Dual plating for bipolar clavicle fractures: A case report

open access: yesTrauma Case Reports, 2021
Clavicular fractures are common, accounting for 4% of all adult fractures. However, simultaneous medial and lateral fractures occurring in the same clavicle (the so-called ‘bipolar clavicle fracture’) are rare.

Anticorrosion Coating of Carbon Nanotube/Polytetrafluoroethylene Composite Film on the Stainless Steel Bipolar Plate for Proton Exchange Membrane Fuel Cells [PDF]

open access: yes, 2013
Composite film of carbon nanotube (CNT) and polytetrafluoroethylene (PTFE) was formed from dispersion fluids of CNT and PTFE. The composite film showed high electrical conductivity in the range of 0.1–13 S/cm and hydrophobic nature.

Nano-Cr2N dominated films with high conductivity and strong corrosion resistance for Ti bipolar plates

open access: yesMaterials & Design, 2022
Films for bipolar plates deposited from PVD are always restricted by narrow parameters’ widow, which restrict the robust quality of high conductivity and anticorrosion due to the fluctuation of deposition plasma naturally.
