Design and Fabrication of Pedal Operated Air Compressor
Abstract: The first idea for powering the pump would be a stationary bicycle. Pedal power is simple, efficient, and practical. Its most familiar use is the bicycle for personal or cargo transportation. But pedals can also power small stationary machines. Since the system is to remain human powered and large amounts of power are required, having the operator use their stronger leg muscles was intuitive. A stationary pedal driven device seemed …

Tetrahydro-dibenzo[a,d][7]annulene-5,11-dihydrazone and Magnesium oxide Used to Control the Corrosion of Aluminium in Chloride ions Environment
Abstract: Chloride ions interact with aluminium in marine atmosphere to form corrosion cell. Due to this corrosion reaction occurs on their surface, aluminium is oxidized into Al3+. The corrosion reaction accelerates deterioration in metal and it produces galvanic, pitting, stress, crevice, intergranular corrosion. Chloride ions decrease internal and external strength of aluminium metal. It is a very important metal so used in different appliances for e.g. road, water, air transports, housing, …

Corrosion Protection of Copper Metal by Nanocoating in Nitrogen dioxide Environment
Abstract: Nitrogen dioxide is an acidic gas. It absorbs moisture to produce nitric acid. It creates corrosive medium for copper metal. It forms corrosion cell on the surface of copper and accelerate corrosion reactions. The corrosion cell formation is written as: Cu|Cu2+||H+|H2 thus corrosion reactions start and copper is oxidized into Cu2+surface and it is oxidized into Cu2+ whereas H+ ion is reduced into H2. Nitric acid environment copper exhibits galvanic, …

Chemical Process of Diamonds and CVD Methods
Abstract: Many times, first-order kinetics can be seen in gas-phase decomposition events. However, it is now known that such reactions are actually governed by bimolecular processes. Bimolecular collisional activation to an energy sufficient for decomposition sets off the reaction. Gas-phase processes occurring in catalytic cycles are also to blame for the development of the ozone hole in the polar stratosphere in the spring, albeit heterogeneous mechanisms must also be taken into …
