Our primary objective was to measure root canal penetrations of aqueous antibacterial nano-chitosan (Nano-CS), for the first time. The second objective was to compare and contrast such penetrations to those of chitosan (CS) itself, as well as sodium hypochlorite (NaOCl), chlorhexidine (CHX) and ethylenediamintetraacetic acid (EDTA), at the routinely used concentrations. Molar roots were split l...

Diamond is valuable material with extraordinary high thermal conductivity and transparency in a wide spectral range from UV to IR longer wavelengths. Defects impurities the diamond lattice can absorb emit light at wavelengths specific for each of such “color centers.” Particularly, vacancy-related defects diamond, as nitrogen-vacancy (NV) or silicon-vacancy (SiV) centers, are actively investiga...

Diamond-like carbon (DLC) films have been successfully deposited on Ti-50.8 at.%Ni using plasma based ion implantation (PBII) technique. The influences of the pulsed negative bias voltage applied to the substrate from 12 kV to 40 kV on the structure, nano-indentation hardness and Young’s modulus are investigated by the X-ray photoelectron spectroscopy (XPS) and nano-indentation technique. The r...

We introduce a process for the fabrication of high-quality, spatially isolated nano-diamonds on iridium via microwave-plasma-assisted chemical vapour deposition (CVD) growth. We perform spectroscopy of single siliconvacancy (SiV) centres produced during the growth of the nano-diamonds. The colour centres exhibit extraordinary narrow zero-phonon-lines down to 0.7 nm at room temperature. Single p...

Frictional behavior of nano-undulated diamond-like carbon (DLC) films deposited by plasma assisted chemical vapor deposition (PACVD) process was investigated. In order to prepare the nano-undulated DLC film, a Si wafer with nano-sized Ni dots was prepared by rapid thermal annealing of Ni thin films. Since the structure of DLC film deposited by PACVD was independent of the substrate materials an...
