A treatment of piperazine (H2pipz) and pyridine-2,6-dicarboxylic acid (H2pydc) with CeIII ion led to the formation of a new binuclear cerium(III) complex (H2pipz)[Ce2(pydc)4(H2O)4]·(H2O) (1). Compound 1 was characterized by elemental analyses, IR spectroscopy, thermal gravimetric and single cry...
Cerium (Ce) and cerium oxide nanoparticles (CeO2 NP) are increasingly used in different applications. Upon their release into the aquatic environment, the exposure of aquatic organisms becomes likely. In this study, the uptake of CeO2 NP and Ce3+ into the wild type and cell wall free mutant of C...
The hybrid sol-gel coatings developed in the present work serve as corrosion protection of aluminium alloy AA7075 and are based on (3-glycidyloxypropyl) trimethoxysilane (GPTMS), tetraethyl orthosilicate (TEOS) and silica (SiO2) nanoparticles, with the addition of cerium nitrate as a corrosion i...
A novel gelatin film with antibacterial activity was prepared by electrostatic crosslinking using cerium (III) nitrate hexahydrate as the crosslinking agent. The structure and properties of the films were investigated by Fourier transform infrared spectra, tensile tests, thermogravimetric analys...
The reaction mechanism and kinetics of CeO2 synthesis using a solvent-deficient method are investigated by simultaneous thermogravimetric analysis (TGA)/differential scanning calorimetry (DSC), X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM)...
A new synthesis process, laser ablation in an aqueous solution of target material, was applied to synthesize nanostructured CeO2/TiO2 catalyst particles. Reactivity within the laser plume (plasma) can be used to synthesize CeO2 from an aqueous solution, 2 M cerium (III) nitrate hexahydrate (Ce(N...
In this study, morphological, thermal and dielectric properties of chemically synthesized polyaniline (PANI) and its cerium(III)-nitrate-hexahydrate (Ce(NO3)3·6H2O) doped composites with various doping levels were investigated. Characteristic bands of emeraldine salt (ES)-form of PANI was clear...
Here we report synthesis of undoped/doped cerium(IV) pyrophosphate compounds by a new solution phase method employing cerium(III) nitrate as metal precursor and H2O2 as oxidizing agent. The phase composition and microstructure of various samples is studied and the importance of various reactants...
The objective of the present work is to assign radiation interaction parameters to the solutions of cerium (III) nitrate hexahydrate [(Ce(NO3)3.6H2O)] in different concentrations dissolved in acetone [(CH3)2CO]. The photons scattered from cylindrical aluminum target result in secondary photon be...
This study of vadose zone and aquifer sediments beneath a former dichromate spill site showed that the persistence of CrVI in the sediments and the large differences in released mass and rate was caused by the dissolution of multiple CrVI surface phases. Vadose zone sediments contained numerous ...
The shape and size of barium chromate nanoparticles formed using a water-in-oil microemulsion prepared from the anionic surfactant AOT were examined. As a result, nanowires, nanorods, and nanodots could be synthesized by changing the raw ion concentration and by adding ethanol as a poor solvent....
The evaluation of kinetic parameters and mechanism of the thermal decomposition of barium perchlorate trihydrate (BP) from non-isothermal analytical measurements using TG, DTG, and DTA have been obtained in the presence of β-MnO2 and Eu2O3. Both oxides catalyze the thermal decomposition of BP, ...
TG, DTG and DTA have been used in non-isothermal investigations of binary systems of Ni2O3 and La2O3 with barium perchlorate trihydrate, BP·3 H2O, in various molar ratios, carried out under an air (static) atmosphere from ambient to 1000°C. Ni2O3 catalysed the dehydration process of BP·3 H2O ...
