Science Breakthroughs The Koyal Group InfoMag reviews: Nanotech Discovery

Boron Buckyball Structure Discovered

Nanotechnology 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.

Koyal Group Info Mag – A new look at the Big Bang, moments later


The theory of cosmic inflation was proposed by MIT physicist Alan Guth in 1980, because simpler models of the Big Bang could not explain some features of the universe as it appears today, such as its uniformity.

 

Inflation proposes that there was an initial exponential expansion of the universe caused by a repulsive form of gravity — opposite the normal way of thinking about gravity as an attractive force.

 

As the universe continues to expand today, “what we see now is still a coasting expansion, originating from the Big Bang,” Guth said in an interview.

 

As Guth’s initial idea has been refined and developed by other scientists over the years, its predictions seemed to be borne out. But there was still no direct evidence for inflation and it was unclear whether the theory would ever have proof to bolster it. The energy needed to re-create the conditions of the early universe in a particle accelerator — 10 trillion times higher than what is produced at the Large Hadron Collider in Switzerland — were so high that it was unfeasible.

 

The Harvard-led team took a different approach. One prediction of the theory is that the rapid expansion would have left behind a fingerprint — a particular pattern of polarized light in the cosmic microwave background. This faint light all across the sky is the afterglow of the Big Bang, emitted 380,000 years after the explosion, and the telltale pattern was created when the light interacted with gravitational waves.

 

Using a telescope called BICEP2 at the South Pole, the team claims to have detected that swirly polarization pattern, called B-mode polarization. If confirmed by other experiments, it will be strong evidence of inflation and help guide scientists to which particular version of inflation is the correct one.
