ALCIAN BLUE RATIONALE FOR USE Alcian blue is a water soluble‚ amphoteric copper phthalocyanine‚ which is most often used as a basic dye. In general‚ alcian blue has an affinity for sulfated and carboxylated groups of acid mucopolysaccharides‚ but the specific group demonstrated is dependent on the dye solution pH. RECOMMENDED FIXATIVES 10% neutral buffered formalin and Bouin’s fixative. AVOID Chromate Fixatives MODE OF ACTION (1‚ 2‚ 3) Alcian blue binds electrostatically with

Linear alkylbenzene (LAB) is the most common raw material in the manufacture of biodegradable household detergents. LAB is produced using normal paraffins as a raw material. Normal paraffins are derived from straight run kerosene. UOP offers processes‚ catalysts‚ adsorbents and equipment for the production of LAB from kerosene or normal paraffins. The processes can be utilized in combination in a new complex or retrofitted or revamped into existing complexes. The UOP LAB complex consists of

melanin biosynthesis‚ with DA oxidized to dopamine quinone‚ then further oxidized to DHI‚ which undergoes deprotonation and cross-linking via Michael addition to form PDA. A solution was prepared to synthesize PDA by mixing 90 mL of water‚ 40 mL of ethanol‚ and 3 mL of ammonia solution in a 300 mL beaker. After stirring for 30 minutes at 37°C‚ a solution of 500 mg of DA dissolved in 10 mL of water was added dropwise using a pipette while stirring at 400 rpm. The reaction was continued for 24 hours at

The following materials: 500 mL used cooking oil‚ 1 kg paraffin wax‚ strings cut into 5 inches long‚ serves as‚ wick‚ crayons in different colors‚ kettle‚ beaker‚ stirring rod‚ mold made from bamboo‚ the researcher conducted the experiment. The measured paraffin waxes will be cut into small pieces to facilitate melting. It will be placed in a clean and dry kettle‚ together with a small piece of colored crayon

Calculations/Analysis Through this lab‚ we are now able to calculate the molar heat of combustion for paraffin‚ since we have the difference of the mass in candle before/after and the periodic table of elements (for converting g to moles of paraffin). Molar heat of combustion = (kJ of heat)/(mole of fuel) However‚ we do not know how much heat was released nor the mole of fuel (paraffin). In order to find the amount of heat released‚ we use the formula: g=mcΔT. Here‚ g represents the heat‚ m

Investigation the effect of the organic solvents on the cell membrane of the beetroot Objective: To investigate the effect of different organic solvents‚ such as alcohol and paraffin oil‚ on the cell membrane of the beetroot by using the red pigments in the beetroot as indicator. Hypothesis: Organic solvents dissolve the organic matter in the cell membrane (such as phospholipids). This destroys the cell membrane‚ and the permeability of the cell membrane is disrupted casing red pigments to

candle and high EC concentrations when the flame was burning unsteady. In the mid 1800s there were two major developments in the candle wax industry‚ stearin wax and paraffin wax. Stearin wax was developed from stearic acid extracted from the fatty acids of animals. This type of candle wax became popular in Europe. Paraffin wax‚ which became popular in the United States‚ was developed as a result of removing the natural waxy substance formed during the process of refining petroleum‚ or crude

Hypothesis It is feasible to make candles out of used cooking. Candles out of used cooking oil can be comparable to candles out of paraffin wax (commercial candle) in terms of: a. Lifespan b. Type of flame Scope and Limitations Upon conducting the experimentation process‚ the researchers had found out some limitations within the projects and these are the following: 1. The researchers did not include the measurement of the amount of light given off by each candle because the instrument used
