Composite materials Prepared From Waste Eggshells And Biobased Unsaturated Polyester Resin / Kompozitni materijali na bazi otpadne ljuske jajeta i nezasićenih poliestarskih smola dobijenih iz bioobnovljivih izvora
(Belgrade : Serbian Chemical Society, 2023)
Development of biobased thermoset polymers encourages the strategic use of biobased
resources and migrating to greener technologies. Unsaturated polyester resins have an
extensive array of properties which makes them ...
The tailings from coal mine instead of waste became applicable as enzyme supports
(European Federation of Biotechnology, 2023)
Some coal mines suffer from problem of having huge deposits of bentonite that they regard as undesirable, since bentonite can cause problem due to its swelling property. Instead of piling stacks of bentonite and regarding ...
Simple One-Pot Synthesis of Fully Biobased Unsaturated Polyester Resins Based on Itaconic Acid
(American Chemical Society (ACS), 2017)
For the preparation of fully biobased unsaturated polyester resins (UPRs), the replacement of styrene with alternate nonpetroleum-based monomers turned out to be one of the most challenging tasks. Its complexity lies in ...
Development of an efficient biocatalytic system based on bacterial laccase for the oxidation of selected 1,4-dihydropyridines
(Elsevier, 2020)
Biocatalytic oxidations mediated by laccases are gaining importance due to their versatility and beneficial environmental effects. In this study, the oxidation of 1,4-dihydropyridines has been performed using three different ...
A possible connection between phosphate tungsten bronzes properties and briggs-rauscher oscillatory reaction response
(Belgrade : International Institute for the Science of Sintering (IISS), 2021)
The calcium phosphate tungsten bronze (Ca-PWB) has been synthesized and characterized (TGA, DSC, XRPD, FTIR, SEM). The influence of solid insoluble materials Ca-PWB, as well as lithium doped (Li-PWB) and cation free phosphate ...
Electric Properties of Biodegradable Copper Filled Poly(Lactide-co-Glycolide) Composites
(Zvornik, Republic of Srpska, B&H : Faculty of Technology, 2019)
The results of experimental studies of the properties of composite materials based on Poly(lactide-co-glycolide) (PLGA) matrix filled with electrolytic copper powder, having very high dendritic structure, are presented in ...
A Strategy to Revalue a Wood Waste for Simultaneous Cadmium Removal and Wastewater Disinfection
(Hindawi Limited, 2021)
In this investigation, the possibility of wood waste (hardwoods such as oaks' and alternatives' staves from Balkan cooperage) revalorization for simultaneous cadmium removal and wastewater disinfection was examined. All ...
Binary oxide ceramics for enhanced phenols degradation under simulated Solar light
(Wiley, Hoboken, 2018)
Solvothermal synthesis of ZrO2-TiO2 binary oxides and pure counterparts at 150 degrees C in water/isopropanol media is presented. Titanium (IV) isopropoxide and zirconium (IV) propoxide were used as precursors. XRD and TEM ...
Mechanical properties of composites based on unsaturated polyester resins obtained by chemical recycling of poly(ethylene terephthalate) / Mehanička svojstva kompozita na bazi nezasićenih poliestarskih smola dobijenih hemijskom reciklažom poli(etilen-tereftalata)
(Association of Chemical Engineers of Serbia, 2013)
Composites based on unsaturated polyester (UPe) resins and fumed silica AEROSIL® RY 50, NY 50, RX 50 and NAX 50, as well as graphite, TiO2 or organically modified clay CLOISITE 30B were prepared in order to investigate the ...
Reuse of waste sulfur as a binding agent in concrete
(Association for Promotion of Holistic Approach to Environment, 2018)
Mainly due to the strict global environmental regulations regarding the oil and gas
refining processes, which limit the maximum quantity of sulfur in combustibles, the
availability of waste sulfur has been considerably ...
