Kinetics of Chalcopyrite Leaching by Hydrogen Peroxide in Sulfuric Acid
(MDPI, Basel, 2019)
In ores, chalcopyrite is usually associated with other sulfide minerals, such as sphalerite, galena, and pyrite, in a dispersed form, with complex mineralogical structures. Concentrates obtained by flotation of such ores ...
Influence of the heat treatment on the tribological characteristics of the Ti-based alloy for biomedical applications
(Univerzitet u Kragujevcu - Fakultet inženjerskih nauka, Kragujevac, 2009)
The influence of diverse heat treatments on micro-structural and tribological characteristics of Ti-6Al-4V ELI (mass%) alloy, which is used as implant material in biomedical engineering, was investigated on a block-on-disc ...
Electrophysical properties of nonwoven viscose/polypropylene fabrics
(Skopje : Society of chemists and technologists of Macedonia, 2018)
Textile materials like woven, knitted and nonwoven fabrics are good insulators with very high
electrical resistance. It is known that dielectric properties (effective dielectric permeability, electrical
conductivity, and ...
Kinetics and isotherms modeling of silver removal onto macroporous amino sorbent
(Zvornik : Faculty of Technology, 2023)
Silver as one of the most known precious metal is used on a large scale in various industrial
branches and the release of silver ions from such industrial activities potentially can cause
serious environmental problems. ...
Selenate adsorption from water using the hydrous iron oxide-impregnated hybrid polymer
(MDPI, Basel, 2020)
Hybrid adsorbent, based on the cross-linked copolymer impregnated with hydrous iron oxide, was applied for the first time for Se(VI) adsorption from water. The influence of the initial solution pH, selenate concentration ...
Development and Validation of a Long-Term 3D Glioblastoma Cell Culture in Alginate Microfibers as a Novel Bio-Mimicking Model System for Preclinical Drug Testing
(Brain Sciences, 2021)
Background: Various three-dimensional (3D) glioblastoma cell culture models have a limited duration of viability. Our aim was to develop a long-term 3D glioblastoma model, which is necessary for reliable drug response ...
Immobilization of heavy metal ions Zn2+, Ni2+, Pb2+ and Cu2+ in the structure of cement-based materials / Imobilizacija teških metalnih jona Zn2+, Ni2+, Pb2+ i Cu2+ u strukturi materijala na bazi cementa
(Engineering Society for Corrosion, Belgrade, Serbia, 2020)
Natural zeolite and bentonite were utilized as mineral additives in the mix-design of environmentally safe cement-based building materials. The adsorptive abilities of these two clayey raw materials, i.e. their affinity ...
Preparation and properties of hydrogen peroxide oxidized starch for industrial use
(Savez hemijskih inženjera, Beograd, 2020)
Oxidized starch, an additive used in paper manufacturing and products for construction industry, is usually produced using harmful oxidant, such as hypochlorites or periodates. In this study, a simple and efficient ...
Reductive removal of hexavalent chromium in aqueous solution by magnetic amino-functionalized polymer nanocomposite
(Banja Luka : University PIM, 2023)
The contamination of water with chromium is a global issue that is especially
severe in developing countries with intensive mining and heavy industry (South
Africa, Pakistan, and India) [1,2]. Trivalent Cr(III) and ...
Exploitation properties of ni-pd/al2o3 catalyst supported on ceramic foam
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The goal of this research was to examine exploitation properties of Ni-Pd/Al2O3 catalyst supported on alpha-Al2O3 based foam in the dry methane reforming. The catalyst was prepared by using aerosol method. Chloride precursors ...
