Why is organic chemistry important? Organic compounds are used for many different things. Daily life in today’s world would be very hard to live in without organic compounds; in fact life would not be possible without organic compounds. For example‚ most of your body is made up of organic compounds. The food you eat is made up of organic compounds. Even the flavourings and colourings on processed food are organic. The clothes you wear are‚ yes you guessed it‚ organic as well. What’s more is that

SUMMARY AND CONCLUSION 6.1 Summary Silver nanoparticles are nanoparticles of silver composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. Various shapes and sizes of nanoparticles are synthesized by physical‚ chemical and biological methods. The Chrysophyllum canito leaf extracts were used for silver nanoparticles synthesis. In this study utterly revealed the best milli molar concentrations of silver nanoparticles synthesis in diverse solvents such

BIOPOL Biopol is a biopolymer that is an environmentally friendly biodegradable plastic made from renewable resources (made naturally in plants from starch and glucose). Biopol is the brand name for a group of biopolymers often called PHAs or PHBs. The continual use of petroleum to make polymers for plastic will eventually run out and hence Biopol was introduced as a polymer replacement for petroleum. It is made from an organic substance known as Alcaligenes eutrophus which is a microorganism.
