Regularly spaced TiO2 nanotubes were prepared by anodizing a titanium substrate in triethylene glycol electrolyte at elevated temperature. In comparison to conventional TiO2 nanotubes, spaced nanotubes possess an adjustable spacing between the individual nanotubes; this allows for controlled buildup of a hierarchical nanoparticle-on-nanotube structure. Here, we use this principle for layer-by-l...

PURPOSE To identify which physical properties of nanoparticles are correlated with the survival fraction of cells exposed in vitro to low-energy protons in combination with nanoparticles. METHODS The Geant4 simulation toolkit (version 10.3) was used to model nanoparticles of different sizes (5-50 nm) and materials (Ti, Zr, Hf, Ta, Au, Pt), with or without an organic capping ensuring biocompat...

Environmental pollution and destruction on a global scale have drawn attention to the vital need for totally new environmentally friendly, clean chemical technologies and processes, the most important challenge facing chemical scientists in the field of green chemistry. Strong contenders as environmentally harmonious catalysts are photocatalysts that operate at room temperature and in a clean m...

Today surface modifications of titanium implants have become a development strategy of dental implants. The present study investigated the morphology (SEM), surface elemental analysis (EDX), surface roughness (AFM) and crystalline structure (XRD) of TiO2 film prepared via anodic oxidation of grade II commercially pure titanium specimens in different electrolytic solutions and times. Incubation ...

In the literature, few studies detailed morphometric parameters of the inferior olivary complex, and mainly applying biased methods based on counting in a two-dimensional plane. In the present work, the unbiased quantitative method of the optic disector was applied in order to analyse neuronal densities, nuclear volumes and total neuron numbers of the principal (PION), medial (MION) and dorsal ...

In this paper, graphene oxide decorated with cerium oxide (CeO2) nanoparticles was prepared and used as anticorrosive pigments in epoxy nanocomposite coatings. The synthesized nanoparticle was characterized by FTIR, XRD, SEM, and EDX analyses. Graphene oxide decorated with CeO2 nanoparticles was dispersed in epoxy resin by sonication. The optimum nanoparticle content of th...
