The use of lubricants (solid or liquid) is a well-known and suitable approach to reduce friction wear moving machine components. Another possibility influence the tribological behaviour formation well-defined surface topographies such as dimples, bumps lattice-like pattern geometries by laser texturing. However, both methods are limited in their effect: textures may be gradually destroyed plastic deformation removed from contact area, therefore no longer properly protecting contacting...
Abstract The main drawbacks of cardiovascular bare‐metal stents (BMS) are in‐stent restenosis and stent thrombosis as a result an incomplete endothelialization after implantation. Nano‐ microscale modification implant surfaces is strategy to recover the functionality artery by stimulating guiding molecular biological processes at implant/tissue interface. In this study, cobalt‐chromium (CoCr) alloy modified via direct laser interference patterning (DLIP) in order create linear onto CoCr with...
Nickel composites reinforced with multiwalled carbon nanotubes (MWCNT) are manufactured via hot pressing. The precursor blends processed by a colloidal mixing method, which mixes the Ni dispersion of MWCNT in ultrasound. structure MWCNTs is evaluated Raman spectroscopy order to assess defect situation, observing that despite increasing amount defects, retain their structure. After sintering, interfacial interactions between and studied different approaches. sintering analyzed situ high...
The transition toward an electricity‐driven world is testing electrical contact materials to their limits. Specifically, new alternatives are needed where composites that sacrificed conductivity in exchange for reduced weldability and higher heat dissipation sufficed. Carbon nanotubes (CNT) have the potential close gap as ideal fillers due outstanding intrinsic properties, pushing application limits further. However, reported measurements show no clear tendency. In present study, authors...
Endothelial coverage of an exposed cardiovascular stent surface leads to the occurrence restenosis and late-stent thrombosis several months after implantation. To overcome this difficulty, modification surfaces with topographical or biochemical features may be performed increase endothelial cells' (ECs) adhesion and/or migration. This work combines both strategies on cobalt-chromium (CoCr) alloy studies potential synergistic effect linear patterned that are obtained by direct laser...
From waste to single-wall carbon nanotubes and silica nanowires: the first high-tech outlet for FC3R.
The decoration of carbon nanotubes with metallic nanoparticles has been extensively studied for different systems. Despite the fact that several routes are available production these heterostructures, their complexity and large amount reagents severely hinder applicability. In this study, we propose an alternative route based on ultrasonic assisted polyol reduction, which requires lower temperatures when compared to traditional methodologies. Furthermore, used solvent (ethylene glycol) is...
