Will Changing the Temperature of the Cream Affect the Mass of the Butter Particles? Purpose: The purpose of the experiment was to see if the temperature of the cream would affect the mass of the dried butter. Background Information: Cream is the part of the milk that rises to the top during milk production. Cream is a liquid at room temperature, but it is very versatile and contains certain characteristics that allows it to change form. (Lower, 2017). Using only a little force, the cream…

fluorescence PET sensor (AMG) was developed for detecting high pH values and water content in organic solvents. A guanidine group as a proton receptor was covalently attached to an anthracene fluorophore to afford highly polar AMG, with reasonable solubility in highly basic solution. The fluorescence of AMG increased almost linearly with decreasing pH in the range 11.0–13.0. AMG also exhibited a fluorescence turn-on response to water in various organic solvents such as 1,4-dioxane, DMF, CH3CN,…

Introduction It is evident throughout the world today that the quality of water has become increasingly important in terms of not only ensuring that every individual has an adequate quality and quantity of the substance, but also for the maintenance and sustainability of the world’s natural environment (. However despite water quality remaining as an essential part of life for all living organisms, the influence of human developments involving farms and urban areas have brought a somewhat…

Symptoms of allergy can be treated with H1 antihistamines. The purpose of treatment is to prevent histamine to stimulate the receptors, why they consist of the same core structure as histamine . These H1 antihistamines constitute the second most commonly used class of medications after antibiotics and there are many varieties used in different conditions . H1 antihistamines are classified into six groups: ethanolamines, ethylene diamines, alkylamines, piperazines, piperadines, and phenothiazines…

Introduction Doxorubicin, an anthracycline antibiotic, is commonly used as an effective antineoplastic agent, in the treatment of various of malignancies, including leukemia, lymphoma, and solid tumors. Unfortunately, the clinical use of this drug is limited by cumulative dose-dependent cardiotoxicity, which may cause irreversible and severe effect of cardiomyopathy [1] The specific mechanisms of doxorubicin (DOX) induced cardiotoxicity are complex and although decades of research on this drug,…

antibacterial,3,4 antiviral,5,6 antiprotozoal,7,8 anti-cancer, 9,10 and anti-hypoglycemic.11,12 However, in many cases the effective concentrations of most of the natural triterpenoids are not low enough for their therapeutic use. In addition, their solubility in water is low, which causes insufficient bioavailability. As a result, it is necessary to focus on the preparation of triterpenoid derivatives with higher activity, improved pharmacological properties, and more favorable therapeutic…

He reacted glycols and dibasic acids with strong acids under a reduced pressure in a molecular still. The results of early polyesters, however, were a problem: they had such a low melting point and a high solubility in solvents that they were not viable. After attempts to solve these problems, Carothers discontinued the research. Elmer Bolton encouraged him to not give up on the wider study of fibers. When Carothers renewed his work in that area in early 1934…

the phospholipids the heads stick out and the tails touch each other staying away from the water. The proteins divide the group of phospholipids from each other. There are three variables that effect moving across the cell membrane. First is the solubility, if it is soluble it can easy move across and if it is not then it will have a harder time moving across. The size effects it as well the bigger the object the harder it will be. The smaller it is will make it easier for it to move across.…

Vitamins was the fourth chapter that I read. Vitamins are organic compounds essential in small amounts for body processes. They enable the body to use the energy provided by carbohydrates, fats, and proteins. Vitamins are commonly grouped according to solubility. Each vitamin has a specific function or functions within the body. The fifth chapter I read was about minerals. Minerals are inorganic elements that are necessary for the body to build tissue, regulate body fluid and assist in Various…

Project A combined effort of Timothy Chase Willard and Marcus Bortey of Mr. Cork’s Second Period chemistry class December sixteenth of 2014  Background Information An emulsion is a mixture of two or more chemicals in liquid form with no mutual solubility. Emulsions are part of two-systems of matter called colloids. Colloids are particles that cannot be seen without the use of a microscope, but are larger than the size of the individual molecules involved in the emulsion. Usually the…
