摘要:The present disclosure relates to a method for external synthesis of rare-earth oxychloride and production of rare-earth metal or alloy. The method comprises the steps of adding hydrochloric acid (HCl) to a portion of a pre-defined weight of rare-earth oxide (RE2O3) converting the portion of RE2O3 to rare-earth chloride hydrate (RECl3.xH2O). The method further comprises mixing the residual rare-earth oxide (RE2O3) with the RECl3.xH2O and heating the mixture to a temperature exceeding 300℃ to obtain rare-earth oxychloride (REOCl). The method includes making the obtained REOCl to react directly with a reductant or mixture of reductant and alloying element in a temperature of 600℃ - 1400℃ for reducing the rare-earth oxychloride (REOCl) to rare-earth metal or alloy; and upon cooling, treating the reduced mass of rare-earth metal or alloy with water and dilute acid to remove reaction byproducts such as calcium chloride (CaCl2) and calcium oxide (CaO).

摘要:The present invention relates to an improved process for synthesis of DNA, RNA, proteins and like molecules, in particular cell-free enzymatic synthesis of DNA, preferably in large scale. The present invention relates to the synthesis of DNA using strand-displacement replication and the addition of nucleotides to the reaction mixture is controlled, thus controlling yield. The reaction mixture contains a starting amount of nucleotides, polymerase and DNA template, to which further nucleotides are supplied in a controlled manner.

摘要:Methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is nartower which renders a subsequent size-selected separation process superfluous.

标 题:Process for the synthesis of IZM-2 zeolite in the presence of a template, 1,6-bis(methylpiperidinium)hexane dihydroxide
发明人：MARTINEZ FRANCO RAQUEL; BATS NICOLAS
权利人:IFP ENERGIES NOW
摘要:A novel process is described for the preparation of a microporous crystalline solid, known as IZM-2 microporous solid or IZM-2 zeolite. This novel process consists of carrying out the synthesis of IZM-2 zeolite by conversion/transformation of a zeolite with structure type FAU in a fluorinated medium under hydrothermal conditions. In particular, said novel process consists of carrying out the synthesis of an IZM-2 zeolite in a fluorinated medium starting from a zeolite with structure type FAU used as the source of silicon and aluminium and a specific organic molecule or template comprising two quaternary ammonium functions, namely 1,6-bis(methylpiperidinium)hexane dihydroxide.
