Development of a packed bed bioreactor for cartilage tissue engineering / Razvoj bioreaktorskog sistema sa pakovanim slojem za primenu u inženjerstvu tkiva hrskavice
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2006)
Efficient transport of regulatory molecules is one of the main requirements for directing the growth and differentiation of bone marrow stromal cells (BMSC). We have designed and utilized a packed bed bioreactor system for ...
Impact analysis of airborn pollution due to magnesium slag deposit and climatic changes condition
(Soc Ecological Chemistry & Engineering, Opole, 2012)
The impact of airborne pollution by slag from magnesium production was analyzed under different climate conditions. The slag is characterized by X-ray diffraction analysis, scanning electron microscopy, differential thermal ...
Determination of AL2O3particle size in Cu-AL2O3 nanocomposite materials using UV spectrophotometry / Određivanje veličine čestica AL2O3 u nanokompozitnim materijalima iz sistema Cu-AL2O3 primenom UV spektrofotometrije
(Savez inženjera metalurgije Srbije, Beograd, 2008)
In order to achieve improved mechanical properties of dispersion strengthened nanocomposite, without influencing electrical and thermal conductivity it is necessary for dispersoide to be nano sized and uniformly distributed ...
The influence of residual stresses on welded joints and other inhomogeneous materials with cracks / Uticaj zaostalih napona na ponašanje zavarenih spojeva i drugih nehomogenih materijala sa prslinama
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2009)
Residual stresses in many structural components are often produced during the fabrication or bonding processes, due to the cooling from elevated temperatures. Examples for such behavior are: welded and soldered joints, ...
Extending waste paper, cellulose and filler use beyond recycling by entering the circular economy creating cellulose-CaCO3 composites reconstituted from ionic liquid
(Springer Science and Business Media B.V., 2022)
Cellulose-fibre lifecycle is severely limited within today’s recycling methodology. Feedstock cellulose and filler abound in products considered uneconomic, unsuitable for standard deinking or too weak for original product ...
A Life Cycle Energy Assessment for Biogas as Energy Carrier
(Springer International Publishing, 2023)
This chapter aims to evaluate energy flows in the life cycle of biogas utilization (i.e., production of thermal energy, cogeneration, traffic, and production of hydrogen), starting from feedstock and anaerobic digestion, ...
Experimental and theoretical consideration of the factors influencing cationic pollutants retention by seashell waste
(Wiley, Hoboken, 2018)
BACKGROUNDSeashell waste (SW) is rich in biogenic calcium carbonate and potentially can substitute geological sources in various applications, such as the separation of heavy metals and radionuclides from contaminated ...
Three-stage integration system with solid oxide fuel cell, alkali metal thermal electric converter and organic Rankine cycle for synergistic power generation
(Elsevier Ltd., 2023)
During operation, solid oxide fuel cell releases quite a great part of hydrogen energy into waste heat, leading to energy waste and even functional component degradation. In this study, solid oxide fuel cell, alkali metal ...
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 ...
