Mechanical spectroscopy in carbon nanotube reinforced ABS

Mechanical spectroscopy has been used to qualify possible improvements of the mechanical properties of acrylonitrile-butadiene-styrene-carbon nanotubes (ABS-CNTs) composites. The properties of ABS matrix are first investigated. Two relaxations that mark th ...

Pour plus de densité. AZF, Toulouse (F)

Jean Camuzet, Adrian Garcin

Désormais, la moitié de la population de notre planète est urbaine. Les métropoles s'étendent et la densification des zones déjà urbanisées s'accélère. La pression foncière incite investisseurs et pouvoirs publics à aménager des territoires jusque là délai ...

On the influence of "arm-on, arm-off" processes on alkene hydrogenation catalysed by a rhodium triphos complex

Paul Joseph Dyson

The influence of phosphane "arm-on, arm-off" assocn./dissocn. in rhodium catalyzed alkene hydrogenation using [Rh(COD)(k3-triphos)]PF6 {1, COD = cyclooctadiene, triphos = 1,1,1-tris(diphenylphosphanylmethyl)ethane} has been investigated by comparison of th ...

Continuous high-temperature polymerisation of methyl methacrylate

Thierry Meyer, Philip Nising

As the need for lower mol. wt. acrylates for specialty and molding applications increases, industry is looking for substitute prodn. processes. An alternative to the increasing of initiator and chain transfer agent concn. is working at higher temps. Howeve ...

Electropolymerisable bipyridine ruthenium(II) complexes: synthesis, spectroscopic and electrochemical characterisation of 4-((2-thienyl)ethenyl)- and 4,4'-di((2-thienyl)ethenyl)-2,2'-bipyridine ruthenium complexes

Ulf Anders Hagfeldt

Four new Ru polypyridyl complexes with mono- or di((2-thienyl)ethenyl) substituted bipyridines were synthesized. The complexes were characterized by NMR, elemental anal., UV-visible absorption and electrochem. (differential pulse and cyclic voltammetry). E ...

Contribution of anaerobic microbial activity to natural attenuation of benzene in groundwater

David Andrew Barry

Anaerobic biodegradation of hydrocarbons, using a variety of terminal electron acceptors (TEAs), is increasingly being reported both in laboratory studies and in the field. Of all the petroleum hydrocarbons, benzene is considered the most problematical due ...

Thermodynamic Evolution of Unsaturated Polyester-Styrene-Hyperbranched Polymers

The free energy of mixing during cure has been modeled for different blends of linear unsaturated polyester, styrene and allyl ether functional hyperbranched polymers. The molecular weight of the blend components has been implemented as measured by gel per ...

Kinetic modeling of free radical polymerization of styrene initiated by the bifunctional initiator 2,5-dimethyl-2,5-bis(2-ethyl hexanoyl peroxy) hexane

Albert Renken, Thierry Meyer, André Rouge

This paper deals with the kinetic study of bulk free radical polymerization of styrene initiated with the commercial bifunctional initiator 2,5-dimethyl-2,5-bis(2-ethyl hexanoyl peroxy)hexane (Lupersol 256). The polymerization kinetics is investigated by D ...
