Analysis of thermophysical properties of binary systems containing ethyl acetate and 1-propanol or 1-butanol
(Savez hemijskih inženjera, Beograd, 2020)
The aim of this research is the experimental determination of density, viscosity, refractive index and speed of sound for binary mixtures of the ester ethyl acetate and alcohols. Experimental measurements were carried out ...
Influence of yarn folding on uv protection properties of hemp knitted fabrics
(Savez hemijskih inženjera, Beograd, 2016)
In the last years the media have highlighted the damage of the ozone layer and the resulting increase of ultraviolet radiation (UVR) reaching the Earth's surface. Prolonged and repeated, both occupational and recreational, ...
The influence of migration processes in gunpowder charge on the quality of mortar ammunition
(Savez hemijskih inženjera, Beograd, 2017)
The study describes the results of static, physicochemical and ballistic examination of double-based gunpowder charges, in order to establish the deviations from the demanded quality of mortar ammunition. The examinations ...
Microfiltration with periodic gas backwashing as an alternative technique for increasing permeate flux
(Savez hemijskih inženjera, Beograd, 2018)
In this paper, the influence of operating parameters (transmembrane pressure, temperature, the flow rate of retentate) on the cross - flow microfiltration of synthetic fruit juice and periodic backwashing with air was ...
Optimization of spray drying conditions for production of Achillea millefolium extract powder
(Hemijska industrija, 2021)
In this study, a spray drying process of yarrow (Achillea millefolium L.) liquid extracts was optimized by using the response surface methodology. The study aimed to determine the influence of temperature (120-195 degrees ...
