Abstract To improve electrical conductivity of the carbon-based pantograph strip, a sliding contact material of pyrolytic carbon (PyC) coated-copper foam/carbon composite was fabricated by chemical vapor deposition technology, followed by densifying processes of furan resin impregnation and carbonization. Morphology, electrical conductivity, wear and friction behavior of the composites are investigated to clarify the effect of PyC thickness (from 0 μm to 280 μm) on tribological behaviors and current transfer characteristic. The results show that there is a good interface combination between...

Abstract Oxygen (O) functionalized carbon materials can provide high charge storage because of their enrichment in redox-active sites, but they do not display fast charge transfer kinetics, which is caused by the loss of electrical conductivity from the disruption of sp carbon networks. To address this challenge, we develop a novel two-step protonic acid catalysis method that partially re-establishes a π-π conjugated system for engineering fast electronic transport channels in an O-functionalized carbon textile. This method largely maintains the sp carbon network integrity with abundant a...

Major Turkish berry grower benefits from multi-parameter soil measurements The Turkish company SBR Agricultural Products (SBR) was founded in 1990 and operates in the Mersin Silifke region of Turkey. It specialises in the cultivation of fruit, especially berries – using cutting edge techniques. Its growing facilities are substantial – with 400,000 square metres of hydroponic strawberry greenhouses, and separate 50,000 square meter production areas for raspberry, blackberry and blueberry. SBR staff have been using the Delta-T Devices WET Kit since 2018 to help manage their hydroponic stra...
