    Introduction Bio-based polymers are materials which are produced from renewable resources. The terms bio-based and biodegradable will be used repeatedly in the literature, however there is a key difference between the two types of materials. Biodegradable are defined as materials whose physical and chemical attributes will undergo degradation and completely deteriorate when exposed to microorganisms, aerobic processes, anaerobic processes, or both process simultaneously. On the other hand, Bio-based

    NANOFLUIDS Shreya Ghosh Abstract: Nanofluids are nanometer sized engineered colloidal suspension of nanoparticles in base fluids. These fluids have unique transport properties and do not settle under gravity. These fluids have tremendous application in the field of heat transfer, extraction process, industrial cooling and microscale fluid applications. Pioneering nanofluids research in ANL has inspired many intellectual minds to unravel the tremendous potential of these fluids. Little is known about

    The polymer that I choose is polyethylene glycol (PEG). Polyethylene glycol is produced because of the interaction with ethylene oxide with water, ethylene glycol or ethylene glycol oligomers. Some cons of using polyethylene glycol are hypersensitivity, unexpected change in pharmacokinetic behavior, and toxic side products. PEG is also a laxative that can also be used to prepare the bowels before surgery. PEG is also used to slow the clearing of protein from the blood. This makes medicine last longer

    1. Explain, in detail, the meaning of the following statement. “Pasteurization is not sterilization” These two method of microbial control are used for different purpose, while sterilization is used to keep instruments, equipment, materials and objects free from harmful microorganisms, viruses and bacterial endospores, pasteurization is used keep food and beverages from spoiling by killing pathogens and reducing the number of spoilage microorganism. During the pasteurization of food products, not

    solution that is 9.48% Ca(NO3)2 by mass 6. Suppose we make a solution by mixing water and ethylene glycol (C2H6O2, the main ingredient in antifreeze). a. Calculate the vapor pressure of water above a solution made by combining 90.0 g of water and 90.0 g of ethylene glycol at 383.15 K. The vapor pressure of pure water can be found in Appendix B. b. What mass of ethylene glycol would we have to add to 1.00 L of water in order to reduce its vapor pressure to 32.0 mmHg

    A submerged plants will have a hyponastic response caused by a buildup of the compound ethylene (Visser et al., 1996). Ethylene is found in higher concentrations in submerged plants when compared to non-submerged plants and has been shown to enhance the growth of the petiole during water logging (Monaco & Cumbo, 1972). In flooded conditions petiole elongation

    C2��C3 single bond is expected to form a methyl-substitute lanthanacyclopropene [La(CH==CCH3)] + ethylene, whereas a 4,2-H migration followed by the C2��C3 bond cracking should produce lanthanacyclopropene [La(CH==CH)] + propene. Competing with the 1,3-H migration, a H atom in the methyl group could also migrate to C3 to form La[H2CC(CH2)CH2CH2] which then may decompose to La(CH2==C==CH2) + ethylene or La(CH2CH2) + allene through the cleavage of the C2��C3 single bond. We report here the MATI spectroscopy

    Other publications deem Sodium Laureth Sulfates (SLES) as the more ‘toxic’ chemical of the two. It is believed that SLES can be contaminated when in contact with a 1,4 dioxane (1,4-Diethyleneoxide), which is a by-product of an ethylene oxide. The chronic exposure of an ethylene oxide has been related to the occurrence of cancer. These sulfates are used to obtain the foaming effect that most shampoos, skin cleansers and other cosmetic products produce. These sulfates are also used in detergents

    Assignment 3 Q1: how does the industry work? Polyethylene is a petrochemical product that has been widely used in the plastic manufacturing, such as packaging, trash bins, and food containers. It is produced mainly from the polymerization process of ethylene, which is an ingredient derived from cracking crude oil and natural gas. There are three types of polyethylene: low-density polyethylene (LDPE); high density polyethylene (HDPE); and low linear density polyethylene (LLDPE), and each of them has distinctive
