(Amer Chemical Soc, Washington, 2020)
Isopiestic measurements have been made for aqueous solutions of the common sodium cation mixtures of NaH2PO4and Na2HPO4at T = 298.15 ± 0.01 K, at NaH2PO4ionic strength fractions y = (0, 0.24851, 0.49862, 0.74544, and 1), ...
Novel amino-functionalized lignin microspheres: High performance biosorbent with enhanced capacity for heavy metal ion removal
(Elsevier, Amsterdam, 2020)
Novel highly effective amino-functionalized lignin-based biosorbent in the microsphere geometry (A-LMS) for removal of heavy metal ions, was synthesized via inverse suspension copolymerization of kraft lignin with poly(ethylene ...
Kinetics of sunflower oil methanolysis catalyzed by calcium oxide
(Elsevier, 2009)
The methanolysis of sunflower oil was studied in the presence of CaO previously calcined at various temperatures and the optimal temperature for CaO calcination was determined. The sigmoidal process kinetics was explained ...
First principle calculations of alkali hydride electronic structures
(Journal of Physics: Condensed Matter, 2007)
Electronic structure, volume optimization, bulk moduli, elastic constants, and frequencies of the transversal optical vibrations in LiH, NaH, KH, RbH, and CsH are calculated using the full potential augmented plane wave ...
Semi-interpenetrating networks based on (Meth)acrylate, itaconic acid, and poly(vinyl pyrrolidone) hydrogels for biomedical applications
(Springer Singapore, 2020)
In this study, three series of semi-interpenetrating networks were synthesized based on 2-hydroxyethyl methacrylate (HEMA), 2-hydroxyethyl acrylate (HEA), itaconic acid (IA), and poly(vinyl pyrrolidone) (PVP) as interpenetrating ...
Nonlinear optical effects in asymmetric AlGaAs/GaAs semiconductor quantum wells
(Trans Tech-Scitec Publications Ltd, Durnten-Zurich, 1998)
Optical nonlinearities in three-level asymmetric semiconductor quantum wells (QW) are analyzed (optical rectification, second harmonic generation (SHG)). The influence of permanent dipole moments on SHG conversion efficiency ...
Dietary intake and health risk assessment of essential and toxic elements in pepper (Capsicum annuum)
(Academic Press Inc., 2022)
The content of twenty-one essential and toxic elements in fresh, dried, and processed peppers (Capsicum annuum) obtained from the Serbian market was analyzed. The concentration of the elements varied significantly between ...
Immobilization of Horseradish Peroxidase on Macroporous Glycidyl-Based Copolymers with Different Surface Characteristics for the Removal of Phenol
(Springer, 2022)
Novel macroporous copolymers of glycidyl methacrylate and ethylene glycol dimethacrylate with mean pore size diameters ranging from 150 to 310 nm were synthesized by dispersion polymerization and modified with ethylenediamine. ...
