Patterned polymeric structures have attracted significant interest for possible applications in the development of sensors, catalysis, and optical devices. Thus far, several strategies, based upon photolithography, electron beam lithography, and microcontact printing have been developed for generating polymer arrays. While useful for many applications, these methods do not allow one to control ...

This report describes ROMP: a Ring-based Occam Multi-Processor system, which has been constructed for the purpose of investigating techniques for compiling and executing parallel programs on multi-processor computers. ROMP runs Occam 2 programs. Occam channels are multiplexed onto a token ring which links the processors. Shared memory is used to give a very high potential data transfer rate bet...

The synthesis of cyclic polybutadienes using ring-opening metathesis polymerization (ROMP) was accomplished. A cyclic Ru alkylidene catalyst, where a terminal ligand was covalently linked to the Ru alkylidene, was used to polymerize either 1,5-cyclooctadiene (COD) or 1,5,9-trans-cis-trans-cyclododecatriene (CDT). Trace amounts of an acyclic impurity, 4-vinylcyclohexene, found in the COD led to ...

A series of alkene bearing small molecules were electrografted to the surface carbon fibers using in situ generation aryldiazonium salts. These used as an anchoring point for use Ring Opening Metathesis Polymerization (ROMP) a ‘graft from’ approach fiber modification. After modification, evaluation these modified epoxy resin, single fragmentation test, showed significant increases interfacial s...

One of the most effective synthetic pathways to produce unsaturated compounds and polymers, meant for both industrial pharmaceutical applications, is olefin metathesis. These useful reactions are commonly promoted by ruthenium-based precatalysts, namely second-generation Grubbs’ catalyst (GII) complexes bearing a styrenyl ether ligand, referred as Hoveyda–Grubbs’ (HGII). By altering steric elec...

The paper analyses the scientific research production of more than a thousand faculty members of Louis Pasteur University, large and well ranked in Europe. We take account of individual and collective determinants to explain individual productivity in terms of intensity and quality. We find that individual variables related to the position occupied are significant. The size of the lab plays neg...
