was advanced massively after the discovery of the original Buckyball in 1985
Scientists working with different molecular structures
of Boron have discovered a configuration that resembles the
Buckminsterfullerene, often referred to as the Buckyball, a structure that has
become extremely important in the development of nanotechnology. The new
material is just as hollow as the Buckball and could also have important
implications in the development of nanotech.
The research was carried out by scientists
from Brown University, along with colleagues in Shanxi University and Tsinghua
University in China. Their discovery could have a profound impact on
the future of nanotechnology, but for now there is no obvious usage for the
molecular structure they discovered.
Endless
combinations achieve result
There has been a theoretical model for a
boron molecule with similar properties to the Buckyball, but it had not been
observed in experiments until the work by these researchers. The research
involved the computer modelling of over 10,000 structures of Boron, identifying
each by its binding energy.The energies of actual molecules were then tested
using a process called photoelectron spectroscopy, allowing the structures to
be identified.
The experiment returned two 40-atom
structures formed by Boron. The first is the aforementioned ball-shaped
cluster. The second is described as a semi-flat molecule by the researchers.
The boron ball is of the most importance because of the theoretical model that
has pointed to it for years, and the fact that it resembles the Buckyball, the
progenitor of so many nanotechnology discoveries.
The 40-atom hollow structure is being called
a borospherene by the scientists that discovered it. A paper concerning its
discovery and the experiments that led to it, appears in the scientific journal
Nature Chemistry.
Buckyball:
New material may lead to new discoveries
The Buckminsterfullerene was discovered in
1985 and gave rise to much of nanotechnology’s foundation. The structure
spurred the search and
discovery of other forms of carbon with unusual properties.
Carbon nano-tubes, a science fiction answer to many of the world’s problems and
graphene, a thin layer of carbon with incredible strength, that has been touted
as one of the material s that will define the twenty-first century, were both
discovered immediately after the Buckminsterfullerene.
Lai-Sheng Wang, a professor of chemistry at
Brown University, was one of those who led the research. He has no idea about
the applications of the molecule, but is proud of the achievement, and excited
by it, in and of itself. According to the researcher, “As a chemist, finding
new molecules and structures is always exciting. The fact that boron has the
capacity to form this kind of structure is very interesting.”
“Of course if it turns out to be useful that would be great, but we don’t know yet. Hopefully this initial finding will stimulate further interest in boron clusters and new ideas to synthesize them in bulk quantities.” Nanotechnolgy is still a very young science and discoveries like this one may help to form the basis for many discoveries later on. Just as the Buckball spurred the discovery of incredible carbon structures, the borospherene may allow nanotechnology to expand its purview.
