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 ...
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, ...
Temperature Dependent Thermal Conductivity of Symmetrically Strained Si/Ge Superlattices
(ASME (American Society of Mechanical Engineers), 1999)
Experimental evidence for a significant thermal conductivity reduction has been reported in recent years for GaAs/AlAs, Si/Ge, and Bi2Te3/Sb2Te3 superlattices. Previously reported experimental studies on Si/Ge superlattices ...
The analysis of fatigue crack growth in glass/epoxy composites
(Kluwer Academic Publ, Dordrecht, 1997)
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 ...
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 ...
Application of modern technology in the production of paper for saving energy
(Editura Acad Romane, Bucuresti, 1998)
All researches conducted with the objective of energy savings in paper industry point out that today in Yugoslavia and South East Europe this industrial branch consumes 30-40% more specific energy than Western Europe. The ...
HREM observations of mechanical twinning in Cu-Ti alloys: Structure of incoherent and coherent twin interfaces
(Minerals, Metals & Materials Soc (TMS), 1997)
The flow of Cu-Ti alloys hardened by coherent β′ precipitates (Cu4Ti, D1a superstructure) is particularly interesting since these alloys show profuse twinning on multiple systems after small amounts of plastic flow by slip. ...
Raman scattering and infrared absorption in multiple boron-doped Ge dots
(American Institute of Physics Inc.American Vacuum Society, 1999)
Multiple boron-doped Ge quantum dots are investigated. The structure, which consists of 20 periods of Ge quantum dots stacked with 6 nm Si spacers, is grown on a Si (100) substrate by solid source molecular beam epitaxy. ...
Raman scattering from a self-organized Ge dot superlattice
(American Institute of Physics Inc., 1999)
We present a Raman scattering study of a self-organized Ge dot superlattice. The structure, which consists of 20 periods of Ge quantum dots sandwiched by 6 nm Si spacers, is grown on a Si (100) substrate by solid source ...
