- Do you want to know how the things you study are applied in the real world? Let's explore.
Hydrogen for Diesel Fuel Production
Diesel fuel is obtained through refining of petroleum and that needs hydrogen. Refineries use hydrogen to reduce the amount of sulfur in diesel fuel. As the demand for diesel fuel is increasing, so is the need for hydrogen in refineries.
The New Sustainable Energy Technology
Hydrogen is being explored as the transportation fuel of the future. Research is in full swing on how it can be used to run electric vehicles using fuel cells. Fuel cells produce electricity by combining hydrogen atoms with oxygen atoms to produce water. If the technology is successfully developed, hydrogen can be a highly efficient fuel with low emissions.
Hydrogen In Welding
Atomic hydrogen welding is used for welding stainless steel and some special alloys. It produces the third hottest flame, after dicyanoacetylene and cyanogen. It can also be used for almost all the ferrous as well as non-ferrous metals. It is an arc welding process that uses an arc between two tungsten electrodes in a shielding atmosphere of hydrogen. Hydrogen gas is normally diatomic (). At high temperatures, over near the arc, the hydrogen breaks down into its atomic form. After than, when it strikes the object to be welded, which is a relatively cold surface, it recombines into its diatomic form and releases high amounts of energy that enable the welding to occur.
Bleaching Hair with Hydrogen Peroxide
Hydrogen peroxide-based dyes are used to bleach hair. The dyes contain 6 to 10% hydrogen peroxide. These dyes are used to turn dark hair a lighter color before adding another color of dye. It can turn dark brown hair red. Hydrogen peroxide acts by opening the cuticles of the hair so that the bleaching agent can go inside the hair to oxidise melanin that is responsible for colour.
Hydrogen peroxide is also used as an antiseptic, cleaning agent in household and a disinfectant.
Heavy Water in Tracer Studies
or heavy water is used as a tracer to study the different metabolic processes inside living beings. For example, it is used to study the mechanism of respiration and photosynthesis. It can be taken up by cells in the body as normal water, but it can be detected using nuclear magnetic resonance and spectrophotometry. That's how it enables us to study changes in cells of living organisms over time as a result of different metabolic processes.
