标题:新型牙本质粘合剂丙烯酰胺膦酸和酯的合成和聚合动力学
摘要:在修复牙科方面,已证明带有膦酸部分的丙烯酰胺单体可用于配制牙科自蚀胶,因为它们可增强与羟磷灰石的粘合力,并且不易水解,因此有可能提高其胶粘剂的耐久性.先前的研究表明,膦酸丙烯酰胺可提高二丙烯酰胺单体的光聚合速率.了解该速率加速是特定于单体的丙烯酰胺功能还是由于膦酸酯基本身,或者仅适用于交联反应,我们合成了几种带有膦酸或膦酸酯部分的丙烯酰胺和甲基丙烯酸酯单体,并研究了它们的光聚合动力学.发现丙烯酰胺膦酸可加速聚合速率,但是带有膦酸酯基团的类似单体的效果要小得多.当膦酸基单体与单官能丙烯酰胺单体共聚时,观测到类似的促进作用,但速率加速可能与交联过程有关.当聚合介质中存在不可聚合的有机膦酸时,也观测到该速率效应.我们建议,介质极性的增加是造成这种速率增强效应的原因.

标题 :Solvents and new method for the synthesis of CdSe semiconductor nanocrystals
发明人：ALKHAWALDEH AMMAR S; PASQUALI MATTEO; WONG MICHAEL S
权利人:William Marsh Rice Universtiy
摘要:New methods for the synthesis of nanocrystals/quantum dots are disclosed. The methods comprise use of reasonably-priced and commercially available heat transfer fluids (such as Dowtherm® A) as solvents to synthesize CdSe nanocrystals. Separation of nucleation and growth is achieved by quenching the reaction solution with relatively cold (room temperature) solvent to lower the solution temperature. Quenching may be followed by raising the solution temperature, to allow controlled growth to take place.

摘要:A method for production of quantum rods is semiconductor luminescent nanoparticles of elongated shape. The semiconductor luminescent nanoparticles are core-shell nanoparticles, where core is CdSe coated with CdS shell. At the current state of the art, mass production of this type of quantum rods is challenging because of extremely fast growth of wurtzite CdSe seeds serving as the core, especially when the seeds size is below 3.0 nm that is required for synthesis of green emitting QRs. We propose the non-injection method for CdSe-seeds which comprises: preparation of single reaction mixture containing both Cd- and Se-precursors, which is liquid at room temperature: pumping the reaction mixture through the heating zone specially designed to provide highly reproducible and well-controllable residential time (0.1-60 seconds) in a heating chamber, thereby resulting in CdSe seeds with low size distribution and narrow emission bandwidth; synthesis of quantum rods using the prepared CdSe seeds.

摘要:A method of making a phosphono-substituted dipyrromethane comprises reacting an aldehyde or acetal having at least one phosphono group substituted thereon with pyrrole to produce a phosphono-substituted dipyrromethane; and wherein the phosphono is selected from the group consisting of dialkyl phosphono, diaryl phosphono, and dialkylaryl phosphono. Additional methods, intermediates and products are also described.

标题:Synthesis of colloidal nanocrystals

摘要:A method of synthesizing colloidal nanocrystals is disclosed using metal oxides or metal salts as a precursor. The metal oxides or metal salts are combined with a ligand and then heated in combination with a coordinating solvent. Upon heating, the metal oxides or salts are converted to stable soluble metal complexes. The metal complexes are formed by cationic species combining with the ligands and/or with the coordinating solvent. Finally, an elemental chalcogenic precursor, for example, Se, Te, or S, is introduced into the soluble metal complex to complete the formation of the nanocrystals at a controllable rate. High-quality CdSe, CdTe, and CdS nanocrystals are produced when CdO is used as the cadmium precursor. With the present method, the size, size distribution, and shape (dots or rods) of the resulting nanocrystals can be controlled during growth. For example, the resulting nanocrystals are nearly monodisperse without any size separation. Further, the method represents a major step towards a green chemistry approach for synthesizing high-quality semiconductor nanocrystals.
