    INTRODUCTION Conformational isomerism is a type of stereoisomerism whereby the isomers are interconverted by rotations about the single bonds. There be terms used below such as eclipsed conformation, staggered conformation,dihedral angle and a few more. Eclipsed conformation is the conformation whereby the C-H bonds on one carbon is directly aligned with the C-H bonds of the adjacent carbon. When the C-H bond of one carbon bisects the H-C-H bond on the adjacent carbon, it is known as staggered…

    Polarization curve Fuel cell creates 1.16 V of equilibrium potential between hydrogen and oxygen. However, the actual open circuit voltage is around 1 V due to temperature, pressure, and the concentration of the reactant. The ohmic loss is the resistance loss induced by the unique resistances of the component of fuel cell. And the concentration loss occurs when reaction rates of hydrogen and oxygen are faster than their supply rates. (1) The diffusion flux created according to…

    product obtained will be different. Primary alcohols have one carbon and two hydrogen atoms attached will produce aldehyde and then to carboxylic acid in two steps by oxidation. While secondary alcohols have two carbon atoms and one hydrogen atom attached will produce ketone by oxidation (Kotz, et al., 2015) Aldehydes, the compounds that the carbonyl group has a hydrogen atom attached to it together with either a second hydrogen atom or a hydrocarbon group. Ketones are the compounds that two…

    Water is a transparent, odourless, tasteless liquid, a compound of hydrogen and oxygen freezing at 30°F or 0°C and boiling at 212°F or 100°C, that in a more or less impure state constitutes rain, oceans, lakes, rivers etc; it contain 11188% of hydrogen and 88.812% of oxygen by weight. (Dictionary.com) The Earth is surrounded by 70% of water, however, that 70% is composed of salt water and fresh water. The salt water is made up of 97% and fresh water is 3%. 2% of the fresh water is frozen up in…

    NiCd is the chemical abbreviation for the composition of Nickel-Cadmium batteries, which are a type of secondary (rechargeable) batteries. Nickel-Cadmium batteries contain the chemicals Nickel (Ni) and Cadmium (Cd), in various forms and compositions. The nickel-cadmium battery, invented by Waldmar Jungner in 1899, offered several advantages over the then only rechargeable battery, lead acid, but the materials were expensive and the early use was restricted. Developments lagged until 1932 when…

    enter the house and allow the stale air to exit. The effects of VOCs can also be lowered by minimalizing exposure to these compounds. An example of a VOC is methanol, a substance which is toxic if ingested because it metabolises to form Formaldehyde (CH_2 O). Methanol (CH_3 OH) is most commonly found in products such as cigarettes as well as in foods or drinks containing aspartame, an artificial sweetener. Formaldehyde is another toxic VOC which can cause the development of cancer. Formaldehyde…

    Fig 4.12 shows the comparison of product density of hydrotreated GO obtained using CAT-E and CAT-C. The density of hydrotreated GO from CAT-C at 370◦C was 0.8148g/ml whereas at the same temperature the density of hydrotreated GO obtained from CAT-E was 0.8302 g/ml despite sulphur and nitrogen in the GO has been reduced to less than 50 ppm and 1 ppm respectively. The reason for higher density would be due to higher aromatic content in the hydrotreated product obtained from CAT-E. This indicates…

    Characterization of the oxidized amylose and the linalool/oxidized amylose inclusion complex. The high water solubility of oxidized amylose can broaden the applications in water environment.14, 32 The Table 1 shows the properties of amylose and oxidized amylose. As expected, the solubility of oxidized amyloses in water is highly improved due to the introduced carboxyl and carbonyl groups. And it increases greatly with the increase of carboxyl content. The results suggest that due to the two-step…
