Banana peels were combined with glycerol as a plasticizer and orange peel essential oil that served as an aroma to the plastic. The glycerol makes the edible film flexible and elastic. Banana peels starch were extracted by filtration, banana peels were pulverized and then pressed with a cloth. The essential oil from the orange peel was extracted. White pith from the inside of the orange peel was scraped. Peels were cut into 1-inch pieces and was heated them in 110- to 120-degree-Fahrenheit water…

Findings An artificial Organ is a man-made creation that is implanted within a person in order to sustain/improve a failing organ and can come as a kind of temporary life support while waiting on the transplant list. In some cases, artificial organs can eliminate the need for transplantation altogether however there are many benefits and costs to artificial organs which prevents this. Other artificial organs such as prosthetic limbs and cochlear implants, which are for those in no need of…

Methicillin was first developed in 1959 as an antibiotic against penicillin-resistant Staphylococcus aureus. This beta-lactam antibiotic inhibits the synthesis of bacterial cell walls and inhibits cross-linkage between the linear peptidoglycan polymer chains, essentials for the cell wall of Gram-positive bacteria. This antibiotic is a derivative and modification to the original beta-lactam antibiotic penicillin and is penicillinase-resistant, which is effective against S. aureus bacterium’s…

Synthesis ofp-[1-(p-Hydroxyphenyl)-1-(p-Methoxyphenyl)Ethyl]Phenol (HMEP) 0.2 mol of phenol was mixed with the solution containing 100 mL of acetic acid in 200 mL of concentrated hydrochloric acid in 500 mL five necked round bottom flask fitted with anoil bath, thermometer, mechanical stirrer, reflux condenser. The contents of the flask was stirred for a period of 15 min, the solution was heated to 65oC, 0.1 mol ofp-methoxyacetophenone was introduced into a dropwise to the solution for about 6 h…

Achievement Standard 91604, BIO AS 3.4 • Purpose (why we need glucose and why levels need to be stable) Homeostasis by definition is the maintenance of a stable internal environment despite fluctuations in the external environment. Blood glucose regulation is a type of homeostasis that helps maintain the level of blood sugar in the body and therefore gives energy to cells, making the body able to function properly. It…

perspectives. Non-covalent or covalent functionalization of CNTs can enhance their compatibility and solubility. The non-covalent functionalization of CNTs includes non-covalent coating with surfactants, surface wrapping with long polymer chains, non-covalent adsorption of non-charged polymer chains, etc. the advantage of non-covalent functionalization is that the structure and original properties of CNTs are not changed after modification14. Non-covalent approaches utilize π-stacking or van der…

AC 2.3: Explain the method of making titanium alloy and investigate how the composition and structure of metal alloys, polymers and poly-matrix composites influence the properties of the parent material. 1. Extraction process. 2. Melting process. 3. Storage process. Extraction of Titanium by Kroll process: First titanium ore Rutile (TiO2) is taken. Rutile is converted into titanium sponge by the following process: Titanium tetrachloride (TiCl4) – a colourless compound is obtained as a result…

Question 7 (Viktor): EOQ model The new product line, performance plastics, has to be produced in high volumes. This because the product is 100% the amount that the customer wants. In comparison with the masterbatches, which were only 1% of the volume asked by the customer, this is a significant increase in production capacity. Thus a well defined production planning system is necessary. Nowadays the most important product of performance plastics applies a kanban pull system. This is possible…
