In meso-superstructured perovskite solar cells, the scaffolding layer, composed of insulating metal oxide nanoparticles, plays an important role in the loading efficiency of the perovskite layer. This communication describes 1D mesoporous silica nanoparticles that were successfully used as scaffolds to enhance the electron extraction from the perovskite absorber layer to the working electrode.

A new, simple method is reported to enhance the electrorheological (ER) activity of nanomaterials. Plasma treatment was the ideal technique owing to its ease of use, versatility, and common usage in mass production. Multi-gram quantities of ER nanomaterials with different morphologies, sizes, and compositions were successfully treated by ammonia plasma.

A novel strategy for designing ultrathin polypyrrole skin-coated carbon nanotube (CNT) nanohybrids is demonstrated by vapor deposition polymerization (VDP). The ultrathin skin technology provides a stable immobilization of the mono-disperse Pd nanoparticles (NPs) on the CP-CNT nanohybrid surface, leading to a high-performance hydrogen gas sensor at room temperature.

An effective approach to fabricate graphene-based conductive films is explored on the basis of the pressure-assisted reduction technique.

Polypyrrole (PPy) nanotubes have been fabricated by reverse microemulsion polymerization in an apolar solvent, and factors affecting the formation of PPy nanotubes have also been investigated.

A lamellar-structured crystalline polypyrrole (PPy) supramolecular assembly was prepared by surfactant templating, and the regularly linked amorphous PPy nanoparticles with tunable window sizes could play the role of crystalline lattices in the supramolecular assembly.

A novel approach to synthesize graphene nanosheet is explored on the basis of the layer-by-layer (LbL) self-assembly of polyallylamine (PAA) and poly(styrene-sulfonate) (PSS) multi-layer with a metallic dopant.

Titania embedded silica hollow nanospheres were synthesized from sonication-mediated etching and re-deposition of silica/titania core/shell nanospheres. The designed structure of the hollow nanospheres was proved to be a key factor for the charge trapping/detrapping and resulting bistability in non-volatile organic bistable memory devices (OBDs).

Flexible and transparent graphene films have been fabricated via inkjet printing and vapor deposition (VDP) methods, and the graphene-based acoustic actuator could be used as an extremely thin and lightweight loudspeaker.

Ferromagnetic gamma-Fe(2)O(3)/polyrhodanine nanoparticles with average diameters of ca. 10 nm were prepared by a one-step synthetic procedure and applied as a recyclable antibacterial agent towards Gram-negative/positive bacteria.

Monodisperse silica-polyaniline core-shell nanoparticles with an average diameter of 26 nm were synthesized by in-situ polymerisation of aniline monomers adsorbed on the silica surface through electrostatic interactions.

Silver nanoparticle embedded poly(vinyl alcohol)-poly(methyl methacrylate) nanofibers, ca. 30 nm in diameter and ca. 60 microm in length, were fabricated by one-step radical-mediated dispersion polymerization using 2,2'-azobis(isobutyronitrile) to reduce the silver ions. In this methodology, PVA acted both as a gelator to form the nanofibers and as a stabilizer to protect the silver clusters from sintering.

Polyimide nanotubes with tunable wall thickness were fabricated by a precursor impregnation method using an AAO template, and carbon nanotubes containing magnetic iron oxide were obtained using ferric chloride-embedded polyimide precursor by a carbonization process.

Mesoporous carbons with highly uniform and tunable mesopores were fabricated by one-step vapor deposition polymerization (VDP) using colloidal silica particles as templates and polyacrylonitrile (PAN) as a carbon precursor.
