starch and test its properties. Potato starch is a polymer made of long chains of glucose units joined together. It actually contains two polymers: q q Amylose‚ which is a straight chain of glucose units Amylopectin‚ which is a branched polymer‚ also made of glucose units. The amylopectin prevents the starch from becoming plastic-like. You will use hydrochloric acid to break down the amylopectin and change the stucture and properties of the polymer. You will make two different batches of the potato

process of interacting with people over wires or through air thrills me and hence I decided to excel in the field of Communications by pursuing Master’s degree from xyz University. I took up Electronics and Telecommunications as my major for an engineering Bachelor’s degree. I was fascinated with not just communications but other fields of Electronics such as VLSI and embedded systems and combined application of these fields result into flawless communication technologies which are existent today

Immobilization of Enzymes And Their Applications By‚ Shudhangshu Shekhar Kundu Introduction: What an enzyme? Enzymes are protein molecules‚ which serve to accelerate the chemical reactions of living cells (often by several orders of magnitude). Without enzymes‚ most biochemical reactions would be too slow to even carry out life processes

Plastics are one of the classification of polymers .If a polymer is shaped into hard and tough utility articles by the application of heat and pressure ‚it is used as “plastic”. Synthetic polymers are often referred to as "plastics"‚ such as the well-known polyethylene and nylon. However‚ most of them can be classified in at least three main categories: thermoplastics‚ thermosets and elastomers. Man-made polymers are used in a bewildering array of applications: food packaging

consideration for their ultimate disposability or recyclability. This has resulted in mounting worldwide concerns over the environmental consequences of such materials when they enter the waste stream after their intended uses‚ Of particular concern are polymers used in single use‚ disposable plastic applications. Plastics are strong‚ light-weight‚ inexpensive‚ easily process able and energy efficient. They have excellent barrier properties. They are disposable‚ and very durable. However‚ it is these

along with other students‚ how to become a world class engineering student. World class engineering students set goals in their academics. They want to graduate with a 3.6 GPA or higher and within four years. From the very beginning they will have a certain degree of engineering set in their mind and stick to it no matter how hard it gets. Currently I have 3.5 GPA before finals‚ but sadly I am behind in math courses so most of my engineering core classes have been pushed back one semester. To reach

An allure for Science and Technology and a keen interest in the growing world of technology led me to take up engineering. I chose to major in Electrical and Electronics Engineering with an intense longing to explore into the challenging field. During my under graduate program I learned the different fundamentals of electrical and electronics which were well-balanced with practical exposure. Right from my school days I had an active interest for science and research. As a matter of fact‚ I used to
