Thermoelectric and electrical properties of triple-conducting multicomponent oxides based on substituted barium cerate-zirconate.

Multicomponent oxides often have exceptional thermal stability and interesting electronic properties. The present work presents the thermoelectric and electrical properties of the Ba(ZrHfSnTiFe)O and Ba(ZrHfSnTiCoCeBiFeYZn)O multicomponent perovskites. Single-phase cubic perovskites were synthesized using the solid-state reaction method.

The new method of ZnInS synthesis on the titania nanotubes substrate with enhanced stability and photoelectrochemical performance.

In this work, ZnInS layers were obtained on fluorine doped tin oxide (FTO) glass and TiO nanotubes (TiONT) using a hydrothermal process as photoanodes for photoelectrochemical (PEC) water splitting. Then, samples were annealed and the effect of the annealing temperature was investigated. Optimization of the deposition process and annealing of ZnInS layers made it possible to obtain an FTO-based material generating a photocurrent of 1.

Proton conductivity in multi-component ABO-type oxides.

This work investigates how configurational entropy in oxides could affect proton conductivity. For this purpose, three samples of different elemental compositions are synthesized. Five, six and seven elements were introduced into the A-site of ANbO, forming La Nd SmGd EuNbO, LaNdSmGdEuHoNbO and LaNdSmGdEuHoErNbO, respectively.

FTIR, Raman spectroscopy and HT-XRD in compatibility study between naproxen and excipients.

Detection of incompatibility between an active pharmaceutical ingredient (API) and excipients, including the selection of the most biopharmaceutical advantageous excipients is extremely important in the pre-formulation process of developing a solid dosage form technology. Therefore, having fast and reliable methods for identifying incompatibility is fundamental in pharmaceutical technology. For this purpose, combined Fourier transform infrared (FTIR) and Raman spectroscopy as well as high-temperature X-ray diffraction (HT-XRD) were used as a new approach for incompatibility detection, whereas differential scanning calorimetry (DSC) was applied as a reference method.
