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.

摘要:Described herein are catalyst support materials for use in synthesizing ammonia (NH 3 ) from nitrogen gas (N 2 ) and hydrogen gas (H 2 ) and methods of making the same. The support material may comprise (MgO) x (BaO) y (Al 2 O 3 ) z and/or (MgO) x (SrO) y (Al 2 O 3 ) z , on which an ammonia synthesis catalyst such as ruthenium is dispersed. When the catalyst support material comprises (MgO) x (BaO) y (Al 2 O 3 ) z , x is from about 0.05 to about 0.7, y is from about 0.05 to about 0.6, and z is from about 0.3 to about 0.5. When the catalyst support material comprises (MgO) x (SrO) y (Al 2 O 3 ) z , x is from about 0.4 to about 0.7, y is from about 0.05 to about 0.5, and z is from about 0.05 to about 0.3.

摘要:A compound of the formula (I), wherein R 1 is C 1-4 alkyl or phenyl, is prepared by reacting a dicyanomethanide of the formula: M r n + [CH(CN) 2 ] rÌ… n (II), wherein M is an alkali or alkaline earth metal and r is 1 or 2, with carbon monoxide to obtain a dicyanoethenolate of the formula: M r n + [(NC) 2 C=CH–O] rÌ… (III), which is acylated to obtain an acyloxymethylenemalononitrile of the formula: (NC) 2 C=CH–OCOR 2 (IV), wherein R 2 is C 1-4 alkyl, which in turn is reacted with an amidine of the formula (V) to obtain the 4-amino-5-cyanopyrimidine of the formula (I). The compound of formula (I), wherein R is methyl, is an intermediate in a synthesis of thiamin (vitamin B 1 ).

发明人:YING JACKIE Y; ZARUR ANDREY
权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:The present invention relates to a method of producing particles having a particle size of less than 100 nm and surface areas of at least 20 m 2 /g where the particles are free from agglomeration. The method involves synthesizing the particles within an emulsion having a 1-40% water content to form reverse micelles. In particular, the particles formed are metal oxide particles. The particles can be used to oxidize hydrocarbons, particularly methane.
