Effect of YAG content on creep resistance and mechanical properties of Al2O3-YAG composite
(Elsevier Sci Ltd, Oxford, 2020)
Comprehensive study on effect of YAG amount on densification, creep resistance and room-temperature mechanical properties of Al2O3-YAG composite pressureless sintered at 1600 degrees C was conducted. The main goal was to ...
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 ...
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 ...
Surface optical phonon (SOP) mode in ZnS/Poly (methylmethacrylate) nanocomposites
(Elsevier, Amsterdam, 2020)
The polymer nanocomposite ZnS/Poly (methylmethacrylate) was prepared by the solution casting method and its structural and optical properties were investigated using XRD, SEM, TEM, HRTEM, and Raman spectroscopy. The basic ...
Chemical Modifications of Jute Fiber Properties for Lifecycle Enhancement by Utilization in Wastewater Treatment
(New York : Nova Science Publishers, Inc., 2022)
The increased demand for cheap, biodegradable, renewable, and recyclable fibers with exceptional properties positioned jute (Corchorus capsularis L. and Corchorus olitorius L.) in the second place (after cotton) in the ...
On the photophysical properties of a liquid crystal dimer based on 4-nitrostilbene: A combined experimental and theoretical study
(Journal of Molecular Liquids, 2021)
A new liquid crystal dimer, 1,12-bis(4-(2-(4-nitrophenyl)ethenyl)phenoxy)dodecane, was synthesized and structurally characterized. The compound exhibited enantiotropic nematic phase. The spectroscopic properties were ...
Hybrid acrylic nanocomposites with excellent transparency and hardness/toughness balance
(Elsevier B.V., 2020)
The composite nanofibers were used as reinforcement in acrylic polymer for the overall enhancement of thermo-mechanical properties, adhesion between fibers and matrix, and fracture toughness of the final nanocomposite since ...
