Multilayer nested composite nanotube structures have been synthesized by atomic layer deposition (ALD) inside microporous Si templates. The uniformity of an array of ALD nanotubes over a large area is confirmed. The combination of nested nanotubes of insulating oxides, semiconducting materials, and metals can provide the genesis for various types of novel applications including photocatalysis, sensors and detectors, bioengineering and biomedical applications, and photovoltaic devices.

The full-scale morphologies of hen*s eggshell at different length scales are systematically investigated. Both the skeleton of calcium carbonate (CaCO3) and the pore system exhibit complex hierarchical structures. The three-level hierarchy of the pore system is highlighted and its influence on gas conduction is revealed.

Au was loaded on different supports by double impregnation (DIM), liquid-phase reductive deposition (LPRD), and ultrasonication (US), and the resulting materials tested as catalysts for CO oxidation. The best results were obtained for Au/NiO prepared by DIM, most likely due to the low Au nanoparticle size obtained (~4.8 nm).

Address correspondence to

On the WO2/W(110) surface, a C60 overlayer starts to nucleate at the substrate*s inner step edges and has a close-packed hexagonal structure. By using the WO2/W(110) surface as a preformed nanostructured template, it was shown that the ※dim§ C60 molecules follow the oxide nanorows of the substrate, occupy the grooves between them, and, as a result, are situated slightly lower than the ※bright§ C60.

CdS nanorods have been sorted by length using a density gradient ultracentrifuge rate separation method. The fractions containing longer rods showed relatively stronger oxygen-related surface trap emission, while the shorter ones had dominant band-edge emission. Inspired by these findings, different synthesis environments (N2, air and O2) have been employed in order to tailor the length distribution of CdS rods.

Density functional theory calculations of inorganic nanoribbons (BN, AlN, GaN, SiC, and ZnO) with unpassivated zigzag edges indicate that the unpassivated zigzag edges can lead to spin-splitting of energy bands, and that the inorganic nanoribbons AlN and SiC with either one or two unpassivated edges can be half metallic.
