Fretting corrosion of screws contribute to the fixation failure of the femoral neck: a case report
Biosurface and Biotribology, Volume 5, Issue 4, Page 118-123, December 2019., 2019 Fretting corrosion of metal implants has been associated with implant failure and revision surgeries. This report describes the fixation failure of a femoral neck fracture in a 61‐year‐old male patient due to corrosion of three cannulated screws. Radiographic evaluation at the time of primary surgery demonstrated well‐positioning of the cannulated ...

IET Nanodielectrics, Volume 2, Issue 4, Page 129-134, December 2019., 2019 The effective permittivity of low‐density polyethylene with the conductive carbon black (CB) was modelled by COMSOL. The impact of CB content on the electric properties of the composites with different geometry of the inclusions was investigated. The modelling outcomes evidenced that the simulation was in good agreement with the experiment results at ...

Improved dielectric properties achieved by blending PP and PVDF
IET Nanodielectrics, Volume 2, Issue 2, Page 78-81, June 2019., 2019 Polymer films composed of polypropylene (PP) and poly(vinylidene fluoride) (PVDF) have been fabricated by extrusion with filming system. Owing to the low content of crystallites and the lubricant of carbon black, the commercial product PVDF 370 can be compatible with PP by simply blending at the molten state and the obtained film has improved ...

Frequency tunable graphene metamaterial reflectarray for terahertz applications
The Journal of Engineering, Volume 2018, Issue 9, Page 753-761, September 2018., 2018 A graphene‐based metamaterial (GMM) reflectarray antenna with frequency tunable radiation characteristics has been investigated in this study. The unit‐cell element consists of graphene split‐ring‐resonator (SRR) with two gaps printed on a grounded SiO2 substrate. The electrical properties of the metamaterial unit‐cell have been determined at different

Terahertz band communication using plasma wave propagation in multilayer graphene heterostructures
IET Cyber-Physical Systems: Theory &Applications, Volume 3, Issue 2, Page 89-98, June 2018., 2018 Graphene‐based heterostructures provide a viable platform to implement optoelectronic devices that can operate in the terahertz (THz) band. In this study, the authors focus on multilayer (ML) graphene as the building block to implement high‐frequency and low‐energy plasmonic interconnects for on‐chip signalling in next‐generation systems.

High Voltage, Volume 2, Issue 1, Page 32-38, March 2017., 2017 High dielectric loss has been the biggest sticky problem for high‐k conductor/polymer composites. Herein, a new asymmetric material consisting of one layer of β‐phase poly(vinylidene fluoride) (PVDF) and another layer of carboxylated carbon nanotube (eCNT)/cyanate ester (CE) composite was fabricated, coded as PVDFx–eCNTq/CE, where x is the thickness of

Flexible capacitive pressure sensor based on multi‐walled carbon nanotube electrodes
Micro &Nano Letters, Volume 12, Issue 1, Page 45-48, January 2017., 2017 Flexible pressure sensors offer the advantages of flexibility, low cost, and easy to large area fabrication, and they have wide applications in many fields. This work proposes a flexible capacitive pressure sensor that exhibits a sandwich‐like structure, a good performance, and a simple process.
