Study of polypropylene surface modification by air dielectric barrier discharge operated at two different frequencies
(2012-10-18)
In this work, air dielectric barrier discharge (DBD) operating at the line frequency (60 Hz) or at frequency of 17 kHz was used to improve the wetting properties of polypropylene (PP). The changes in the surface hydrophilicity ...

Comprehensive Characterization of Titania Nanotubes Fabricated on Ti-Nb Alloys: Surface Topography, Structure, Physicomechanical Behavior, and a Cell Culture Assay
(Amer Chemical Soc, 2020-03-01)
In this study, hybrid composites based on beta-alloy Ti-xNb and oxide nanotubes (NTs) have been successfully prepared. NTs of different sizes were grown on Ti-Nb substrates with different Nb contents (5, 25, and 50 wt %) ...
Different surface treatment strategies on etchable CAD-CAM materials: Part 1—Effect on the surface morphology
(2022-01-01)
Statement of problem: Polymer-based computer-aided design and computer-aided manufacturing (CAD-CAM) materials have either a high content of ceramic filler particles or a ceramic network structure. Proper etching of these ...
