Humans first used copper about 10,000 years ago. A copper pendant discovered in Northern Iraq is thought to date back to around 8700 BC. Prehistoric man probably used copper for weapon making. Ancient Egyptians too seemed to have appreciated the corrosion resistance of the metal. They used copper bands and nails in ship building and copper pipes were used to convey water. Some of these artifact...

In the past half century, radioastronomy has changed our perception and understanding of the universe. In this issue of PNAS, the molecular chemistry directly observed within the galaxy is discussed. For the most part, the description of the molecular transformations requires specific kinetic schemes rather than chemical thermodynamics. Ionization of the very abundant molecular hydrogen and ato...

The melt-phase synthesis of dioctyltin (IV) and triphenyltin (IV) benzoates were carried outusing stoichiometric amounts of benzoic acids and the corresponding organotin (IV) compounds.The reagents were ground together in a mortar and fed into a boiling glass tube. A cannula tubewas inserted into the boiling tube to discharge accumulated gaseous products. A syringe ensureda continuous flow of d...
