Electrical Science‚Civil‚Chemical‚Mechanical and Automobile Engineering Seminar Projects with Project Ideas for the year 2010‚2011‚2012‚2013 Paper Battery Search This Blog Search A paper battery is a battery engineered to use a paper-thin sheet of cellulose (which is the major constituent of regular paper‚ among other things) infused with aligned carbon nanotubes. The nanotubes act as electrodes; allowing the storage devices to conduct electricity. The battery‚ which functions as both a lithium-ion

Artificial sponges are made in different shapes and in different materials to better fit specific uses of the user. Cellulose sponges are seen a lot in kitchens‚ and can be used in multiple ways. This is the generic sponge that is easy and cheap to make. A newer form of the sponge is the Melamine sponge. This sponge is specialized with a cleaning foam that can absorb water

strong biofilm with very good growth and attachment‚ that when poured out onto a petri dish retains its structure as a single flexible piece. Physically cohesive biofilms also show evidence of cellulose along with other EPS substances‚ showing that for a PC biofilm to form it must consist of a cellulose producing miscroorganism‚ of which the wrinkly spreader is. (Spiers et al. 2009). The above table was compiled after several different groups carried out the experiment‚ taking an observation of

and secondary cell wall. 4. What are the most abundance components of the CELL WALL? And what are the three types? Also list their functions. The most abundant component of the cell wall is Polysaccharide. The three are: Cellulose‚ Hemicellulose and Pectin. Cellulose has crystalline aggregates that give the cell wall its resistance; hemicellulose provides structure‚ regulation and storage to the cell wall and pectin is used as a gel agent. 5. What is the function of protein and approx. how

Describe the substrate and the subunit product of amylase. The following questions refer to Activity 2: Assessing Cellulose Digestion. 5. Does amylase use cellulose as a substrate? Explain. 6. Did freezing have an effect on the activity of amylase? Explain. 7. Do you think that the bacterial suspension contained the enzyme cellulase (an enzyme that digests cellulose)? Why or why not? 8. What is the substrate of peptidase? Explain‚ based upon your results. Protein Digestion by

small structural differences lead to large differences in chemical properties starch found in mushrooms (amylopectin) is a polymer of α-glucose – can easily be digested STARCH = DIGESTIBLE Cellulose found in celery is a polymer of β-glucose – cannot be easily digested by most animals CELLULOSE – NOT DIGESTIBLE • Isomers illustrate that structure of a molecule determines the function of that molecule STRUCTURE = FUNCTION The Molecule of life • Most molecules of living organisms are
Premium Carbohydrate Glucose Disaccharide
Glucose‚ fructose and galactose are MONOSACCHARIDE (SIMPLE SUGAR) 3. The compounds above in #2 have the same chemical formula but differ in ARRANGEMENT OF THE ATOMS. IDENTICAL MOLECULAR FORMULA BUT DIFFERENT STRUCTURAL FORMULA. 4. Starch and cellulose are examples of SUGARS 5. Sucrose‚ maltose‚ and lactose are of DISACCHARIDES (DOUBLE-SUGARS) 6. Chemical reactions that link two or more small molecules to form larger molecules with repeating structural units POLYMERIZATION REACTION 7. Chemical

CHAPTER 1 The Problem and Its background 1.1 INTRODUCTION The growing interest in the past to produce green materials that can reduce the problem involving waste materials by non-fibrous materials led to the development of natural fiber reinforced thermoplastic composites. Water Hyacinth (Eichhornia crassipes) also known as “water lily” is an aquatic plant which is found floating freely in the surface of fresh waters. Its rate of proliferation under certain circumstances is extremely

sugar. Corn contains starch that can relatively easily be converted into sugar. Even most trees and grasses have cellulose that can easily be turned into sugar and then used in the making of ethanol. The ethanol process starts by grinding up the feedstock so it is more easily and quickly processed. Once ground up‚ the sugar is either dissolved out of the material or the starch or cellulose is converted into sugar. Then the sugar is fed to microbes and used for food‚ producing ethanol and carbon dioxide

monosaccharides is a disaccharide. Only monosaccharides and disaccharides make up simple sugars such as glucose and lactose (American Diabetes Association). Polysaccharides‚ or many monosaccharides bonded‚ create more complex compounds like starches‚ cellulose‚ and chitin (McKinley Health
