By introducing pentagons and heptagons into pristine carbon nanotubes (CNTs), various curved carbon nanostructures can be formed due to change of curvature. Here, zero-dimensional toroidal CNTs, and one-dimensional kinked and coiled CNTs are reviewed, covering their unique geometries, novel properties and specific applications.

Europium-doped gadolinium oxide (Gd2O3:Eu) nanoparticles conjugated with AS1411 aptamer (A-GdO:Eu) present strong fluorescence in the visible range, high magnetic susceptibility, X-ray attenuation and good biocompatibility and can be employed in fluorescence, magnetic resonance and computed tomography molecular imaging.

We present a facile method for producing superhydrophobic nanograss-coated (SNGC) glass surfaces that possess both reduced reflectivity and self-cleaning properties at the air/glass interface. Using the SNGC glass, we demonstrate superhydrophobic and antireflective organic photovoltaic cells with improved power conversion efficiency.

Porphyrin nanoaggregated layers are used to induce large work function shift on organic semiconductors. Significant enhancement in the efficiencies of organic light emitting diodes and organic photovoltaics was observed after the insertion at the cathode interface of a layer consisting of the porphyrin 1 having its molecules arranged with a face-to-face orientation.

The field effect transistors and photodetectors of two-dimensional GaTe nanosheets have been demonstrated. Photodetectors based on 2D GaTe with a direct bandgap show broad spectral response and ultrahigh photoresponsivity and detectivity.

High densities of magnetic nanoparticles with a narrow size distribution anchored on graphene have been synthesized by atomic layer deposition. The composites exhibit remarkably improved electromagnetic absorption properties with lower filling ratio and coating thickness compared with pristine graphene and other recently reported materials.

Highly conductive PEDOT:PSS/graphene composites were directly synthesized by in situ polymerization. The electrical conductivity of the composite film was enhanced by 40.6%, reaching 637 S·cm−1 by introduction of 3 wt% graphene without any further complex reduction processes of graphene.

Small Ag clusters confined in the channels of ordered mesoporous anatase TiO2 have been fabricated via a vacuum-assisted wetimpregnation method and shown to exhibit excellent solar-lightdriven photocatalytic performance, owing to the synergistic effects between small Ag clusters acting as traps to effectively capture the photogenerated electrons, and the surface plasmon resonance.

Chemical vapor deposition (CVD) graphene has been nanopatterned using a spherical block copolymer etch mask and tested as a NO2 supersensitive sensor. The nanopatterned graphene devices open a new way for scalable fabrication of NO2 sensors with more than one order of magnitude higher response than CVD graphene in the sub-100 ppb range.
