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 ...
Extraction of phenolic compounds from agro-industrial wastes and evaluation of their antioxidative potential
(Skopje, Macedonia : Consulting and Training Center - KEY, 2021)
Constant world population growth imposes the need for the production of more food, and as a consequence, has an increase in the organic-rich wastes. These agro-industrial wastes represent problem from the environmental ...
Effect of organoclay modifier structure on the viscoelastic and thermal properties of poly(methyl methacrylate)/organoclay nanocomposites
(Springer, New York, 2021)
Poly(methyl methacrylate) (PMMA)/clay nanocomposites (NCs) were prepared by suspension polymerization of methyl methacrylate in the presence of two different organoclays (Cloisite 30B, Cloisite 15A) with clay loading ranged ...
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) ...
Environmental Safety Aspects of Solid Residues Resulting from Acid Mine Drainage Neutralization with Fresh and Aged Red Mud
(Water Air and Soil Pollution, 2021)
Acid mine drainage (AMD) remediation by red mud (RM) can benefit process sustainability and waste valorization. Though the AMD properties upon using RM have been broadly investigated, the key features and the environmental ...
Modification of PET and PA fabrics with alginate and copper oxides nanoparticles
(Composite Interfaces, 2021)
The aim of this study was to fabricate novel antimicrobial nanocomposite materials by in-situ syntheses of Cu-based nanoparticles on PET and PA fabrics. The synthesis comprised three steps: (i) modification of PET and PA ...
Green pH- and magnetic-responsive hybrid hydrogels based on poly(methacrylic acid) and Eucalyptus wood nanocellulose for controlled release of ibuprofen
(Cellulose, 2021)
pH- and magnetic-sensitive hybrid hydrogels based on poly(methacrylic acid) (PMAA), nanocellulose (NC), carboxymethyl cellulose (CMC) and magnetite particles (MN) were prepared as ibuprofen delivery system. NC was isolated ...
Oxidized Hemp Fibers with Simultaneously Increased Capillarity and Reduced Moisture Sorption as Suitable Textile Material for Advanced Application in Sportswear
(Fibers and Polymers, 2021)
Applications of hemp fibers, as a promising natural material in the textile field, mostly require improved fiber properties. In this paper, the oxidation of hemp fibers with potassium permanganate was applied to reduce the ...
Novel azo pyridone dyes based on dihydropyrimidinone skeleton: Synthesis, DFT study and anticancer activity
(Dyes and Pigments, 2021)
Seven novel azo dyes with 2-pyridone and dihydropyrimidinone moieties have been synthesized and thoroughly characterized. The azo-hydrazone tautomerism has been investigated by experimental and theoretical approaches. The ...
