Graphene
, a single atomic layer of carbon atom arranged in an honeycomb pattern,

is
currently considered o
ne of the most promising materials for new technologies, potentially
as revolutionary as plastic was i n the middle of past century. Graphene is extremely robust
and light, capable of being model
l
ed i n a number of different shapes (fullerenes,
nanotubes, na
noribbons, nanosponges) and has unique electronic properties that makes it
an extremely efficient heat and current conductor.
In this lecture I’ ll summarize the main
results achieved so far
, particularly i n optoelectronics

[1] and energy research areas
and

the most promising perspective directions in the graphene roadmap
for the next decade
[2]
. To offer specific examples I
wi ll concentrate on two specific applications: i) a graphene
field
-
effect transistor for efficient broadband THz detection [3] and i
i)
a corrugated
graphene system

for efficient adsorption and release of hydrogen to be

used i n a fuel cell
device [4
