Crosslinking of Polymers: Rubber Vulcanization
(Springer Nature Switzerland AG, 2020-10-02)
Crosslinking is a process whereby the polymer segments from different polymer chains are interconnected by covalent (and sometimes ionic) linkages. Crosslinks can be formed either during the polymer synthesis process, or ...
Ternary NR/BR/SBR rubber blend nanocomposites
(SAGE, 2018-02-24)
The goal of this work was to synthesize and characterize ternary rubber blends based on polyisoprene (natural rubber (NR)), polybutadiene rubber (BR), and styrene–butadiene rubber (SBR) (NR/BR/SBR = 25/25/50) reinforced ...
Radiation stability and thermal behaviour of modified UF resin using biorenewable raw material-furfuryl alcohol
(Elsevier, 2019-06-15)
The thermal stability of organic-inorganic nano-composites prepared by a two-stage polymerization of urea-formaldehyde resin (UF) with furfuryl alcohol (FA) and TiO2 before and after irradiation has been researched. The ...
Biocomposites Based On Cellulose And Starch Modified Urea-Formaldehyde Resin: Hydrolytic, Thermal And Radiation Stability
(Wiley, 2019-04-10)
Two biocomposites based on cellulose (UFC) and starch modified urea formaldehyde (UFS) resin (F/U ratio of 0.8) were synthesized using the same procedure. The hydrolitical, thermal, and radiation stability of biocomposites ...
Radionuclides and Metals in the Parks of the City of Belgrade, Serbia: Spatial Distribution and Health Risk Assessment.
In urban areas, forest patches and parks are usually the places where people spend most of their time outdoors. Due to the poor environmental protection policy and insufficient investment in industry and energy, Serbia is ...
Review and validation of photovoltaic solar simulation tools/software based on case study
(De Gruyter, 2022-05-10)
Photovoltaic (PV) systems are an excellent solution to meet energy demand and protect the global environment in many cases. With the increasing utilization of the PV system worldwide, there is an increasing need for ...
Hydrolytic, thermal and radiation stability of modified urea-formaldehyde composites: influence of montmorillonite particle size
(Elsevier, 2022-06-15)
Urea-formaldehyde (UF) composites with a formaldehyde/urea (FA/U) ratio = 0.8 and different particle sizes of montmorillonite (MMT), namely UF/KSF and UF/K10 were synthesized. The hydrolytic stability of modified UF ...
Nano-silica-based urea-formaldehide composite with some derivates of coumarin as formaldehyde scavenger: hydrolitycal and thermal stability
(Springer Nature, 2021-01-25)
The hydrolytic stability of two nano-SiO2-based UF composites with derivates of coumarin (names as K-1 and K-2) was investigated. K-1 is 3-nitro-4-(p-tolylamino)-2H-chromen-2-one and K-2: 4-((3-nitro-2-oxo-2H-chromen-4-y ...
Elastomers based on NR/BR/SBR ternary rubber blend: morphological, mechanical and thermal properties
(Association of Chemical Engeneers of Serbia, 2019-01-24)
The elastomeric materials based on NR/BR/SBR ternary rubber blend were investigated. The polyisoprene (NR), butadiene (BR) and styrene butadiene (SBR) rubbers were used as network precursors and carbon black (CB) as an ...
Hydrolytic, thermal, and UV stability of urea-formaldehyde resin/thermally activated montmorillonite nanocomposites
(Wiley, 2020-09-16)
Urea-formaldehyde resin (F/U ratio of 0.8)/thermally activated montmorillonite (UF/ΔTK10) nanocomposite was synthesized. The hydrolytical, thermal, and UV radiation stability of UF/ΔTK10 nanocomposites are determined. UF ...
