AIR PURIFIERS (OZONIER AND PECO)

Today there are lot of air purifier depending upon different principles. Most of the purifiers depend upon tradional method 'HEPA'. But now technology is changing and also purifiers that now even purifies air at micro level. Two of the principles on which these purifiers work are 'PECO' and 'Ozonier'.

HEPA


This is now a tradional method to purify air. HEPA stands for high-efficiency particulate air. A HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke. You can find HEPA filters in most air purifiers.

OZONIER

Used to purify air

It is a type of air purifier that uses ozone to kill bacteria. Ozone is a naturally occuring gas. A molecule of ozone has three oxygen atm. Ozone layer shields Earth from the harmful ultraviolet rays of the sun, it is pollutant at ground level.
However when used in right amount, ozone can purifies the air.

An ozonier is a device that generate ozone by charging the air with high voltage electricity. The gas is then released in air. Ozone improves air quality by removing unpleasant odours and killing microbes.

This is also used to sanitize food and drinking water without hurting their nutritional content.

On the flip side, some scientific studies suggest ozone can be harmful for humans and hence it should be used in care.

 PECO


Today the new, best and safe concept of air purify is PECO. Photo Electrochemical Oxidation (PECO), works at the molecular level to eliminate indoor air pollution.

Developed over two decades by research scientists, PECO is an innovative technology that utilizes free radicals—the same radicals used to kill cancer cells—to oxidize pollutants.

By using nanotechnology, PECO is able to destroy pollutants 1000 times smaller than traditional HEPA filters (0.1 nanometers versus 300 nanometers). With the help of this engineers made a purifier known as MOLEKULE


STEP1. Air Intake
It intake air from every corner
STEP2. Pre Filter
The air is circulated through the pre filter, trapping larger allergens like dust, pollen and dander.
STEP3. Nano Filter
PECO at work. A chemical reaction is created when a nanoparticle-coated filter is activated by light, breaking down harmful pollutant to their most basic molecular components.
STEP4. Pure Air
Molekule disperses harmless molecules that are meant to be in air, leaving your home pollution free in minutes.


The standard on the basis purifiers are tested is CADR


CADR stands for Clean Air Delivery Rate. This lets you identify how quickly the air purifier functions. It calculates how many cubic feet of air the purifier can filter in one minute. Higher the CADR number, better the air filtration. Air purifiers consist of three CADR numbers for dust, pollen and smoke.

What is Nebula. Images of some nebula by Hubble

A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries." How do stars form in a nebula? Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star. Some of the most amazing nebula pictured by Hubble in Milky Way Galaxy The Eagle Nebula’s Pillars of Creation (M 16, Messier 16) The dust and gas in the pi

STARS GOING OUT OF CONTROL

Stars Gone Haywire. As nuclear fusion engines, most stars live placid lives for hundreds of millions to billions of years. But near the end of their lives they can turn into crazy whirligigs, puffing off shells and jets of hot gas. Thanks to Hubble which give us a chance to view these beautiful stars. The Butterfly Nebula Imagine a lawn sprinkler spinning wildly, tossing out two S-shaped streams. At first it appears chaotic, but if you stare for a while, you can trace its patterns. The same S-shape is present in the Butterfly Nebula, except in this case it is not water in the air, but gas blown out at high speed by a star. The S-shape directly traces the most recent ejections from the central region, since the collisions within the nebula are particularly violent in these specific regions of NGC 6302. "This iron emission is a sensitive tracer of energetic collisions between slower winds and fast winds from the stars. It's commonly observed in supernova remnants and active gala

WHAT IS A BLACK HOLE

In April, NASA created a big announcement that they captured first image of black hole.  BUT WHAT IS A BLACK HOLE It is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. The result is a gravitational field so strong that nothing, not even light, can escape. Most famously, black holes were predicted by Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core. If the core's mass is more than about three times the mass of the Sun, the equations showed, the force of gravity overwhelms all other forces and produces a black hole. HOW THEY ARE FORMED Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.) If the total mass of the star is large e
