A LFER Kinetic Study of The Reaction of 5-Substituted Orotic Acids with Diazodiphenylmethane
(Wiley, Hoboken, 2016)
Linear free energy relationships (LFER) were applied to the kinetic data for the reaction of 5-substituted orotic acids, series 1, with diazodiphenylmethane (DDM) in N,N-dimethylformamide and compared with results obtained ...
Impact analysis of airborn pollution due to magnesium slag deposit and climatic changes condition
(Soc Ecological Chemistry & Engineering, Opole, 2012)
The impact of airborne pollution by slag from magnesium production was analyzed under different climate conditions. The slag is characterized by X-ray diffraction analysis, scanning electron microscopy, differential thermal ...
Preparation and properties of hydrogen peroxide oxidized starch for industrial use
(Savez hemijskih inženjera, Beograd, 2020)
Oxidized starch, an additive used in paper manufacturing and products for construction industry, is usually produced using harmful oxidant, such as hypochlorites or periodates. In this study, a simple and efficient ...
Adsorption performances and antimicrobial activity of the nanosilver modified montmorillonite clay
(Desalination Publ, Hopkinton, 2020)
The synthesis and adsorption potential of Cy-npAg, obtained by modification of raw montmorillonite clay (raw-Cy) with silver nanoparticle (npAg), was studied in this work. Optimization procedure, with respect to time, ...
The physicochemical properties of the deep eutectic solvents with triethanolamine as a major component
(Srpsko hemijsko društvo, Beograd, 2020)
Different deep eutectic solvents (DESs) of triethanolamine (TEOA) and oxalic acid (OA), glacial acetic acid (AA), L-(+)-lactic acid (LA), oleic acid (OLA), glycerol (G), ethylene glycol (EG), propylene glycol (PEG), choline ...
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 ...
Image analysis as a useful tool for fast detection of dimensional and structural changes of poly(ethylene terephthalate) containers
(Savez hemijskih inženjera, Beograd, 2018)
The aim of this paper is to present image analysis as a useful technique for fast, reliable and non-destructive detection of dimensional and structural changes in polymers. The possibility of applying image analysis was ...
Effects of waste sulfur content on properties of self-compacting concrete
(Consejo Superior Investigaciones Cientificas-Csic, Madrid, 2020)
Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore ...
