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 ...
Sinterovani magneti tipa SmCo5
(Savez inženjera metalurgije Srbije, 1997)
U toku istraživanja tehnološkog postupka sinterovanih magneta tipa SmCo5 i izrade laboratorijskog modela definisani su tehnološki parametri za svaku fazu postupka dobijanja. Za izradu SmCo5 magneta korišćene su tehnike ...
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 ...
One dimensional Si-SiO2 photonic crystal with defects intended for use in infrared spectral region
(Institute of Electrical and Electronics Engineers (IEEE), 1997)
Abstract
Based on our detailed theoretical analysis we fabricated 1D Si/SiO2 photonic crystals with donor and acceptor defects. We observed their photonic band-gaps and defect modes by measuring the infrared transmission ...
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 ...
The electrocatalytic properties of the oxides of noble metals in the electro-oxidation of some organic molecules
(Elsevier, 1997)
The electro-oxidation of organic compounds on gold and silver electrodes can occur either in a potential range more negative than that where the metal oxides are formed or within the more positive range where the surface ...
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 ...
Boron and phosphorus doped glassy carbon: I. Surface properties
(Elsevier, 1997)
The effects of boron and phosphorus incorporation in phenolic resin precursor on the surface properties of glassy carbon (GC) have been studied. Characterization of the surface properties using X-ray photoelectron spectroscopy ...
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 ...
