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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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
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. ...
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 ...
