We sequenced genomes of two ureolytic bacteria, Bacillus sp. JH7 and Sporosarcina sp. HYO08, which were isolated from concrete waste and have a potential for biocementation applications.

Edge-functionalization of armchair graphene nanoribbons with pentagonal-hexagonal edge structures.

Journal of physics. Condensed matter : an Institute of Physics journal

Ryou J, Park J, Kim G, Hong S.

J Phys Condens Matter. 2017 Jun 21;29(24):245301. doi: 10.1088/1361-648X/aa6f6a. Epub 2017 Apr 26.

Using density functional theory calculations, we have studied the edge-functionalization of armchair graphene nanoribbons (AGNRs) with pentagonal-hexagonal edge structures. While the AGNRs with pentagonal-hexagonal edge structures (labeled (5,6)-AGNRs) are metallic, the edge-functionalized (5,6)-AGNRs with substitutional atoms opens a band...
