标 题:Precursor chemistry for quantum dot synthesis enabling temperature-independent modulation of reactivity
发明人：HAN HEE-SUN; PARK JOONHYUCK
权利人:UNIV ILLINOIS
摘要:Provided herein are methods of making a high-quality quantum dot (QD), including by providing anion precursor chemistry that enables chemical modulation of precursor reactivity, thereby, allowing independent optimization of reaction temperature and precursor reactivity to systematically grow high quality QDs and by providing specially configured tunable precursors and related chemistry to facilitate separate reaction pathways for nucleation and growth, thereby accessing heat-up based synthesis of high-quality QD, including core-shell QDs. The methods may include providing a base-QD and a first anion or cation precursor having a composition comprising an anion or a cation element, respectively, and a modification agent. At least one add-layer is grown on the base-QD at a growth temperature, thereby making the high-quality QD comprising the base-QD and the at least one add-layer. At least one add-layer may have a composition comprising an add-layer cation element and an add-layer anion element.

标题:Application of Mannich base in flame-retardant polyurethane material

摘要:Application of a Mannich base in a flame-retardant polyurethane material is provided. The Mannich base has a structure represented by a formula (I). In the Mannich base, flame-retardant groups, i.e., halogens are introduced at the second, fourth and sixth positions of a phenyl group, and flame-retardant elements, i.e., halogens and nitrogen are introduced into synthesized polyether polyol, giving the synthesized polyether polyol good flame retardance. The amount of active hydrogen in the Mannich base is small so that occurrence of side reactions during the synthesis of the polyether polyol is reduced, and the viscosity of the flame-retardant polyether polyol is lowered. Due to autocatalytic performance of tertiary amido in the flame-retardant polyether polyol, use of a catalyst can be reduced and even avoided during the synthesis. A preparation method of the Mannich base is also provided.

发明人：MCALPINE SHELLI R; TAYLOR RACHEL E; BOLLA MEGAN L; SEGALL ANCA M
摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.

标题 :Phase boundary process for the preparation of aromatic polycarbonates using a chlorinated aromatic hydrocarbon as the polymer solvent
发明人：VERNALEKEN HUGO; HUCKS UWE
权利人:BAYER AG
摘要:The present invention provides a process for the preparation of a polycarbonate by the phase boundary condensation method, by phosgenation of an aqueous alkali metal salt solution of one or more aromatic dihydroxy compounds, in which process an aromatic chlorinated hydrocarbon is used as the solvent and the synthesis of the polycarbonate is carried out in two stages, in the first stage of which the reaction of the alkali metal salt solution of the aromatic dihydroxy compound(s) with phosgene is carried out at an OH concentration of between 0.01 and 0.1% by weight of OH, relative to the aqueous phase, in the presence of 0.1 to 2.5 mol% of trialkylamine, relative to aromatic dihydroxy compound(s), and at a temperature higher than 70° C, with a dwell time of less than 5 minutes, while in the second stage the polycondensation is effected by adjusting the OH concentration to 0.20 to 0.50% by weight of OH, relative to the aqueous phase, optionally with further addition of trialkylamine, at a temperature higher than 80° C and with a dwell time of more than 1 minute.
