Bibliography EPA. “Carbon Dioxide Capture and Sequestration: Overview.” EPA, Environmental Protection Agency, 6 Jan. 2017. Accessed 30 Mar. 2018. Summary: The article goes over what carbon dioxide capture and sequestration really is, along with why it is beneficial to both our society and the environment. Sequestration is basically storing something, such as the underground storing of carbon dioxide in this case. With the implication of carbon dioxide capture and sequestration worldwide, we may be

global climate patterns. It has correlations to the carbon dioxide levels in the Earth’s atmosphere. Due to the atmospheric carbon dioxide levels, the main effect is on the rise of the average global temperature. The Earth has seen other effects on sea level rise, precipitation changes, and growing season changes. However, climate change has been disputed. This is due to the pockets of slowed climate change, increase in ice gains, and the Earth’s “carbon sinks”. All in all, these findings point to a verifiable

The Development of Carbon Sinks Part 1: Practical Understanding The carbon cycle is the relationship and movement of carbon that among plants, to oceans, to living organisms, and to the atmosphere. Carbon exists in the earth as CO2, and in organisms as sugars or carbohydrates. The carbon cycle works by taking the existing carbon in the atmosphere and taking it in through photosynthesis, animals, oceans, and dead organisms. Animals and humans take in carbon through the plants that they eat and when

gases into atmosphere cause an increase in carbon dioxide concentration by 280 parts per million in 1750 and 390 ppm in 2010 (Kumar et al.2011). Mainly theindustries of plastics, paint, solvents, packaging and cleaning compounds utilizes the carbon. According to Mauna loa observatory in Hawaii, shows the seasonal and annual changes in carbon concentrations since 1958 by keeling curve. This curve shows that the carbon dioxide concentration

seawater. It is caused primarily by the uptake of carbon dioxide in the atmosphere. Oceans were known to balance the components of atmospheric carbon dioxide and mitigate climate change. However, the current rate of intake of carbon dioxide is about 100 times faster than ever before (Oceana, 2012). The rate of absorption is so fast that it alters the chemistry of seawater. Since the beginning of industrial revolution, about one third of the carbon dioxide emitted has been absorbed by the ocean. The

Carbon emissions and GHG present a negative externality towards the global environment, yet these GHG emissions are not easily captured or represented in monetary terms. Several Methods have been used to estimate the value of carbon emissions that might arise from capital protects (Comhar. 2008): Marginal Abatement Cost of Carbon (MAC) or Avoidance Cost, and Social Cost of Carbon (SCC) or Damage Cost techniques. The social cost of carbon has been defined as the full effect on social welfare of

Increases in the amount of carbon dioxide and other greenhouse gases in the Earth's atmosphere have caused an enhanced greenhouse effect. With emissions being produced daily, a large imbalance is being created which is enhancing the greenhouse effect and making it stronger. As there are naturally occurring greenhouse gases in the atmosphere that help keep the Earth warm, additional amounts of these gases leads to more heat being trapped on the planet. This extra heat is causing global warming as

process of removing carbon from the atmosphere and depositing it in a reservoir." This has significant advantages over traditional air-fuel combustion. The mass and volume of the flue gas is reduced, less heat is lost in the flue gas. The size of the flue gas treatment equipment can be reduced. The flue gas is primarily CO2, suitable for sequestration. Because nitrogen from air is not allowed in, nitrogen oxide production is greatly reduced. Keywords: CO2 rich flue gas, Sequestration, Reduced flue gas

flexible. The molecular formula of glycerin is C3H5(OH)3. It is a chain of three carbon atoms, and each carbon atom is bonded to a hydrogen atom and a hydroxyl group. All three carbon atoms have four total bonds. Carbon dioxide is a colorless, odorless gas present in the atmosphere and is formed during respiration. The molecular formula for carbon dioxide is CO2. It has a carbon atom and bonded with two oxygen atoms. Carbon dioxide is only water soluble when the pressure is maintained.

