Synthesis and characterization of fully bio-based unsaturated polyester resins
(Springer, New York, 2018)
The sustainable tomorrow for future generations lies with the present industrial development toward the proper utilization of various bio-based products. For a transition to a higher level of sustainability, it is necessary ...
Functionalization of polypropylene, polyamide and cellulose acetate materials with pyrethrum extract as a natural repellent in supercritical carbon dioxide
(Elsevier Science Bv, Amsterdam, 2018)
This study discusses the possibility of supercritical solvent impregnation of polypropylene and polyamide fabrics as well as cellulose acetate in the form of beads and films with pyrethrum extract in order to fabricate ...
Fractal approach to ac impedance spectroscopy studies of ceramic materials
(Kluwer Academic Publ, Dordrecht, 2001)
A novel fractal model for grain boundary regions of ceramic materials was developed. The model considers laterally inhomogeneous distribution of charge carriers in the vicinity of grain boundaries as the main cause of the ...
Microstructure and cavitation erosion performance of nickel-Inconel 718 composite coatings produced with cold spray
(Elsevier Science Sa, Lausanne, 2020)
The cold spray technique was employed in this study to produce pure nickel (Ni) and nickel-Inconel 718 powder deposits on duplex stainless steel substrates. High quality coatings were manufactured using nitrogen as the ...
Broad Spectrum of Antimicrobial Activity of Cotton Fabric Modified with Oxalic Acid and CuO/Cu2O Nanoparticles
(Korean Fiber Soc, Seoul, 2019)
This study discusses the possibility of fabrication of textile nanocomposites with antimicrobial activity against antibiotics-resistant bacterial strains and yeast. Modification of cotton fabric with oxalic acid solutions ...
Chitosan-based hydrogel wound dressings with electrochemically incorporated silver nanoparticles - In vitro study
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this work, we provide a facile path for the preparation of wound dressing materials with improved characteristics based on biocompatible chitosan and poly(vinyl alcohol) hydrogels with embedded silver nanoparticles ...
Morphology, Structure and Mechanical Properties of Copper Coatings Electrodeposited by Pulsating Current (PC) Regime on Si(111)
(MDPI, Basel, 2020)
Copper electrodeposition on (111)-oriented Si substrate was performed by the pulsating current (PC) regime at various average current densities in the range of 15-70 mAcm(-2), obtained by varying either the frequency (30, ...
Hemp-based adsorbents for sequestration of metals: a review
(Springer Heidelberg, Heidelberg, 2019)
With the increasing focus on renewable materials and sustainability issues, the development of non-conventional materials from natural resources and possessing complexing properties is currently an area of extensive research ...
Plant growth-promoting bacteria elevate the nutritional and functional properties of black cumin and flaxseed fixed oil
(Wiley, Hoboken, 2018)
BACKGROUNDIn order to study the influence of plant growth-promoting bacteria (PGPB) belonging to Streptomyces sp., Paenibacillus sp., and Hymenobacter sp. on fixed oil content of flaxseed and black cumin, 2-year field ...
The relation between the high speed submerged cavitating jet behaviour and the cavitation erosion process
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
In order to accurately and reliably evaluate the cavitation erosion resistance of materials using a cavitating jet generator, the effects of the hydrodynamic parameters and the nozzle geometry on the erosion process were ...
