Determination of temperature stresses in CWR based on measured rail surface temperatures
(Construction and Building Materials, 2021)
The main aim of conducted research is determination of temperature stresses due to the uneven temperature distribution in CWR. This paper presents a methodology for determination of temperature stresses in CWR based on (1) ...
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 ...
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 ...
Multifunctional jute fabrics obtained by different chemical modifications
(Springer, 2020)
The aim of the present research is first to reduce the jute fabric non-cellulosic components by using different chemical modifications (i.e. alkali and oxidative) and then to analyze their influence on the jute fabric ...
Obtaining jute fabrics with enhanced sorption properties and "closing the loop" of their lifecycle
(Industrial Crops and Products, 2021)
The objective of this investigation was to obtain jute fabrics with enhanced sorption properties (by using simple and cost-effective alkali and oxidative modifications) and a long life cycle. The applied alkali modifications ...
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 ...
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 ...
Analysis and experimental demonstration of forced periodic operation of an adiabatic stirred tank reactor: Simultaneous modulation of inlet concentration and total flow-rate
(Chemical Engineering Journal, 2021)
It is well known, that forced periodic operation possesses the potential for process improvements. Nevertheless, only a small number of applications is reported, due to complex realization, limited predictability and high ...
Development of comfortable and eco-friendly cellulose based textiles with improved sustainability
(Elsevier Sci Ltd, Oxford, 2020)
Considering specific mechanical, hygienic and protective properties of hemp, as well as its positive
sustainability aspects, the raising role of hemp fibres in the textile sector can be expected. The limited
deformability ...
