“…Yttriastabilized tetragonal zirconia polycrystals (Y-TZP) are now commonly used, achieving good long-term prognosis as an artificial joint material in medical disciplines 4) . Y-TZP has superior biocompatibility because it shows little elution of metal ions 5) . Furthermore, it has high bending strength, high toughness and excellent operability when compared with alumina 6) .…”

The aim of this study was to assess hard and soft tissue responses using three dental implants made of different materials. Implants made of titanium (Ti), yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) and ceria partially stabilized zirconia/alumina nanocomposite (Ce-TZP/Al2O3) were used in a dog model. Five male beagles were sacrificed at three months after implantation, and harvested mandible were observed and analyzed. Histological observations were similar in all groups. There were no significant differences in any histomorphometric parameters. Our results suggested the possibility of Ce-TZP/Al2O3 as a dental implant material, similar to Ti and Y-TZP.

“…Among the numerous separation schemes that have been published, we chose the methods of Bandi et al . () for the separation of Ti, Nb and Ta and that of Strelow and Bothma () for the separation of Hf and Zr. The details of the adopted protocols can be found in the electronic supplementary information file.…”

A voltammetric method for the determination of the high field‐strength elements Ti, Zr, Hf, Nb and Ta by adsorptive stripping of their tartrate complexes is presented. The applicability of the method to geological and metallurgical samples is illustrated by the analysis of certified reference materials (USGS BCR‐2 basalt, BCS‐CRM 388 zircon and Euronorm CRM 579‐1 ferroniobium). Suitable sample preparation techniques, involving fusion with LiBO2 and acidic and basic fluxes, followed by preliminary separation by anion chromatography are described. The method is rapid, affordable and environmentally friendly as it does not require problematic compounds such as hydrofluoric acid or toxic solvents and represents an alternative to more commonly used methods (AAS, ICP‐OES, ICP‐MS).

“…Alternatively, the presence of redox-sensitive Fe or other major elements may change the valence of Mo, resulting in the persistence of mixed valence states in the primary column. One way to mitigate this possible effect is to load the column using H 2 O 2 or another oxidizing agent to better control the oxidation state of Mo (and Fe) (e.g., Bandi et al, 1961), but this is yet to be incorporated into methods described here.…”

Procedures for the separation, purification, and high-precision analysis of mass independent isotopic variations in Mo using negative thermal ionization mass spectrometry are reported. Separation and purification of Mo from silicate and metal matrices is achieved using a two-stage anion exchange chromatographic procedure. Molybdenum is ionized as the MoO 3 species using a double filament assembly. The MoO 3 ion beams are collected using Faraday cup detectors equipped with a mixed array of amplifiers utilizing 10 11 and 10 12 Ω resistors, which allows for in situ measurement and correction of oxygen isobars. The long-term external reproducibility of 97 Mo/ 96 Mo, the most precisely measured Mo isotope ratio, is ± 5.4 ppm (2SD), based on the repeated analyses of the Alfa Aesar Specpure® Mo plasma standard and using 98 Mo/ 96 Mo for fractionation correction. The long-term external reproducibilities of
