Effect of the Degree of Conversion on Mechanical Properties and Monomer Elution from Self-, Dual- and Light-Cured Core Composites
(Materials, 2021)
The objective of this work was to measure and correlate the degree of conversion (DC), mechanical properties and monomer elution from self-, dual- and light-cured core composites. Five samples of each of the following ...
Utilization of supercritical CO2 in bioactive principles isolation from Helichrysum italicum and their adsorption on selected fabrics
(Journal of Supercritical Fluids, 2021)
Helichrysum italicum (Roth) G. Don fil., Asteraceae, possesses numerous secondary plant metabolites with a wide range of biological activities. Yet, data on the potential of supercritical fluid extraction (SFE) in their ...
Nonlinear frequency response analysis: a recent review and perspectives
(Current Opinion in Electrochemistry, 2021)
The nonlinear frequency response analysis (NFRA) can be seen as an extension of electrochemical impedance spectroscopy. NFRA gives a full and detailed representation of the system response and can establish a connection ...
A universal transportation model for reverse osmosis systems
(Computers & Chemical Engineering, 2021)
This paper presents a new transport model for reverse osmosis (RO) systems, which combines irreversible thermodynamics, together with solution-diffusion theory. The simplifications adopted by the classical theory for ...
Development of advanced floating poly(lactic acid)-based materials for colored wastewater treatment
(Journal of Supercritical Fluids, 2021)
The release of industrial wastewater into the ecosystem prompted our research on the development of an efficient and biodegradable material that can be used for wastewater treatment. We optimized preparation of porous ...
Assessing the potential of para-donor and para-acceptor substituted 5-benzylidenebarbituric acid derivatives as push-pull electronic systems: Experimental and quantum chemical study
(Spectrochimica Acta Part A-Molecular and Biomolecular Spectroscopy, 2021)
Electronic interactions in donor-pi-linker-acceptor systems with barbituric acid as an electron acceptor and possible electron donor were investigated to screen promising candidates with a push-pull character based on ...
Bio-membrane based on modified cellulose, lignin, and tannic acid for cation and oxyanion removal: Experimental and theoretical study
(Process Safety and Environmental Protection, 2021)
Two optimized methods, based on epoxy-amino reactivity of the Cellulose fibres (Cell) modified with diethylenetriamine (Cell-DETA), (3-Glycidyloxypropyl)trimethoxysilane (Cell-Glymo), Lignin modified with epichlorohydrine ...
Technologically Sustainable Route for Metals Valorization from Jarosite-PbAg Sludge
(Minerals, 2021)
By-products from zinc hydrometallurgy are classified as hazardous waste with strong leaching toxicities. Even though numerous research papers are dedicated to valorizing valuable metals in it, the primary management route ...
Synthesis of Silica Particles Using Ultrasonic Spray Pyrolysis Method
(Metals, 2021)
Silica has sparked strong interest in hydrometallurgy, catalysis, the cement industry, and paper coating. The synthesis of silica particles was performed at 900 degrees C using the ultrasonic spray pyrolysis (USP) method. ...
Semi-Crystalline Copolymer Hydrogels as Smart Drug Carriers: In Vitro Thermo-Responsive Naproxen Release Study
(Pharmaceutics, 2021)
In this study, poly(N-isopropylacrylamide-co-2-hydroxypropyl methacrylate) hydrogels were synthesized using free radical initiated copolymerization method. Four hydrogels with different cross-linker concentrations were ...
