Abstract The aim of the paper is a spectral study mural fresco from Serbesti wooden church, Dambovita county, partially painted, historical monument 1828 (or 1804 after some other documents). Spectral techniques as X-ray Fluorescence wavelengths dispersive (WDXRF), diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) or Raman spectroscopy, have been used in order to highlight prese...

A series of CeO2-modified Co3O4 catalysts supported over α-Al2O3 foams was prepared by solution combustion synthesis and examined for the lean methane oxidation. Two different fuels were used namely, urea glycine, with varying fuel/oxidiser (Φ) ratio. The characterised SEM-EDX, STEM-HAADF coupled to EDX mapping, ICP-AES, WDXRF, N2 physisorption, XRD, HRTEM, Raman spectroscopy, XPS, H2-TPR CH4-T...

Determination of the content chemical elements occurring in waste large, small and trace amounts was performed using two instrumental analysis techniques: ICP-OES—Inductively Coupled Plasma Optical Emission Spectrometry WDXRF—Wavelength Dispersive X-ray Fluorescence Spectrometry. Since such analyses are expensive time-consuming, objective work presented this paper development a quick inexpensiv...

The aim of this study was to examine the physico-chemical and phase characteristics ash obtained in process combustion Polish poultry manure a laboratory reactor with bubbling fluidized bed. Three experiments, differing grain size morphology raw material, method its dosing type bed, were carried out. contents main chemical components trace elements samples determined using WDXRF, composition ex...

Radhuni (Carum roxburghianum Benth.) seeds of three indigenous cultivars grown in Bangladesh have been studied for minerals and various compositional properties as well as assess their role in human nutrition. Variability was observed among investigated cultivars in terms of physical characteristics (e.g. seed volume, seed density, hydration capacity, hydration index, swelling capacity and swel...

The production of nuclear fuel used in the research reactor at Instituto de Pesquisas Energéticas e Nucleares (IPEN/CNEN-SP) requires a series of chemical and metallurgical processes. The quality of the end product depends on the control over all the stages of the manufacturing process and over the quality of raw materials employed. In fact, spectrometric methods are increasingly used as quanti...
