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 ...
Biocontrol of economically significant diseases in order to increase the yield of pot marigold and valerian seeds and potato tubers / Biokontrola ekonomski značajnih bolesti u cilju povećanja prinosa semena nevena i odoljena i krtola krompira
(Serbian Association of Plant Breedings and Seed Producers, 2020)
The paper examines the effect of the application of three different preparations on the presence of four economically significant diseases in the crops of pot marigold, valerian and potato. On pot marigold, the intensity ...
Absorption and fluorescence spectral properties of azo dyes based on 3-amido-6-hydroxy-4-methyl-2-pyridone: Solvent and substituent effects
(Elsevier Sci Ltd, Oxford, 2020)
A series of nine 5-(4-substituted phenylazo)-3-amido-6-hydroxy-4-methyl-2-pyridones were synthesized and characterized by FT-IR, H-1 and C-13 NMR, UV-Vis, and PL spectroscopy. Photophysical properties of the dyes were ...
Quantitative comparison of iron and cobalt based catalysts for the Fischer-Tropsch synthesis under clean and poisoning conditions
(Elsevier, Amsterdam, 2020)
Quantitative data comparing iron and cobalt based catalysts for the Fischer-Tropsch synthesis (FTS) are scarce due to the fact that these two kinds of catalysts typically utilize different process conditions. This paper ...
The chicken eggshell calcium oxide ultrasonically dispersed over lignite coal fly ash-based cancrinite zeolite support as a catalyst for biodiesel production
(Elsevier, 2021)
Lignite coal fly ash (FA) from a domestic thermal power plant was converted into a pure cancrinite zeolitic material (ZMFA) using a novel, custom-made, rotating autoclave reactor system by a short-term alkali activation ...
Optimization of Reactive Diluent for Bio-Based Unsaturated Polyester Resin: A Rheological and Thermomechanical Study
(Polymers, 2021)
Nowadays, unsaturated polyester resins (UPR) are mainly obtained from non-renewable resources. The ever-increasing regulations and the continuous demand for more sustainability have led to extensive research towards more ...
Improved recovery of protein from soy grit by enzyme-assisted alkaline extraction
(Elsevier Sci Ltd, Oxford, 2020)
Recovery of protein from soy grit, its functional properties and possibility for the reduction of time of conventional alkaline extraction by the assistance of enzymes were studied. Enzymatic treatment was performed by ...
Effect of composition and method of preparation of 2-hydroxyethyl methacrylate/gelatin hydrogels on biological in vitro (cell line) and in vivo (zebrafish) properties
(Springer, Dordrecht, 2020)
We have studied the effect of compositions and methods of preparation on the physico-chemical and biocompatible behavior of the hydrogel matrices. Hydrogel matrices are synthesized by free radical polymerization of ...
Hybrid material based on subgleba of mosaic puffball mushroom (Handkea utriformis) as an adsorbent for heavy metal removal from aqueous solutions
(Journal of Environmental Management, 2021)
The alkali treated subglebal tissue of the mosaic puffball (Handkea utriformis) (Sa) and Sa modified with hydroxyapatite (Sa-HAp), obtained by successive ionic layer adsorption and reaction (SILAR) method, were used for ...
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: ...
