Bio-diesel is a food- or plant- based similar to ethanol. The disadvantage of bio-diesel is the same as ethanol. It is too costly to produce. Another problem with this is that the food must be turned into fuel rather then eaten. Methanol is a liquefied form of methane. The disadvantage of converting this into fuel is that it is very costly if you compare it to producing gas. The value in using alternate fuel sources is not going to save any money. The addition cost

(also written as NaHO). It is a white solid‚ and is a highly caustic metallic base and alkali salt. It is available in pellets‚ flakes‚ granules‚ and as a 50% saturated solution.[citation needed] Sodium hydroxide is soluble in water‚ ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air. Sodium hydroxide is used in many industries‚ mostly as a strong chemical base in the manufacture of pulp and paper‚ textiles‚ drinking water‚ soaps and detergents

Use of alternate fuels Vehicles must be installed with engines that are fuelled by hydrogen‚ ethanol‚ methanol and natural gas. They are known as cleaner fuels because they release less CO 2 into the air. They are economical as they can be obtained from natural resources.

The objective of present study was to prepare a novel stable Fluorometholone ophthalmic Nanosuspension which has advantage over conventional ophthalmic suspension such as blurred vision‚ burning‚ stinging and irritation upon instillation. The viscosity was increased to provide additional advantage of long duration of action. Precipitation method was used to prepare Fluorometholone ophthalmic Nanosuspension. The type of polymer and stabilizer used showed effect on the particle size and zeta potential

Marijuana is a stimulant‚ that’s currently illegal in the United States. Twenty-eight states have gone through various legislatives to decriminalize marijuana which accounts for 2‚224‚00 people incarnated across the United States [www.Drugpolicy.com].
