Spectroscopy of shallow donors is a tool to test theoretical models and to reveal properties of semiconductors. In this work we consider intra-shallow impurity transitions by studying a CdTe/(Cd, Mg)Te structure grown by...

Dental caries requires remineralizing agents to restore the dentin. Mauli banana stem gel is predicted to be an alternative material for mineral deposition during the remineralization process. Fourier transform infrared ...

We investigate the electronic transport at the internal interface within a selection of metallic bilayer nanostructures using the contact-free, all-optical method of THz time-domain spectroscopy. The Ru/Co, Ru/Pt, and Ru...

By changing the temperature of chemical activation of plant biomass, nanoporous carbon materials with a specific surface area of up to 1050 m2/g were obtained. The obtained carbon materials were used to form composites w...

Water repellency related to organic matter (OM) of coatings along the earthworm burrows (EB) walls can facilitate preferential flow due to limiting the water exchange with the soil matrix. The objectives of this work wer...

Vanadium oxide thin films were fabricated using a multi-step deposition process involving magnetron sputtering and sequential annealing. The structural, vibrational, and nanomechanical properties of the films were invest...

In this paper, the adsorption of trivalent chromium cations by a sample of sodium-modified TiO2 was studied. XRF analysis of the TiO2 surface was performed.  The dependence of the adsorption value on the duration of the...

Glass ceramic samples with general composition: (2-х)Na2О : хМІ2О : 3CoО : 2P2O5 (х = 0 or  0.05, МІ – Li, K) were synthesized by melt method with subsequent annealing of homogeneous glass at a temperature o...

Background/Aim: The role of ions in prevention of dental caries has been demonstrated in numerous studies. The aim of this study was to investigate the amount of released ions from different restorative materials using i...
