In this paper, the influence of process parameters on the morphological properties of fine precipitated hydrate was examined. The research was conducted with the aim of synthesizing fine precipitated aluminum hydroxide from the aluminate solution obtained by the Bayer process. Fine precipitated hydrates obtained in this way are mostly used in the n...

Fat soluble vitamins, including vitamin D, are not sufficiently represented in the human diet. Although vitamin D can be synthesized in the body by direct exposure of the body to the sun, often people don’t get enough sun exposure to assure enough vitamin D. Previous research has established that vitamin D deficiency is considered to be a hig...

The concentration of copper (Cu) was determined in 110 samples of fruit (n = 31) and vegetable products (n = 79), collected during the period from January 2015 to December 2019. Fruit and vegetable products originate from 17 countries, including Serbia. Samples were analysed by inductively coupled plasma – optical emission spectrometry (ICP-O...

In this paper, conventional solid-liquid extraction and ultrasound-assisted extraction were utilized for (poly)phenols extraction from black elderberry flowers. The extraction lasted 30 to 120 min, with a solid-to-solvent ratio of 1:15 w/v and 1:30 w/v and solvents of 30% and 60% ethanol. Total (poly)phenols, flavonoids and anthocyanins contents we...

The experimental values of the friction factor (fp) at ambient and elevated temperatures as well as of the heat transfer coefficient (hp) were used to establish the analogy between momentum and heat transfer in gas-solid packed beds of monosized spherical glass particles, as jH=fp/22 or jHε=fp/50. Also, the Chilton-Colburn type of momentum-...

A gluten-free diet is the only available therapy for people with celiac disease (CD) and wheat allergy (WA). Given that this type of diet is difficult to implement because there is a possibility that gluten-free products could be contaminated with gluten, the aim of this paper was to examine the effect of cold plasma treatment on gluten proteins pr...

The electrohydrodynamics’ (EHD) perfect dielectric model was added into computational fluid dynamics (CFD) software OpenFOAM in order to improve its usability for the EHD field and specifically for the mentioned model. Based on the investigated literature, it can be said that this is the most complete implementatiton of the said model. Two se...
