried and then treated with a pyrrole to produce an electrically conductive polypyrrole deposit in the interstices of the substrate.

摘要:Disclosed herein are catalysts containing metallic nanoparticles and a porous matrix, and methods of making and using thereof. The metallic nanoparticles in the catalyst are embedded and homogeneously distributed in the porous matrix. The metallic nanoparticles are nanoparticles of a metal alloy. The porous matrix is a carbon-based carbon, such as nitrogen-doped carbon, and has a high surface area. The methods of making the catalysts include heating a mixture containing at least two metal precursors to form the catalyst. The disclosed catalysts can be used for catalyzing ammonia synthesis, which includes exposing a mixture of nitrogen gas and hydrogen gas to the catalyst. The disclosed method can increase the single-pass and/or equilibrium ammonia concentration and/or the ammonia production rate in a given reactor under the same reaction conditions, relative to a corresponding single metal catalyst or a commercially available catalyst for ammonia synthesis, such as the industry benchmark catalyst KM1.
