Tailoring the properties of waterborne polyurethanes by incorporating different content of poly(dimethylsiloxane)
(Progress in Organic Coatings, 2021)
A series of novel waterborne polyurethanes (WBPUs) was synthesized using alpha,omega-dihydroxypropyl poly(dimethylsiloxane) (PDMS), isophorone diisocyanate (IPDI), 2,2-bis-(hydroxymethyl) propionic acid (DMPA) and triethylamine ...
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 ...
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 ...
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 ...
Valorization of unexploited artichoke leaves dust for obtaining of extracts rich in natural antioxidants
(Elsevier, Amsterdam, 2021)
This study has developed an improved and fast microwave-assisted procedure for extraction of high yields of natural antioxidants from artichoke leaves dust. The material is derived as an abundant residue remained after ...
Electrokinetic and sorption properties of hydrogen peroxide treated flax fibers (Linum usitatissimum L.)
(Cellulose, 2021)
Hydrogen peroxide represents an ecologically and economically acceptable agent for bleaching of flax fibers. The influence of hydrogen peroxide treatment under different conditions, i.e. hydrogen peroxide concentrations ...
alpha-Tricalcium phosphate/fluorapatite based composite cements: Synthesis, mechanical properties, and biocompatibility
(Elsevier Sci Ltd, Oxford, 2020)
Composite cements based on alpha-tricalcium phosphate (alpha-TCP) and nanostructured fluorapatite (FAp), alpha-TCP/FAp, appropriate for dental usage as root canal filling material, have been prepared with the improved ...
