Domestic material made by calcification of modified UF resins with incorporated Fe-particles-a sensitive platform for electroanalytical quantification of gallic acid.
(University "Union Nikola Tesla", Belgrad, Serbia, 2021-09-24)
In this work, we present domestic high performance electrode material
prepared by thermolysis of in situ synthesized urea-formaldehyde (UF)
resins modified with Fe(III) nitrate. For comparison, material produced ...
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 ...
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 ...
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 ...
Thermolysis prepared Co3O4 carbon paste electrode decorated with single wall nanotubes as voltammetric sensor for determination of antioxidant α-lipoic acid
The novel carbon material modified with Co3O4 particles, prepared by calcination and mixed with single wall carbon nanotubes, was characterized and used for sensing of prominent antioxidant α- lipoic acid (LA). The new ...
The influence of different doses of γ-radiation on the hydrolytic stability of modified urea-formaldehyde (UF) resins
Zbog emisije formaldehida (СН2О) iz drvenih proizvoda, gde se urea- formaldehidne (UF) smole, izmedu ostalog, koriste za impregnaciju drvenih panela koje se koriste u unutrasnjosti stambenih i drugih objekata ...
