In- and ex-situ studies of the formation of hydrozinicte (IF = 5.382 (2009), 1. quartile)

In-and ex-situ studies of the formation of layered microspherical hydrozincite as precursor for ZnO. This paper used a combination of in-situ SAXS method and ex-situ electron microscopy (SEM and TEM) and the partial charge model to determine the growth of ZnO particles and NHC. We found that there has been growth mechanism of ZnO particles and the ZnHC (nonclassical concept ) especially and that crystallization takes place by connecting nano building units (5-10 nm) into larger ordered crystalline microstructures and to a lesser extent, there is also a classic growth through diffusion of ions.

Detailed characterization of the defect presented in the ZnO hexagonal rod-like particles (IF = 4.162 (2009), 1. quartile)

ZnO particles, formed by a solution-phase preparation method, have joint microstructure, consisting of two identical hexagonal parts. Until now a concrete analysis of defect has not yet been made. A detailed characterization of the planar base-plane and prismatic defects obtained in the hexagonal ZnO bipod particles with electron microscopy revealed that in the middle of the bipod the planar defects contain a small amount of silicon. We found that these planar defects were inversion domain boundaries with a head-to-head orientation.

The effect of silsesquioxanes on spectrally selective paint coatings with self-cleaning properties (IF = 3.858 (2009), 1. quartile)

Thickness Insensitive Spectrally Selective (TISS) coatings were made of fluoropolymers. Water- and oil-repellent properties (water=150°, n-hexadecane=55°) were improved with the addition of silsesquioxane (AP2IO4PF2 POSS), havind amino (AP), isooctyl (IO) and perfluoro (PF) groups attached on the silsesquioxane (–SiO3/2)8 core. Black spinel pigment was modified with trisilanolisobutyl (IB7T7(OH)3) POSS dispersant that had better influence than isobutyltrimethoxysilane. The surfaces exhibited bi-hierarchical roughness and water sliding angle (10°. POSS also enhanced spectral selectivity.

Colorimetric properties of reversible thermochromic printing inks (IF = 2.855 (2009), 1. quartile)

The screen-printed thermochromic inks were analysed. Their pigments are microencapsulated self-consistent thermochromic composites. Such systems show some sort of memory, evident by colour hysteresis. By analysing these loops, short-term reversibility was evaluated. It is the first study of these phenomena in the world. It was published in the leading journal of the corresponding research area.

Photocatalytic degradation of cholesterol-lowering statin drugs by TiO2-based catalyst (IF = 2.553 (2009), 2. quartile)

Photocatalytic degradation of simvastatin, lovastatin, and pravastatin by TiO2-based catalyst in aqueous solutions was studied. In all cases the degradation was found to be efficient. When present in their open forms, the life times were evaluated, in aerated conditions, to 8.1+-1.2, 10.4+-1.3 and 19.2+-2.1 minutes for simvastatin, lovastatin and pravastatin respectively. Several primary and secondary photoproducts were elucidated by means of LC-MS technique. Under prolonged irradiation efficient mineralization of statin solutions was observed by means of total organic carbon (TOC) evolution.
