Direct observation of CF2 insertion into the carbon- metal bond on Cu(111)

Article Abstract:

The vibrational spectroscopic identification of stable surface intermediates, CF2 (sub ad) and CF2CF3 (sub ad) on Cu(111) is reported. At about 300 K, together with the CF2 coupling pathway, the Cu- CF2CF3 species undergo a beta- fluoride elimination reaction to liberate tetrafluroethylene (CF2=CF2) into the gas phase as the final product.

Chemical vapor deposition of mercury on alkanedithiolate self-assembled monolayers

Article Abstract:

The selective deposition of mercury (Hg) onto self-assembled dithiols via a chemical vapor deposition (CVD) process is described. The determination of the nanosized-droplets formation of Hg on alkanedithiolate self-assembled monolayers (SAMs) is demonstrated using quartz crystal microbalance (QCM) technique.

The simple cubic structure of ruthenium clusters

Article Abstract:

Density-functional theory with a plane wave basis set was used to study ruthenium clusters of up to 64 atoms. The study revealed that atoms in similar bonding environments have similar binding energies.
