The gadolinium effect on crystallization behavior and luminescence of β-NaYF4:Yb,Er phase
(Wiley, 2020)
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+ ...
The influence of alumino-silicate matrix composition on surface hydrophobic properties
(Belgrade : ETRAN, 2019)
The purpose of this investigation is to investigate the hydrophobicity of geopolymers, new alumino-silicate materials and the influence of Si/Al ratio on their surface properties. Contact angle measurement (CAM) as reliable ...
Analysis of Intrinsic Stochastic Fluctuations of the Time Response of Adsorption-Based Microfluidic Bio/Chemical Sensors: the Case of Bianalyte Mixtures
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Real-time in situ operation of bio/chemical sensors assumes detection of chemical substances or biological specimens in samples of complex composition. Since sensor selectivity cannot be ideal, adsorption of particles other ...

Improvement of novel materials could be very good development base for enhancement of new technologies. One of the most promising material of modern science is undoubtedly synthesized diamond. Because of variety of modern ...
BaTiO3-ceramics and grain growth engineering using fractal nature approach
(Societa ceramica italianaPolitecnico di Torino, 2019)
Grain size and morphology of BaTiO3-ceramics are very important characteristics in developing new dielectric devices. Samples with different additives were sintered at different temperatures and times. The microstructure ...
Influence of mechanical activation on kinetics and formation of spinel monitored by DTA
(Central and Eastern European Committee for Thermal Analysis and Calorimetry, 2019)
Magnesium aluminate and other alumina-based spinels are refractory ceramics with excellent properties, such as high hardness, high mechanical strength, and low dielectric constant, applicable in many modern industries. ...
Novel fractal analysis of nanograin growth in BaTiO3 thin film
(Elsevier, 2020)
The grain size and the ferroelectric morphology are the two most important factors in the research and development of advanced dielectric devices. It is important to synthesize nanostructures in order to achieve optimal ...
Relationship between the properties of an interlayer formed by in situ Ti anodization and anaphoretically deposited hydroxyapatite
(Serbian Chemical Society, 2019)
The optimization of the anodization process of Ti substrate for in situ synthesis of hydroxyapatite/titanium oxide composite coatings on titanium substrate was accomplished. The anodization was performed under 30, 60 and ...
