权利人:UMICORE AG & CO KG
摘要:The invention provides methods for a one-pot synthesis of molecular sieves of the CHA-type. The method uses molecular and non-molecular sieves as sources of silicon and aluminum. A first OSDA is selected from tetraethylenepentamine (TEPA) and triethy-lenepentamine (TETA). The synthesis mixture comprises a first metal selected from copper, iron and zinc. Optionally, the synthesis mixture may furthermore comprise a second OSDA and/or a second metal selected from manganese, cesium, magnesium, calcium, strontium, barium, yttrium, titanium, zirconium, niobium, iron, zinc, silver, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and mixtures thereof. The molecular sieves of the CHA-type obtainable by the method can be used as SCR-catalytically active substances for the removal of nitrogen oxides from exhaust gases of combustion engines.

标题:Microemulsion template assisted synthesis of cadmium-free near-infrared quantum dots based on i-iii-vi ternary semiconductors
发明人：WANG JUN

摘要:A method for making ternary core-shell semiconductor nanoparticles includes providing an emulsion including droplets dispersed in a continuous phase of a non-polar solvent. The droplets include a solution of ions of a Group I element and ions of a Group III element in a polar solvent, and are encapsulated by an interfacially active material. The emulsion is exposed to ions of a Group VI element to cause a reaction, thereby forming nanoparticles in the droplets. The nanoparticles in the droplets are with a first precursor to grow a shell on the nanoparticles, thereby forming core-shell nanoparticles. The core-shell nanoparticles are extracted from the emulsion; thermally annealed; and reacted with a second precursor to further grow the shell on the nanoparticles, thereby forming ternary core-shell semiconductor nanoparticles.

标题 :Synthesis of Alloyed Nanocrystals in Aqueous or Water-Soluble Solvents

摘要:The present invention relates to nanocrystals and methods for making the same; in particular, the invention relates to ternary or higher alloyed nanocrystals and methods for making such structures in aqueous or water-soluble solvents. In certain embodiments of the invention, methods of preparing ternary or higher alloyed nanocrystals involve providing at least first, second, and third nanocrystal precursors (e.g., NaHSe, ZnCl 2 , and CdCl 2 ) and forming nanocrystal structures in an aqueous or water-soluble solvent. In some cases, nanocrystal precursor solutions may also include a water-soluble ligand (e.g., glutathione, GSH). As such, ternary or higher alloyed nanocrystals (e.g., Zn x Cd)— x Se) comprising the at least first, second, and third nanocrystal precursors may be formed, and the water-soluble ligand may coat at least a portion of the surface of the ternary or higher alloyed nanocrystal. Advantageously, methods for forming nanocrystals described herein can be performed at low temperatures (e.g., less than 100 degrees Celsius), and, in some embodiments, do not require the use of organic solvents. The present inventors have applied these methods to prepare blue-emitting nanocrystals with emissions that are tunable between 400-500 nm, and with quantum yields of greater than 25% in aqueous solution. These nanocrystals may be highly water soluble and can be used in a variety of applications, including those involving cell culture, sensing applications, fluorescence resonance energy transfer, and in light-emitting devices.

标题:Synthesis of polyether polyols based low dosage gas hydrate inhibitors using double metal cyanide catalyst

摘要:A series of different metals (Zn/Fe/Co/Sn/Mg/La/Al/Cr) based double metal cyanide (DMC) catalyst is disclosed herein. Benzene-1,3,5-tricarboxylic acid (BTC) is incorporated as an organic complexing agent (CA) in the DMC catalyst. The DMC catalysts prepared with BTC and its derivatives as CAs are highly active towards ring opening polymerization (ROP) of propylene oxide (PO) and imparts heterogeneity as compared to the DMC prepared without any CA. The polyether polyols (PEPOs) with controlled molecular weight (Mw), polydispersity index (PDI), hydroxyl value (OH), and iodine value (I2) are produced using a DMC catalyst. PEPOs of the present invention relate to low-dosage gas hydrate inhibitors (LDHIs) utilized to mitigate/manage the formation, growth, and deposition/agglomeration of gas hydrate crystals in oil and gas production pipelines (especially applicable to deep and ultra-deep developments), and drilling or fracturing operations during natural gas hydrate exploration.
