Title: Thin-Layer Chromatography Objectives: Part1: 1. To learn the technique of TLC and the visualization of colourless components. 2. To identify an unknown drug by a TLC comparison with standard compounds. Part 2: To learn the separation technique by using Thin Layer Chromatography plate in separating a mixture of compounds into individual pure compound by using Spinach Leaf. Introduction: (i) General Concepts Chromatography is a common and powerful method used to separate and analyze complex

In this study‚ glass spheres coated by TiO2 nanoparticles and N-Doped TiO2 nanoparticles for photocatalytic applications on the treatment of methylene blue and olive oil waste water. Synthesis of TiO2 and N-Doped TiO2 nanoparticles performed by sol-gel method. The effects of residence time‚ number of coating‚ initial concentration of waste water and initial volume of waste water have been invastegated. Increasing number of coating resulted in a increasing percentage of degradation. The effects of

company decided to proceed with the project‚ then the new product‚ Energy Gel‚ should be evaluated. The Energy Gel case describes three approaches in order to estimate project costs which are direct cost advocated by Harry Wickler‚ full cost supported by Mark Leiter‚ and equipment based costing supported by Frank Nanzen. The direct costing basis only considers the variable costs that are directly identified with the Energy Gel project. However‚ it ignores many costs or benefits including cannibalization

have to be adopted to utilize them for the conversion into value-added products [Nand‚ (1998)]. Pectin exists in varying amounts in fruit cell walls and has important nutritional and technological properties‚ mainly because of its ability to form gels (Westerlund etal‚ 1991). Pectin is a polysaccharide having properties such as gelation and emulsion stabilization which make it useful in the manufacture of food‚ cosmetics‚ and medicine. It is a normal constituent of food and may therefore be safely

forensic anthropologists ran a gel electrophoresis with DNA from Skeleton 3 and two missing persons‚ Julia Ly and Teresa Chen to help in DNA identification. This process would allow restriction enzymes to cut by a specific restriction site and run through the gel‚ where the DNA fragments would move from the negative side to the positive side of the gel due to the negative charge of the phosphate group in DNA. The smaller the DNA fragments‚ the further they move down the gel. As mentioned above‚ the DNA

2.6 Kinetic studies of prepared complexes The integral method of Coats–Redfern equation[19‚21‚27‚38] was used for determining the kinetic parameters of the decompositions process for the investigated metal complexes according to following equation: log[log(w_∞/(w_∞-w))⁄T^2 ]〖=log[AR/〖∅E〗^* (1-2RT⁄E^≠ )]〗-E^≠/2.303R 1/T (4) Where w_∞ is the mass loss at the accomplishment of the decomposition reaction‚ w is the mass loss at temperature T‚ ∅ is the rate of heating and R is

INTRODUCTION To begin the process of protein extraction and compare the results in a study‚ it is necessary to understand the importance of proteins‚ the process of extraction and how you are using the results to determine a rational conclusion. First understand proteins and the necessity of studying their impact. Proteins are essential molecules for biological functions and are the

The Isolation‚ purification and identification of Proteins assayed From Bovine Liver Using SDS Gel Electrophoresis‚ Mass Spectroscopy and Western Blotting Abstract The purpose of the experiment was to isolate and recognize varying protein solubilization and assaying methods by using bovine liver protein. The experiment implicated the impact of different types of solvents like ethanol‚ water‚ PBS‚ PBS+1% Triton x-100‚ and PBS+2% SDS on protein solubilization. Bradford and Ghosh/Dumbroff

aesthetic plays an very important role‚ more hairstyling products emerge. They can be categorized under hair wax‚ hair mousse‚ pomade‚ hair gel‚ hair spray‚ hair volumizer‚ and miscellaneous. Hair wax is a thick hairstyling product containing wax‚ and it is basically used to assist with holding of the hair. However‚ it does not harden like products such as hair gel‚ but remains pliable. This properties of hair wax give the more natural look for hair. An example of a brand is Gatsby. Hair mousse
