Lets now look what you can find in the book. Firstly, the author provides reader with overview of structure of matter and very basic of quantum physics. Those are necessary for understanding of graphene. Then the auhtor discusses history of graphene discovery and finally, he presents application of the graphene, ranging from electronics to strong materials and molecular sieves for water desalization.
Despite predominantly positive feeling from the book, I have to show few examples of inaccuracies I found during the reading:
a) Explanantion how a diode works: "However, if the circuit is connected other way, the excess electrons on the n-side repel any furhers electrons, so current won't flow". Actually, in this case a positive voltage is connected to n-side. As a result, electrons are drained from the diode and depleted area between p-side and n-side of the diode becomes larger. So there is no excess of electrons but their lack.
b) "one of the benefits of capacitor's ability to lose DC is to filter out unwanted noise and leave the pure wave behind". In fact noise has usually high frequency. As frequency increases, a capacitor's impedance decreases and those high frequencies can be filtered out.
c) "graphene supecapacitors would allow electric cars to be recharged in minutes, so we can look forward to greener transport" I know that everything has to be green nowadays and I agree that we have to protect our planet. However, the author's proposal of using supercapacitors has many technical difficulties, mainly very high electric current would be needed for such rapid recharging (hundreds, maybe thousands, Amperes) and you have to rebuild a grid to cope with such hihg currents firstly.

Price too high for 160 page book even that from publication house hardly known.
