Distillation of Alcohol Beverages Abstract Distillation is a process wherein a liquid is heated until its boiling point while the resultant hot vapors are subsequently captured and cooled‚ and the condensed vapors are collected. Among the many types of distillations‚ the fractional method or technique of distillation was used in this experiment. A step by step procedure was followed and an amount of 3.33 % of ethanol was obtained from the sample wine‚ Mateus Rose‚ which was used. Further

Heavy metal contamination occurs though all facets of life such as air‚ water‚ food‚ soil‚ and in everyday objects and occurrences. When heavy metals enter the air from factories emissions and smoke‚ it is exposed to the body‚ which mostly affect your skin and lungs such as Cadmium and Arsenic. Common water contaminates are Chromium and Thallium‚ Chromium can enter the water source usually through spills and leaks from power plants. Thallium like other metals occurs naturally in water but some areas

of carbon nanotube and carbon nanotube is actually cylindrical form of graphene sheet. The most amazing fact about graphene is it a semi-metal because of having overlap of two bands‚ although it is different from other semi-metals like- arsenic‚ antimony‚ and bismuth . I have achieved A+ grade in my thesis and not only in the thesis but also I got good grade in all semiconductor related subjects in my undergraduate level. I have decent command on MathLab programming language. Nowadays research programs

are hitting landfills each year‚ with the numbers compounding every year. Much of this e-waste contains significant quantities of non-biodegradable toxic substances. Computers‚ servers‚ and other IT hardware contain mercury‚ lead‚ barium‚ arsenic‚ antimony‚ and cadmium. Flat-panel light displays contain mercury and CRT monitors contain lead. When e-waste finds its way into landfills such toxic metals seep out and contaminate the soil and water‚ causing health problems and polluting the atmosphere
