An Australian team has developed a new molecular sieve that allows carbon dioxide molecules to be trapped and stored. Contrary to the way molecular sieves usually work, allowing smaller molecules through, the new sieve acts like a trapdoor, and allows larger molecules through, blocking smaller ones. The team, led by professor Paul A. Webley of the University of Melbourne (Australia; www.unimelb.edu.au)...

For the first time, it has become possible to spin carbon nanotubes (CNTs) into a fiber that looks and acts like textile threads, yet has the electrical conductivity and strength of a metal. The breakthrough, which came after more than ten years of research, was published in the January 11 issue of Science by scientists from Rice University (Houston; www.rice.edu), Teijin Aramid B.V. (Arnhem, The...

Professor Kenichoro Itami and his group at Nagoya University (synth.chem. nagoya-u.ac.jp) have synthesized a cage-type carbon nano-molecule, Carbon Nano-cage, composed of 20 condensed benzene rings — C120H78. The group used a procedure it developed four years ago to synthesize carbon nano-rings with the ability to eliminate the distortion of ring-type benzene structures during synthesis steps. First...

A group of scientists from Fudan University (Shanghai, China; www.fudan.ac.cn) China, has reported what it claims to be the first example of artificial single-molecular water channels that can transport water across lipid membranes. Transmembrane water transport — through water channel proteins called aquaporins — is of crucial importance in living organisms because it regulates the osmotic...

For the first time, researchers from Riken (Saitama, Japan; www.riken.go.jp) have synthesized stable crystals (photo) of a so-called heavy ketone — a compound in which the carbon of the C=O bond is replaced by Si, Ge, Sn or Pb. These heavy ketones are highly reactive and prone to polymerization, which has made them difficult to synthesize and isolate to study...
