President's Message: Each of us has a personal stake in the advancement of chemistry and letting others know the value of our science.

Here are the first measurements of the yields of β-hydroxynitrates and dihydroxynitrates from NO_x and linear alkenes in secondary organic aerosols, an important natural air pollution source.

Some carbon nanotubes are harvested from “forests” grown by water-assisted chemical vapor deposition from engineered catalysts.

Here’s a general synthesis of heterocyclic ethenyl C-nucleosides that can recognize inverted base pairs in a DNA triple helix. This may be a tool for gene suppression therapy.

Combining three analytical methods allowed researchers to verify that the patina on a 14th-century Moorish wall in Granada, Spain, was made from CaCO₃ and powdered burnt animal bones.

Synthetic water-soluble polymers with hydroxyl-containing side chains show biological antifreeze properties and may eventually be used to improve frozen food texture.
