Methyl formate presents a challenge for the conventional chemical mechanisms assumed to guide interstellar organic chemistry. Previous studies of potential formation pathways for methyl formate in interstellar clouds ruled out gas-phase chemistry as a major production route, and more recent chemical kinetics models indicate that it may form efficiently from radical-radical chemistry on ice surf...

There is a biomedical need to develop molecular recognition systems that selectively target the interfaces of protein and lipid aggregates in biomembranes. This is an extremely challenging problem in supramolecular chemistry because the biological membrane is a complex dynamic assembly of multifarious molecular components with local inhomogeneity. Two simplifying concepts are presented as a fra...

MOTIVATION The importance of fast and affordable DNA sequencing methods for current day life sciences, medicine and biotechnology is hard to overstate. A major player is Ion Torrent, a pyrosequencing-like technology which produces flowgrams--sequences of incorporation values--which are converted into nucleotide sequences by a base-calling algorithm. Because of its exploitation of ubiquitous sem...

Unlike the more established lithium-ion based energy storage chemistries, the complex intercalation chemistry of multivalent cations in a host lattice is not well understood, especially the relationship between the intercalating species solution chemistry and the prevalence and type of side reactions. Among multivalent metals, a promising model system can be based on nonaqueous Zn ion chemistry...

The molecular ion H3 1 is considered the cornerstone of interstellar chemistry because it initiates the reactions responsible for the production of many larger molecules. Recently discovered in dense molecular clouds, H3 1 has now been observed in the diffuse interstellar medium toward Cygnus OB2 No. 12. Analysis of H3 1 chemistry suggests that the high H3 1 column density (3.8 3 10 per square ...

Biography: Fulvio Cacace was born in Rome in 193 1 and received his undergraduate education at the University of Rome, as a student of Prof. G . Giacomello. Then followed postdoctoral experience at Uppsala, Brookhaven National Laboratory, and Kernforschungauslage Julich and teaching appointments at the Universities of Camerino and Viterbo.
