Essential oil of anthemis carpatica
(Taylor & Francis, 1997)
The essential oil obtained from air-dried aerial parts of plant species Anthemis carpatica Willd. (Asteraceae), was analyzed by GC and GC/MS, and about 50 components were identified. The major constituents, α-thujone ...
Essential oil of achillea corabensis (heimerl) micevski
(Taylor & Francis, 1997)
The essential oil of Achillea corabensis (Heimerl) Micevski collected from a natural location as well as from plants cultivated in the Sirinic valley of Sara mountain was analyzed. In the oil of collected plants 41 compounds ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
