The power of graphene in sportswear

G+ comprises pristine graphene nanoplatelets and its inclusion in fabric promotes temperature regulation for the wearer. Traditionally, textile development focuses on through-plane properties of fabric that regulate the relationship between the human body and the environment, such as textile breathability or impermeability, a Directa Plus spokesman says.

Directa Plus pioneers graphene use as sector evolves –

Directa Plus is also part of a €1mln EU-sponsored initiative to develop a digital printing method for textiles using graphene. Transport, oil and gas Directa is working with Marangoni – one of Italy's leading re-tread companies – to produce better performing tyres for commercial buses and lorries.

Graphene nanoplatelets as a solid phase extraction

Graphene nanoplatelets are a novel class of carbon nanostructures. They possess an ultra high surface area, and thus have great potentials for the use as sorbent materials. We herein demonstrate the use of graphene nanoplatelets as an adsorbent material for solid-phase extraction. Surface compositions of graphene nanoplatelets were examined by X-ray photoelectron spectroscopy. Scanning
