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 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 ...
New Eco-Friendly Xanthate-Based Flotation Agents
(MDPI, Basel, 2020)
An optimal laboratory two-step procedure was developed for sodium/potassium O-alkyl carbonodithioate (sodium/potassium alkyl xanthates) production in the form of aqueous solutions. Sodium isopropyl xanthate (Na-iPrX), as ...
Evaluation of Nisin and LL-37 Antimicrobial Peptides as Tool to Preserve Articular Cartilage Healing in a Septic Environment
(Frontiers Media Sa, Lausanne, 2020)
Cartilage repair still represents a challenge for clinicians and only few effective therapies are nowadays available. In fact, surgery is limited by the tissue poor self-healing capacity while the autologous transplantation ...
Nonlinear frequency response analysis of forced periodic operations with simultaneous modulation of two general waveform inputs with applications on adiabatic CSTR with square-wave modulations
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Nonlinear frequency response (NFR) method was used to evaluate the forced periodic operations and their potential for improving the system performance compared to steady-state operations. The NFR method was used to evaluate ...
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 ...
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 ...
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 ...
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 ...
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 ...
