Preparation of Well-Defined Ibuprofen Prodrug Micelles by RAFT Polymerization

Jeffrey Alan Hubbell, Jutta Christine Wandrey, Urara Hasegawa

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used to treat acute pain, fever, and inflammation and are being explored in a new indication in cancer. Side effects associated with long-term use of NSAIDs such as gastrointestinal damage and elevat ...

Sub-picosecond delocalization in the excited state of conjugated homopolymers and donor–acceptor copolymers

Natalie Renuka Banerji

In this feature article, we review and examine evidence that the primary photoexcited species in conjugated polymers is considerably delocalized. Localization occurs via a series of complex relaxation mechanisms on the

Styrene oxidation by hydrogen peroxide in ionic liquids: the role of the solvent on the competition between two Pd-catalyzed processes, oxidation and dimerization

Paul Joseph Dyson, Cinzia Chiappe

A series of hydrophilic N,N-dimethylpyrrolidinium-and N,N-dimethylpiperidinium-based ionic liquids (ILs) have been prepared and applied as reaction media in the Wacker oxidation of styrene by hydrogen peroxide using PdCl2 as the catalyst. The efficiency of ...

Synthesis of Unusual Oxime Ethers by Reaction of Tetranitromethane with B-Alkylcatecholboranes

Philippe Renaud, Kurt Schenk

The reaction of tetranitromethane with B-alkylcatecholboranes leads to the formation of unusual dinitrooxime ethers. A tentative mechanism is provided, which suggests the involvement of extremely fast addition of alkyl radicals to tetranitromethane. The su ...

Metallocene Catalyzed Polyolefins For Improving Thermal And Mechanical Properties Of Bitumen Blends

John Christopher Plummer, Chiara Spadaro

Bitumen is a complex viscoelastic material used as a binder in applications ranging from road paving to waterproof membranes for roofing [1]. In such applications, bitumen is often blended with a polymer in order to improve its elasticity. The resulting po ...

Mechanical spectroscopy in carbon nanotube reinforced ABS

Daniele Mari, Robert Schaller

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 ...

Chelating NHC Ruthenium(II) Complexes as Robust Homogeneous Hydrogenation Catalysts

Gabor Laurenczy, Antonia Neels

A series of ruthenium(II) N-heterocyclic carbene chelate complexes were prepd. by using bidentate chelating alkene-carbene, thioether-carbene, carboxylate-carbene and bis-carbene ligands. Metalation of 1-R-3-X-imidazolium salts (1-3, R = Me, X = allyl, MeS ...

Fracture mechanisms in polystyrene/laponite nanocomposites prepared by emulsion polymerization

John Christopher Plummer, Riccardo Ruggerone

Transmission electron microscopy (TEM) has been used to investigate the effect of laponite clay on microdeformation in thin latex-based polystyrene (PS) films, in which the laponite was concentrated at the original interfaces between the PS particles. At r ...

Effect of cell media on polymer coated superparamagnetic iron oxide nanoparticles (SPIONs): Colloidal stability, cytotoxicity, and cellular uptake studies

Heinrich Hofmann, Jatuporn Salaklang, Alke Fink, Benedikt Steitz, Andrija Finka

The influence of the composition of the polymer coated polyvinyl alcohol (PVA), vinyl alcohol/vinyl amine copolymer (A-PVA) and polyethylenimine (PEI) coated superparamagnetic iron oxide nanoparticles (SPIONs) on the colloidal stability, cytotoxicity and c ...
