Simulation of the Coiling of a polymer strand Tsvetoslav Pavlov Department of Materials‚ Imperial College London‚ United Kingdom 27th Feb 2012 1. Abstract This study will examine the temperature dependence of internal energy‚ heat capacity and R2 value (representative of the end to end distance) using a Langevin Dynamics simulation. It will also consider the dependence of the internal energy‚ heat capacity and R2 value with increasing polymer chain length. Internal energy has been found

performed by Ryan Nelson‚ Peter Glascor‚ Eric Flowr was to determine the identity of the unknown polymer by comparing its properties to properties of other known polymers. Most likely‚ the part is one of the five following polymers: polyethylene‚ polypropylene‚ polystyrene‚ polycarbonate‚ poly(vinyl chloride). These are all extremely common‚ and have widespread applications in industry. Each of these polymers exhibits properties which allow it to be of unique technological importance. Theoretical

Cross Linking effects on Polymers Purpose To observe the properties of the polymers with different amount of borax to see the effects of cross linking. Question How does the amount of a cross linking substances affect physical properties of a polymer Experimental Design A polymer was made with precise measuring of all the reactants especially different measurements of Borax solution as it was the key to cross linking. Physical properties of all the polymers were observed and the role of

Interesting Facts about Pandas Did you know that the panda is the symbol for China? Scientists think that there could be fewer than 1‚000 pandas left in the wild. Did you know that the giant panda is an endangered species? Did you know that scientists take pandas to research stations if the pandas become sick or injured? Pandas are found only in the mountains of China. Panda’s Chinese name is daxiong Mao. It would take 50 Pandas to weigh as much as one elephant. When pandas eat Bamboo their black

Fact Sheet ST-604 October 1994 Strelitzia nicolai White Bird-of-Paradise1 Edward F. Gilman and Dennis G. Watson2 INTRODUCTION White Bird-of-Paradise is most often planted for its large‚ banana-like leaves and upright‚ clumping stalks which give an exotic feel to the landscape (Fig. 1). Plants can reach 20 to 30 feet in height with a spread of 10 feet though they are often seen much smaller. The five to eight-foot-long‚ cold-tender leaves are arranged in a fanlike display from the erect trunks
