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 regenerating noble metal catalyst for the synthesis of hydrogen peroxide according to the anthraquinone process
发明人：SCHREYER GERD; THEISSEN FERDINAND; WEIBERG OTTO; WEIGERT WOLFGANG
权利人:DEGUSSA
摘要:In situ regeneration of noble metal catalysts for the synthesis of hydrogen peroxide by the anthraquinone process is provided by employing as the working solution coming from the extraction or desorption step and being introduced into the hydrogenation step a solution which contains at least 250 mg/liter of hydrogen peroxide, to thereby completely regenerate the noble metal catalyst by full capacity of the hydrogenation step.

权利人:RIMER JEFFREY D; MALDONADO MIGUEL; OLEKSIAK MATTHEW D; UNIV HOUSTON SYSTEM
摘要:Methods of controlling crystal polymorphism in organic-free synthesis of Na-Zeolites and the zeolite crystals formed using those methods are provided. The methods disclosed herein create certain types of zeolite crystals more efficiently than other previously known methods. The methods also create certain types of zeolite crystals in a form and concentration not previously disclosed. The methods disclosed herein generally comprise using solutions with varying ratios of silicon (Si), aluminum (Al), hydroxide (OH), and water. Some implementations of the invention disclosed include efficient methods of producing nearly pure cancrinite (CAN), methods of obtaining sodalite in solutions with a high Si/Al ratio, and a method of forming thin, platelet-like ANA crystals with a width of less than about 1 μm and a length of at least about 3 μm.
