Volumetric and thermodynamic properties of binary mixtures of p-cymene with alpha-pinene, limonene and citral at atmospheric pressure and temperatures up to 323.15 K
(Journal of Molecular Liquids, 2021)
An experimental analysis of density, refractive index, speed of sound and the viscosity at atmospheric pressure and temperatures T = (288.15 to 323.15) K has been carried out for the three binary systems, i.e. (p-cymene + ...
New Theoretical Insight into Fluorination and Fluorine-Fluorine Interactions as a Driving Force in Crystal Structures
(Amer Chemical Soc, Washington, 2020)
Fluorination of compounds causes an increase in the proton-donating ability and a decrease in the proton-accepting capacity of groups in their vicinity. The formation of F center dot center dot center dot F interactions ...
Bifunctional catalytic activity of Zn1-xFexO toward the OER/ORR: seeking an optimal stoichiometry
(Royal Soc Chemistry, Cambridge, 2020)
Eco-friendly and rapid microwave processing of a precipitate was used to produce Fe-doped zinc oxide (Zn1-xFexO,x= 0, 0.05, 0.1, 0.15 and 0.20; ZnO:Fe) nanoparticles, which were tested as catalysts toward the oxygen reduction ...
Use of carbon paste electrode and modified by gold nanoparticles for selected macrolide antibiotics determination as standard and in pharmaceutical preparations
(Elsevier B.V., 2020)
In this work, carbon paste electrode (CPE) and carbon paste electrode modified with gold nanoparticics (AuNPs/CPE) were employed with rapid direct anodic square wave voltammetry (SWV) for macrolide antibiotics erythromycin ...
Nonlinear frequency response analysis of forced periodic operations with simultaneous modulation of two general waveform inputs with applications on adiabatic CSTR with square-wave modulations
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Nonlinear frequency response (NFR) method was used to evaluate the forced periodic operations and their potential for improving the system performance compared to steady-state operations. The NFR method was used to evaluate ...

(Journal of Chemical and Engineering Data, 2020)
Isopiestic measurements have been made for aqueous solutions of the common sodium cation mixtures of NaH2PO4 and Na2HPO4 at T = 298.15 +/- 0.01 K, at NaH2PO4 ionic strength fractions y = (0, 0.24851, 0.49862, 0.74544, and ...
Microstructure and cavitation erosion performance of nickel-Inconel 718 composite coatings produced with cold spray
(Elsevier Science Sa, Lausanne, 2020)
The cold spray technique was employed in this study to produce pure nickel (Ni) and nickel-Inconel 718 powder deposits on duplex stainless steel substrates. High quality coatings were manufactured using nitrogen as the ...
Micro-kinetic modelling of photocatalytic CO2 reduction over undoped and N-doped TiO2
(Royal Soc Chemistry, Cambridge, 2020)
CO2 photoreduction is studied using in-house synthesized undoped and N-doped TiO2 nanoparticle photocatalysts. Comparison with the commercial P25 TiO2 powder shows that the synthesized samples are more effective. P25 ...
Novel amino-functionalized lignin microspheres: High performance biosorbent with enhanced capacity for heavy metal ion removal
(Elsevier, Amsterdam, 2020)
Novel highly effective amino-functionalized lignin-based biosorbent in the microsphere geometry (A-LMS) for removal of heavy metal ions, was synthesized via inverse suspension copolymerization of kraft lignin with poly(ethylene ...
Waste Jute Fabric as a Biosorbent for Heavy Metal Ions from Aqueous Solution
(Korean Fiber Soc, Seoul, 2020)
The influence of the chemical composition on the biosorption potential of waste jute fabric for Ni2+, Cu2+, and Zn(2+)was investigated. The raw jute fabric was treated with sodium hydroxide or sodium chlorite to selectively ...
