Phonon spectra of Cd1-xMnxS (x = 0; 0.01; 0.05; 0.1; 0.15; 0.3) nanoparticles (d similar to 4.5 rim) have been investigated by far-infrared reflection (FIR) (spectral range 40 - 600 cm(-1), temperature range 80-300 K) and ...

In this paper we used X-ray, far-infrared reflectivity and electron paramagnetic resonance measurements to investigate the optical and magnetic properties of Hg1-xMnxSe (x LT = 0.26) alloys. Also, we used different models ...

Zn this work we used far-infrared and Raman spectroscopy for investigation of gallium doping influence on optical and transport properties of PbTe. We focused our interest to fortify the correlation between local modes and ...

X-ray fluorescence and DTA-specific heat measurements were performed on several samples of the Hf-Fe phase system, at 50:50%, and 33:67% concentrations. In the first concentration range the possibility of an ordered compound ...

Phonon spectra of Cd1-xMnxS (x =0; 0.01; 0.05; 0.1; 0.15; 0.3) quantum dots (dsimilar to4.5 nm) are investigated by far-infrared reflection in the spectral range 80 - 600 cm(-1) and temperature range 80-300 K. The Cd1-xMnxS ...

Using semi-empirical quantum mechanic (AMI, ZINDO/S) and ab-initio Hartree-Fock (HF) calculations we investigated selected structural, electronic and vibrational properties of phenylene-based oligomers from biphenyl P2P ...

SiO2 layers were deposited by reactive d.c ion sputtering (using 1 keV Ar+ ion gun) from a high purity silicon target in an oxygen ambient. The base pressure in the deposition chamber was 4.7-10(-9) mbar, and the substrate ...

The influence of the aging time of RuO2 sol on the electrochemical properties and behaviour in chlorine evolution reaction of RuO2/Ti and (40%RuO2 + 60%TiO2)/Ti anodes obtained by sol-gel procedure was studied. The ...
