Aromatic Hydrocarbon Giants-Graphenes

Graphenes are the large polycyclic aromatic hydrocarbons.They have got this name by their similarity to graphite.Even though they have been synthesized in the laboratory,recently, their applications are numerous.
However,they are used as a materials for special-purposes in electronics,the most.The great contribution for solving problems related to the synthesis of these large polyicyclic aromatic hydrocarbons has the German chemist Klaus Müllen.

He has dicovered the chemical reaction for obtaining the correctly certain isomers of graphene and a method for translating these into an easily soluble form.
Substitued graphene, also known as ´soluble graphite´ or ´liquid graphite´ is used in various modern high-tech devices.It is mainly used in places where light and electricity react with each other, such as solar cells,light detectors, photodiodes etc.

These are some of the potential applications of this hydrocarbon and possible features used:

-Room temperature distillation of ethanol for fuel and human consumption(its oxide membranes have been shown to be impermeable to all gases including helium, while simultaneously allowing water vapor to pass through the membrane as though no barrier were there)
-Single-molecule gas detection(thin polymer layer acts like a concentrator that absorbs gaseous molecules)
-Graphene nanoribbons(single layers of graphene cut in a particular pattern give them certain electrical properties)
-Graphene transistors(exhibits a pronounced response to perpendicular external electric fields, allowing one to build field-effect transistors)
-Graphene optical modulators(optical absorption of graphene can be changed)
-Integrated circuits(it has a high carrier mobility, as well as the low noise)
-Electrochromic devices(graphene oxide can be reversibly reduced and oxidized using electrical stimulus)
-Transparent conducting electrodes(it has the high electrical conductivity and high optical transparency)
-Reference material for characterizing electroconductive and transparent materials(1 layer of graphene absorbs 2.3% of white light-this parameter was used to compare different materials without the use of two independent parameters)
-Thermal management materials-Thermal interfacial materials(superior equivalent thermal conductivity and ultra-low interfacial thermal resistance between graphene and metal)
-Solar cells(highly transparent graphene films)
-Ultracapacitors(could be used to produce ultracapacitors with a greater energy storage density than is currently available)
-Graphene biodevices(it has modifiable chemistry, large surface area, atomic thickness and molecularly-gatable structure )
-Anti-bacterial(the sheets of graphene oxide are highly effective at killing bacteria such as E.Coli. It could be useful in applications such as hygiene products or packaging that will help keep food fresh for longer periods of time)
