Removal of Nickel Ions from Aqueous Solutions by 2-Hydroxyethyl Acrylate/Itaconic Acid Hydrogels Optimized with Response Surface Methodology
(Gels, 2021)
The adsorption of Ni2+ ions from water solutions by using hydrogels based on 2-hydroxyethyl acrylate (HEA) and itaconic acid (IA) was studied. Hydrogel synthesis was optimized with response surface methodology (RSM). The ...
Characterization of potential probiotic strain, L. reuteri B2, and its microencapsulation using alginate-based biopolymers
(International Journal of Biological Macromolecules, 2021)
In this study, Lactobacillus reuteri B2 was isolated from the feces of C57BL/6 mice and assessed on probiotic activity. L. reuteri B2 was identified by 16S rDNA sequencing, which the cell viability in acidic conditions at ...
The chitosan-based bioactive composite coating on titanium
(Elsevier B.V., 2021)
This paper describes a promising electrophoretic deposition (EPD) approach for developing composite coatings based on chitosan with the additional components of hydroxyapatite, graphene, and gentamicin on titanium substrate. ...
Experimental and numerical research on the failure of railway vehicles coupling links
(Engineering Failure Analysis, 2021)
Two modes of failure are analysed for coupling links, the mechanical connections that transmit traction forces between vehicles along the length of a train. Coupling links are designed to withstand the dynamic loads in ...
Sinigrin Encapsulation in Liposomes: Influence on In Vitro Digestion and Antioxidant Potential
(Polish Journal of Food and Nutrition Sciences, 2021)
Encapsulation of sinigrin in liposomes with the proliposomal method was performed in order to evaluate the effect of this process on in vitro simulated digestion and antioxidant potential of sinigrin. The recovery of ...
The chicken eggshell calcium oxide ultrasonically dispersed over lignite coal fly ash-based cancrinite zeolite support as a catalyst for biodiesel production
(Fuel, 2021)
Lignite coal fly ash (FA) from a domestic thermal power plant was converted into a pure cancrinite zeolitic material (ZM(FA)) using a novel, custom-made, rotating autoclave reactor system by a short-term alkali activation ...
Antimicrobial and biological effects of polyaniline/polyvinylpyrrolidone nanocomposites loaded with silver nanospheres/triangles
(New Journal of Chemistry, 2021)
Two silver-polyaniline/polyvinylpyrrolidone (Ag-PANI/PVP) nanocomposites were prepared using in situ integration of silver nanoparticles (AgNPs) during oxidative aniline polymerization, accelerated by the presence of PVP, ...
Implementation of the Chicot-Lesage Composite Hardness Model in a Determination of Absolute Hardness of Copper Coatings Obtained by the Electrodeposition Processes
(Metals, 2021)
The influence of various electrolysis parameters, such as the type of cathode, composition of the electrolyte and electrolysis time, on the morphology, structure and hardness of copper coatings has been investigated. ...
Synthesis and Characterization of Azido Esters as Green Energetic Plasticizers
(Propellants Explosives Pyrotechnics, 2021)
Three azido-esters based green energetic plasticizers were synthesized from their chlorides including DEGBAA (diethyleneglycol bis(azidoacetate)), DPGBAA (dipropyleneglycol bis(azidoacetate)) and HETTAA (hexanetriol ...
An analysis of impact testing of high strength low-alloy steels used in ship construction
(Brodogradnja, 2021)
Brittle damages have been examined widely since welding became common practice when it comes to carrying out robust structures. Welded structure of the ship hull has to be continuous. Brittle damages that occur on hull ...
