Ivacaftor, C24H28N203, is a 4-oxoquinoline-3-carboxamide molecule which consists of five main functional groups: a quinolone, an amide, a phenol, and two tert-butyls. Quinolones are regularly found in anti-biotics, amides are seen in the synthesis of nylon, phenol can be retrieved from coal tar, and tert-butyl groups are big hydrophobic groups found in tert-butyl alcohol (the simplest tertiary alcohol); none of these functional groups were invented or developed first by the parent company of the…

In this modern world, plastic be the most used material for packaging in almost every industry. The word ‘plastic’ comes from the Greek plastikos which means easily shaped (Robertson, 2013). Plastic is the combination of many molecules that linked together as one long chain which made from polymers: poly (Greek) means many and meros (Greek) means part (Robertson, 2013). Raw materials of plastic are called feedstock which come from natural and synthetic resources, such as crude oil, natural gas,…

It is also flexible. This material is also tough. A bumper made entirely of carbon fibre is the lightest available 5.0.0 ADVANTAGES AND DISADVANTAGES OF EACH BUMPER MATERIALS 5.0.1 Steel ADVANTAGES 1. Can have an attractive finish and wide range of decorative finishes available 2. Steel has the highest melting point so less likely…

known industrial processes produce materials which have dimensions in the nanometre size range. One example is the synthesis of carbon black by flame pyrolysis which produces a powdered form of carbon with a very high surface to mass ratio. This is usually highly agglomerated but has a primary particle size which can be of the order of 100 nm. Worldwide production of carbon black was approximately 6 million tonnes in 1993 (IARC,1996). Other common materials produced by flame pyrolysis or similar…

Introduction Graphene is considered as pure carbon in the form of a very thin, one atom thick nearly transparent sheet. It is very strong for its low weight (100 times more stronger than steel and it conducts heat and electricity efficiently. While scientists had theorized about graphene for decades, it was first produced in the lab in 2003. Because it is virtually two-dimensional, it interacts oddly with light and with other materials. Researchers have identified the, ballistic transport of…

Results and Discussion Synthesis of Tin(IV) Porphyrin-Viologen Dyad: Tin(IV)porphyrin-viologen dyads 1 & 2 (scheme 1) used in this study was synthesized by a series of reactions. 1-(4-Carboxybenzyl)-1'-methyl-4,4'-bipyridinium hexaflurophosphate was prepared from the reaction between 1-Methyl-4,4'-bipyridinium iodide with 4-(bromomethyl)benzoic acid followed by ion exchange with NH4PF6. Reaction of 1-(4-Carboxybenzyl)-1'-methyl-4,4'-bipyridinium hexaflurophosphate with [Sn(OH)2TPP] (TPP =…

Asbestos has played a pivotal role in the construction, electrical and automotive industries for many decades due to its excellent thermal and abrasive properties (Brandt 2008). The term asbestos comes from ancient Greek word meaning "inextinguishable". According to Hart (1988), the use of asbestos dates back to prehistoric times where asbestos fibers were woven into a fabric and used as wicks in oil lamps. Asbestos is a naturally occurring mineral which is mined from the earth’s crust. It…

Because of the static configuration is a stable one, in the absence of streaming, the density of the upper fluid be lighter than the density of the lower one. The basic unperturbed flows have uniform velocities and . The two fluids are dielectrics and having the uniform dielectric constants and . The two fluids are influenced by an oblique electric field at the interface between the two media, according to: (2.1) where…
