Journal ArticleDOI
Morphology-controllable synthesis of cobalt oxalates and their conversion to mesoporous Co3O4 nanostructures for application in supercapacitors.
TL;DR: Electrochemical experiments reveal that the layered parallel folding structure of mesoporous Co(3)O(4) nanostructures are promising electrode materials for supercapacitors and the specific capacitance decay after 1000 continuous charge-discharge cycles was negligible, revealing the excellent stability of the electrode.
Journal ArticleDOI
The effect of particle size of nanometer ZrO2 on the tribological behaviour of PEEK
TL;DR: In this article, the performance of polyetheretherketone (PEEK) filled with nanometer ZrO 2 was investigated under ambient conditions on a block-on-ring machine by running the PEEK composite block against a plain carbon steel ring.
Journal ArticleDOI
The friction and wear properties of nanometre SiO2 filled polyetheretherketone
TL;DR: In this article, the wear traces and the transfer film were observed by scanning electron microscopy (SEM) and it was inferred that the transferred film contributed largely to the decreased friction coefficient and wear rate of the filled PEEK composites.
Journal ArticleDOI
An investigation of the friction and wear properties of nanometer Si3N4 filled PEEK
TL;DR: In this article, a block-on-ring machine was used to run a polyetheretherketone (PEEK) composite block against a plain carbon steel (AISI 1045 steel) ring and the morphologies of the wear traces and transfer film were observed by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS).
Journal ArticleDOI
Dual-Triggered and Thermally Reconfigurable Shape Memory Graphene-Vitrimer Composites.
TL;DR: Graphene serves as energy convertor to convert near-infrared (NIR) irradiation into thermal energy to induce a helix shape sample that is recovered totally within 80 s sequent NIR irradiation.
