Determination of a kinetic model for the polyaddition of bisphenol A with an epoxide liquid resin

Solid epoxy resins are produced at Vantico SA by catalyzed reactions of a low-mol. wt. liq. resin (RBL) with bisphenol A (BPA). These reactions lead to solid epoxy resins, which are used in surface coatings or adhesives. The chain lengthening step (advance ...

Electrochemical oxidation of phenol at boron-doped diamond electrode

Christos Comninellis, Pierre-Alain Michaud, Marco Panizza

The electrochem. oxidn. of phenol at synthetic boron-doped diamond thin film electrode (BDD) was studied in acid media by cyclic voltammetry, chronoamperometry, and bulk electrolysis. In the potential region of water stability (E

Electrochemical oxidation of 3-methylpyridine at a boron-doped diamond electrode: application to electroorganic synthesis and wastewater treatment

Christos Comninellis, Pierre-Alain Michaud, Marco Panizza

The electrochem. oxidn. of 3-methylpyridine (3-MP) at synthetic boron-doped diamond (BDD) thin film electrode was studied in acid media by cyclic voltammetry and bulk electrolysis. The results showed that in the potential region of water stability there ca ...

Functionalised polymers for tissue engineering

Peter Frey

Methods for functionalising polymers for tissue engineering are disclosed in which a polymer matrix is activated to bind to biological materials such as cells by covalently bonding a hydrophilic polymer to carboxy groups of a polymer matrix. The hydrophili ...

Phthalocyanine-Sensitized Nanostructured TiO2 Electrodes Prepared by a Novel Anchoring Method

Ulf Anders Hagfeldt

A novel method for anchoring phthalocyanines substituted with ester groups onto nanostructured TiO2 films is described. Such phthalocyanines did not adsorb on nanostructured TiO2 film by the ordinary methods. In the authors' new method, the TiO2 film is pr ...

Surface modification of polyester films by RF plasma

Christoph Hollenstein, John Christopher Plummer, Nicolas Xanthopoulos

Plasma treatment of PET films was carried out under argon, followed by exposure to an oxygen atmosphere. The films underwent considerable changes in surface composition and morphology, as demonstrated by contact angle measurements, FTIR-ATR, AFM, and XPS. ...

Total synthesis and conformational studies of hapalosin, N-desmethylhapalosin and 8-deoxyhapalosin

Jieping Zhu

Hapalosin I (R1 = Me, R2 = OH), a 12-membered cyclic depsipeptide possessing MDR-reversing activity, and its analogs, N-desmethylhapalosin I (R1 = H, R2 = OH) and 8-deoxyhapalosin I (R1 = Me, R2 = H), have been synthesized using macrolactamization as an im ...

Determination of kinetics models for the polyaddition of bisphenol A with an epoxide liquid resin

Albert Renken

Solid epoxy resins are produced by catalyzed reactions of a low-mol.-wt. liq. resin (RBL) with bisphenol A (BPA). These reactions lead to solid epoxy resins that have many uses. The chain lengthening step (advancement reaction) is based on the reaction of ...

Hydroxyl radical ozone ratios during ozonation processes. I-The R-ct concept

Urs von Gunten

The ozonation of model systems and several natural waters was examined in bench-scale batch experiments. In addition to measuring the concentration of ozone (O-3), the rate of depletion of an in situ hydroxyl radical probe compound was monitored, thus prov ...

Ab initio molecular dynamics simulations of the gas-phase reaction of hydroxyl radical with nitrogen dioxide radical

Ursula Röthlisberger

The reaction between the hydroxyl radical and the nitrogen dioxide radical in the gas phase has been studied with ab initio mol. dynamics simulations based on d. functional theory. Nitric acid HONO2 and cis-cis peroxynitrous acid ONOOH are formed spontaneo ...
