Architecture of graphdiyne nanoscale films

TL;DR: The fundamental relationships between electronic structure, adsorption energy, and apparent activity for a wide variety of 2D electrocatalysts are described with the goal of providing a better understanding of these emerging nanomaterials at the atomic level.

TL;DR: The recent development of this concept is reviewed here and a novel principle for the design of oxygen electrocatalysts is proposed and an overview of the defects in carbon-based, metal-free electrocatalysis for ORR and various defects in metal oxides/selenides for OER is provided.

TL;DR: One of these materials, 6,6,12-graphyne, does not have hexagonal symmetry and features two self-doped nonequivalent distorted Dirac cones suggesting electronic properties even more amazing than that of graphene.

TL;DR: A state-of-the-art research into graphdiynes and graphynes is summarized, with a focus on the latest theoretical and experimental results.

TL;DR: Iijima et al. as mentioned in this paper reported the preparation of a new type of finite carbon structure consisting of needle-like tubes, which were produced using an arc-discharge evaporation method similar to that used for fullerene synthesis.

TL;DR: This work shows that graphene's electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers, and allows unambiguous, high-throughput, nondestructive identification of graphene layers, which is critically lacking in this emerging research area.

TL;DR: In this article, the authors proposed a truncated icosahedron, a polygon with 60 vertices and 32 faces, 12 of which are pentagonal and 20 hexagonal.

TL;DR: Raman spectra are reported from single crystals of graphite and other graphite materials as mentioned in this paper, and the Raman intensity of this band is inversely proportional to the crystallite size and is caused by a breakdown of the k-selection rule.
