The influence of thermodynamic parameters on alkaline activators of geopolymers and the structure of geopolymers
(Macedonian Journal of Chemistry and Chemical Engineering, 2021)
Thermodynamic parameters (densities, viscosities, speed of sound, and refractive index) of four series of alkaline activators were determined over the temperature range from 15 to 60 degrees C for the process of ...
Reuse potential of functionalized thermoplastic waste as reinforcement for thermoset polymers: Mechanical properties and erosion resistance
(SAGE Publications Ltd., 2021)
Two types of polymer waste materials, poly(ethylene terephthalate) (PET) and polycarbonate based Colombian Resin (CR-39), were used for the designing of fully recycled composite materials. Waste PET was employed for the ...
Thermodynamic study of ester diethyl tartrate and its binary systems with iso-alcohols
(Elsevier, Amsterdam, 2020)
Densities of pure ester diethyl tartrate and alcohols isobutanol and isopentanol are measured on high pressures up to 60 MPa and temperatures from 293.15 K to 413.15 K, while thermophysical properties for two systems ester ...
Sponge-like europium oxide from hollow carbon sphere as a template for an anode material for Reactive Blue 52 electrochemical degradation
(Materials Chemistry and Physics, 2021)
The textile industry is one of the major pollutants of waterbodies with effluents high in biochemical and chemical oxygen demand values, high values of total dissolved solids, total suspended solids, and low dissolved ...
Evaluation of stability and functionality of BaCe1-xInxO3-delta electrolyte in a wider range of indium concentration
(Journal of Advanced Ceramics, 2022)
The properties of BaCe1-xInxO3-delta (x = 0.05, 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, and 0.40) as proton conducting electrolyte are examined. The dense electrolyte is formed after sintering at 1300 degrees C for 5 h in air. ...
The effect of incompletely condensed polyhedral oligomeric silsesquioxanes (POSS) on hybrid film adhesion
(Elsevier Sci Ltd, Oxford, 2020)
The objective of this study was to investigate the influence of polyhedral oligomeric silsesquioxane (POSS) structure on the adhesion behaviour of composite films onto a metallic surface. The composite films consisted of ...
Surface optical phonon (SOP) mode in ZnS/Poly (methylmethacrylate) nanocomposites
(Elsevier, Amsterdam, 2020)
The polymer nanocomposite ZnS/Poly (methylmethacrylate) was prepared by the solution casting method and its structural and optical properties were investigated using XRD, SEM, TEM, HRTEM, and Raman spectroscopy. The basic ...
Spatial distribution, radiological risk assessment and positive matrix factorization of gamma-emitting radionuclides in the sediment of the Boka Kotorska Bay
(Marine Pollution Bulletin, 2021)
Surface sediment from the Boka Kotorska Bay (Adriatic Sea) was analyzed for the content of technogenic cesium (137Cs) and naturally occurring (40K, 226Ra, 232Th, 238U) radionuclides. The activity concentrations of the ...
Freeze vs. Spray Drying for Dry Wild Thyme (Thymus serpyllum L.) Extract Formulations: The Impact of Gelatin as a Coating Material
(Molecules, 2021)
Freeze drying was compared with spray drying regarding feasibility to process wild thyme drugs in order to obtain dry formulations at laboratory scale starting from liquid extracts produced by different extraction methods: ...
Sinigrin Encapsulation in Liposomes: Influence on In Vitro Digestion and Antioxidant Potential
(Polish Journal of Food and Nutrition Sciences, 2021)
Encapsulation of sinigrin in liposomes with the proliposomal method was performed in order to evaluate the effect of this process on in vitro simulated digestion and antioxidant potential of sinigrin. The recovery of ...
