Synthesis and characterization of copper oxide decorated zinc oxide nanorods

Lim S.K., Hong S.H., Hwang S.H., Kim H-S, Kim S., Lee D.J., Kim H-S, Kim S., DGIST(Daegu Gyeongbuk Institute of Science & Technology), KR

One-dimentional nanostructures in the form of nanorods, nanowires, nanofibers or nanotubes, appear as an exciting research area for their great potential of applications. Zinc oxide is an n-type semiconductor that has been well known for [...]

New technology for metal nanorods formation

Balucani M., University of Rome “La Sapienza”, IT

Nowadays, Novack et al. proposed a new and efficient approach for producing electricity from sun, using nanoantenna (nantenna) electromagnetic collectors with an efficiencies approaching 84%. The major technical challenge to be solved is the development [...]

Intense room-temperature photoluminescence of crystalline β-Ta2O5 nanobrick arrays

Ma Y-R, Lin J-H, Ho W-D, Devan R.S., National Dong-Hwa University, TW

In this study we analyzed the structural, electronic, and photoluminescence (PL) properties of a new morphological form, stacking Ta2O5 nanobrick arrays that were synthesized by hot filament metal-oxide vapor deposition. Field-emission scanning electron microscopy (FESEM) [...]

Fabrication of Nanoparticle Embedded Polymer Nanorod by Template Based Electrodeposition

Kang S-W, Kang W-S, Nam G-H, Kim H-S, Kim J.H., Kim K-J, Kim H-S, Kim J.H., Kim K-J, Kang S-W, Kang W-S, Kim H-S, Kim J.H., Kim K-J, Ajou University, KR

Inorganic semiconductor materials in nano-dimension have drawn intense attention in recent years because of their size-tunable optoelectronic properties arising from the quantum confinement effect. These materials often require to be incorporated into other materials, often [...]

Controlled Co-Assembly of Iron Oxide Nanoparticles and Polymers: Towards the Generation of Highly Persistent Superparamagnetic Nanorods

Fresnais J., Berret J.-F., Frka-Petesic B., Sandre O., Perzynski R., Laboratoire Matière et Systèmes Complexes, FR

In this presentation, we give an account of the formation of colloidal and supracolloidal aggregates obtained by controlled co-assembly of 7 nm particles with copolymers.

Determination of micro-structural properties with x-ray absorption fine structure

Han S.-W., Park S.H., Yu H.-J., Jeong E.-S., Kim S-H, Kim Y.J., Kim S-H, Kim Y.J., Yi G.-C., Chonbuk National University, KR

We studied the structural properties of ZnO nanostructures with x-ray absorption fine structure (XAFS) to understand the growth mechanism of vertically aligned ZnO nanorods of the average diameter of 50 - 150 nm. The orientation-dependent [...]

Novel Supramolecules Based on Architecturally Variant alpha-Cyclodextrin Polyrotaxanes and Nanorod-Like alpha-Cyclodextrin Self-Assembly

Chung J.W., Yu B.-Y., Kwak S-Y, Seoul National University, KR

Self-assembly (SA-ICs) of architecturally variant alpha-cyclodextrin (alpha-CD) inclusion complexes (ICs) formed by host-guest reaction with four polymeric guest having different molecular architectures (star-shaped, hyperbranched, diblocked, and linear polymer) and nanorod-like self-assembly (SA-CD) of alpha-CD could [...]

Towards the Preparation of Boron Carbide Nanorods by Carbothermal Reaction Method

Chang B., Gersten B.L., Szewczyk S.T., Adams J.W., Queens College, CUNY, US

Boron carbide (B4C) is an attractive material due to its extreme hardness, low specific weight, high chemical stability and good wear resistance. In this study, nano-sized boron carbide powders have been prepared through a carbothermal [...]

Molecular Dynamics Simulation of Timescale Effect and Lattice Transformation of Copper Nanorod Under Bending

Wu H.A., Wang X.X., Liu G.R., National University of Singapore, SG

Mechanical behaviors of materials and structures at nanoscale are essentially different from those at macroscale, resulting from surface effect, size effect and time scale effect. In some experimental research at nanoscale, the bending displacement of [...]
