Nanoscience owes much to the discoveries of world renowned physicist Dr. Sumio
Iijima, who pioneered the use of high resolution transmission electron microscopy
(HRTEM) to characterize nanomaterials in the early 70s and successfully imaged
carbon nanotubes in the early 90s.
Although he has used JEOL TEMs for the past four decades, Dr. Iijima visited
JEOL USA this March for
the first time following a speaking engagement at MIT's Center for Materials
Science and Engineering.
Dr. Iijima's accomplishments are many, beginning with his groundbreaking
work at Arizona State University and later at the Research Development Corporation
of Japan and at NEC. He produced the first atomic resolution micrographs with
the HRTEM, characterized the structure of crystalline solids and imaged small
clusters in the structure of gold particles. He looked at short-range order
in carbon specimens and his micrographs validated the structure of C60. In 1991,
he published a paper on the crystalline structure of carbon nanotubes.
The discovery of carbon nanotubes has fueled intense research in nanoscience
and transformed knowledge of materials that are developed to benefit society.
"Science is always looking for something new," Dr. Iijima mused.
"Like the discovery of the transistor, small things become giant and the
seeds begin to grow."
Iijima admits to always thinking of microscopy as a hobby - not a job
- and his instruments of choice are the TEM, and, when not investigating nanomaterials,
"We're honored to have such a distinguished leader in the field
of nanoscience visit with us," said Bob Santorelli, CEO of JEOL USA, who
hosted the visit along with Shinichi Watanabe, Chairman; Peter Genovese, President;
and Hisao Wada, Vice President.
Dr. Iijima was recently honored as a guest of the Emperor and Empress of Japan,
and was presented with the 2009 Order of Culture award for materials science.
Iijima has also received the prestigious Kavli prize in 2008, Spain's
2008 Prince of Asturias Award, and the 2007 Balzan Prize for Nanoscience. He
was elected as a U.S. foreign member of the U.S. National Academy of Science
in 2007, and received the 2002 Benjamin Franklin Medal in Physics. Iijima is
currently a professor at Meijo University, director of the AIST/Nanotube Research
Center, Senior Research Fellow at NEC, and Dean of Sungkyunkwan Advanced Institute
of Nanotechnology in Seoul, Korea.
