. These improvements are probably due to an increase in the surface roughness of polyimide (PI), the activated surface condition, and the adsorption of palladium ions/atoms (Pd) on the PI surface which act......
strength is 398MPa and the hermeticity is less than 1×10-8 Pa·m3/s. The electroless nickel was processed by utilizing palladium chloride as activator. The plating layer with bright, smooth......
for carry out related research and application. The porous titanium alloy have been developed, and the preparation methods conclude gas foaming method, organic sponge replication method, slurry foaming......
profile, reinforced with a spider web structure inside the part, supported by fibre foam structure extracted from the woodpecker sponge tissue at the centre to maximize the energy absorption capability... structure inside the part and with a multi-layer of fibre foam acting like a sponge in a woodpecker’s skull to protect its brain during a collision. In the second concept idea labelled by P2, the model......

filling method is anisotropic. The stress-strain responses of ceramic foams made by sponge-replication show isotropy and strain rate dependence. The struts brittle breaking of net structure... and ferroelectric thin films [1-4]. Open-cell ceramic foam manufacturing techniques can be classified into three general categories: sponge-replication, adding foaming agent and organic filling [5-9......
and other base metals [15], palladium and platinum [16] extraction from chloride media. Hence, it seems that gold extraction may interface with other metal species extraction. The aim of the present work...) were used for platinum, palladium, selenium and iron sources in aqueous solution, respectively. Selenium source was prepared by SeO2 dissolution in dilute hydrochloric acid solution. Analytical......
Electrochemical reduction processes The current practice of Kroll process for titanium sponge production has undergone tremendous improvements and advancements, resulting in significant improvement in energy... studied by ONO and SUZUKI[5] for preparing titanium sponge granules. The OS process, thus combines the calciothermic reduction at about 900℃ and fused salt electrolysis of CaO in CaCl2 at DC voltage......
