Valorization of walnut shell ash as a catalyst for biodiesel production
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The catalytic activity of the walnut shell ash was investigated in the biodiesel production by the sunflower oil methanolysis. The catalyst was characterized by the TG-DTA, XRD, Hg porosimetry, Ny physisorption, SEM, and ...
Corrosion of stainless steel 316Ti tank for the transport 12-15% of hypochlorite solution
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The corrosion of the transport tank materials made of stainless steel 316Ti is investigated in a solution containing 12-15% of the commercial sodium hypochlorite solution. Using the electrochemical techniques, weight loss ...
A Three-electrode gas arrester for low voltage isolation coordination
(Elsevier Sci Ltd, Oxford, 2020)
This work aims is to design, fabricate and test a gas surge arrester with optimum characteristics based on testing the influence of all parameters that affect the characteristics of gas surge arresters for the coordination ...
Sintering, crystallization and foaming of La2O3 center dot SrO center dot 5B(2)O(3) glass powders: effect of the holding time
(Elsevier, Amsterdam, 2020)
Sintering, crystallization and foaming of nano glass powders with composition La2O3 center dot SrO center dot 5B(2)O(3) were studied by hot stage microscopy (HSM) and simultaneous thermal analysis (DTA-TG) under non-isothermal ...
A detailed experimental and computational study of monocarbohydrazones
(Elsevier, Amsterdam, 2020)
The substituent and solvent effect on intramolecular charge transfer (ICT) of twelve monocarbohydrazones (mCHs) were studied using experimental and theoretical methodology. The effects of specific and non-specific ...
Selenate Adsorption from Water Using the Hydrous Iron Oxide-Impregnated Hybrid Polymer
(Metals, 2020)
Hybrid adsorbent, based on the cross-linked copolymer impregnated with hydrous iron oxide, was applied for the first time for Se(VI) adsorption from water. The influence of the initial solution pH, selenate concentration ...
Considerations for the design and conduct of human gut microbiota intervention studies relating to foods
(Springer Heidelberg, Heidelberg, 2020)
With the growing appreciation for the influence of the intestinal microbiota on human health, there is increasing motivation to design and refine interventions to promote favorable shifts in the microbiota and their ...
Amides as a model system of low molar mass algal organic matter. Influence on the adsorption of p-nitrophenol on activated carbon
(Elsevier, Amsterdam, 2020)
In this study, the adsorption equilibrium and diffusivity parameters of p-nitrophenol were estimated for water containing different concentrations of secondary amides. Commercial powdered activated carbon was used as an ...
