Influence of picosecond laser pulses on the microstructure of austenitic materials
(Springer, New York, 2011)
We investigate samples of austenitic materials - stainless steel and iron-based superalloy - which are widely used at high temperatures and pressures. The samples were exposed to Nd(3+):YAG laser pulses with a wavelength ...
Short-circuit oxygen diffusion in thermally grown silica layer
(World Scientific Publ Co Pte Ltd, Singapore, 2010)
Amorphous polymer-derived Si-C-N ceramics can be doped with different elements (Al, B etc.) through various pre-ceramic polymer routes. Thus, controlling of the high temperature oxidation resistance can be achieved on an ...
Green pH- and magnetic-responsive hybrid hydrogels based on poly(methacrylic acid) and Eucalyptus wood nanocellulose for controlled release of ibuprofen
(Cellulose, 2021)
pH- and magnetic-sensitive hybrid hydrogels based on poly(methacrylic acid) (PMAA), nanocellulose (NC), carboxymethyl cellulose (CMC) and magnetite particles (MN) were prepared as ibuprofen delivery system. NC was isolated ...
Surface structural heterogeneity of high power plasma-sprayed hydroxyapatite coatings
(Elsevier Science Sa, Lausanne, 2016)
The aim of this work was to examine the dependence of the local surface structure (surface structural heterogeneity) on the local thickness (thickness uniformity) and structure properties along the thickness of hydroxyapatite ...
Modification of PET and PA fabrics with alginate and copper oxides nanoparticles
(Composite Interfaces, 2021)
The aim of this study was to fabricate novel antimicrobial nanocomposite materials by in-situ syntheses of Cu-based nanoparticles on PET and PA fabrics. The synthesis comprised three steps: (i) modification of PET and PA ...
Tio2/zro2 thin films synthesized by pld in low pressure n-, c- and/or o-containing gases: structural, optical and photocatalytic properties
(Inst Materials Physics, Bucharest, 2012)
Doped TiO2/ZrO2 films were obtained by Pulsed Laser Deposition method under different synthesis conditions. The onset of absorption spectra was red shifted for the films obtained in N-2 containing gas mixtures, while a ...
Isopiestic determination of the osmotic and activity coefficients of the {yKNO(3) + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2012)
The osmotic coefficients of aqueous mixtures of KNO3 and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method at KNO3 ionic strength fractions y = (0.20581, 0.43631, 0.61099, and ...
Influence of the gelation and calcination temperatures on physical parameters and photocatalytic activity of mesoporous titania powders synthesized by the nonhydrolytic sol-gel process
(Elsevier, Amsterdam, 2012)
Titania powders were synthesized by nonhydrolitic sol-gel process starting from titanium(IV)-chloride, titanium(IV)-isopropoxide and carbon-tetrachloride. Gelation was performed in solvothermal conditions, at 140 degrees ...
Effect of neutralization degree of methacrylic acid on hydrogel swelling and drug release
(the Faculty of Technology, University of Banja Luka, 2022)
Drug delivery system is an amazing tool which is widely used for drug
protection and its controlled release in order to enhance drug bioavailability,
reduce side effects and therefore to improve overall therapy. Hydrogels ...
Nanocomposite microfibers based on alginate and PVA hydrogels with incorporated silver nanoparticles
