Latex being collected from atapped rubber tree Rubber tree plantation of Thailand （7 August 2011） Natural rubber‚ also called India rubber or caoutchouc‚ as initially produced‚ consists of suitable polymers of the organic compound isoprene‚ with minor impurities of other organic compounds plus water. Forms of polyisoprene that are useful as natural rubbers are classified aselastomers. Currently‚ rubber is harvested mainly in the form of the latex from

Rubber Band Powered Vehicle Part A: Introduction a. Theoretical Background The rubber band car is a car powered by a single rubber band. Energy efficiency is the amount of energy that is first stored in an object. The physic’s definition of energy efficiency is very similar. Their term is the linear distance traveled using the energy stored in one rubber band. Energy efficiency is usually found when an object’s energy transfers into a different type of energy. For us to find this‚ we have to

Carbopol 940 could yield clear gel with desired rheological property. Carbopol 940 was selected as a gelling agent based on preliminary experiments and previous reports due to its widespread use in pharmaceutical formulations and fast dispersion in water (Sahoo et al.‚ 2014; Sharma and Bedi‚ 2014; Pillai et al.‚ 2015). Moreover‚ it is speculated that Carbopol with low concentration can be safe for nasal administration (Khan et al.‚ 2010). Carbopol is known to have mucoadhesive properties. It

This is more complicated than protein where only 20 amino acids can form a long single chain. Here there can be numerous kinds of bonding forming a straight chain or long chain polymer. More over the number of repeating units are also much greater than giving the structure variation. Carbohydrates can be broken down into

The Earth’s atmosphere has changed over billions of years‚ but for the past 200 million years it has been much as it is today. We are‚ however‚ causing our atmosphere to change by human activity. Burning fossil fuels and deforestation are two examples of human effect on the environment. Composition of the Earth’s atmosphere The composition of air You need to know the proportions of the main gases in the atmosphere. The Earth’s atmosphere has remained much the same for the past 200 million years
