INNOVATIVE DISCOVERIES IN 21st CENTURY

1. Hydrogen cars

Hydrogen cars function with the help of batteries that use hydrogen as fuel. These batteries are called `Fuel Cell’ that is different from the normal batteries used in common engines. Because these normal batteries work due to the reaction of chemical substances in them. In fuel cells, gases like hydrogen and oxygen react with each other to form heat energy, and water and the engine will be highly performable until it gets enough oxygen and hydrogen. As these cars with hydrogen batteries do not use petroleum as fuel, it doesn’t cause environmental pollution.

2. Scramjet

Rockets that can spring at a greater speed than sound waves are called `Supersonic Rockets’. Supersonic combusting ramjet widely known as ` Scramjet’ is the newer model of ramjet. Ordinary jet engines are performed by the combustion of the mixture formed by fuel and air. Hence these elements should be amassed in engines whereas ramjet only needs fuel as it absorbs air while combusting fuel and runs through this process. As the absorption of air is at supersonic speed, the speed will also be higher. It was Russia, that firstly manufactured scramjet and in 1991 NASA also produced it. The speed of air is 1,235 km per hour in which ramjet thrusts with a minimum of 3,675 km per hour.

3. Nano-textiles

Can you imagine a cloth material that can’t get wet by water, can’t get dirty, and also with disease resistance? Incredibly, nanotech fabrics that were designed during the advent of nanotechnology in 1980 are capable of these features. These fabrics are with less than 1000 nanometers density and with elastic nature. These can be manufactured by sewing nanofibers or smearing ordinary cloth materials with fluid-containing nanoparticles. Nanotech fabrics are with `Superhydrophobicity’ as it never allows water to enter also its odorless nature prevents moisture and thus resists bacterial growth. They can be used in the medication of diseases by placing these nano clothes upon the infected or diseased areas. The clothes are with many holes and gaps in which the required medicine is filled and thus it penetrates the body parts.

4. XStat

XStat is an instrument manufactured by some doctors, researchers, engineers of RevMedx company in 2014. This was designed to save the wounded soldiers forbidding high blood flow from the wound. XStat is a syringe filled with sponge capsules and as injecting medicine in the syringe into the body, sponge capsules are being injected into the body through these XStat. They rapidly expand and rises pressure and thus forbids blood flow. Also, the medicine in it helps for fast healing.

This is how our world thrives as E-World from the modern world by the 21st century.
