The preparation of superhydrophobic surfaces on hydrophilic metal substrates depends on both surface microstructures and low surface energy. Composite electro-brush flow plating technology was developed to prepare appropriate microstructures leading to superhydrophilicity on copper surfaces. The effects of plating voltage and plating time on the coating surface structures and hydrophobicity were discussed...
The unique optical, electronic, chemical and biological properties of metal nanoparticles have stimulated a large research activity into manufacturing methods of these nano-structures. An example of copper and nickel nanoparticle synthesis using electrochemical discharges in aqueous solutions is described. This low-cost template technique is a facile procedure to fabricate large quantities of metallic...
Carbon nanotubes were prepared by using a hot filament chemical vapour deposition (HFCVD) system. Methane diluted in hydrogen was used as the reaction gas and nanosized nickel particles were used as the catalyst. Studies on the effect of catalyst preparation and growth conditions were conducted. The carbon nanotube produced under different conditions were characterized using field emission scanning...
(Ni+RuO2)/Ni active cathodes were prepared by electrochemical co-deposition of suspended RuO2 particles along with Ni2+ ions onto Ni substrates from an electrolyte solution (Watt bath). Morphology and composition of the cathodes were investigated by SEM and EDX analysis. The observations revealed the RuO 2-Ni layers covered by cauliflower-like particles which distributed homogeneously on the Ni substrate...
