TL;DR: Transparent, conductive, and ultrathin graphene films, as an alternative to the ubiquitously employed metal oxides window electrodes for solid-state dye-sensitized solar cells, are demonstrated and show high chemical and thermal stabilities and an ultrasmooth surface with tunable wettability.

TL;DR: Cai et al. as discussed by the authors used a surface-assisted coupling of the precursors into linear polyphenylenes and their subsequent cyclodehydrogenation to produce GNRs of different topologies and widths.

TL;DR: Self-organization of liquid crystalline and crystalline-conjugated materials has been used to create, directly from solution, thin films with structures optimized for use in photodiodes, demonstrating that complex structures can be engineered from novel materials by means of simple solution-processing steps and may enable inexpensive, high-performance, thin-film photovoltaic technology.

TL;DR: It is found that Fe(3)O(4)/N-GAs show a more positive onset potential, higher cathodic density, lower H(2)O-2) yield, and higher electron transfer number for the ORR in alkaline media than Fe( 3)O (4) NPs supported on N-doped carbon black or N- doped graphene sheets, highlighting the importance of the 3D macropores and high specific surface area of the GA support for
