An in situ method has been developed to load Cu2O nanoparticles on the surface of a hydroxyl group rich TiO2 precursor. The as- obtained pure Cu2O nanoparticles are evenly dispersed on the TiO2 precursor surface. These nanoparticles are excellent catalyst for Ullmann type cross coupling reactions of aryl halides with phenol.

Sugar-based amphiphiles functionalized with the butterfly-like tetrabenzo[a,c,g,i] fluorene undergo stronger π–π interactions with multi-walled carbon nanotubes than amphiphiles with pyrene tails. The resulting water soluble nanoglycoarrays with a multivalent sugar exposition on their surface engage in specific ligand–lectin interactions similar to glycoconjugates on a cell membrane.

This work demonstrates the first dual application of intravenously injected SWNTs as photoluminescent agents for in vivo tumor imaging in the 1.0–1.4 μm emission region, and NIR absorbers and heaters at 808 nm for photothermal tumor elimination at the lowest injected dose (70 μg of SWNT/mouse, equivalent to 3.6 mg/kg) and lowest laser irradiation power (0.6 W/cm2) reported to date.

Graphene–CdS and graphene–ZnS quantum dot nanocomposites with CdS and ZnS homogeneously dispersed on graphene have been synthesized and unexpectedly, it was found that the graphene–CdS nanocomposite exhibits a strong positive photovoltaic response.

A distinctive Van Hove singularity observed in Pb films is responsible for the significant quantum oscillation (with a period of two monolayers) of many of the properties of films with a thickness of up to ~40 monolayers.

A highly stretchable plasmonic structure composed of a monolayer array of metal-capped colloidal spheres on an elastomeric substrate has been fabricated using simple and inexpensive self-assembly and transfer-printing techniques. This stretchable plasmonic structure offers a promising approach to tune surface plasmon resonances and might be exploited in realizing flexible plasmonic devices with tunability of mechanical strain.

We present results for the G and G+ band frequencies of all metallic (M) single-walled carbon nanotubes (SWNTs) in the diameter range from 0.8 to 3.0 nm obtained within a density-functional-based symmetry-adapted non-orthogonal tight-binding model using the optimized nanotube structure. The qualitatively different behavior of the G bands of the M SWNTs compared to that for semicon- ducting (S) SWNTs can be ascribed to the strong electron–phonon interactions in the former.
