A CaO/zeolite-based catalyst obtained from waste chicken eggshell and coal fly ash for biodiesel production
(Elsevier Sci Ltd, Oxford, 2020)
The present paper is focused on the development of a new environment-friendly methanolysis catalyst completely based on waste materials: lignite coal fly ash and chicken eggshells. A novel catalyst based on CaO supported ...
Growth control of molds isolated from smoked fermented sausages using basil and caraway essential oils, in vitro and in vivo
(Elsevier, Amsterdam, 2020)
Food contamination by molds is a serious issue in food industry still today. On the other hand, consumers today demand food that is minimally processed and without synthetic preservatives and additives. Therefore, the ...
Reactor conceptual design by optimization for hydrogen production through intensified sorption- and membrane-enhanced water-gas shift reaction
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
In this feasibility study, a novel industrial-scale reactor structure for continuous hydrogen production via intensified water-gas shift (WGS) reaction is proposed. It considers both trickling calcium-oxide sorbent for ...
Isopiestic Determination of Osmotic and Activity Coefficients of the {yNaH(2)PO(4) + (1-y)Na2HPO4}(aq) System at T=298.15 K
(Journal of Chemical and Engineering Data, 2020)
Isopiestic measurements have been made for aqueous solutions of the common sodium cation mixtures of NaH2PO4 and Na2HPO4 at T = 298.15 +/- 0.01 K, at NaH2PO4 ionic strength fractions y = (0, 0.24851, 0.49862, 0.74544, and ...
Oxidative degradation of Acid Blue 111 by electro-assisted Fenton process
(Elsevier, Amsterdam, 2020)
The degradation of Acid Blue 111 anthraquinone dye has been studied by the simple electro-assisted Fenton process and the obtained results were compared to the Fenton process. Ferrous sulphate and hydrogen peroxide were ...
Numerical determination and experimental validation of the fracture toughness of welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Most of the serious weldment failures lead to catastrophic consequences in terms of damage of other equipment, loss of production, and risks to workers' health and safety. Hence, there is motivation to find margin between ...
Isopiestic determination of the osmotic and activity coefficients of {yK(2)HPO(4) + (1-y)KH2PO4}(aq) at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2020)
Isopiestic measurements have been made at 55 compositions of the {yK(2)HPO(4) + (1 - y)KH2PO4}(aq) system at T = (298.15 +/- 0.01) K, 11 for each of the limiting binary solutions and 33 for mixture compositions at K2HPO4 ...
Improvement of lignocellulosic biomass conversion by optimization of fungal ligninolytic enzyme activity and molasses stillage supplementation
(Springer Heidelberg, Heidelberg, 2022)
Fungal treatment of lignocellulose is an ecologically and economically acceptable method. However, it needs improvement to increase the hydrolysis rate. A novel combination of multiple response optimization of ligninolytic ...
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 ...
Use of carbon paste electrode and modified by gold nanoparticles for selected macrolide antibiotics determination as standard and in pharmaceutical preparations
(Elsevier B.V., 2020)
In this work, carbon paste electrode (CPE) and carbon paste electrode modified with gold nanoparticics (AuNPs/CPE) were employed with rapid direct anodic square wave voltammetry (SWV) for macrolide antibiotics erythromycin ...
