Stuff Matters is a book by Mark Miodownik where he explores the different origins and properties of materials that are in our daily lives. The materials around us are taken for granted, thus not many people can answer the question of why the materials look, feel, and act the way they do. A prime example is plastic. Polymers, or plastics, are considered one of the six classes of materials that has changed the world. Plastic is held with high status in the material world because of its extensive…

This means each gram of PLGA microsphere is loaded with 381 mg of risperidone (2). The clear and colourless diluent contains the surfactant polysorbate 20 to reduce the surface tension for easier reconstituting, the stabiliser sodium carboxymethyl cellulose to stabilise the micro suspension, sodium chloride and sodium hydroxide to adjust the pH, disodium hydrogen phosphate dihydrate, citric acid anhydrous and water for injections…

After being lifted from the plate and placed in the mouth, the poor pizza goes on a long journey through the digestive system and eventually is turned into waste after passing through the 6 primary organs of the digestive tract: the mouth, oesophagus, stomach, small intestine, large intestine and anus. The process of digestion starts when Bob the pizza is placed in the mouth. The main structures of the mouth are the teeth, tongue, salivary duct and oesophagus. Bob is killed, being chewed on by…

MYCOCEPT (Mycophenolate mofetil) is the 2-morholinoethyl ester of mycophenolic acid (MPA). CHEMICAL NAME: 2-morpholin-4-ylethyl (E)-6- (4-hydroxy-6-methoxy-7-methyl-3-oxo-1H-2-benzofuran-5-yl)-4-methylhex-4 enoate. STRUCTURAL FORMULA: Fig: Mycophenolate mofetil MOLECULAR WEIGHT: 433.50g/mol APPEARANCE: Mycophenolate mofetil, is a white to off-white crystalline powder. SOLUBILITY: It is slightly…

The experiments were carried out in triplicate at initial concentrations of 25, 50 and 75 g-COD L-1. Additionally, to test the inoculum quality, positive controls with 25 g L-1 of cellulose instead of POME samples were also included for observation. When the hydrogen production ceased, the serum bottles were opened and another 150 grams of anaerobic digestion sludge was introduced into the reactors and incubated at 37°C for 45 days…

Part C Question 1 Addition polymerization In addition polymerization, polymer is formed by addition monomer without eliminating any product at specified temperature, pressure and presence of catalyst. Different methods of addition polymerization are free radical polymerization, cationic polymerization, anionic polymerization and coordination polymerization. Mainly addition polymerization occurs in the monomers having double bound. This process has three stages initiation, propagation,…

discuss the economic importance of fungi let us have a brief study about what fungi really are. Fungi are multicellular, eukaryotic, non-chlorophyllous, living organisms which feed heterotrophically by absorption and have a cell wall made up of fungal cellulose and have a body made up of hyphae called mycelium. In this universe each and everything has its own economic advantages and disadvantages. Let us first study the advantages of fungi. ADVANTAGES OF FUNGI ROLE OF FUNGI…

riboflavin as well as the consumption rate of the vitamin in media, when analyzed at different activation times. The decrease in riboflavin over time makes sense as the bacteria and archaea in the media use the vitamin as a cofactor in the digestion of cellulose as well as with other sugars and fats. (2) The The LOD and LOQ of the acetic acid solution were well below the concentration standards used for riboflavin, though the LOQ was close to the riboflavin values when the media was run on its…

Neil Mann, who is a Professor & Head of Food Science & Nutrition in RMIT University, spoke about evolution and our dietary change, specifically the difference on our nutrition today and the time of our hunter-gatherer ancestors. There is a huge contrast in terms of energy density of foods and other key food compositional differences, which has led us to have disease today. He stated that we are not so healthy in these 50-60 years according to our diet intake. Food is our main energy sources. We…

were made by machines instead of by hand. Because of the increase in production, there was a need for packaging methods. At first, food packaging was primarily made from paper based materials or glass jars and jugs. It wasn’t until the 1950’s when cellulose plastic was introduced that plastic packaging gradually became more common. There are many functions of food packaging such as protection, containment, marketing and convenience. In spite of the convenience, there are negative impacts of food…
