The study of the interaction of nucleic acid molecules with mineral surfaces is a field of growing interest in organic chemistry, origin of life, material science and biotechnology. We have characterized the adsorption of single-stranded peptide nucleic acid (ssPNA) on a natural pyrite surface, as well as the further adsorption of ssDNA on a PNA-modified pyrite surface. The characterization has been...
The adsorption of S-histidine on gold and copper well-defined surfaces has been characterised by reflection absorption infrared spectroscopy (RAIRS), a surface technique that gives chemical as well as orientational information. Analyses were carried out in a UHV chamber. The RAIRS data are in agreement with the following conclusions. Under low pressure of histidine, 10 −8 mbar, histidine molecules...
Silicon carbide, SiC, is a refractory material which shows a high thermal conductivity. Therefore, a better thermal stability of both the catalytic active phase and of the support for the SiC supported metallic catalysts can be expected for reactions occurring at high temperature and/or for highly exothermic reactions working with high turnover frequency. Various Pd based catalysts have been prepared...
