Influence of surface layer on mechanical and corrosion properties of nickel-titanium orthodontic wires.

Conclusion: Working properties of NiTi wires were unaffected by various coatings in unloading. Nitrification improved corrosion resistance. Rhodium coating reduced corrosion resistance and pronounced susceptibility to pitting corrosion in artificial saliva because of galvanic coupling between the noble coating and the base alloy.

The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscope (HRTEM), X-ray photoelectron spectroscopy (XPS), Raman, electron spin-resonance (ESR) and surface photovoltage spectroscopy (SPS). The results reveal that SCFs c...

In this study, mechanical, histochemical and molecular assays were conducted to understand the mechanisms underlying the effects of Ca in fruit physical properties. In a two-year field trial, grapevines were sprayed with exogenous CaCl2 throughout the fruiting season. Results showed an increase in berry Ca concentration at harvest, associated to increased fruit consistency and skin resistance. Scanning electron microscopy showed that fruits from Ca-treated plants had smoother skin surfaces than control fruits, and that microcracks encircling the lenticels were less prominent. Histochemistry assays suggested higher depositi...

Powders of shells species (Dosinia exoleta and Ostrea edulis), with particle size fractions of 0.045 – 0.125 mm, 0.125 – 0.2 mm, and 0.2 – 1 mm, were subjected to degradation at the various heating rates (5, 10, 15 and 20&th...

ConclusionThis initial study found that DCE-MRI CoV was independently associated with malignancy in patients with suspected lung cancer. CoV has the potential to help diagnose indeterminate pulmonary lesions and may complement TIC-derived DCE-MRI metrics. Further studies are warranted to validate the diagnostic value of DCE-MRI intensity histogram analysis.
