- Influence of YH2 Nanoparticles Addition on the Microstructure and Mechanical Properties of Oxide Dispersion Strengthened Ferritic Alloys
Tong Liu, Chenxi Wang, Hailong Shen, Yurong Cao and Wusheng Chou
Article first published online: 19 SEP 2014 | DOI: 10.1002/adem.201400299
YH2 nanoparticles are used as raw particles to substitute the conventional Y2O3 nanoparticles in the Al-containing ODS steels. Y2Ti2O7 nanoparticles in coherent with α-Fe matrix are generated and the mean size of the oxide particles is successfully decreased. The tensile strength of the ODS steel increases with the addition of YH2.

A novel way for destruction-free, volume-oriented component diagnostics is reported. Surface-modified magnetic nanoparticles are applied for impregnation of plasma-activated UHMW PE textiles, which are embedded into an epoxy matrix. Supported by simulations, this comprehensive study from single molecules to composites extends the knowledge of molecular interactions at polymer interfaces and broadens the application of non-destructive methods.
- Self-Catalytic Growth of β-Ga2O3 Nanostructures by Chemical Vapor Deposition

Self catalytic growth of beta-gallium oxide (β-Ga2O3) nanostructures has been reported. The detail structural, morphological and optical analyses of as-grown nanostructures are carried out using various techniques such as X-ray diffraction, scanning electron microscopy, high resolution transmission electron microscopy, Raman and cathodoluminescence. The as-grown nanostructures are monoclinic and single crystalline with excellent optical properties.
- Purification of Carbon Nanotube Sheets

Purification of carbon nanotube macroscopic assemblages such as sheets presents additional challenges in comparison to that established for powdery carbon nanotubes. It is demonstrated that large-sized carbon nanotube sheets can be effectively purified to remove residual metal catalysts while retaining their structural integrity and mechanical properties for their use in structural composites.
