of bile and where does it enter the digestive tract? Each group will be assigned one of the following bites of food. First, think about the class of molecule this food item represents and then identify the specific enzymes that would break this polymer into monomers. Remember to describe features that help mechanically digest this bite. Depending on your food item, you may need to do some additional research. Bread Butter Steak Celery…

Introduction/Background -What is the nature of the product or technology? The nature of 3d printing is nearly any area you can think of applying it to. -What is its development history? Rapid prototyping came about in the late 1980s and early 1990s. ‘Rapid prototyping ‘paved the road for all the 3d printing companies out today. (Rapid prototyping created prototypes for a manufacturer to create a prototype of a product with plastics before executing their plans and mass producing them from…

Oxidation occurs when an element loses electrons and reduction occurs when an element gains electrons. Oxidation and Reduction are processes that always work together, hence the term oxidation-reduction reaction or redox reaction. Oxidation is also the gain of oxygen and loss of hydrogen while reduction is the loss of oxygen and gain of hydrogen. Redox reactions occur in everyday life, it is a highly significant form of chemical reaction. Examples of real life redox reactions include: combustion…

present the finding made. INTRODUCTION The packaging industry, Winsome Manufacturing Company, has experience great success for the past 25 years and still counting their years of prosperity. The advancement of an extensive variety of polymers has realized the type of plastic holders…

In an aqueous environment for living organisms, water is used in different ways such as solvents, temperature buffers, metabolite and the living environment. In the solvents, the oxygen atoms of water molecules attracts the cations and by extension the water molecules around it. The more water molecules being attracted the more Hydrogen ions are being formed between them. As a result of this, there is a cluster of water molecules around the ions, therefore the ions are hydrated. Anions also…

Kevlar properties Chemical make-up Kevlar is a weaved fibre known as poly-paraphenylene terephthalamide. Kevlar is part of the aramid family. (Kevlar-The Super Tough Fiber)Aramid chemical name is aromatic polyamide. Aramids was the first organic fibre to reinforce advanced composites. The reason being it strength, and tensile modulus was high enough to be used in advance composites. The fibre mechanical properties of an aramid are higher then most materials like steel and glass fibres if…

benzene ring with two oxygens, each double bonded to it. This product is toxic to bacteria, allowing it to protect the fruit (Why Do Avocados Turn Brown? -The Chemistry of Avocados, 2015). The quinone products react with one another to form long polymer chains, which produces the brown color that appears on avocado after being exposed to oxygen (Why Do Avocados Turn Brown? -The Chemistry of Avocados, 2015). The organic compounds found throughout avocado can play important roles in human…

A different type of Japanese bamboo had been studied by Phong et al. (2012). Moso bamboo was harvested and processed using several methods to obtain the fiber. In alkali extraction method, the bamboo was cut into thin slabs with length and thickness of 25 cm and 3 mm, respectively. The slabs were immersed in different concentration NaOH solution (1%, 2%, 3%) at 70 ⁰C for 10 h. This study showed that only 1% NaOH resulted in higher mechanical properties. The roller looser was then used to produce…

a) Microlens Micolens are small lenses with a diameter smaller than 1 mm, they can work by diffraction, refraction or a combination of these two. When arranged regularly on a single substrate they form a microlens array. In order to be considered a good quality lens, microlenses must have qualities such as to low wavefront aberrations, consistency of focal length and pitch across the array, durability and low price. (Daly 2001) Microlens arrays have several applications, such as CCD arrays,…
