Ethylene glycol

Ethylene Glycol is sometimes used on aircraft de-icing in some parts of the world because it has a lower operational use temperature than the more common Propylene Glycol. Propylene Glycol is more common because it is classified as non-toxic, unlike Ethylene Glycol. Even though it is classified non-toxic it still must be used with a containment system to capture the used liquid, so

solution that is 9.48% Ca(NO3)2 by mass 6. Suppose we make a solution by mixing water and ethylene glycol (C2H6O2, the main ingredient in antifreeze). a. Calculate the vapor pressure of water above a solution made by combining 90.0 g of water and 90.0 g of ethylene glycol at 383.15 K. The vapor pressure of pure water can be found in Appendix B. b. What mass of ethylene glycol would we have to add to 1.00 L of water in order to reduce its vapor pressure to 32.0 mmHg at

According to the American Lung Association (2016), There are approximately 600 ingredients inside on a cigarette. When burned, they make more than 7,000 chemicals. At least 69 of these chemicals are known to cause cancer, and many are toxic. Here are a few of the chemicals found inside a cigarette and other places they are found: Acetone –found in nail polish remover, Acetic Acid – an ingredient use for hair dye, Ammonia – a ordinary household cleaner, Arsenic – used for rat poisoning, Benzene –

NANOFLUIDS Shreya Ghosh Abstract: Nanofluids are nanometer sized engineered colloidal suspension of nanoparticles in base fluids. These fluids have unique transport properties and do not settle under gravity. These fluids have tremendous application in the field of heat transfer, extraction process, industrial cooling and microscale fluid applications. Pioneering nanofluids research in ANL has inspired many intellectual minds to unravel the tremendous potential of these fluids. Little is known about

to achieve the optimum balance of performance and economy in your particular system. However, you may be able to narrow your range of options with a few basic decisions. First, choose a synthetic organic fluid, a silicone fluid or an inhibited glycol-based fluid based on your temperature requirements. If your heat transfer application has a maximum use temperature requirement above 175˚C (350˚F), consider a synthetic organic or silicone fluid. For temperatures lower than 175˚C (350˚F), or

CHAPTER THREE FLOW ASSURANCE MANAGEMENT STRATEGIES As stated earlier in the introductory part of this work, Flow assurance challenges are indeed a great concern to the oil and gas industry. Starting from the formation, through processing and sales, flow assurance management strategies has to be carefully designed in order to prevent having problems with fluid flow. Remediation of hydrates or wax in flowlines and pipelines poses greater challenge and loss of money to the oil industry. This is because

Abstract Surface modification for rapid endothelialization of vascular biomaterials is known as an important way to prevent thrombosis and intimal hyperplasia. Moreover, therapeutical manipulation of microRNAs (miRNAs) expression via local delivery of miRNA mimics or inhibitors by electrospun ultrafine fibers has demonstrated the promise in tissue regeneration. In this work, a dual-functional electrospun membrane was developed by combining Arg-Glu-Asp-Val (REDV) peptide-modification of the fiber

Why you should quit smoking and use E-cigarettes The worst habit that humans have grown on is smoking, smoking either tobacco/any other drug. Each year the amount of people smoking is rising rapidly. The cause of this is the fact that most companies that supply tobacco are trying their hardest to increase their profit and sales, resulting in tobacco becoming easier to use (evolving from the classic ‘Pipe’) and easier to get. The price of tobacco/cigarettes are also dropping every year which is another

Air Force Materials Report: JP-8 and Aviation Fuels The United States Air Force exists to provide a service to the rest of the world. It’s a global service that extends out from the United States and touches every continent around the world. It has been used to bomb evil off of the face of the Earth, drop care to those in need, and transport the strongest fighting forces in existence around the globe. It is airpower. However, as refueling airmen like to say, “Without us, pilots are pedestrians.”

Introduction The objectives in this laboratory were to be able to calculate the freezing point depression among three trials of unknowns, be able to correctly measure the freezing points of p-xylene, and to be able to calculate the molar masses of the unknowns by found freezing point depression values. This was done to be able to understand and apply a concept names supercooling. Supercooling is when a liquid is put far under its original freezing point and remains a liquid or gas. This happens
