Heat transfer fluids (HTFs) has diversified applications such as chemical processing, concentrated solar power, HVAC system, pharmaceutical processing, plastics processing, system maintenance, and geothermal plant, etc. Enhancing thermophysical properties of HTFs by dispersing nanoparticles on the base fluid which is called nanofluids was first investigated by Choi [1], and nanofluids already have shown heat transfer enhancement [2]. The concept of nanofluids can be applied for other HTFs. Ionic

Ability of cell membrane transport of membrane permeability， diffusion ，osmosis and membrane voltages Introduction Cell membranes are boundaries of the cell, it controls all the interaction between cells as well as passage transport of the material we normally describe as membrane transport. Membrane transport are very essential for all living things, however not all substance can transport in and out of membranes and different ions can pass through membranes in different ways. Membrane permeability

Hydraulic fracturing, commonly referred to as fracking, is a widespread practice in the United States. Fracking is a method used to extract oil and natural gas. Scientists and citizens report detrimental side effects of hydraulic drilling. New York and Vermont have banned fracking statewide. Maryland has set a two year moratorium on fracking, so that more research can be done to show the impacts of fracking on the environment. Nationwide, many other cities and counties have banned fracking as well

Why you should quit smoking and use E-cigarettes Humans have grown on probably the worst habit of all time, smoking either tobacco/any other drug. The amount of people smoking/starting to smoke is rising rapidly each year. Most companies that supply tobacco are trying their hardest to increase their profit and sales, since evolving from ‘the classic pipe’ tobacco is becoming easier to use and easier to get. The price of tobacco/cigarettes are also decreasing rapidly every year which is another reason

This paper is designed for the reader to understand how chemistry is used in Auto Racing. The first main point to be addressed in this paper is Safety and how chemistry is used in the design of race cars and racing safety gear. The second main point to be addressed in this paper is the engine and how the car works. The third main point addressed in this paper is tires. First, Safety is necessary in everything in life, especially in any form of racing especially when you’re reaching speeds up to 200mph

Colligative properties are those properties of solutions that depend on the number of dissolved particles in solution, but not on the identities of the solutes. For example, the freezing point of salt water is lower than that of pure water, due to the presence of the salt dissolved in the water. To a good approximation, it does not matter whether the salt dissolved in water is sodium chloride or potassium nitrate; if the molar amounts of solute are the same and the number of ions are the same, the

Your hair is beautiful and has a number of amazing qualities. It’s versatile; it’s captures attention; it is unique; and, in my opinion, brings out women's beauty and features in ways no other texture quite can! Afro-textured hair can also be quite fragile and prone to dryness. The trick to preventing your hair from damage and breakage is to keep it moisturized. Simply put, if you keep your hair moisturized, your hair will be less likely to snap. One way to achieve moisture is through humectants

6. Oxybenzone Oxybenzone is an ingredient that is found in many sunscreens. The EWG says that Oxybenzone can interfere with your hormones and can even cause cancer. Indeed, it is definitely is a huge hormone disruption. This ingredient acts like estrogen in the body and is linked with endometriosis in women. When absorbed by your skin, it can cause an eczema-like allergic reaction that can spread beyond the exposed area and last long after you're out of the sun. When looking for sunscreens, avoid

previous steps. vi. A graph is plotted with Amount of MB added v/s amount of absorbed MB. vii. At optimum point, the specific surface is computed from amount of MB absorbed. Paper 2: Determination of Surface Area of Fine-Grained Soils by the Ethylene Glycol Monoethyl Ether (EGME) Method. Authors:

polymer is formed while another molecule is released, or "falls out." The condensation polymerization of bis 2-hydroxyethyl terephthalate is carried out in a vacuum at 530 degrees Fahrenheit (275 degrees Celsius) and results in chains of PET and ethylene glycol (see step #1 above); the latter substance is continuously removed during polymerization and used to make more PET. After the PET mixture reaches the required viscosity (thickness), it is cooled to avoid degradation and discoloration. Later, it
