标题:Tandem Photocatalytic Oxidation Of Rhodamine B Over Surface Fluorinated Bismuth Vanadate Crystals
摘要:以 Bi(No3)3 和 V2O5 为前驱体,通过 Naf 介导的水热法合成了具有单斜相和可控形貌的 Bivo4 晶体.作为结构控制剂加入的 Naf 不仅影响了 Bivo4 晶体的演化过程,还使合成的 Bivo4 晶体实现了原位表面氟化.有趣的是,在氟化 Bivo4 光催化剂上,Rhb 的光催化氧化反应以阶梯式的方式发生,即先发生较快的去乙基化过程(rhb 转化为罗丹明),然后发生相对较慢的矿化过程,包括破坏罗丹明中的共轭结构.表面氟化有利于 Rhb 分子和 Bivo4 光催化剂之间的 Rhb 吸附和空穴传输,从而逐步加强最初的直接空穴传输介导的脱乙基过程.与此相反,表面氟化对-O2-介导的矿化过程产生了折衷效应,既增强了表面 Rhb 吸附,又阻碍了电子从 Bivo4 光催化剂转移到 O2,从而产生-O2-,因此需要适度的表面氟覆盖率来平衡上述相互冲突的效应,实现更高的矿化率.本研究不仅证明了光催化效率可以通过调节光生活性物种和光催化反应过程来改变,而且为氟化对半导体光催化的影响提供了新的见解.

标题:Greener Synthesis of Nanoparticles Using Fine Tuned Hydrothermal Routes
发明人：MAYE MATHEW
权利人:MAYE MATHEW; UNIV SYRACUSE
摘要:The synthesis of energy and sensor relevant nanomaterials that involves the colloidal synthesis of quantum dots (e.g. CdSe, CdS, ZnS, CdSe/ZnS) under well-controlled hydrothermal conditions (100-200 degrees C.) using simple inorganic precursors. The resulting nanomaterials are of high quality, and are easily processed depending upon application, and their synthesis is scalable. Scalability is provided by the use of a synthetic microwave reactor, which employs dielectric heating for the rapid and controllable heating.

标题:Methods and devices for detecting printhead misalignment of an in situ polymeric array synthesis device
发明人：LEPROUST ERIC M; AMORESE DOUGLAS A; KRONICK MEL N
权利人:AGILENT TECHNOLOGIES INC
摘要:Methods and devices for detecting deposition unit misalignment, e.g., printhead misalignment, of an in situ polymeric, e.g., a nucleic acid, array synthesis device are provided. In accordance with the subject methods, at least one test probe feature is synthesized on a substrate using an in situ polymeric array, e.g., nucleic acid array or protein array, synthesis device. The at least one test probe feature is then contacted with at least two different distinguishably labeled targets, e.g., target nucleic acids. The binding of the targets to the at least one test probe feature is then evaluated to detect any misalignment, e.g., deposition unit or pulse jet misalignments, of the synthesis device. Also provided are substrates having at least one test probe feature and at least one polymeric array, as well as methods of using the substrates in array assays. Also included are kits for use in practicing the subject methods.

摘要:Provided are methods for labeling transfer RNA comprising replacing the uracil component of a dihydrouridine of said transfer RNA with a fluorophore. The disclosed methods may comprise fluorescent labeling of natural tRNAs (i.e., tRNAs that have been synthesized in a cell, for example, in a bacterium, a yeast cell, or a vertebrate cell) at dihydrouridine (D) positions, or fluorescent labeling of synthetic tRNAs. In another aspect, the present invention provides methods for assessing protein synthesis in a translation system comprise providing a tRNA having a fluorophore substitution for the uracil component of a dihydrouridine in a D loop of the tRNA; introducing the labeled tRNA into the translation system; irradiating the translation system with electromagnetic radiation, thereby generating a fluorescence signal from the fluorophore; detecting the fluorescence signal; and, correlating the fluorescence signal to one or more characteristics of the protein synthesis in the translation system. The disclosed methods are useful in single molecule as well as in ensemble settings.
