The
search for novel materials has always been
an area of great scientific and technological
interest, not merely from the vantage point
of research in basic sciences and engineering,
but also for applications in industrial
sectors like: electronics, medicine, aeronautics,
metallurgy, and mining, among others.
Materials designed for a given purpose
should carry out fail-free functions for
extended periods of time. Their production
should be easy and low cost with subsequent
processes as environmentally friendly as
possible. Additionally, contemporary life
has accustomed us to rapid global communication,
to efficient modes of transport, and to
a much longer life expectancy than ever
before. To a great measure, this is based
upon the existence of objects like the microchip,
weak and strong metal alloys, improved tools,
and other processes that make the aforementioned
possible. Is it probable that the benefits
supported by these advances become more
generalized than they are now? For this,
the issues of cost and viability to prepare
novel materials become crucial themes.
It is highly unusual for a material to
be useful just as it is provided by nature.
Generally, minerals need refinement and
processing to produce metals. Ceramic materials
are produced through complex processing
of raw materials and from their interaction
with heat. Careful synthesis is necessary
for the fabrication of most polymers. The
endless possibilities of combining known
materials give rise to composite materials.

Materials,
such as they are traditionally understood,
are macroscopic objects; nevertheless,
they are composed of atoms and molecules.
Hence, it is a characteristic trait
of many materials that their collective
behavior is completely different,
as is the case of magnetism, from
what one would expect given our knowledge
of the behavior of the individual
components. Most recently, the making
of materials at the nano-metric scale
has been made possible, attracting
notable interest due to their enormous
potential in the design of materials,
as well as to their interesting magnetic,
optical, and catalytic properties
and to their fascinating mechanical
behavior. |
Current doubts in materials research are
what stimulate CENM in the quest to understanding
materials, not merely at the final consumer
level, but also at a more profound scientific
level. CENM is also moved by inquiries such
as: what enables materials to respond to
external forces the way they do? Additionally,
is it possible to create materials with
pre-assigned properties on the basis of
a molecular scale? CENM, through experimental
techniques, will explore the answers to
these questions and will reach theoretical
understanding of the internal mechanisms
of materials. |
