Introduction to Nanotechnology


One of the greatest challenges to mankind in the 21st century is its over-reliance on the
diminishing fossil fuels (coal, oil, natural gas) as primary energy sources.Fossil fuels are nonrenewable
resources that take millions of years to form. Consequently their reserves are depleted
much faster than new ones are formed and/or discovered.The rapid evolution of nanoscience and
nanotechnology (the study and control of materials and phenomena at length scales between 1
nm to 100 nm) during the past two decades has demonstrated that nanotechnology holds the key
to many of the technological advancements in the energy sector.The most promising application
fields of nanotechnology or nanomaterials for the energy production domain will be in
photovoltaics and hydrogen conversion (hydrogen production, fuel cells) .Nanotechnology
intervenes at a number of stages of the energy flow that starts from the primary energy sources
and finishes at the end user.
