Polypyrrole (PPy) nanotubes with highly uniform surface and tunable wall thickness were fabricated by one-step vapor deposition polymerization (VDP) using anodic aluminium oxide (AAO) template membranes, and transformed into carbon nanotubes through a carbonization process.

Water-dispersible and magneto-responsive carbon nano test tubes with a controlled length (1.3 microm) and diameter (35 nm) were synthesized by using the nanochannels of anodic aluminium oxide as a template.

Large-scale single crystalline tin nanowire arrays with preferred lattice orientation along the [100] direction were fabricated in porous anodic aluminium oxide (AAO) membranes by the electrodeposition method using copper nanorod as a second electrode.

Catalyst supports with novel chemical and physical properties are needed for producing new families of catalytic materials. The goals of this work were to demonstrate the preparation of aluminium nitride type materials and evaluate their properties as catalyst supports. To obtain aluminium nitride in high-surface-area form suitable for catalyst applications, porous silica and alumina supports w...

Recent results of CRIEPI’s pyro-process fuel cycle technology developments are reported. On the actinides deposition into liquid cadmium cathode, a series of experiments are conducted using a small scale electro-refiner of about a hundred grams actinides inventory. The suitable condition for codeposition of U and TRUs is investigated, by varying Pu/U ratio in the salt from ∞ to 1.7. The design ...

Inert-gas Arc Welding of Aluminium Aluminium is used widely in metal fabrication processes, chiefly on account of its lightness, the ease with which it may be cast, and its extreme ductility. It is also highly resistant to corrosion, owing to the formation of a protective film of oxide on the surface of the metal. This latter property, however, becomes a disadvantage when it is desired to weld ...