ABSTRACT The Diels-Alder reaction has been an area of great research interest with regards to enhancing enantioselectivity in the reaction by use of various catalysts and reaction conditions. INTRODUCTION In organic chemistry, a Diels-Alder reaction refers to a 4, 2 cycloaddition between a diene consisting of alternating double bonds and a substituted alkene (the dienophile) resulting in a substituted cyclohexene system. The reaction is often used to reliably control regioselective and enantioselective

The huge amounts of plastic thrown away every year are enough to circle the world four times. According to Oxford dictionary plastic is “ a synthetic material made from a wide range of organic polymers that can be formed into shape while soft, and then set into inflexible or slightly flexible form”. It was invented by John Wesley Hayatt in 1869. Today, almost 260 million tons of plastic is produced a year. Plastic does not decompose and it stays on the surface for decades, which led to environment

1. Introduction Friedel–Crafts acylation of aromatic compounds is one of the most important and practical methods to prepare aromatic ketones. The resulting diaryl ketones are important chemical intermediates for the synthesis of a wide range of compounds such as pharmaceuticals, fragrances, flavors, dyes and agrochemicals [1,2]. This is an electrophilic acylation of aromatic compounds with acid chlorides or acid anhydrides, which is traditionally catalyzed by Lewis acids, such as AlCl3, BF3, SbCl5

N‟-2- (bromophenyl)-N,N-dimethylurea 16 underwent lithiation on the nitrogen to form a monolithio intermediate using MeLi, followed by bromine-lithium exchange using t-BuLi to give the dilithio species 17. 14 The intermediate 17 was then exposed to carbon monoxide to give 18, which after cyclization forms the intermediate 19, followed by loss of LiNMe2 to give 20, and finally after work up with dilute acid yielded the isatin product 1. 1 13 14 15 6 N O O 1) MeLi, 0 C CO Br N H O NMe2 2) t-BuLi, 0 C

The solvents used, such as formic acid and acetonitrile, were LC-MS grade and were purchased

IONIC EXCHANGE CHROMATOGRAPHY This is a form of affinity chromatography that allows for the separation of product and contaminants through the use of specific electrical charges produced by the individual molecules. Resins are applied to depending on the compound one wishes to remove ie if your compound is negatively or positively charged. This system is specifically used after one of the three previously stated methods of separation and an ultrafiltration/diafiltrtion step as it is costly and therefore

Introduction 1.1 Aim: To determine the kinetic parameters, Vmax and Km, of the alkaline phosphatase enzyme through the determination of the optimum pH and temperature. 1.2 Theory and Principles (General Background): Enzymes are highly specific protein catalysts that are utilised in chemical reactions in biological systems.1 Enzymes, being catalysts, decrease the activation energy required to convert substrates to products. They do this by attaching to the substrate to form an intermediate; the

Pros and Cons of AI robots Can you imagine your life without technological machines? Technology has played a big part in our life. It is advancing and progressing rapidly in order to increase efficiency. Because of their advanced and useful ability, artificial intelligence, including computerized machines and robots, are spreading worldwide. However, while the uses of robots are helpful and effective, they can cause devastating effects towards people in the world if this technology falls in wrong

Tertiary alkyl halides tend to give a mixture with both inverted and retained configurations at reaction centers. This is because this reaction proceeds through a stable carbocation intermediate and the carbon at the reaction center goes to sp2 hybridized state (planar geometry). The incoming nucleophile can attack from both sides of the plane and can give two products with retained and inverted configuration. If there is a partial interaction with the leaving group (nucleofuge) with carbocation

acid, while the absorption band in 1529.4 cm-1 referred to N-H bending vibration of amine which is possible to be derived from the L-dopa. An intense enough absorption band at absorbance area of 1400.2 cm-1 referred to C-H bending vibration of sp2 carbon, which is possible to be derived from the aromatic ring of amino acid. The weaker absorption band at 1288.4 cm-1 corresponded to =C-O stretching vibration of aromatic compounds, and the absorption band at 1074.3-1118.6 cm-1 referred to C-O stretching

Snowflakes are small and their structure is simple at very low temperatures. At higher temperatures the distinct flakes may be formed from a very large amount of ice crystals - creating a complex star shape and can have a diameter of several inches. (Met Office, 2014) Snowflakes are accretions of several snow crystals. Most snowflakes are less than 1.3 centimetres (0.5 inches) through. Under some conditions, usually needing near-freezing temperatures unstable atmospheric conditions, and light winds
