affixed to the fiber‚ so that it may not be affected by washing and friction. Textile printing is a process through which a pattern‚ color‚ or combination thereof is applied to the surface of a textile. When a fabric is dyed‚ all the fibers absorb the dye and assume the designated color. With textile printing‚ however‚ only the surface fibers or specified area of the textile receives the color or pattern. As a result‚ the color is not applied uniformly but in selected regions. As a method of printing

LABORATORY EXERCISE 8-A: Preparation of Bacterial Smear and Simple Staining I. INTRODUCTION Bacterial smears are prepared for the purpose of viewing microorganisms under the microscope. Visualization of microorganisms in the living state is very difficult‚ not just because they are minute‚ but because they are transparent and almost colorless when suspended in an aqueous medium. A bacterial smear is a dried preparation of bacterial cells on a glass slide. Smears may be made from a dry culture

lightstick. There need to be two chemicals that interact to release energy and also a fluorescent dye to accept this energy and convert it into light. Although there is more than one recipe for a lightstick‚ a common commercial lightstick uses a solution of hydrogen peroxide that is kept separate from a solution of a phenyl oxalate ester together with a fluorescent dye. The color of the fluorescent dye is what determines the resulting color of the lightstick when the chemical solutions are mixed. The

Candy Chromatography: What makes those colors? The point of doing this project is to use paper chromatography to see which dyes are used in the coatings of your favorite colored candies. Chromatography is a technique for separating mixtures. Chromatography can be used to separate specific components from a complex mixture‚ based on molecular size or other chemical properties. It can also be used to identify chemicals‚ for example crime scene samples like blood‚ drugs‚ or explosive residue. Highly

Although‚ bacteria are defined and visible noted. Most of the time they are single round cells. In direct stain with crystal violet‚ again background is colorless and glossy. Bacteria is blue and some uneven grouping is noted. In this example the dye methylene blue stain is used. In indirect stain with Congo red stain‚ background is again colorless and glossy. Bacteria are orange to red and fine defined. At smaller magnified example they are grouping in uneven clusters‚ but in highest magnifier

polymer used for a wide variety of commercial applications‚ and a vast majority of this polymer is synthesized via free-radical polymerization. The polymerization of styrene is often initiated by thermal generation of radical species. For example‚ azo-bis-isobutyronitrile (AIBN) thermally decomposes to form 2-cyano-2-propyl radicals that initiate the polymerization of styrene to polystyrene (Scheme 1). Scheme 1. AIBN decomposes into 2-cyano-2-propyl radicals 2-cyano-2-propyl radicals react

A Brief Introduction to Sulfasalazine Sulfasalazine is a sulfa drug derived from mesalazine (5-aminosalicylic acid known as 5-ASA). Often prescribed as an effective medication against inflammation-related symptoms‚ it has multifaceted effects towards several diseases including intestinal diseases as well as rheumatoid arthritis.1 Sulfasalazine has been widely used for decades since its approval by FDA.2 Apart from the common uses‚ researchers also recently discovered that sulfasalazine could potentially
