Quantitative comparison of iron and cobalt based catalysts for the Fischer-Tropsch synthesis under clean and poisoning conditions
(Elsevier, Amsterdam, 2020)
Quantitative data comparing iron and cobalt based catalysts for the Fischer-Tropsch synthesis (FTS) are scarce due to the fact that these two kinds of catalysts typically utilize different process conditions. This paper ...
Optimization of forced periodic operations in milli-scale fixed bed reactor for Fischer-Tropsch synthesis
(Elsevier, Amsterdam, 2020)
One-dimensional pseudo-homogenous dynamic reactor model, incorporating detailed Fischer-Tropsch kinetics, was applied in a theoretical analysis of forced periodic operations. A milli-scale fixed-bed reactor was analyzed, ...
Application of waste cotton yarn as adsorbent of heavy metal ions from single and mixed solutions
(Springer Heidelberg, Heidelberg, 2020)
In this study, waste cotton yarn was used for the removal of Pb (II), Cd (II), Cr (III), and As (V) from aqueous solution. Adsorption of heavy metal ions was tested from single ion solutions, while competitive studies were ...
Effect of plasma treatment on chemical composition, structure and sorption properties of lignocellulosic hemp fibers (Cannabis sativa L.)
(Elsevier Sci Ltd, Oxford, 2020)
Hemp fibers with different amount of hemicelluloses and lignin were subjected to atmospheric pressure dielectric barrier discharge under different conditions (40 W and 80 W power of discharge, const. time 120 s) in order ...
Polymer composite films and nanofibers doped with core-shell quantum dots
(Natl Inst Optoelectronics, Bucharest-Magurele, 2020)
Processing and characterization of polymer nanocomposites based on poly(methyl methacrylate) (PMMA) matrix with embedded core-shell CdSe/ZnS quantum dots were investigated. Nanocomposites were obtained via solution casting ...
Kinetics and column adsorption study of diclofenac and heavy-metal ions removal by amino-functionalized lignin microspheres
(Elsevier Science Inc, New York, 2021)
In-depth kinetic and column adsorption study for diclofenac, DCF, heavy-metal and oxyanions adsorption on highly effective amino-functionalized lignin-based microsphere adsorbent (A-LMS) is examined. The A-LMS was synthesized ...
Surface-modified ZrO2 nanoparticles with caffeic acid: Characterization and in vitro evaluation of biosafety for placental cells
(Chemico-Biological Interactions, 2021)
The toxicity of hybrid nanoparticles, consisting of non-toxic components, zirconium dioxide nanoparticles (ZrO2 NPs), and caffeic acid (CA), was examined against four different cell lines (HTR-8 SV/Neo, JEG-3, JAR, and ...
Self-Assembly and Biorecognition of a Spirohydantoin Derived from alpha-Tetralone: Interplay between Chirality and Intermolecular Interactions
(Wiley-VCH Verlag, 2020)
A racemic spirohydantoin derivative with two aromatic substituents, a tetralin and a 4-methoxybenzyl unit, was synthesized and its crystal structure was determined. To define the relationship between molecular stereochemistry ...
The influence of coating with aminopropyl triethoxysilane and CuO/Cu2O nanoparticles on antimicrobial activity of cotton fabrics under dark conditions
(Wiley, Hoboken, 2020)
A novel impregnation process for the fabrication of cotton nanocomposite with strong antimicrobial activity against antibiotics-resistant bacteria and yeast was developed. The impregnation process includes the sol-gel ...
Dissimilar sintered calcium phosphate dental inserts as dentine substitutes: Shear bond strength to restorative materials
(Wiley, Hoboken, 2020)
The application of sintered calcium phosphate dental inserts in the central part of tooth cavities can reduce amount of embedded dental composite and polymerization shrinkage of final dental fillings. The aim of this study ...
