Manifestations of dynamic strain ageing in 2090 Al-Li alloy
(International Journal of Materials Research, 2022)
The manifestations of dynamic strain ageing in a commercial 2090 Al - Li alloy were investigated in a wide range of temperatures (-40 to 100 degrees C) and strain rates (4.16x10(-5) to 4.16x10(-3) s(-1) ). Serrated yielding, ...
Analysis of the Ce(III) chloride, Ce(III) nitrate, and Ce(III) propionate as corrosion inhibitor of the aluminum alloys in NaCl solution
(John Wiley and Sons Inc, 2022)
Green corrosion inhibitors, Ce(III) chloride, Ce(III) nitrate, and Ce(III) propionate, were tested in NaCl solution with the aim to evaluate their inhibitory effect on 7049 aluminum alloy and to propose a mechanism of their ...
Extraction of lyophilized olive mill wastewater using supercritical CO2 processes
(Alexandria Engineering Journal, 2022)
The olive growing in Tunisia has an economic dominance and agricultural importance. However, the huge extraction of olive oil generates a large quantity of olive mill wastewater (OMW), which is discharged to the surroundings. ...
Use of chènevotte, a valuable co-product of industrial hemp fiber, as adsorbent for copper ions: Kinetic studies and modeling
(Elsevier B.V., 2022)
In this study, a series of hemp shives (chènevotte) with different chemical compositions and properties, namely a raw (SHI-R), a washed with water (SHI-W), three samples chemically modified with KOH (SHI-OH), Na2CO3 (SHI-C) ...
Optimization of Pretreatment Conditions and Enzymatic Hydrolysis of Corn Cobs for Production of Microbial Lipids by Trichosporon oleaginosus
(MDPI, 2022)
Microbial lipids produced from lignocellulosic biomass are sustainable alternative feedstock for biodiesel production. In this study, corn cobs were used as a carbon source for lipid production and growth of oleaginous ...
Modulated interference effect by ZnS nanoparticles / 3-Mercaptopropyltrimethoxysilane quasi core-shell structure: Far-infrared spectroscopy
(National Institute of Optoelectronics, 2022)
The ZnS nanoparticles, as starting materials in the present study, were synthesized mechanochemically. Surface modification of the obtained nanoparticles was performed by 3-Mercaptopropyltrimethoxysilane. SEM analysis ...
Gravimetric and instrumental methods comparison for experimental determination of carbonate carbon content in solid mineral fuels
(Thermal Science, 2022)
The content of combustible elements in solid mineral fuels (carbon, hydrogen, etc.) are very important, since they most directly affect the heat value. It should be noted that the fuel heat value depends on many other ...
Examination and optimization of lignocellulolytic activity of Stereum gausapatum F28 on beechwood sawdust supplemented with molasses stillage
(Journal of the Serbian Chemical Society, 2022)
This study provides a detailed analysis of the lignocellulolytic activity of a new isolate Stereum gausapatum F28, a Serbian autochthonous fungi, on beechwood sawdust supplemented with cheap waste, sugar beet molasses still ...
Transesterification of used cooking sunflower oil catalyzed by hazelnut shell ash
(Renewable Energy, 2022)
Hazelnut shell ash was investigated as a new base catalyst for the transesterification of used cooking sunflower oil to biodiesel. To understand its catalytic properties, the prepared ash was characterized by EDX, XRD, ...
Thermal Design Method for Optimization of Dry Heat Transfer through Hemp-Based Knitted Fabrics
(Taylor and Francis Ltd., 2022)
In the present research, folding of yarns was applied as a method for designing thermal transport characteristics of hemp-based knits. The rib-knitted fabrics were made by combining one of two cotton two-folded yarns ...
