TL;DR: Faceted surfaces of commercially available sapphire wafers were used to guide the self-assembly of block copolymer microdomains into oriented arrays with quasi–long-range crystalline order over arbitrarily large wafer surfaces, opening a versatile route toward ultrahigh-density systems.

TL;DR: In this article, the authors investigated the thermoelectric properties of thin silicon membranes that have been decorated with high density of nanoscopic holes and showed that by reducing the pitch of the hexagonal holey pattern down to 55 nm with 35% porosity, the thermal conductivity of HS is consistently reduced by 2 orders of magnitude and approaches the amorphous limit.

TL;DR: A group IVA based nanotube heterostructure array, consisting of a high-capacity Si inner layer and a highly conductive Ge outer layer, to yield both favorable mechanics and kinetics in battery applications.

TL;DR: Differences in the nanoscopic morphologies in the bulk and thin film samples were observed arising from the competition between segmental interactions between the blocks and the substrate and the surface energies of each block.

TL;DR: In this paper, the phase behavior of block copolymers in bulk and thin films and some applications for new functional nanomaterials are described, as well as future perspectives on blockcopolymers are described.
