Chemical salt reactions as algebraic hyperstructures

A salt metathesis reaction is a chemical process involving the exchange of bonds between two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations. Hyperstructure theory is studied from the theoretical point of view and for its applications. In this paper, we provide some examples of hyperstructures associated with salt m...

Gas-surface chemical reactions at high collision energies?

Most gas-surface chemical reactions occur via reaction of adsorbed species to form a thermal-energy ( approximately kT) product; however, some instances exist where an energetic projectile directly reacts with an adsorbate in a single-collision event to form a hyperthermal product (with a kinetic energy of a few eV). Here we show for the first time that 30-300 eV F(+) bombardment of fluorinated...

First-principles study of chemical reactions at metal surfaces

We have studied the adsorption state and the hydrogenation process of formate on clean and Zn-deposited Cu(111) surfaces by using DFT-GGA-pseudopotential calculations. After the deposition of Zn on the Cu(111) surface, the Zn atom is substitutionally adsorbed in the first layer of the Cu surface and Cu-Zn surface alloys are formed which is in agreement with experimental results. However, our ca...

Single-molecule chemical reactions tracked at the atomic-bond level.

On the right track: Recent advances in noncontact atomic force microscopy (nc-AFM) have enabled the bond-resolved imaging of reaction pathways. In particular, unprecedented insights into complex enediyne cyclization cascades on silver surfaces were gained by single-molecule imaging.
