Formation and dissolution of gold nanocrystal superlattices in a colloidal solution

Article Abstract:

Synthesis of the colloidal form of gold nanocrystal superlattices was made possible by using dodecanethiol ligand as a medium for modifying their surfaces. Experimental results show that a substantial increase in electron density is associated with a corresponding increase in the rate of nanocrystal interaction. Nanocrystal samples that were exposed to high temperature did not exhibit superlattice or any other type of aggregate formation. On the other hand, those which were subjected to relatively low temperatures exhibited saturation which eventually led to the formation of superlattice structures.

pH dependence of the electronic structure of glycine

Article Abstract:

The experimental measurement of the near-edge X-ray absorption fine structure (NEXAFS) spectra of aqueous glycine for all relevant charge states and elemental K-edges is reported. The insights provided by the pH dependence have led to a reassignment of the previously reported nitrogen K-edge spectrum of vapor phase glycine.
