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 羽每羽 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每lectin interactions similar to glycoconjugates on a cell membrane.

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每phonon interactions in the former.
