Electrochemical and Surface Characterization of pH Sensor Based on Bisulfate-Doped Poly(pyrrole)
(Wiley, 1997)
Pyrrole was electrochemically polymerized on glassy carbon support in NaHSO4 solutions under different conditions (method applied, concentration of monomer, concentration of the main solution, thickness of the film). These ...
Nickel film orientation change by nitrogen ion bombardment during deposition
(Elsevier, 1997)
The influence of nitrogen ion bombardment during e-beam triode ion plating of nickel on the microstructure and film orientation has been investigated. The deposition variables explored were the ion current density and ...
Characteristics of an avalanche photodiode with a spherical contact surface
(IOP Publishing, 1997)
The work presents an analysis of an avalanche photodiode (APD) with a spherical contact surface. We calculated the dependence of the avalanche multiplication and noise parameters on the incident light wavelength. Multiplication ...
Reduction of carbon dioxide on ruthenium oxide and modified ruthenium oxide electrodes in 0.5 M NaHCO3
(Elsevier, 1997)
Electrochemical reduction of carbon dioxide is still of great interest in the fields of theoretical and applied electrochemistry. Ruthenium is one of the metals with an intermediate hydrogen evolution overpotential which ...
The ωσ method: A new contactless comparison method for measuring electrical conductivity of nonferromagnetic conductors
(AIP Publishing, 1997)
A novel, very simple, eddy current method for measuring the electrical conductivity of nonferromagnetic conductors is described. This method is relative, i.e., we measure the ratio of conductivities of two samples of the ...
Far infrared properties of PLZT ceramics
(Springer, 1997)
Far infrared and mid-infrared reflectivity measurements have been made of lead titanate zirconate (PLZT) ceramics at room temperature in the frequency range 40–1500 cm-1. Kramers-Krönig analysis and a fitting procedure ...
The influence of the sintering regime on the stability of the SmCo5 phase
(Elsevier, 1997)
The purpose of this investigation was to establish the correlation between the sintering conditions (temperature and time) and the stability of the SmCo5 phase, expressed by the intensity of its most important diffraction ...
X-Ray Analysis in the Optimization of the Sintering Process of SmCo5 Magnets
(Sintering Society, 1997)
The content of the SmCo5 phase, as the carrier of magnetic properties, was controlled by X-ray diffraction analysis. The content of the SmCo5 phase, as a function of sintering time and temperature, under constant heat ...
Thermoelastic and electronic strain contributions to the frequency transmission photoacousticeffect in semiconductors
(The American Physical Society, 1997)
The photoacoustic effect is investigated as a function of the modulation frequency in a transmission detection configuration for semiconductor samples. The theoretical model for this configuration is given for the thermal ...
Thermal and Electronic Transport Properties of Single Crystal PtSb 2 Obtained by the Photoacoustic Method
(Institute of Pure and Applied Physics, 1997)
Single crystal PtSb2 ingots were synthesized using the Bridgman technique. Electronic transport properties and thermal diffusivity of PtSb2 sample were determined using the photoacoustic (PA) method with transmission ...
