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.

权利人:CHEVRON RES
摘要:A continuous cyclic electrolytic/carbon oxidation process wherein ferrous ion is oxidized at the anode and hydrogen is generated at the cathode of an electrolytic cell. The ferric ions produced at the anode are thereafter reduced to ferrous ions by contact with a solid carbonaceous material and the ferrous ions recycled for electrochemical reoxidation. The process produces partially oxidized organic products from the combustion process in high yield.

摘要:The synthesis of diamonds from salts of iron, manganese, calcium and magnesium is disclosed. Specifically, such synthesis, in a closed system, has involved carbonate and oxylate salts of the indicated metals. The reaction occurs at temperatures between 550° and 1600° C., higher temperatures requiring higher reaction pressures; specifically, the production of synthetic diamonds from ferrous carbonate is disclosed. The ferrous carbonate was packed into a platinum capsule which was sealed gas-tight, packed in unfired pyrophyllite, and heated for two hours at 900° C. while in a solid media press which applied a pressure of 40 kb (subsequently defined).

摘要:Catalyst for heterogeneous synthesis and more particularly for the preparation of oxygenated compounds from synthesis gas (substantially H2 and CO and CO2), based on the general formula: CuTiaMbAc in which M is at least one metal selected from the group consisting of chrome, manganese, cobalt, molybdenum, rhodium platinum and iron, A is an alkali or alkaline earth metal, a is comprised within 0.1 and 0.5 and b and c may vary between 0 and 0.2. Application of these catalysts for the preparation of higher alcohol mixtures (fuel grade) C1-C4 when b and c are zero, and C1-C4 (for about 50%) and C5-C10 (for the other 50%) when b and c are other than zero.
