Polymerization

Bandyopadhyay, 2011). Nanoscale building blocks are individually exceptionally strong because they are close to ideal, defect-free materials. There are three methods to prepare nanocomposites, they are: solution casting, melt blending and in-situ polymerization. Polymer nanocomposites for various applications could be synthesized by proper selection of matrix, nanoreinforcement, synthesis method and surface modification of polymers. (Paul & Robeson,…

Characterization of the oxidized amylose and the linalool/oxidized amylose inclusion complex. The high water solubility of oxidized amylose can broaden the applications in water environment.14, 32 The Table 1 shows the properties of amylose and oxidized amylose. As expected, the solubility of oxidized amyloses in water is highly improved due to the introduced carboxyl and carbonyl groups. And it increases greatly with the increase of carboxyl content. The results suggest that due to the two-step…

How Does Hydroxyurea Work To Treat Sickle Cell Anemia? Problem: Suffering From Sickle Cell Anemia. Sickle cell anaemia is a severe hereditary form of anaemia. Anemia is a condition where there is an inadequate amount of red blood cells or haemoglobin in the blood. HBB also known as haemoglobin beta or Beta globin is 146 amino acids long that makes up most of the haemoglobin in adult humans. HBB protein is produced by the gene HBB that is located in the multigene locus of β-globin locus on…

Division of pre-existing cells is the only way through which new cells can come into being. For duplication of cells to happen, the genetic materials inside the cells have to duplicate first. During the S phase of the cell cycle, the chromosomes of the cells as well as the chromatin proteins duplicate. During the M phase, spindle fibers are formed, and the duplicated chromosomes arrange themselves in the equatorial region of the cells forming a metaphase plate. Mitotic spindles are formed by the…

Bouncy balls are made up of Polymers, which are made up of many small units of monomers, that go through the process of Polymerization to become Polymers. People can see such polymers all around them like rubber, wool, silk etc. Polymers have unique properties that allow chemist’s and scientists to mix different types of polymers with each other to form new ones. In the lab Polyvinyl Acetate (PVAc), Polyvinyl Alcohol (PVA), and Sodium Borate were used to make and design the bouncy balls. The…

The concrete is the second most used product world-wide after water. The construction industry is one of the vital sectors in the nation’s economy. The concrete mainly contains ordinary Portland cement as a primary binder and production of ordinary Portland cement causes 7% of the total greenhouse gases in to the earth’s atmosphere (Malhotra 2002) and production of the ordinary Portland cement produces carbon-di-oxide in mainly two ways , they are burning of fossil fuels and the other is…

The focus of my case analysis is J.R., a 53 year old Hispanic male who has retired after serving 23 years in the United States Army. His hobbies include playing golf and watching sports. J.R has health insurance through Tricare and he is able to receive medications at no cost when his prescriptions are filled on the military base at which he sees his primary care provider. He is allergic to shellfish and the reactions that he experiences are hives and airway swelling. He currently smokes 1 pack…

INTRODUCTION Cancer can be defined as a special kind of illness that occurs when the cells in a given part of a body begin to grow out of proportion than is normal. Currently, in the United States, this disease is the second leading cause of deaths. Human beings over the history have had tumors and remedies have been implemented, and others continue to be performed and studied over time (American Cancer Society, 2010). These methods of treatment include chemo-preventive methods and of late…

1 INTRODUCTION Drosophila Melanogaster, also known as the fruit fly, is a most valuable organism in biological research that has made significant contributions particularly in genetics and research. It is used as a model organism in research for several reasons viz. Easily handled, sexually dimorphic, cheap and easy to keep large numbers, care and culture requires little equipments and well understood because of its short life cycle of just two weeks and also Entire genome of drosophila…

Ebola virus disease (EVD) causes major illness in humans, which leads to death; this virus is the most lethal virus that has infected primates. The appeared originally in areas of Sudan and Zaire in the year of 1976. It is believed that the natural reservoir of the virus comes from fruit bats. Ebola is part of the Filoviridae family. The virus is mostly transmitted through direct contact with bodily fluids such as saliva and blood. Ebola can be difficult to detect in the beginning due to its…
