Concern regarding sourcing

Source 2 has no mention of the claim made in the last sentence of Section 1.1! — Preceding unsigned comment added by 134.95.68.227 (talk) 09:35, 20 November 2018 (UTC)Reply

Seems to be OK; the second source (in the current version) is a quote from the source, under their section Graphene spotting. Klbrain (talk) 07:42, 19 August 2019 (UTC)Reply

Possible advance in cost of production (~$100 / cm^2). Please review and consider adding.

Toward Scalable Growth for Single-Crystal Graphene on Polycrystalline Metal Foil Hyeon-Sik Jang, Jae-Young Lim, Seog-Gyun Kang, Young-Min Seo, Ji-Yoon Moon, Jae-Hyun Lee, and Dongmok Whang ACS Nano Article ASAP DOI: 10.1021/acsnano.9b08305 https://doi.org/10.1021/acsnano.9b08305

"Not only is polycrystalline platinum much cheaper but they could recycle the substrate without damaging the quality of the resulting single-crystalline graphene so that it works out at around $100 dollars per cm2 of substrate instead of $2000. They expect that if they can grow the transferred seeds on polycrystalline copper or aluminum foil, they will be able to cut the costs further still."
