Application of pre-treatment for enhancing biogas production from plant-based agricultural waste
(Research and Development Center “ALFATEC”, Niš, Serbia; Complex System Research Centre, Niš, Serbia, 2018)
Agricultural waste is a suitable
renewable source for the production of biogas,
which can be converted into different forms of
energy. Chemical pre-treatment can make
anaerobic digestion faster and increase biogas
yields. ...
Assessment of spatial and temporal variations in trace element concentrations using honeybees (Apis mellifera) as bioindicators
(Peerj Inc, London, 2018)
With the increase in anthropogenic activities metal pollution is also increased and needs to be closely monitored. In this study honeybees were used as bioindicators to monitor metal pollution. Metal pollution in honeybees ...
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 ...
An artificial neural network approach for the estimation of the primary production of energy from municipal solid waste and its application to the Balkan countries
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Although the use of municipal solid waste to generate energy can decrease dependency on fossil fuels and consequently reduces greenhouse gases emissions and areas that waste occupies, in many countries municipal solid waste ...
Morphology, biocompatibility and antimicrobial activity of hydroxyapatite simultaneously doped with silver and strontium ions
(Belgrade : Serbian Academy of Sciences and Arts, 2018)
Synthesis and characterization of bioactive glass doped with lithium and strontium ions
(Belgrade : Institute of Technical Sciences of SASA, 2018)
Bioactive glasses have been used for over three decades in biomedical applications owing to high bioactivity, biocompatibility, as well as the possibility to stimulate regeneration of the bone. The aim of this work was to ...
Seam pipes for process industry - Fracture analysis by using ring-shaped specimens
(Savez hemijskih inženjera, Beograd, 2018)
Pipelines are commonly used in process industry for transport of fluids, as well as granular solids, due to their numerous advantages in comparison to other transportation means. Pipe integrity is essential for a reliable ...
Utilization of the integrated process of supercritical extraction and impregnation for incorporation of helichrysum italicum extract into corn starch xerogel
(Savez hemijskih inženjera, Beograd, 2018)
Supercritical CO2 extraction of Helichrysum italicum and impregnation of starch xerogels with the extract by using an integrated scCO(2) extraction and impregnation process were performed at 350 bar and 40 degrees C in ...
Kinetics and thermodynamics of Mo(VI) and Re(VII) sorption on amino-functionalized magnetic polymer
(Belgrade : Society of Physical Chemists of Serbia, 2018)
Kinetics and thermodynamics of Mo(VI) and Re(VII) sorption onto amino
functionalized magnetic poly(glycidyl methacrylate-co-ethylene glycol
dimethacrylate) [mPGME-deta] at 298 K and pH=4.0 were investigated. It
was shown ...
