Ado Jorio, a physicist at the Federal University of Minas
Gerais, Brazil, has been named the recipient of the 2011 ICTP
Prize.
The Prize recognizes Jorio's Raman spectroscopy work on single
carbon nanotubes, clarifying their electronic and vibrational
properties. Carbon nanotubes, which were discovered in 1991, are
extremely thin, hollow cylinders whose diameter is about 100,000
times smaller than a human hair. They are extremely strong
materials, very good thermal conductors, and can behave as metals
or semiconductors, properties that make them an important
ingredient in the manufacturing of electronic devices and
light-weight materials.
Raman spectroscopy is a technique that measures the frequency of
both incident light (light striking a surface) and emitted light as
it interacts with a given substance. These measurements can
tell a lot about the substance, such as its mechanical, elastic,
thermal and electronic properties, thus making the technique a key
in discovering new applications for carbon nanotubes.
The fact that Jordio's experimental work is being done in a
developing country shows how far countries like Brazil have come in
the development of their science capacity, according to ICTP
scientist Erio Tosatti. "First class experimental work is more of a
rarity in the South of the world than theory work -- theorists can
usually survive scarcity of resources and of coherent planning more
than experimentalists. Jorio appears to be a remarkable researcher
and a role model for many in his continent and elsewhere," said
Tosatti.
Jorio's main research interest is in the physics of
nano-materials. He is an associate professor in the Department of
Physics at the Federal University of Minas Gerais, having earned
his PhD at the same university in 1999. He worked for two years as
a post-doctoral fellow at the Massachusetts Institute of Technology
(MIT), Cambridge, USA.
ICTP's Scientific Council created the Prize in 1982. It recognizes
young scientists (under 40) from developing countries who work and
live in those countries and who have made outstanding and original
contributions in physics or mathematics. The Prize includes a
sculpture, certificate and a cash award of €3,000. To view the full
citation of Jorio's award, as well as a list of past winners, see
the ICTP Prize webpage. An award
ceremony for Jorio will take place at ICTP's Trieste campus in
August.
Each year, the ICTP Prize is given in honour of a scientist who
has made outstanding contributions to the field in which the Prize
is given. The 2011 ICTP Prize honours Praveen Chaudhari (1937 -
2010), chairman of ICTP's Scientific Council from 1998 to 2002.
Chaudhari made fundamental contributions to condensed matter
physics and material science. He worked on the structure and
properties of amorphous solids, mechanical properties of thin
films, defects in solids, quantum transport in disordered systems,
superconductivity, liquid crystal alignment on substrates, and on
the magnetic monopole experiment. One of his main achievements is
the discovery and development of amorphous magnetic materials,
which are the basis of erasable, read-write, optical storage
technology.
