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 ...
Twin nucleation from a single lt c plus a > dislocation in hexagonal close-packed crystals
(Acta Materialia, 2021)
Twinning plays an important role in governing the balance between strength and ductility in hexagonal-close-packed (HCP) metals. Here, we report a combined experimental and theoretical study of twin nucleation from a single ...
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 ...
Sustainable and fast synthesis of zinc-phthalocyanine for gamma radiation dosimeter application
(Elsevier Ltd., 09-2024)
In the present research, the two different systems of dye based on zinc phthalocyanine were prepared by microwave-induced synthesis and conventional methods. They were evaluated as new effective chemical-based dosimeters ...
Physico-chemical, structural, and adsorption properties of amino-modified starch derivatives for the removal of (in)organic pollutants from aqueous solutions
(Elsevier B.V., 2023)
In this study, an environmentally sustainable process of crystal violet, congo red, methylene blue, brilliant green, Pb2+, Cd2+, and Zn2+ ions adsorption from aqueous solutions onto amino-modified starch derivatives was ...
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 ...
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. ...
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 ...
Irradiated fig pomace pyrochar as a promising and sustainable sterilized sorbent for water pollutant removal
(Elsevier Ltd, 2024)
Irradiated fig pomace pyrochar (IrrPyrFP) is noteworthy as a novel sterilized low-cost sorbent of BTEX, pesticides, and Pb2+ ions. It was produced by applying pyrolysis treatment followed by gamma irradiation modification ...
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. ...
