How Do Synthetic Drugs Affect China? Synthetic drugs are prevalent across China‚ affecting the country in countless ways. Drugs are created for medical uses to treat injuries or illnesses‚ however others are exploited due to the body’s reaction towards the drug such as narcotics. A simple definition of synthetic refers to “ manmade” (Van).The primary purpose of synthetic drugs is for medical or pharmaceutical uses. This means that it is intended to aid people who are recovering from ailments. For

the artificial surfaces. Astroturf is a brand of artificial turf or synthetic grass was developed by the Monsanto Industries in the 1960’s. The Ford foundation was studying ways to improve the physical fitness of young people at the time. Monsanto’s Chemstrand division was urged by the Ford foundation to make the perfect sports surface for schools. In 1964 the Creative Products Group installed the first large-scale synthetic turf called Chemgrass at the Moses Brown School in Providence Rhode Island

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

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

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
