investigates an oxidative coupling reaction in an to synthesise triphenylimidazole dimer from 2‚4‚5-triphenyl-1H-imidazole. The resulting compound was investigated for both photochromic and piezochromic properties by way of formation of a stable radical‚ utilizing visual observations and UV-Vis as a means of distinction. Both the oxidative coupling reaction and the dimers interaction with light are depicted in the reactions in figure 1. Figure 1: Oxidative Coupling reaction of 2‚4‚5-triphenyl-1H-imidazol

INTRODUCTION: A high Reynolds number Newtonian liquid jet‚ exiting a two-dimensional channel‚ is examined in this study. Fully developed Poiseuille flow‚ driven by an applied pressure gradient‚ is assumed to prevail upstream of the channel exit. Flow is assumed to be laminar‚ steady and incompressible. A free surface develops as the fluid exits the channel. The resistance of the air on the free surface of the liquid jet can be neglected so that‚ the shear stress at the channel wall disappears and

dabigatran etexilate mesylate (DAB) in bulk and capsule dosage form. A linear relationship was found between fluorescence intensity and DAB concentration in the range of 0.01-1.0 μg/ml in DMSO as solvent at an emission wavelength of 391 nm after excitation at 334 nm‚ with a good correlation coefficient (0.989). The detection and quantification limits were found to be 0.005 and 0.015 µg/ml‚ respectively. The proposed method was applied for DAB capsules‚ results reveal with percentage recovery of 102%

A lot of people who fall in love with a certain person cannot explain why this has happened to them when they are being asked. This is because romantic love has a very mysterious nature which cannot be easily explained and in this essay we are going to examine‚ as far as research allows us‚ some of those factors. Romantic love could be best explained as an emotion that guides a person to be attracted to another. Falling in love is an expression of loving somebody madly. Lamm and Wiesmann (1997) claimed

EC1403 MICROWAVE ENGINEERING UNIT-1 - BASIC MICROWAVE COMPONENTS INTRODUCTION TO F MICROWAVE ENGINEERING Modern electromagnetic theory was formulated in 1873 by James Clerk Maxwell solely from mathematical considerations. Maxwell’s formulation was cast in its modern form by Oliver Heaviside‚ during the period 1885 to 1887.Heinrich Hertz‚ a German professor of physics understood the theory published by Maxwell‚ carried out a set of experiments during 1887-1891 that completely

Arene Molybdenum lab Introduction: Organometallic chemistry is the study of chemical compounds that contain carbon atoms bound to a metal atom. Organometallic compounds can contain main group elements‚ or more metallic elements such as zinc or carbon. These compounds tend to have carbon atoms bound to the metal center by σ-bonds. Alternatively‚ transition metals can be involved in the compound‚ which leads to a variety of interesting and diverse chemical characteristics. For example‚ a promising
