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 ...
First electrochemical investigation of organophosphorus pesticide azametiphos and its quantification using electroanalytical approach
In this work, the electrochemical behaviour and the subsequent development of an analytical procedure for quantification of pesticide azamethiphos, using boron-doped diamond (BDD) electrode are reported for the first time. ...
Characterization of new syntethesized Fe2O3 nanoparticles and their application as detection signal amplifiers in herbivide bentazone electroanalytical determination
The iron oxide nanoparticles (Fe2O3 NPs) were synthesized from two different iron salts by solid-state synthesis method. The synthesized powder of Fe2O3 NPs is soluble in water, and the colloidal dispersion was characterized ...
A mini review of electroanalitical methods for pesticides quantification
This review paper shows the progress made in the last five years in electrochemical methods applied for the purpose of detection and quantification of pesticides - nowadays the most serious pollutants of the environment. ...
Boron-doped diamond electrode as efficient sensing platform for simultaneous quantification of mefenamic acid and indomethacin
Mefenamic acid and indomethacin, medicaments belonging to the group of non-steroidal anti-inflammatory agents, were determined separately and simultaneously at anodically prepared BDDE. Differential pulse voltammetry was ...
Synthesis, characterization and biological study of new dinuclear zinc(II) and nickel(II) octaaza macrocyclic complexes
Two new nitrato complexes of zinc and nickel with 1,4,8,11-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane (tpmc), have been synthesized and characterized. The IR spectral peaks showed that the coordinated and ...
