The influence of the surface nanostructured modification on the corrosion resistance of the ultrafine-grained Ti-13Nb-13Zr alloy in artificial saliva
(Elsevier, Amsterdam, 2019)
On the surface of the ultrafine-grained Ti-13Nb-13Zr alloy and the coarse-grained Ti-13Nb-13Zr alloy nanotubular oxide layers were formed by electrochemical anodization in the 1 M H3PO4 + NaF electrolyte in order to evaluate ...
Tensile and Corrosion Properties of Anodized Ultrafine-Grained Ti-13Nb-13Zr Biomedical Alloy Obtained by High-Pressure Torsion
(Korean Inst Metals Materials, Seoul, 2021)
Severe plastic deformation (SPD) is a popular group of techniques applied to achieve the nanostructuring of the metallic biomaterials and improvement of their mechanical characteristics. One of the most commonly used SPD ...
Highly efficient enzymatic acetylation of flavonoids: Development of solvent-free process and kinetic evaluation
(Elsevier Science Bv, Amsterdam, 2017)
Solubility and stability of flavonoid glycosides, valuable natural constituents of cosmetics and pharmaceuticals, could be improved by lipase-catalyzed acylation. Focus of this study was on development of eco-friendly ...
Study on the pyrolysis products of two different hardwood lignins in the presence of NiO contained-zeolites
(Elsevier Ltd, 2017)
Several NiO contained-zeolites (NiO/H-ZSM-5, NiO/H-BETA and NiO/H-Y) prepared by a mechanochemical dry milling (MCDM) were tested in the pyrolysis of two hardwood lignins: Eucalyptus (EUC) and a mixture of birch and aspen ...

Fracture assessment of seam and seamless steel pipes by application of the ring-shaped bending specimens
(Elsevier, Amsterdam, 2019)
The topic of this work is analysis of fracture behaviour and resistance of the thin-walled seamless and seam steel pipes, through application of the recently proposed ring-shaped specimen (PRNB - Pipe Ring Notched Bend). ...
Epoxy-silanization - tool for improvement of silica nanoparticles as support for lipase immobilization with respect to esterification activity
(Wiley, Hoboken, 2016)
BACKGROUND: In this study, in order to obtain the best support for the immobilization of lipase from Candida rugosa (CRL), the procedure for chemical modification of fumed silica nanoparticles (FNS) with (3-Glycidyloxypropyl) ...
Silver/Poly(N-vinyl-2-pyrrolidone) Hydrogel Nanocomposites Obtained by Electrochemical Synthesis of Silver Nanoparticles Inside the Polymer Hydrogel Aimed for Biomedical Applications
(Wiley, Hoboken, 2014)
Silver nanoparticles were produced inside a poly(N-vinyl-2-pyrrolidone) hydrogel (PVP) by an innovative method based on the electrochemical reduction of Ag+ ions within the swollen PVP hydrogel. UV-visible spectroscopy ...
Synthesis of pure and La-doped anatase nanopowders by sol-gel and hydrothermal methods and their efficiency in photocatalytic degradation of alprazolam
(Elsevier Ltd., 2014)
Pure and La3+ doped titanium dioxide (TiO2) nanopowders were obtained by sol gel and hydrothermal methods. A precursor was titanium tetrachloride and concentrations of dopants were 0.5 and 1.0 mol%. Procedures of both ...
Novel protein-repellent and antimicrobial polysaccharide multilayer thin films
(Walter de Gruyter Gmbh, Berlin, 2019)
Nanostructured and bio-active polysaccharide-based thin films were manufactured by means of subsequent spin-coated deposition of a regenerated cellulose (RC) layer and a 2,2,6,6-Tetramethylpiperidine-1-oxyl radical (TEMPO) ...
