Karakteristike ćelijskog zida kukuruzne biomase nakon oksidativnog tretmana
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2022)
Najveći deo ćelijskog zida viših biljaka se sastoji od tri polimerna molekula, celuloze, hemiceluloze i lignina. Imajući u vidu zastupljenost ova tri polimera u prirodi, lignocelulozna biomasa se danas smatra važnom sirovinom ...
Fly ash modified waste cotton and cotton-polyester yarns for removal of heavy metals from water
(Society of Physical Chemists of Serbia, 2022)
Using two types of industrial waste materials (yarns and fly ash), adsorbents for removing heavy
metal ions from water were obtained. To improve the adsorption efficiency of cotton and cottonpolyester yarns, modification ...

Numerical simulation of 14Mov6-3 steel CT-specimen Fracture Behavior
(Elsevier B.V., 2022)
Steel grade 14MoV6 3 is used for manufacturing of boilers and steam pipelines designed for steam temperatures up to 560 °C. This paper presents the numerical simulation of a CT-specimen, using the finite element method. ...
Effect of temperature and specimen orientation on Charpy impact toughness
(Elsevier B.V., 2022)
Steel grade 14MoV6 3 is used for manufacturing of boilers and steam pipelines designed for steam temperatures up to 560°C. This paper presents the experimental analysis which included impact toughness test. The analysis ...
Hydroxyapatite-based Bioceramic Dental Inserts as Dentin Substitute
(Belgrade : Serbian Academy of Sciences and Arts, 2022)
Tooth caries presents one of the most common diseases worldwide, and its treatment involves
removal of the decayed tooth structure, and the cavity restoration using restorative dental materials. Resin based composites ...
Adsorption of selected pharmaceuticals on LDPE, PA, and PET microplastics
(Srpsko hemijsko društvo, 2022)
Unappropriated disposing of unused drugs leads to an increase in their concentration in the
environment. Furthermore, wastewater treatment plants are not sufficient to prevent the
transport of drugs. Microplastics (MPs), ...
COMPARATIVE ANALYSIS OF Pb2+ SEPARATION USING NATURAL AND SYNTHETIC SILICATE MATERIALS
(Society of Physical Chemists of Serbia, 2022)
In this study, the adsorption capacity and removal efficiency of lead using various metal-oxide materials from aqueous solution have been analyzed. Two SiO2-based materials, natural (loam) and synthesized (metal-oxide ...
Effects of Over-Loading on Pressure Vessel Integrity
(Elsevier B.V., 2022)
The effect of proof over-pressure on pressure vessels structural integrity is analysed. Risk based approach is applied using Failure Analysis Diagramme to assess likelihood of failure. Special attention is paid to crack-like ...
Effect of alkali modification on adsorption efficiency of fly ash
(Faculty of Technology Banja Luka, 2022)
As coal combustion in thermal power plants generates huge amounts of waste such as bottom ash and fly ash, there is a need to find new applications for these materials. One of the ways of its reuse is chemical or thermal ...
