Preparation of aluminophosphate molecular sieves in the presence of nickel( II) and copper( II)
(Butterworth-Heinemann, 1991)
Nickel(ll)-substituted aluminophosphates of structure types 21 and 12 (NiAPO-21 and NiAPO-12) have been prepared hydrothermally in the presence of ethylenediamine as the template. U.v.-visible spectroscopy of NiAPO-21 ...
Structure optimization of polylactide microcapsules for controlled drug release
(Trans Tech Publications Ltd, Durnten-Zurich, 1998)
The influence of starting material properties on physical characteristics and drug release kinetics of poly-L-lactide microcapsules was investigated. The density, the distribution of the diameter size of microcapsules, the ...
Thermal investigations of some AlPO and MeAPO materials prepared in the presence of HF
(Elsevier, Amsterdam, 1997)
Hydrothermal synthesis of chabazite-like AlPO4 in a fluoride medium, using piperidine as the structure directing agent, is also successful in the preparation of transition-metal-modified AlPO products. The transition metal ...
Gas Chromatographic Retention Indices for the N-methyl-N-substituted Benzamides on Capillary Columns, Molecular Retention Index / Gasno hromatografski molekularni retencioni indeks N-metil-N-supstituisanih benzamida
(Banja Luka : Društvo hemičara i tehnologa Republike SrpskeBanja Luka : Tehnološki fakultet, 1997)
Gas chromatographic molecular retention indices for series of 20 synthesized N-methyl-N-substituded benzamides on DB-1, DB-5 and DB-WAX capillary columns isothermal at 170. 190 and 200 ⁰C were determined and the basis of ...
Processing of composite rod with embedded optical fiber
(Kluwer Academic Publ, Dordrecht, 1998)
Heat-treated iron(III) tetramethoxyphenyl porphyrin supported on high-area carbon as an electrocatalyst for oxygen: I. Characterization of the electrocatalyst
(Electrochemical Soc Inc, Pennington, 1998)
Iron(III) tetramethoxyphenyl porphyrin chloride adsorbed on the Black Pearls carbon (FeTMPP-Cl/BP) was heat-treated at temperatures from 200 to 1000°C in Ar atmosphere and characterized by using cyclic voltammetry, X-ray ...
Kinetics of O-2 reduction on a Pt electrode covered with a thin film of solid polymer electrolyte
(Electrochemical Soc Inc, Pennington, 1997)
The kinetics of O-2 reduction on both oxidized and reduced Pt rotating disk surfaces covered with thin films (1 to 15 mu m) of recast polybenzimidazole (PBI) or Nafion have been examined in 0.1 M aqueous solutions of H3PO4, ...
Composite rods with embedded optical fibre - Modeling and evaluation
(Trans Tech Publications Ltd, Durnten-Zurich, 1998)
An experimental facility for composite rod manufacturing by vacuum molding technique with embedded optical fibres has been designed and built. A mathematical model for composite rods, with embedded optical fibres, formation ...
An intensity based optical fibre sensor for flexural damage detection in woven composites
(Sage Publications Ltd, London, 1999)
Flexural deformation of the composite laminate and the integrity of the embedded optical fibres under three-point bending load were monitored. Signal attenuation in optical fibres was used as the damage indicator. The ...
Oxygen reduction on iron-Part VI. Processes in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1994)
The kinetics of oxygen reduction were studied on passivated iron in borate buffered and unbuffered solutions of pH ranging from 7.4 to 13.8. A rotating disk electrode was employed. The O2 reduction on iron under these ...
