In the spirit of the sustainable buildings, and with the goal of protection of river courses, in the near future an already announced directive ordering closing down of a large number of river aggregate dredging operations ...

Zinc oxide is one of the most studied materials due to its wide bandgap (3.37 eV) and large exciton binding energy (60 meV) which enables application in electronics, optoelectronics and spintronics. In the forms of single ...

Processing of hybrid composites represents a challenge for engineers where the aim is to establish compatibility among several materials. The aim of this study is to evaluate the effects of different sizes and morphologies ...

Nano-sized titanium monoxide (TiO) powder was prepared by mechanochemical synthesis. A mixture of commercial Ti and TiO2 (rutile) powders with the molar ratio of 1:1 was milled in a planetary ball mill for 5, 10, 20, 30 ...

Ceramics grains contacts are essential for understanding complex dielectric properties of electronic ceramics materials. Since the actual contact surface is an irregular object, the theory of fractal sets is applied. Also, ...

In this work, the polycrystalline samples Y1-xYbxF3 (x = 0.01, 0.05, 0.1, 0.25, 0.5, 0.75 and 1) were synthesized and characterized by X-ray powder diffraction and magnetic measurements. In the first stage of synthesis, ...

Specific group of controlled drug delivery systems in bone tissue engineering are multifunctional nanoparticle systems (MNPs) based on hydroxyapatite coated with drug loadedbioresorbable polymer. This study illustrates the ...

A single crystal Bi0.9Sb0.1 ingot was synthesized using the Bridgman technique. Thermal diffusivity and electronic transport properties of single crystal cleaved plates (00l) were determined from PA photoacoustic phase and ...

Fig. S1. TEM (a) and HRTEM (b) images of amino modified NaYF4:Yb,Er UCNPs. Corresponding FFT/IFFT given as insets in b, confirms that much smaller crystallites notable at the particles surfaces (a) revealed periodic array ...
