...------------------------------------------------- Gas chromatography Gas chromatography (GC), is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture (the relative amounts of such components can also be determined). In some situations, GC may help in identifying a compound. In preparative chromatography, GC can be used to prepare pure compounds from a mixture.[1][2] In gas chromatography, the mobile phase (or "moving phase") is a carrier gas, usually an inert gas such as helium or an unreactive gas such as nitrogen. The stationary phase is a microscopic layer of liquid or polymer on an inert solidsupport, inside a piece of glass or metal tubing called a column (a homage to the fractionating column used in distillation). The instrument used to perform gas chromatography is called a gas chromatograph (or "aerograph", "gas separator"). The gaseous compounds being analyzed interact with the walls of the column, which is coated with a stationary phase. This causes each compound to elute at a different time, known as the retention time of the compound. The comparison of retention times is what gives GC its analytical usefulness. Gas chromatography is in principle similar to column chromatography (as well as other forms of chromatography, such as HPLC, TLC), but has...

Characterisation and Degradation of ABA Tri-Block with Disrupted Ends BEng (2012) ------------------------------------------------------------------------------------------------------------------------------------------------ NANYANG TECHNOLOGICAL UNIVERSITY CHARACTERISATION AND DEGRADATION OF ABA TRI-BLOCK WITH DISRUPTED ENDS Submitted in Partial Fulfillment of the Requirements for the Degree of Bachelor of Engineering of the Nanyang Technological University By Foo Yong Quan School of Materials Science and Engineering 2012 ABSTRACT Four tri-block copolymers composed of poly(L-lactide)-poly(caprolactone-co-L-lactide)-poly(L-Lactide) (PLLA-PCLLA-PLLA), with disrupted ends were characterised according to individual’s mechanical and thermal properties. The tri-block copolymers consist of amorphous PCLLA middle block, at constant composition of CL and LLA being 60% and 40% respectively. The end blocks consist of either a semi-crystalline PLLA or various compositions of P(LLA-DLLA). Factors such as high overall crystallinity and effective crosslinking of arms led to the high modulus values of polymers...

...CHAPTER 1 INTRODUCTION 1.1 General The micro-emulsion inks have a wide range of applications in industry. The ink used earlier for printing purposes contributes to pollution in environment. The pollution is by means of emission of volatile organic compounds (VOCs) which are present in the form of an aliphatic solvent. Emission of VOCs from these solvents and their discharge in waste streams are quantifiable. For example a typical medium size cold – set web plant uses 40,000 kg per year of the ink of which 6000 kg is lost as emissions. The plant uses over 10,000 kg per year of cleaning solutions all of which is lost in atmosphere. A typical newspaper uses 100,000 kg per year of ink and emits over 8000 kg of volatile solvents (Maji, 2003). VOC when released into the atmosphere participates in the atmospheric photochemical reactions. Ozone is produced at the ground level when oxides of nitrogen and VOCs react in the presence of sunlight. This is a major component of urban smog, which at elevated levels causes a potential hazard to humans, plants and animals. To overcome the problems of emissions due to solvent-based inks and cleaning of presses, a new type of ink based on vegetable oil has been developed which is biodegradable and environment-friendly. It does not contain aliphatic solvents, and hence its use produces virtually no emissions during printing. Also, this ink contains vegetable oil (castor-oil)-based alkyd resins, which are biodegradable and generate no...

...possible without any warming of tissues which impose of the current radiation exposure levels. KEYWORDS Mobile Radiation, Health Effects INTRODUCTION There are now about 1 Billion mobile phones in use worldwide, and it is expected to reach 1.6B lines by year 2005. In many countries, penetration rates of more than %50 has been reached. At present, there are approximately 4.5 million GSM subscribers in Saudi Arabia and STC has commissioned Ericsson and Nokia to expand its GSM network to 5.5 million lines (~ %20 penetration rate). This wide use of mobile technology have often raise the question about if there are health implications for human. In fact, there are conflicting reports relating to possible health effects from mobile phones and base stations. In April 2000, an independent expert group in UK has issued a report on Mobile phone effects on health based on rigorous assessment of research in this area and show no evidence of the impact of mobile phones to human health. Since then a number of studies has been accomplished. This paper summarizes previous results. Then, the current...

ABSTRACT Recycling aluminium now is fairly popular in the world since more than 15% of the aluminium would be machined down to have the final product. However, melting these Al rubbish to make the ingots is energy consuming and not environmentally friendly. Therefore, the way of using powder metallurgy to make use of these scraps could be an economic way of recycling since it doesn't need to be fully melted. The objective of the project is to use Al6063 scraps to produce porous...
