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 ...
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 ...
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 ...
Plant Extracts Rich in Polyphenols as Potent Modulators in the Growth of Probiotic and Pathogenic Intestinal Microorganisms
(Frontiers in Nutrition, 2021)
Medicinal plants and their extracts contain substantial quantities of polyphenols. As metabolically active plant metabolites, polyphenols are food components with a wide range of biological activities. Given their poor ...
The chicken eggshell calcium oxide ultrasonically dispersed over lignite coal fly ash-based cancrinite zeolite support as a catalyst for biodiesel production
(Fuel, 2021)
Lignite coal fly ash (FA) from a domestic thermal power plant was converted into a pure cancrinite zeolitic material (ZM(FA)) using a novel, custom-made, rotating autoclave reactor system by a short-term alkali activation ...
Antimicrobial and biological effects of polyaniline/polyvinylpyrrolidone nanocomposites loaded with silver nanospheres/triangles
(New Journal of Chemistry, 2021)
Two silver-polyaniline/polyvinylpyrrolidone (Ag-PANI/PVP) nanocomposites were prepared using in situ integration of silver nanoparticles (AgNPs) during oxidative aniline polymerization, accelerated by the presence of PVP, ...
Synthesis and Characterization of Azido Esters as Green Energetic Plasticizers
(Propellants Explosives Pyrotechnics, 2021)
Three azido-esters based green energetic plasticizers were synthesized from their chlorides including DEGBAA (diethyleneglycol bis(azidoacetate)), DPGBAA (dipropyleneglycol bis(azidoacetate)) and HETTAA (hexanetriol ...
