The formation of interfacial charge transfer (ICT) complexes with suitable ligands is an effective method to improve the spectral properties materials based on titanium dioxide (TiO2). In presented work, six structurally different flavonoids are studied as potential for synthesizing novel TiO2‐based ICT using density functional theory (DFT). stable bidentate Ti‐O coordination between TiO2 surface and confirmed by Bader’s quantum atoms in molecules (QTAIM) analysis. calculated band gaps...

In this study, we analysed pellets from long-eared owls (Asio otus) collected four localities in Belgrade (Serbia). The contained the remains of prey, namely voles (Arvicola terrestris) and field mice (Apodemus agrarius). concentrations 14 elements (Ca, P, Mg, Na, K, Fe, Zn, Sr, Ba, Mn, Ti, Cu, Si, B) were evaluated whole samples containing only bone tissue, which dissected pellet. increased levels certain elements, including Cu radioactive 40K, indicate contamination soil by various...

Nitrogen-doped graphene quantum dots (NGQD) were synthesized by simple and fast hydrothermal route using citric acid urea as precursors. The obtained NGQDs non-covalently functionalized (conjugated) aromatic amino acids, phenylalanine (Phe) tryptophan (Trp). Atomic force microscopy revealed that the have disk morphology with an average diameter of ~60 nm height ~0.4 nm. After conjugation, particles increased up to ~3 UV-vis spectroscopy analysis showed acids conjugated NGQD nanostructures....

Abstract Nitrogen-functionalized graphene quantum dots (N-GQDs) were synthesized by hydrothermal transformation of glycine precursors in glycerol. Functionalization GQDs with nitrogen was confirmed FTIR spectroscopy. Atomic force microscopy (AFM) analysis revealed that the thickness is around ~10 Å while lateral dimensions are range from 20 to 80 nm. N-GQDs exhibit strong fluorescence blue (420 nm) region and they suitable for bioimaging applications.
