CHAPTER 2 LITERATURE REVIEW 2.1 Effect of Binder and Plasticizers on the Gel Viscosity, Membrane Morphology and Pore Size According to M.R. Othman [7] the result of addition of PVA in Boehmite sol during peptization on the viscosity, coating time, pore size and BET surface area is presented in Table I,II,III, and IV. PVA was prepared by dissolving 2, 4, 6 and 8g of PVA powder into 100mL de-ionized distilled water. PVA with different concentration in the sol give a of characteristics viscosity…

present in prokaryotes and usually chemically complex. If a cell wall is present in eukaryotes then it is usually chemically simple. In bacteria the cell wall is made up of peptidoglycan, while in eukaryotic plant cells it is usually made up of cellulose. Cellulose is chemically simpler than…

Stachybotrys (black mold) is a dark green almost black slimy mold that produces a deadly poison called mycotoxins. It often grows on cellulose based items like straw and paper after coming into contact with water. Stachybotrys enters a person’s system through the spores. Spores are tiny seed like structures which are produced in the mold. Mold spores are invisible to an person’s naked eye…

the paper chromatography experiment was the filter paper. The mobile phase used in this experiment to help separate the pigments were the hexane and acetone solution. Boiling the spinach leaves helps to release the pigments by breaking down the cellulose. After adding the spinach leaves and the solution, there was not a lot of extraction collected…

Carbohydrates are the main source of energy for living beings; its consumption is vital to our existence. The Carbohydrates play various roles in our body; the main ones are the nutrition and energy supply. The body will use every trick to keep the fed cells, as the glucose supply cannot stop. Foods rich in carbohydrates, such as breads, cereals, rice and pasta, are an important form of energy for the body and, therefore, are very important to a healthy diet. However, when consumed in excess,…

Ribose and deoxyribose sugars forms the structural frame of the genetic material, RNA and DNA. Polysaccharides like cellulose are the structural elements in the cell walls of bacteria and plants. Carbohydrates are linked to proteins and lipids that play significant roles in cell…

usability of perishable goods, or let consumers know when pharmaceuticals are past their prime. The way out of our landfill dependency could solve more than one problem if people and industry could be convinced of the benefits; Frito-Lay produced a cellulose based chip bag for their popular sun chips but, was ultimately dropped because consumers complained that the bag was too loud; the sound of a waste product should not be the determining factor for a solution to worldwide…

degrading cell wall compounds and extractives. The extractives in the wood degrade more easily, and these compounds evaporate from the wood during the heat treatment. The hemicelluloses are the first structural compounds to be thermally affected. Cellulose and lignin degrade more slowly and at higher temperatures than the hemicelluloses. The change in wood structure and chemical components during heat treatment affected the properties of wood. Hidayat et al. (2014) revealed that heat treatment…

Chitosan is a natural linear amino polysaccharide gained from chitin which is, after cellulose, the second more common biopolymer on earth. Chitin is the primary component in the shells of crustaceans such as shrimp, crab, and lobster. Chitin is present in crayfish, insects, and vegetal species mainly in the walls of fungi. These species require nitrogen for nutritional cycle. Chitin has been sourced from different originate and its composition shown in table 2.1 (synowie). Small quantity of…
