Vermiculite enriched by Fe(III) oxides as a novel adsorbent for toxic metals removal
(Elsevier Sci Ltd, Oxford, 2021)
Expanded vermiculite (EV) was modified by deposition of different spinel ferrite composites on the outer surface of EV 2:1 layers in order to improve its adsorptive properties. Modifications were made by deposition of: ...
X-ray diffraction and SEM analysis of waste sulfur modification for use in concretes
(Univerzitet u Beogradu - Rudarsko-geološki fakultet, Beograd, 2021)
Secondary sulfur obtained as a by-product in the oil refining process is a major problem as an environmental pollutant. One of the possibilities of environmental protection is the use of sulfur obtained in this way as a ...
Evaluation of Adsorption Efficiency on Pb(II) Ions Removal Using Alkali-Modified Hydrochar from Paulownia Leaves
(MDPI, 2023)
In this study, hydrothermal carbonization (HTC) at five temperatures (180, 200, 220, 240,
and 260 C) was applied to transform Paulownia leaves (PL) into a carbonaceous sorbent of Pb(II)
from aqueous solutions. To enhance ...
Developing thermal insulation cement-based mortars with recycled aggregate in accordance with Net Zero principles
(Belgrade : Association for ETRAN Society, 2024)
The performance of thermo-insulation rendering mortars with alternations in ratios
of powdered cordierite and talc was examined. The goal was to confirm that recycled
kilnware cordierite can be reapplied in the mortar ...
Influence of type and quantity of filler on change of density of sulfur concrete
(University of Belgrade - Faculty of Mining and Geology, 2023)
Concrete is a material that has been used for centuries and is often modified using polymers. In the last fifty years, synthetic polymers have been used for the modification of concrete, but also for the production of ...
Mogućnost primene pirofilita kao punioca u vatrostalnim premazima / Possibility of applying pyrophylite as filler in refractory coatings
(Inženjersko društvo za koroziju, Beograd, 2020)
U radu su istraživani postupci pripreme punioca na bazi pirofilita za dobijanje vatrostalnih premaza sa kontrolisanim reološkim svojstvima. Polazni uzorci pirofilita dobijeni su iz ležišta Parsović-BiH. Istraživan je uticaj ...
Effect of corn straw pretreatment on efficiency of biogas production process: Computer simulation
(Institut za istraživanja i projektovanja u privredi, Beograd, 2020)
Anaerobic digestion is a natural process of organic material degradation by different kinds of microorganisms in the absence of oxygen. This process is used for industrial purpose to manage waste streams or to produce ...
Fabrication and characterization of luminescent Pr3+ doped fluorapatite nanocrystals as bioimaging contrast agents
(Elsevier, Amsterdam, 2020)
Fluorapatite doped with rare-earth elements has a wide-range of biomedical applications. Here, a new type of fluorapatite nanocrystals doped with praseodymium (FAP-Pr) with excitation-emission profiles in visible part of ...
Application of pyrophyllite in high-temperature treated building materials
(Beograd : Međunarodni Institut za nauku o sinterovanju, 2023)
Phyllosilicate mineral pyrophyllite is predominantly used in the ceramic industry because it exhibits high refractoriness. Due to its thermal transformation into mullite, pyrophyllite is stable at elevated temperatures, ...
Transformations of mechanochemical activated Na2CO3
(Univerzitet u Beogradu - Rudarsko-geološki fakultet, Beograd, 2022)
During mechanical activation, energy of treated material is increase to a higher level. This can lead to chemical transformation of the activated material. This is the point where we can talk about mechanochemical ...
