Stability of waste-based zeolite supported CaO catalyst for biodiesel production from waste oily feedstocks
(Fuel Science Center, 2021)
Waste-based zeolite supported CaO catalyst (20CaO/ZMFA) was synthesized by ultrasound-assisted impregnation from alcoholic suspension. Zeolite was previously synthesized from lignite coal fly ash (FA) by alkali activation ...
Fractal Reconstruction of Fiber-reinforced Epoxy Microstructure
(Institute of Electrical and Electronics Engineers Inc., 2021)
In the past century, the use of polymers and composites with a polymer matrix has expanded to such a level that today it is impossible to imagine life without these materials. Epoxy resin and epoxy-based composites are ...
Electrodeposition of Nd and Pr onto W from fluoride based melts / Elektrohemijsko taloženje Nd i Pr na W iz fluoridnih rastopa
(Belgrade : Serbian Society of Corrosion and Materials Protection (UISKOZAM), 2021)
Electrodeposition of neodymium and praseodymium metal from molten NdF3+PrF3+LiF+ 0.5wt.%Pr6O11+0.5wt.%Nd2O3 electrolytes on W was investigated using voltammetry at 1050 °C. The square wave voltammetry confirmed that Nd ...

Research on micronutrients in the milk of mothers of premature infants
(Serbian Nutrition Society, 2021)
Every year about 4.000 babies are born prematurely in Serbia. Adequate nutrition of premature infants is very important for their health and appropriate development. Although human milk (HM) contains significant biomolecules ...
Electrochemical properties of pigment extracts from dark red corn grains / Elektrohemijska svojstva ekstrakata pigmenta iz zrna kukuruza tamnocrvene boje
(Belgrade : Serbian Society of Corrosion and Materials Protection UISKOZAM, 2021)
Electrochemical properties of pigment extracts from dark red corn grains was investigated by means of cyclic voltammetry (CV) and square wave voltammetry (SWV) on glassy carbon electrode (GC) in 0.1 M H2SO4. The shape of ...
Chemical caracterization and investigation of biological activities of frangula alnus ethylacetate extract
(Opole, Poland : University of Opole, 2021)
The aim of the study was to chemically characterize the ethyl-acetate extract of F. alnus bark and investigate its antioxidant and antibacterial potential. Qualitative analysis of extract was done by GCxGC-MS while selected ...
Microorganisms as key links in the flow of substances and energy in ecospheres
(Udruženje mikrobiologa Srbije, 2021)
The most energy on Earth derives from radiant energy of the sun, which is transformed into chemical and mechanical
energy. Energy links species, and flows through ecosystems because changing the energy available at one ...
Decolorisation of the textile dye using microbial fuel cells as an electricity source
(Japan Society for Environmental Chemistry, 2021)
Microbial fuel cells are increasingly used as alternative energy sources. The amount of electricity produced by MFC systems is sufficient to run systems that do not require high energy consumption, such as electrochemical ...
