Colloid

Emulsion Independent Research 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 combination of a water, or water like substance and a oil, or lipid based substance together. The mixture is mixed thoroughly, usually by means of mechanical force, like shaking, forming a solution, resulting in a homogenized solution.…

Emulsions are mixtures that contain two or more substances that cannot combine to make homogenous mixtures. One of the liquids contains dispersions of the other substances. The emulsions are formed from shaking the substances vigorously to counteract the different densities of the substances. The extra substances added to the emulsions beside water and oil are refered to as emulsifiers. The emulsifiers are substances added to keep the oil from separating completely from the water. Emulsions are…

One of the most unusual substances in chemistry, slime blurs the line between solid and liquid stages of matter. Slime and other substances like it are common in the average everyday life today, and yet are almost unnoticed. Slime is a colloid, a substance that shares both liquid and solid traits. Many colloids are polymers, which are a certain type of molecule. Although slime may seem simple, in reality it is quite complex in the microscopic standpoint. Slime can also be referred to as a…

infused with crystalloid fluid during surgery. The maintenance of colloid osmotic pressure (COP) and total protein (TP) is necessary to avoid intra- and post-operative complications. Methods: Twenty nine horses being treated for colic underwent surgery. The horses received IV Xylazine before being anaesthetised, followed by a variety of drugs as required. Lactated Ringer’s saline solution was administered throughout surgery and the volume was recorded throughout surgery. Blood…

1.1 Overview: In a research lab, Mr. Z trying to formulate a colloidal dispersion system with sodium lauryl sulphate. What type of colloidal system is suitable for sodium laurly sulphate and also we have to discuss the different stability factors for sodium laurly sulphate dispersion. 1.2 Solution to the question: Introduction of colloids: Colloids are homogeneous non-crystalline substances. Here one substance is divide into more minute particles called colloidal particles and then it…

in to the blood stream. When speaking about Intravenous Cannulation, the introduction of two terms arise , with their own very unique, special and extremely important characteristics. Colloid solutions and Crystalloid solutions.(Case, 2013) Discussion: Crystalloids & Colloids Crystalloid solutions are the most frequently used, with normal saline (NS) and lactated ringers (LR) both being the most often and common choices across the globe. Colloids are the alternative to the previous…

Colloids and Crystalloids on fluid resuscitation during hypovolemic shock John Tristan Pahuyo, Staff Nurse ACCU-Barts Heart Centre Hypovolemia is generally defined as having a significant amount of blood volume loss. Shock, on the other hand, is a medical emergency characterized by inadequate blood flow to organs and tissues thus reducing oxygen delivery that leads to organ dysfunction. Hypovolemic shock is described as a loss of greater than 15% of the intravascular volume. It is caused by an…

action of the heart pumping and the effect of gravity on blood flow creates hydrostatic pressure while osmotic pressure is created and generated by the molecules in the solution (Scales & Pilsworth, 2008). The molecules that generate the osmotic pressure are usually large protein molecules, referred to as colloid molecules, which will be discussed in more detail (McGloin, 2015). Understanding the movement of electrolytes and water within the body is crucial for intravenous fluid…

Colloid solutions are known as volume expanders because it draws the fluid from the interstitial space and into the intravascular compartment. The advantage of utilizing colloid solution is that it holds a slower duration of action and remains inside the intravascular space for longer. Five percent albumin, Low-molecular weight dextran, high-molecular dextran, and hydroxyethyl starches are all colloid solutions. The albumin solution is most commonly used and is able to pull in four times its…

thyroid gland that are each composed of an enclosed sphere of epithelial cells. These cells surround a protein-rich core called the colloid. The follicular epithelial cells contribute to most of the stages of thyroid hormone synthesis and secretion. Iodide molecules are acquired from the diet and are vital for the production of thyroid hormone. Iodide trapping is the first step in synthesis. This occurs due to circulating iodide cotransporting with sodium ions across the basolateral membranes…
