Delamination detection in woven composite laminates with embedded optical fibers
(Wiley-VCH Verlag Gmbh, Weinheim, 2001)
Thermal conductivity of symmetrically strained Si/Ge superlattices
(Academic Press Ltd., 2000)
This paper reports temperature-dependent thermal conductivity measurements in the crossplane direction of symmetrically strained Si/Ge superlattices, and the effect of doping,
period thickness and dislocations on the ...
Structural and crystallization characteristics of K 2 O· TiO 2 ·3GeO 2 glass / Strukturní a krystalizaèní charakteristiky k2o·tio2·3geo2 skel
(Institute of Chemical Technology, 2005)
Structure and crystallization of K 2 O·TiO 2 ·3GeO 2 glass have been investigated by means of Fourier transform infrared spectroscopy (FTIR), differential thermal analysis (DTA), differential scanning calorimetry (DSC), ...
Pulse and direct current plating of Ni-W alloys from ammonia-citrate electrolyte
(Elsevier, 2006)
The effect of the potential of deposition and electrode rotation rate on current efficiency and partial current density of nickel deposition from ammonia-citrate electrolyte with and without tungstate ions was investigated. ...
Stress field analysis in composite laminates with embedded optical fiber
(Trans Tech Publications Ltd, Durnten-Zurich, 2000)
A typical intensity-modulated optical fiber sensor system consists of a light source, a sensing device, within which the intensity of light is altered by the measurand in some way, a detector to measure the intensity of ...
Aging of the over-voltage protection elements caused by over-voltages
(Microelectronics Reliability, 2002)
The aim of this work is examining the influence of the number of the activation-over-voltage pulses to the aging of over-voltage protection elements. Both non-linear (gas-filled surge arresters (GFSA), varistors, over-voltage ...
Synthesis and characterization of poly(ester ether siloxane)s
(John Wiley and Sons Ltd, 2006)
A series of novel thermoplastic elastomers based on ABA-type triblock prepolymers, poly[(propylene oxide)-(dimethylsiloxane)-(propylene oxide)] (PPO-PDMS-PPO), as the soft segments, and poly(butylene terephthalate) (PBT), ...
Modeling boron separation from water by activated carbon, impregnated and unimpregnated
(Roma : Società chimica italiana, 2000)
The sorption of boron from boric acid water solution by impregnated activated carbon has been studied Barium, calcium, mannitol, tartaric acid and citric acid were used as chemical active materials. All processes were ...
A kinetic study of the thermal degradation of ammonium species inside a 3D zincophosphate
(Elsevier Science Bv, Amsterdam, 2006)
Ammonium ions remain inside the 3D zincophosphate framework after the hydrothermal crystallization. These species in co-operation with sodium cations exert a specific templating role in the formation of the open-framework ...
Dielectric and piezoelectric properties of the mechanochemically prepared PZT ceramics
(Kluwer Academic Publishers, 2004)
Mechanochemical synthesis was applied to obtain nanocrystalline powders of composition Pb(Zr0.52Ti0.48)O-3 (PZT). Milling was performed in a planetary ball mill using vials and balls made of zirconia or steel-in order to ...
