Porous cordierite-supported polyethyleneimine composites for nickel(II) and cadmium(II) ions removal
(Desalination Publications, 2020)
Industrial/technological growth is directly connected with environmental pollution, but its influence can be minimized through pollution abatement approaches such as the treatment of industrial wastewater. In this study, ...
Thermal Resistance of Alkali Activated Binders Synthesized Using the Fly Ash and Steel Slag
(Belgrade : Materials Research Society of Serbia, 2015)
The thermal resistance of alkali-activated binders based on fly ash (FA), electric arc furnace slag (EAFS) and their FA/EAFS blends was assessed. Compressive strengths of samples before and after firing were measured. The ...
Sinteza i struktura bakterijske celuloze primenom bakterija sirćetnog vrenja
(Čačak : Univerzitet u Kragujevcu, Agronomski fakultet, 2021)
Kao jedan od najzastupljenijih biopolimera na Zemlji, celuloza je našla primenu u prehrambenoj industriji, biomedicini i biotehnologiji. Dobijanje celuloznih vlakana iz biljaka je praćeno prisustvom nusproizvoda, čije je ...
Electrical properties of isothermally sintered cordierite-based ceramics as function of sintering and activation time / Električna svojstva izotermski sinterovane keramike na bazi kordierita kao funkcija vremena sinterovanja i aktivacije
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2021)
The mechanical activation of the starting mixtures of cordierite (2MgO*2Al2O3*5SiO2) with 5.00 mass % TiO2 was performed in a high energy ball mill during 10-80 min. The applied compaction pressure before the sintering ...
Influence of sintering time on density properties and SEM analysis of cordierite-based ceramics / Uticaj vremena sinterovanja na gustinu i SEM analiza kordijeritne keramike
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2021)
The mechanical activation of the starting mixtures of cordierite (2MgO*2Al2O3*5SiO2) with 5.00 mass % TiO2 was performed in a high energy ball mill during 10-80 min. The applied compaction pressure before the sintering ...
Measurement of dielectric permitivity using coaxial chambers and electromagnetic-modeling software
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
Our research group has developed a method for measurement of complex relative permittivity of various dielectric materials in the frequency range from around 1 kHz up to several GHz. Material samples have preferably a disk ...
Preparation and characterization of ZrB2-TiB2 based composites for hypersonic systems
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
ZrB2 ceramics are considered potential materials for hypersonic systems in view of the melting point exceeding 3000 °C and excellent ablation resistance. Second phases, including SiC or CrB2, further improve the oxidation ...
National Energy and Climate Planning in Serbia: From Lagging Behind to an Ambitious EU Candidate?
(Aalborg : Aalborg University Press, 2021)
Just in the immediate neighbourhood of the European Union (EU), the Republic of Serbia, one of the Western Balkan (WB) EU candidate countries, is lagging behind in the process of energy transition regardless of technological ...
High Heat Treatment of Goat Cheese Milk. The Effect on Sensory Profile, Consumer Acceptance and Microstructure of Cheese
(Basel : MDPI AG, 2021)
Goat cheeses from high heat treated milk (HHTM: 80 °C/5 min (E1) and 90 °C/5 min (E2)), could be regarded as new products, compared to their analogues made from commonly pasteurized milk (65 °C/30 min (C)). Descriptive ...
Pyrosol preparation and structural characterization of SnO2 thin films
(Elsevier Science Sa, Lausanne, 2003)
Polycrystalline tin oxide thin films were prepared from ethanol solution Of SnCl2.H2O (concentrations: 0.05, 0.1, 0.2 and 0.4 mol/dm(3)) at different substrate temperatures ranging from 300 to 450 degreesC. The kinetic ...
