TL;DR: The bottom-up chemical approach of tuning the graphene sheet properties provides a path to a broad new class of graphene-based materials and their use in a variety of applications.

TL;DR: This work synthesized a porous carbon with a Brunauer-Emmett-Teller surface area, a high electrical conductivity, and a low oxygen and hydrogen content that has high values of gravimetric capacitance and energy density with organic and ionic liquid electrolytes.

TL;DR: It is shown that grain boundaries give a significant Raman 'D' peak, impede electrical transport, and induce prominent weak localization indicative of intervalley scattering in graphene, opening a route towards scalable fabrication of single-crystal graphene devices without grain boundaries.

TL;DR: In this paper, single-crystal graphene grains synthesized by ambient CVD on polycrystalline Cu are studied and individual boundaries between coalescing grains affect graphene's electronic properties.

TL;DR: Rate measurements are reported on samples in which the length of the ceria-metal interface was tailored by the use of monodisperse nickel, palladium, and platinum nanocrystals, and it is found that carbon monoxide oxidation inceria-based catalysts is greatly enhanced at the cia- metal interface sites for a range of group VIII metal catalysts.
