Corrosion Stability and Bioactivity in Simulated Body Fluid of Silver/Hydroxyapatite and Silver/Hydroxyapatite/Lignin Coatings on Titanium Obtained by Electrophoretic Deposition
(Amer Chemical Soc, Washington, 2013)
Hydroxyapatite is the most suitable biocompatible material for bone implant coatings. However, its brittleness is a major obstacle, and that is why, recently, research focused on creating composites with various biopolymers. ...
Rapid cationic dye adsorption on polyphenol-extracted coffee grounds-A response surface methodology approach
(Elsevier Science Bv, Amsterdam, 2014)
The Box-Behnken design under the response surface methodology (RSM) with five interacting parameters (adsorbent dose, initial dye concentration, time of agitation, initial solution pH and time of the adsorbent microwave ...
Microwave-assisted extraction for the recovery of antioxidants from waste Equisetum arvense
(Elsevier, Amsterdam, 2014)
Microwave-assisted extraction was optimised by the response surface methodology in order to enhance the extraction of polyphenols from Equisetum arvense (horsetail). Under the optimal conditions the total polyphenol content ...
In situ generation of Ag nanoparticles on polyester fabrics by photoreduction using TiO2 nanoparticles
(Springer, New York, 2013)
This study discusses the possibility of in situ generation of Ag nanoparticles on polyester fabric by photoreduction of Ag+ ions with deposited TiO2 nanoparticles in the presence of amino acid alanine and methyl alcohol. ...
Isopiestic determination of the osmotic and activity coefficients of the {yK(2)SO(4) + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2014)
The molality-based osmotic coefficients of aqueous mixtures of K2SO4 and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic method, at K2SO4 ionic strength fractions y = (0.21008, 0.39887, 0.60657, ...
Improved beta-amylase production on molasses and sugar beet pulp by a novel strain Paenibacillus chitinolyticus CKS1
(Elsevier, Amsterdam, 2016)
Molasses and sugar beet pulp, by-products in sugar industry, are produced in large amounts annually which create disposal problems. High sugar content in sugar beet molasses enables its use for fermentations while sugar ...
Biological potential of puffballs: A comparative analysis
(Elsevier, Amsterdam, 2016)
Handkea utriformis (HU), H. excipuliformis (HE) and Vascellum pratense (VP) mature fruiting bodies methanol extracts were tested for biological activities and active compounds. The extracts showed prominent radical scavenging, ...
Degradation of beech wood and wheat straw by Trametes gibbosa
(Springer, New York, 2017)
The aim of this study was to optimize cultivation conditions for Mn-oxidizing peroxidases and laccase production and selective degradation of beech wood and wheat straw lignin by Trametes gibbosa. To promote lignin ...
Abnormalities in the ovule development of the European plum cultivar 'Pozna Plava' in the days following anthesis
(Elsevier Science Bv, Amsterdam, 2019)
Factors such as the stage of ovule maturity and longevity at flowering, when the stigma is able to receive the pollen, are significant in terms of fruit set. Various abnormalities during ovule development can often limit ...
Removal of model cationic dye by adsorption onto poly(methacrylic acid)/zeolite hydrogel composites: Kinetics, equilibrium study and image analysis
(Elsevier, Amsterdam, 2014)
Composites based on poly(methacrylic acid) (PMAA) and two types of zeolite, hydrophilic zeolite A and hydrophobic zeolite ZSM-5, were synthesized. The obtained hydrogel composites that combine well the strong interaction ...
