权利人:BAYER IP GMBH; BAYER SOUTH EAST ASIA PTE LTD
摘要:The present invention relates to a method for the synthesis of semiconductor nanoparticles comprising elements of the groups IB, IIB, IIIA, IVA, VA or VIA of the periodic classification wherein the composition of the core nanoparticle is selected from the group consisting of IB-VIA, IIB-VIA, IIIA-VIA, IB-IIIA-VIA or IB-IIB-TVA-VIA, IIB-IIIA-VIA, IIB-TVA-VA or mixtures thereof, and at least one shell comprises elements of the groups IIB and VIA,, wherein in case the core composition is IIB-VIA the shell comprises at least a further element selected from the groups IB, IIIA, IVA or VA, using metal precursors comprising non- or weakly coordinating anions. It further relates to the consecutive process for the synthesis that includes first the preparation of a binary nanoparticle system then modified to make a ternary system which again can be further modified to make a quaternary system.

权利人:MOELLMANN EUGEN; HEINZE THOMAS; LIEBERT TIM; KOEHLER SARAH; SE TYLOSE GMBH & CO KG
摘要:The invention is directed to a simple and new method for the homogeneous synthesis of cellulose ethers. Ionic liquids are not only used as solvent, but also as reaction media for the homogeneous etherification of cellulose. The dissolved cellulose is treated with the etherification agent in the absence of organic and/or inorganic bases and in the absence and/or in the presence of moderate amounts of water. The obtained cellulose ethers show new distributions of substitution on the polymer chain, resulting in new properties and applications.

标 题 :Synthesis of metal oxynitrides using flame spray pyrolysis
发明人：SASMAZ ERDEM; CORDONNIER NICOLE; MEEKINS BENJAMIN; NAGLIC JENNIFER
权利人:UNIV SOUTH CAROLINA
摘要:The present disclosure is directed to methods for producing metal oxynitrides using flame synthesis. Embodiments of the disclosure may provide advantages over prior synthesis techniques by reducing synthesis time. Additionally, methods and systems disclosed herein may achieve better incorporation of nitrogen atoms into the oxide structure due in part to the higher homogeneity of flame made particles and ability to control the reaction environment.
