TL;DR: It is reported that metamaterials consisting of period and symmetry-tunable self-assembled nanopatterns can provide a controllable refractive index medium for a broad wavelength range, including the visible region, as well as spatially graded and anisotropic refractive indices.

TL;DR: This work presents a reliable and controllable route to a highly ordered uniform Au@Ag core-shell nanoparticle array via block copolymer lithography and subsequent seeded-shell growth, and exhibits widely tunable broadband enhancement of plasmonic resonance.

TL;DR: An area-selective ultrafast nanofabrication method using low intensity infrared or visible laser irradiation to direct the self-assembly of block copolymer films into highly ordered manufacturing-relevant architectures at the scale below 12 nm is demonstrated.

TL;DR: This approach introduces diverse chemical composition of metallic elements including Au, Pt, Fe, Pd, and Co into sub-10-nm scale nanopatterns and direct the nanoscale lateral ordering of the overlaid second level BCP nanop atterns to create the superimposed multicomponents incorporating nanowires and nanodots.

TL;DR: Graphene based materials are introduced as a transferrable and disposable substrate for the self-assembled nanopatterning of nonplanar, fl exible, and even multistack device oriented structures.
