A universal transportation model for reverse osmosis systems
(Computers & Chemical Engineering, 2021)
This paper presents a new transport model for reverse osmosis (RO) systems, which combines irreversible thermodynamics, together with solution-diffusion theory. The simplifications adopted by the classical theory for ...
Novel composite scaffolds based on alginate and Mg-doped calcium phosphate fillers: Enhanced hydroxyapatite formation under biomimetic conditions
(Journal of Biomedical Materials Research Part B-Applied Biomaterials, 2021)
In the present study, we synthesized hydroxyapatite (HAP) powders followed by the production of alginate based macroporous scaffolds with the aim to imitate the natural bone structure. HAP powders were synthesized by using ...
Radon and thoron exhalation rate measurements from building materials used in Serbia
(Nukleonika, 2020)
The second most important source of indoor radon, after soil beneath dwelling, is building material. With the increase in environmental awareness and new energy-saving policies, residents tend to replace the existing windows ...
Formulation and characterization of liposomal encapsulated systems of bioactive ingredients from traditional plant mountain germander (Teucrium montanum L.) for the incorporation into coffee drinks
(Elsevier Ltd., 2022)
Conventional and innovative (microwave-assisted and subcritical water extraction) techniques were applied to investigate the bioactive content of traditional plant - Teucrium montanum. Verbascoside and echinacoside, ...
Nonlinear frequency response analysis: a recent review and perspectives
(Current Opinion in Electrochemistry, 2021)
The nonlinear frequency response analysis (NFRA) can be seen as an extension of electrochemical impedance spectroscopy. NFRA gives a full and detailed representation of the system response and can establish a connection ...
Determination of LCF Plastic and Elastic Strain Components of Steel
(Springer Science and Business Media B.V., 2022)
The behavior of steel in low-cycle fatigue (LCF) is tested experimentally, in accordance with ISO 12106:2017 (E) and/or ASTM E 606-04. For this purpose, smooth specimens which are exposed to low-cycle fatigue at several ...
Saddle Point Optimality Criteria and Duality for Convex Continuous-Time Programming Problem
(Department of Mathematics, Faculty of Science and Mathematics, University of Niš, 2022)
In this paper, convex continuous-time programming problem with inequality type of constraints is considered. We derive new saddle point optimality conditions and classical duality results such as weak and strong duality ...
An Efficient Electrochemical Sensing of Caffeic Acid at Thermolysis Prepared Urea-formaldehyde Resin Modified with Fe(III) and Ti(IV) Oxide Particles
(Electrochemical Science Group, 2022)
Urea-formaldehyde resin (UF) is primarily used as an adhesive applied in the wood composites industry. In this work, we found that this resin modified with metal compounds could be a good starting point to produce ...
Towards enhanced dyeing process: arylazo pyridone dyes / Poboljšanje procesa bojenja iz perspektive arilazo piridonskih boja
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Društvo za procesnu tehniku, 2020)
Azo pyridone dyes as a group of synthetic disperse azo dyes are commonly used in textile fiber dyeing. Traditionally, synthetic fibers are tinted in an acid environment, whereas their stability has been ruptured by base ...
Encapsulation of Lactobacillus rhamnosus in Polyvinyl Alcohol for the production of L-(+)-Lactic Acid
(Process Biochemistry, 2021)
Poly(vinyl alcohol) (PVA) was investigated as a carrier for Lactobacillus rhamnosus ATCC 7469 cells for application in L-(+)-lactic acid (LA) fermentation on low-cost food industry by-products. Brewer?s spent grain (BSG) ...
