你好，我想问一下你测试的这台仪器哪里有啊？我最近想做粉末的漫反射，一直找不到这个型号的仪器。。
VIS 谱:仪器为 JascoUV560 型。 p~ 计:为 ColeParmer 。 酶活性测定分析: Pl 酶活性分析方法采用 Pl 酶能水解核 糖核酸( RNA )中的磷酸二酯键,生成 5/- 核苷酸,测定溶液中 生成的 5/- 核苷酸在波长 260nm 处的光密度值,便可推算出 酶活力 [ 8 ] 。酶活力的定义:每分钟酶能水解 RNA 所生成的 ...
The out-of-plane quadrupole resonance and transverse localized surface plasmon resonance phenomenon were occurred in UV-Vis spectroscopy analysis of prepared AgNWs samples. A red shift in the peak of the carbonyl bond (–C=O–) in FTIR spectra indicates the interaction of the capping agent with ...
Alumina supported CuCl2, the basic catalyst for ethylene oxychlorination, has been investigated by UV-Vis spectroscopy, EPR, EXAFS and XANES in a wide range (0.25-9.0 wt%) of Cu concentration. We have evidenced that, at low Cu content, the formation of a
UV/Vis absorption spectroscopy clearly demonstrated that the quenching property of TA at λmax = 460 nm was due to overlapping of the fluorescence peak of TA at λmax = 460 nm and the absorption band of CuCl2 (from 190 nm to 525 nm). Binding constant (K′), which was 0.0895 mM−2...
All the fabricated glasses were analyzed by X-ray diffraction patterns, UV-Vis and Raman spectroscopies. In the border of the GFA all the samples presented the crystalline structure of the compound Cd2V2O7, meanwhile inside of the GFA, the samples contain amorphous Cd2V2O7. Into the GFA ...
When dissolved in DMF both compounds form monomeric species [(pydotH 2)CuCl 2(DMF)] which could be characterised in detail by EPR, UV–Vis/NIR spectroscopy and electrochemical measurements. The assignments were supported by comparison with Cu II complexes of the related ligands 2,6-bis(...
UV–vis-NIR Ultraviolet–visible and near-infrared spectroscopy VCM Vinyl chloride monomer XRD X-ray diffraction 1. Introduction The oxidation reaction is one of the most common and significant catalytic processes in the field of heterogeneous catalysis [1], [2]. From the view of fundamental resea...
