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: It is shown that cobalt(II) oxide (CoO) nanoparticles can carry out overall water splitting with a solar-to-hydrogen efficiency of around 5% and that the high photocatalytic activity of the nanoparticles arises from a significant shift in the position of the band edge of the material.

TL;DR: In this paper, pyramids and platelets on a zinc-blende InAs substrate were found to exhibit a wurtzite crystal structure induced by WN nanowires.

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