A Blossoming Of Agrochemical Deals

Crop Protection: Consolidation hit off-patent agricultural chemical sector Marc S. Reisch Agricultural chemical makers went on a buying spree this year, targeting off-patent crop chemical businesses. Among the biggest consolidators was recently formed chemical firm Platform Specialty Products, which cut a deal in April to buy Chemtura’s AgroSolutions business for $1 billion. Then in August, […]

High-Purity Nanotubes Grown From Seed

Nanotechnology: Two new routes create specific types of single-walled carbon nanotubes with high purity Bethany Halford Scientists have speculated for decades about the potential applications of single-walled carbon nanotubes (SWNTs). With their characteristic strength, flexibility, and conductivity, these nanomaterials that resemble rolled-up chicken wire might one day feature prominently in solar cells and miniaturized electronic […]

Hydrogen Bonds: Real Or Surreal?

Microscopy: Bonds imaged by AFM last year may be an artifact of the technique, leaving the discovery in question Jyllian Kemsley The sighting of hydrogen bond interactions in atomic force microscopy (AFM) images, highlighted in C&EN last year, may be an experimental artifact. The images published by a group of researchers in China appear to […]

More Graphene Surprises

Material Science: Researchers are shocked to find that the thin carbon sheet can decompose and can conduct protons Mitch Jacoby Ultrathin films of carbon known as graphene have generated intense interest because of the potential applications enabled by the material’s outstanding physical and chemical properties. One of those properties, chemical stability, was called into question […]

Iridium Dressed To The Nines

Periodic Table: IrO4+ is the first molecule with an element in the +9 oxidation state Steve Ritter Before this year, the highest observed oxidation state of an atom in a molecule had been +8, which occurs in only a few tetroxide compounds—RuO4, OsO4, IrO4, and XeO4. These are molecules in which the central metal atom […]
