kilowatt-hour battery, and the Chevrolet Volts having a $500-$930 per kilowatt hour battery (National Bureau of Economic Research, 2012). To increase energy efficiency, hybrid and electric vehicle bodies are also being increasingly constructed from polymers, aluminum, or composite body panels. Lithium-air batteries have a higher energy density than a conventional lithium-ion battery, meaning it has five to ten times more energy than regular lithium-ion batteries (National Bureau of Economic…

In chemistry, theta is a temperature where a polymer solution behaves ideally to its osmotic pressure. Iota: Iota is the ninth letter of the Greek alphabet (I, ι) , and it describes the ninth brightest star in a sequence. Iota also means a small quantity. Kappa:Kappa is the tenth letter of the Greek…

One of nature’s finest peculiarities is the mantis shrimp, a crustacean closely related to the pistol shrimp. The pistol shrimp occupy the family Alphidae, while mantis shrimp are the most notable part of the broader order Stomatopoda (Duffy, 2003). Nonetheless, the groups are considered evolutionary brothers and the traits and instincts of the organisms are closely related, as both have the strength and agility to create cavitation bubbles as a direct result of their strike (Patek, 2004). In…

Now barefoot does have many pros to it, and I want to make sure I acknowledge them. If your horse is kept barefoot you will definitely save a large chunk of money over time. We pay $85 for re-shoeing a fully shod horse. We pay this amount every 7 weeks when our farrier comes out. That means we pay an average of $630 per year, per fully shod horse. A barefoot trim usually costs right around $20 dollars. Barefoot horses need to be trimmed every 5 weeks, the cost averages right around $210 per year…

What comes to your mind when you hear the word cosmetics? It certainly isn’t in your everyday discussion, but still; does makeup come to mind? Or hair and skin care? Maybe nothing comes to mind at all. However, cosmetics are everywhere! Cosmetics include products we socialize in our everyday routines allowing us to maintain our hygiene and keep our skin and hair properly moisturized for a picture perfect appearance. But why not get deeper? Who are the masterminds behind these divine creations?…

1.4.2.2 Oxidizer The oxidizer is an another basic ingredient of solid propellant which produces high energy during combustion of composite solid propellants, which can be referred to as the substance that whose function is the oxidizing materials or supply of oxygen for deflagration of a propellant. Ammonium perchlorate (AP) is the most commonly used oxidizer in solid propellant applications, which replaced Potassium Perchlorate in the late 1940’s. AP was used as an oxidizer in various types of…

SPRAY FOAM BASEMENT INSULATION: TORONTO Introduction Spray Foam Insulation (SFI,) also known as Polyurethane foam, is a very common practice among homeowners in the United States, UK, Canada, Australia, and some other countries. SFI is a heat-induced polymer – a spray-applied plastic with specially designed equipments capable of forming continuous insulation and serving as sealing barrier on walls, round corners, roofs, floor or ceiling cavity, as the case may be. It is produced by the mixture…

Staphylococcus aureus is responsible for various types of infections including skin and also respiratory tract infections. S.aureus can infect tissue when if the defensive line such as the skin or mucosal barriers had been breached. The infection caused by this bacteria can be spread in different modes such as direct contact from an infected wound, contact with the hyaluronidase, an enzyme produced by the bacteria that destroys tissues or even skin to skin contact with an infected person.…

every living organism. These four molecules consist of simple sugars, fatty acids, amino acids, and nucleotides. "Poly-" means "many", and "saccharide" means "sugar," so as the name suggests, a polysaccharide is a type of sugar. In fact, it is a polymer made up of chains of sugar monomers, also known as monosaccharides, and monosaccharides are simple sugars such as glucose, fructose, and galactose. Sugars are important because they make up carbohydrates…

When I was in Haiti, I remember sitting in class thinking about how much I love biology and chemistry. Coming back from school, I always told my parents and my little brothers what I learned in those classes. When I came to this country three years ago, my interest in the scientific field grew more. I finally thought deeply about what I wanted to do with my life and decided to major in chemistry. I became so interested that even when I was bored, I went through my chemistry book just to read and…
