Graphene is one of the most perspective modern materials. 
Graphene is an atomic-scale honeycomb lattice made of carbon 
atoms and discovered only a few decades ago. 
How can we get it? There are two methods: mechanical and 
chemical. Technically, we can make graphene by sticking a piece of 
tape onto the ―lead‖ of a graphite pencil and then peeling the tape 
off. Graphene is not particularly useful in that form, however. 
Researchers want to make large sheets of graphene, which could then 
go next-generation electronics. 
How can we use it? Potential graphene applications include 
lightweight, thin, flexible, yet durable display screens, electric 
circuits, and solar cells, contaminant removals, water filters, 
waterproof materials, various medical, chemical and industrial 
processes enhanced or enabled by the use of new graphene materials 
and many others. 
Graphene sheets perforated by small holes have first been 
explored by researchers at MIT as potential candidates for water 
filtration. Holes with a diameter of 1 nanometre are big enough to let 
water molecules sift through, however small enough to stop any 
undesired chemicals. 
Pacific Northwest National Laboratory scientists are getting 
prepared to test graphene-enhanced lithium ion batteries that can 
charge your cell phone and power tools in minutes, not hours. 
Nobody has made night-vision contact lenses yet but here's a 
glimpse at how that technology might work, if it ever comes to be. 
University researchers have invented new graphene-based material 
that detects and emit a stronger infrared light. Graphene sensors have 
two advantages compared with the standard. The first one is that the 
optical sensors based on graphene require ten times less energy for 
work. The second advantage of graphene sensors is that they are 
1,000 times more sensitive. 
Graphene can be used as a very sensitive sensor detecting 
individual molecules in the air. The scheme of this sensor is that 
different molecules can be donors and acceptors, which changes 
resistance of graphene.

In May 2013 the creation of solar paint comprising graphene 
was announced. It absorbs energy from sunlight and transforms it 
into electricity. Solar paint was developed by scientists at the 
University of Manchester in cooperation with specialists from the 
National University of Singapore. It can cover the walls of houses 
and office buildings to generate electricity. 
Could you imagine a bulletproof vest with graphene? Not so 
easy to check the strength of the thin material through direct shots. 
Scientists from the University of Massachusetts have developed a 
miniature ballistic test to check the stability of graphene. It showed 
that graphene is in two times better than Kevlar. 
If equipped 300-seat Boeing 777 airliner with ultralight 
aerogels graphene-based parachutes, its weight would increase only 
by 60 kilograms. Scientists estimate that a ready device will weigh 
lighter than shirt. The porous material, created by a team of 
researchers led by Professor Gao Chao from Zhejiang University in 
China, consists of dried carbon oxide and graphene. Today, graphene 
aerogel is the lightest solid material in the world. 
On the other hand, we have health risks. Research at Brown 
University found out that graphene flakes are able to pierce cell 
membranes in solution. They were observed to initially enter via 
sharp and jagged points, allowing graphene to be internalized in the 
cell. The physiological effects of this remain uncertain, and this 
remains a relatively unexplored field. 
Every epoch has its own greatest discovery, which sets the 
pace and direction of progress many years ahead. For example, the 
metallurgy was the basis of the industrial revolution; invention of 
semiconductor transistor in the XX century made it possible the 
emergence of the modern computerized world. Will graphene be this 
miracle material of the XXI century and will we create                  
graphene-based devices, which we now can‘t even imagine? It may 
well be. Moreover, recently, Samsung announced that its scientists 
have discovered an inexpensive way for mass production of 
graphene.
