ORGANIC LIGHT EMITTING DIODES DONE BY: P.R.SESHADRI ECE-B 3RD YEAR 30410106085 ORGANIC LIGHT EMITTING DIODES INTRODUCTION An OLED (organic light-emitting diode) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound which emits light in response to an electric current. This layer of organic semiconductor is situated between two electrodes. Generally‚ at least one of these electrodes is transparent. OLEDs are used to create digital

Topic: The advantages and disadvantages of organic farming. In spite of organic farming’s unfortunate aspects‚ the number of farmers using this method is increasing due to its advantages. Such method of farming is of considerable benefit in the way that the issue of soil management can be effectively addressed. With organic farming‚ soil quality are maintained and fostered‚ which creates the best opportunity for farmers to take full advantage of soil for years. A further good point of this method

why there are so many obese people in the U.S.? You would think that with all of the buzz about organic foods that we have available‚ that we would slowly be getting better with our weight as a country. Unfortunately the reality of the situation is organic food are expensive and with the way the economy is today many people are working on a budget and simply cannot afford to splurge on the organic items. So now that we know that lets look at the second half of that equation‚ Fast Food! Now as

Nucleophilic Substitution Reactions of Alkyl Halides 1. Summary of Experiment In this experiment we will be comparing the both SN1 and SN2 reactions using various compounds and sodium iodide and silver nitrate. We will be comparing the nature of the leaving group (Cl vs Br) in the 1-halobutanes as well as the effect of the structure

Reminder: These notes are meant to supplement‚ not replace the laboratory manual. SN1 Reaction Notes Background and Application Substitution Nucleophilic First Order (SN1) reactions are one of the most common type of organic reactions. SN1 reactions can be used to make a wide variety of new compounds. In this experiment‚ t-amyl alcohol will be converted by a SN1 mechanism to 2-chloro-2-methylbutane. Safety Precautions Concentrated Hydrochloric Acid is 12M. It will cause visible destruction

I. Abstract The common organic compounds provide us with nutrients are sugars and starches‚ carbohydrates‚ proteins‚ and lipids. In this lab‚ qualitative tests are performed to identify the presence of organic compounds in food using indicators‚ chemical substances that react in a certain way when a particular substance is present. We put one indicator into the each test tube containing different solutions at a time to see what organic compound is present. The color change in the indicator tells

Organic Industry Analysis Managerial Economics Abstract The organic products industry has shown consistent growth over the last 25 years‚ growing 3‚400% (Flynn‚ 2014). The organic industry earned $35 billion in 2014 up from $1 billion in 1990 (Flynn‚ 2014). Credited with being the primary market force drivers‚ food safety and health concerns have been driving the industry since the end of the 2009 recession. This research paper examines the organic products industry and identifies

eating organic foods and the main reasoning for this is because of the way these foods are grown. They are all grown on smaller farms and are cared more for. The farmers use natural soils‚ get rid of the weeds naturally without using sprays‚ and they use beneficially insects and birds to get rid of pests and diseases. Using natural resources to grow foods prevents us from eating chemical and in some cases added hormones. Organic foods have more zinc‚ iron and other vitamins than non-organic foods

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
