New Molecular Constructions Discovered in Nanocapsules

Researchers at Tsinghua University in China and Brown University have discovered that nanocomposites composed of boron and lanthanide elements form highly stable and symmetrical structures with interesting magnetic properties.

Findings published in the National Academy of Sciences Reports on Monday, July 9, show that nanoparticles may be useful as molecular magnets or may be coupled to magnetic nanotubes.

Lai-Sheng Wang, a professor of chemistry at Brown University and an author of a study on the subject of work, describes the use of boron lanthanides in electronic and other applications but he has not previously studied the nanocomposites of boron lanthanides.


Wang continued, "We have just begun to investigate these nanoparticles, and here we have discovered that boron and lanthanide atoms have an interesting" reverse sandwich "structure with the right combination.

Sandwich constructions are welcomed in complexes in which two planar aromatic hydrocarbon molecules surround a single metal atom, and in 1973 the discovery was awarded the Nobel Prize. Wang explains, "It was known that reverse sandwich structures were formed in uranium-organic molecular complexes, but this was first discovered in borantanides."

Wang's laboratory used a technique called photoelectron spectroscopy to study nanocarbons made from different chemical elements. Technically, atomic clusters contain a high-power laser-encapsulation. Every zap takes an electron out of the coin. By measuring the kinetic energy of released electrons, researchers can understand how a cluster of atoms are connected together and understand the physical structure of the cone. To find out, Wang compared photoelectron spectra with theoretical calculations from quantum chemist Professor Jun Li and Tsinghua University.
