Integer codes correcting burst asymmetric within a byte and double asymmetric errors
This paper presents a class of integer codes capable of correcting l-bit burst asymmetric errors within a b-bit byte (1 ≤ l < b) and double asymmetric errors within a codeword. The presented codes are constructed with the ...
The gadolinium effect on crystallization behavior and luminescence of β-NaYF4:Yb,Er phase
Single phase β-NaY0.8-xGdxYb0.18Er0.02F4 nanoparticles with different concentrations of gadolinium ions were prepared via PVP-assisted solvothermal treating at 200°C (PVP- polyvinylpyrrolidone). With the increase in Gd3+ ...
Mg/Cu co-substituted hydroxyapatite – Biocompatibility, mechanical properties and antimicrobial activity
The aim of this study was to improve the mechanical properties and to optimize antimicrobial activity of hydroxyapatite (HAP) by simultaneous doping with Mg and Cu ions in order to obtain material that would be able to ...
Nanocomposite Zn2SnO4/SnO2 Thick Films as a Humidity Sensing Material
Nanocomposite Zn2SnO4/SnO2 powder was obtained by solid state synthesis from homogenized starting nanopowders of ZnO and SnO2, mixed in the 1:1 molar ratio, structurally and morphologically characterized using X-ray ...
Effects of different polymers and solvents on crystallization of theNaYF4:Yb/Er phase
Up-converting NaYF4:Yb,Er nanoparticles were obtained by polymer-assisted solvothermal synthesis using a common solution of hydrated RE nitrates in ethanol or ethylene glycol. It was shown that polymer choice (polyacrylic ...
