Graphene Filter for Air

What is Graphene?
An introduction to the world’s strongest material, graphene.
This is a cute video that explains in simple details what graphene is and what it will be used in for the future. Since it can be layered it will make a great filtration system.

Graphene which is a flat layer of carbon atoms tightly packed into a two-dimensional honeycomb arrangement is so thin it’s almost transparent. So far nothing has been found to replace graphene in out performing  all other materials. There is so much new nano-technology going on with graphene and all that it is capable of doing such as graphene filters. Because of the nano structure graphene filtration systems can work along the traditional filtration systems and filtrate out what the traditional filtration systems can not. Graphene filters are good at catching hydrocarbons. With this nano-technology  nano‐systems which are filtration systems using graphene are being studied to make filtration systems that helps clean the air and water we need to survive. Besides graphene filters being used in water filtration, which at the present time seems to be gaining momentum in research for cleaner water there are other uses for graphene filters. Sheets of graphene have been created to use as a a tunable resonator in a filter that’s very smaller, low powered and simple to be tunable. This device could enable extra versatile wireless circuits that would operate at many various frequencies and also in a position to integrate with current silicon chip technology. Only the the resonant frequency can make the graphene vibrate. With the existing technology we have now tuneability is only about 1 percent, so with the resonant frequency of the suspended graphene,  tunability  electrically has increased by as much as 400 percent. Vibration modifications amplifies the preferred signal and blocks out interfering signals and noise. In cities where there is a lot of public transportation and lots of traffic air pollution runs extremely high. People are getting their lungs full of pollution and are in sometimes very unhealthy situations. Air filters need to be installed on these vehicles. A few of these vehicles maybe non polluting due to the fact they could be electric or hybrid automobiles, but for the ones running on gasoline or diesel fuel, the smell is terrible.  Traditional filters are very good at catching the pollutants that we can see. These traditional filters miss the ones we don’t see, even though we smell both and both are harmful to our health and environment. Research is being done with graphene, which is a  carbon-based nano-material.  Graphene has the ability to be hydrocarbon sticky and can be adjustable for air filtration systems with an absorption rate of 60:1 times its mass.  Research is finding new advances in graphene nano-materials to remove hydrocarbons and diesel fumes. Graphene enhanced filters make use of their nano-platelets which create  millions of filters at the molecular level, these graphene super nano-filters catch what common filters miss, to help clean up the air and make a clean environment.
Graphene filters work at the molecular level which means where there are air borne hydrocarbons the invisible particles will attach to the graphene filters.

Making Saltwater Drinkable Is Graphene’s Latest Miracle


This process, developed by MIT researchers, involves pushing saltwater through a one-atom-thick graphene filter covered in tiny holes that are just big enough for water to pass through, but small enough to block out salt

Drinking Water from Salt Water – Richard Hammond’s Engineering Connections – BBC Two

This is a wonderful video that is fun to watch! It is not overly scientfic but it shows you how you can filter sea water into drinking water very easily.
More about this episode: Richard Hammond unpicks the engineering DNA of aircraft carrier HMS Illustrious. In this clip, Richard explains how they make drinking water from salt water.

With water shortatge maybe in the future there will be large filtrations plants filtering sea water into drinkable water.

  Graphene has opened up a new technology for nano-science and the nano-technology world. Graphene is a member of the class of 2-dimensional materials. Because graphene is very thin it is easily controlled, it is used to make very good transistors and now, graphene has now found another use.  Research has found a type of graphene oxide filter that allows water to pass but not helium gasoline. Graphene is a type of carbon, which is a flat layer of carbon atoms tightly packed into a two-dimensional honeycomb arrangement. It’s so thin, it is  almost transparent and  a conductor of electrical energy. It  can do as well as copper and as a conductor of heat, it out performs all other materials. Because of graphene’s mechanical and chemical properties at the molecular scale it promises a lot of applications, which are being researched and tested. The filtration of water is part of this research.
Graphene is impermeable to everything but water, so therefore it makes the perfect water filter! Which finding a water filter that can be used with sea water, sewerage or gray water is important to our environment. Graphene oxide water filtration actually uses graphene oxide not graphene. In a good way graphene oxide is much easier to manufacture. Graphene oxide forms into single-atom-thick sheets, like graphene does, but then it stack ups, which is a good quality of graphene oxide, layer after layer, to form a laminate. Researchers are trying to prove that it is this laminate form that allows water molecules through the filtration system.  All types of tests have been done to see what is filtered by graphene filters. Even the most sensitive equipment was unable to register any negative results from these tests, only water vapor was left. The graphene oxide filter even prevented helium gas from escaping, which is extremely difficult to filter out. Graphene has been acknowledged as a wonderful part of the new nano technology.  Even though graphene is a a single layer of carbon atoms, it just may be the most conductive material in the world, both electrically and thermally. It really is tough and at the same time the thinnest material research has found so far.  The graphene oxide sheets are arranged so that between them there is room for exactly one layer of water molecules. No other atoms or molecules can get through because the graphene capillaries either shrink in low humidity or get clogged with the water molecules. Since helium is a superb detector of leaks, iit is used to ensure a space that will be under a vacuum has no substantial leaks. Trace minerals, calcium and magnesium can be added back into the water right after filtration for making the water beneficial for health reasons.

We need to find a way to filter water from waste water municpalities, sea water and grey water to make potable water. In the future with global warming becoming a very important issue so has clean drinking water become an important issue. With droughts come drinking water shortages. We are getting the technology from nano science to  find an inexpensive safe way to produce clean drinking water. In some instances we are reclycling water that is normally thought of as non drinkable, but with the new technology of graphene filters and creating water filtration systems we have this water to use, making it safe for drinking.
