Procedure of solidification and stabilization of heavy metals from mine waste waters adsorbed on fly ash pellets into enviromentally acceptable building material / Postupak solidifkacije i stabilizacije teških metala iz otpadnih rudničkih voda adsorbovanih na peletama u ekološki prihvatljiv građevinski materijal pepela
(Zavod za intelektualnu svojinu Republike Srbije, 2020)
Stabilization of heavy metals, especially copper, from acidic mine wastewater is performed by their solidification into sulfur polymer concrete as an environmentally acceptable building material. The procedure is carried ...
Thermovision monitoring of concrete heat of hydration / Termovizijski monitoring toplote vlaženja betona
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2020)
Usled hemijske reakcije Portland cementa, koja se uvek javlja u betonu prilikom očvršćavanja, izvesna količina toplote se razvija. Ova toplota mora biti kvantifikovana, obzirom da ona može oštetiti beton ili pomoći mu, ...
Selected Aromatic Plants Extracts as an Antimicrobial and Antioxidant Finish for Cellulose Fabric- Direct Impregnation Method
(Fibers and Polymers, 2021)
Six ethanolic extracts, obtained from anise, fennel, lavender, sage, mint, white horehound and their mixture were directly applied onto cellulose (viscose) fabric to impart antimicrobial and antioxidant functionality for ...
Optimization of lindane sorption from aqueous solution by macroporous copolymer using experimental design
(Zvornik : Faculty of Technology, 2023)
In the present study, synthesized macroporous copolymer was used for the sorption of lindane
from an aqueous solution. This organochlorine pesticide is classified, according to US EPA, as
mutagenic and teratogenic. ...
An analysis of impact testing of high strength low-alloy steels used in ship construction
(Brodogradnja, 2021)
Brittle damages have been examined widely since welding became common practice when it comes to carrying out robust structures. Welded structure of the ship hull has to be continuous. Brittle damages that occur on hull ...
Removal of lindane from aqueous solution by glycidyl methacrylate based chelating macroporous copolymer: kinetics and mechanism
(Banja Luka : University in Banjaluka, Faculty of Technology, 2023)
Lindane belongs to the persistent organic pollutants (POPs) group, which can cause carcinogenic,
endocrine, and neurological problems in an organism. The widespread presence of lindane in the
environment demands efficient ...
Principal component analysis of morphological descriptors for monitoring surface defects induced by thermal shock
(Journal of the European Ceramic Society, 2021)
Pattern recognition techniques are applied to various morphological descriptors to monitor the formation and propagation of surface defects of materials subjected to thermal shock. A low-cement high-alumina castable was ...
Non-Destructive Examination for Cavitation Resistance of Talc-Based Refractories with Different Zeolite Types Intended for Protective Coatings
(MDPI, 2023)
In many industrial processes that include fluid flow, cavitation erosion of different engineeringstructures (pumps, turbines, water levels, valves, etc.) during their operation is expected. Metallic,ceramic, and composite ...
Properties of green self-compacting concrete designed by particle packing density method
(Sisak, Croatia : Association for Promotion of Holistic Approach to Environment, 2023)
Since depletion of natural resources and the amount of construction and demolition waste haveovercome the socially and environmentally acceptable level, the construction industry must address this issue and reduce its ...
Improvement in cavitation resistance of poly (vinyl butyral) composite films with silica nanoparticles: A technical note
(Polymers & Polymer Composites, 2021)
In this study poly (vinyl butyral)/silica (PVB/SiO2) composite films were subjected to the cavitation process. The experiments were carried out with a 10 wt.% PVB solution in ethanol. Silica nanoparticles were added into ...
