non-Faradaic reactions. Ion transport and capacitive storage are categorized as non-Faradaic reaction which is standard process that hopefully happen in CDI process, while Faradaic reaction (i.e, redox reactions both on the surface of and within the carbon electrodes) may lead to the formation of chemical byproducts and/or pH fluctuations of the produced water [44], [45]. Faradaic reaction also could lead to instability of long cycle CDI performance, which is specifically caused by reduction reaction

ecological varients that have different carbon dioxide incorporation mechanism have evolved during evolution that are C3, C4 and CAM plants. There is no net carbon dioxide assimilation until carbon dioxide during respiration is fully compensated by photosynthetic carbon dioxide fixation. The supply of carbon dioxide to the chloroplast occurs through diffusion process. C3 Plants: In these plants, first carbon dioxide fixation product is phosphoglycerate a three carbon compound. During light reaction, light

PALLADIUM-CATALYZED CROSS COUPLING REACTION IN ORGANIC SYNTHESIS The formation of new carbon-carbon bonds is of central importance in organic chemistry and a prerequisite for all life on earth. Through the assembly of carbon atoms into chains, complex molecules, e.g. molecules of life, can be created. The importance of the synthesis of carbon-carbon bonds is reflected by the fact that Nobel Prizes in Chemistry have been given to this area many times: the Grignard reaction (1912), the Diels-Alder

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

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
