Principal component analysis of morphological descriptors for monitoring surface defects induced by thermal shock
(Elsevier Ltd, 2021)
Pattern recognition techniques are applied to various morphological descriptors to monitor the formation and propagation of surface defects of materials subjected to thermal shock. A low-cement high-alumina castable was ...
Effects of selected inorganic chemical activators on properties and hydration mechanism of high volume fly ash (HVFA) binders
(Elsevier Ltd., 2023)
Effects of Na2SO4, Na2CO3, and Na2SiO3 on setting time, compressive strength (up to 90 days), and hydration mechanism of binders with high volume (70 wt%, HVFA binders) of fly ash (FA) were investigated. Before chemical ...
Tautomerism in 8-(phenyldiazenyl)quinolin-5-ol: An attempt for pH activated rotary switch
(Elsevier Sci Ltd, Oxford, 2020)
The tautomerism of 8-(phenyldiazenyl)quinolin-5-ol has been studied by a combination of theoretical (DFT calculations) and experimental (UV-Vis and NMR) methods. The detailed study of neutral molecules has shown that the ...
Stability of TEMPO-oxidized cotton fibers during natural aging
(Elsevier Sci Ltd, Oxford, 2020)
Stability of cotton fibers oxidized by the 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO)-mediated system during natural aging was monitored; the oxidized and five-year-aged fibers were characterized in terms of ...
Batch and column adsorption of cations, oxyanions and dyes on a magnetite modified cellulose-based membrane
(Springer, Dordrecht, 2020)
An optimized method is presented to make magnetite (MG) modified cellulose membrane (Cell-MG) from 3-aminopropyltriethoxysilane and diethylenetriaminepentaacetic acid dianhydride functionalized waste cell fibers; (Cell-NH(2)and ...
Solar-driven thermo-photocatalytic CO2 methanation over a structured RuO2:TiO2/SBA-15 nanocomposite at low temperature
(Elsevier B.V., 2024)
A new hybrid catalyst composed of mesostructured silica SBA-15 functionalized with TiO2 and further loaded with RuO2 was developed to efficiently promote thermo-photocatalytic CO2 hydrogenation into methane at low temperatures. ...
Influence of Potassium Permanganate Oxidation on Structure and Properties of Cotton
(Taylor & Francis Inc, Philadelphia, 2022)
Cotton yarn was oxidized using the various concentrations and pH of potassium permanganate solutions, in order to investigate the influence of oxidation parameters on chemical, mechanical and sorption properties of cotton. ...
Production of prebiotic enriched maple syrup through enzymatic conversion of sucrose into fructo-oligosaccharides
(Elsevier Ltd., 08-2024)
Maple syrup, a popular natural sweetener has a high content of sucrose, whose consumption is linked to different health issues such as obesity and diabetes. Hence, within this paper, the conversion of sucrose to prebiotics ...
Closing the loop: As(V) adsorption onto goethite impregnated coal-combustion fly ash as integral building materials
(Journal of Cleaner Production, 2021)
Fly and bottom ash(es) are the most abundant generated by-products of coal combustion in thermal power plants. This investigation offers a sustainable solution of a double and circular use of industrial waste material in ...
Impedance analysis of milk quality using functionalized polyamide textile-based sensor
(Computers and Electronics in Agriculture, 2021)
Present paper demonstrates design and characterization of a textile based microfluidic chip sensor for the detection of milk adulteration through measuring the real part of the impedance and impedance phase angle. Polyamide ...
