reaction. 2-naphthol (the reactant) contains two fused benzene rings with an OH group off of a 2o carbon; it’s the presence of the OH group that helps differentiate it from nerolin (the product). This OH group also makes the entire molecule comparatively more polar than nerolin. Nerolin also contains two fused benzene rings, but instead of an OH group it has an ethoxy group (CH3CH2O-) off of a 2o carbon. This makes the entire molecule comparatively less polar and greater in mass and in hydrogen count

ABSTRACT Now -a-days mobile phones have become a fundamental part of our daily life. It is very difficult to see people who doesn’t have smartphone. All smartphones use lithium ion batteries which are rechargeable and capable of holding charge for a short time. This issue can be overcome by using batteries made of graphene which can be charged quickly and hold the charge for comparatively longer time compared to Lithium ion batteries. Super capacitors, unlike batteries can be charged

Eudragit RS and RL 100 polymers have been selected as a carrier for fabrication of nanofibers due to their nice stability, biocompatibility, and nice adhesion over skin due to excellent swelling property, and presence of surface charge. These charges can facilitate prolonged residence time and adhesion over targeted site (Haznedar et al, 2004). Their combination customize drug release, moreover presence of quaternary ammonium compound further check reoccurrence of microbial infection. Chemically

toxic and biocompatible. In terms of shape and internal structure they are largely considered to be quasi-spherical Nano- entities with diameter ranging from 3-30 nm. Their elemental content, C-dots characteristically contains a large amount of carbon (at least 44.50%), along with Hydrogen and Oxygen, in addition to heteroatoms such as Sulphur , Nitrogen, etc might also be present with varying quantity depending upon the synthetic approach and precursors used in their synthesis conditions. As

chemical structure of diamond? carbon atom typically has 6 protons and 6 neutrons in its nucleus, as well as six electrons in surrounding orbitals The electron shell configuration of carbon is 1s2 2s2 2p2. Carbon has a valence shell with four electrons to achieve stability, four electrons must be accepted to fill the 2p orbital Diamond is made up of repeating units of carbon atoms joined to four other carbon atoms by a covalent bond Each carbon atom covalently

Group 1: Gravity Separation Definition of Gravity Separation: Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. Gravity separation uses differences in specific gravity (SG) between various minerals to achieve a separation, and is normally a wet process although examples of dry gravity separators

peak value11 of 20.8 ppm. Comparing with the literature ppm value5 range 5-30 ppm, signal 1 corresponds with CH3-C=O group. This signal was the second to the most upfield and shielded in the 13C NMR spectrum comparing with signal 7 because of the carbon high electron density. However, it was more downfield than signal 7 due to the presence of the oxygen in the group. Signal 2 had an observed peak value of 171.629 ppm and a calculated peak value10 of 171.0 ppm. Comparing with the literature value5

In 1922, at the University of Illinois, William C. Rose began to research amino acids and its relations to metabolism and nutrition. After years of research, Rose discovered Threonine in 1935. Threonine is one out of three proteinogenic amino acids that have an alcohol group. It is one of the twenty amino acids that are common in animal proteins and needed for regular functioning in humans. It is also considered an essential amino acid because the human body cannot synthesize it from other compounds

Preparation of Pyrolysis Oil: Crude pyrolysis liquid was obtained from local suppliers in Phatthalung Province, Thailand, where it was produced as a by-product from the pyrolysis of wood in the process of making charcoal, using rubber wood as a biomass feed. First, the crude pyrolysis liquid was treated to reduce water and remove the fine particles using evaporation and filtration, respectively. The concentrated liquid produced in evaporation was labelled as pyrolysis oil. The oil contained 30wt%

(SO2), hydrogen sulphide (H2S), carbon monoxide (CO) and hazardous polycyclic aromatic hydrocarbons (PAHs) [2-4]. A variety of strategies have been planned as choices to waste tyre managing, all planning at tyre reprocess. Waste tyres can regrettably not be recycled in ‘traditional’ ways such as glass, metal or plastic by thaw out to attain raw material for new products. This is as a consequence of the compound nature of tyres, which consist of steel, rubber, carbon black,ash, fillers, etc. [5]. One
