Direct Ni Electroless Metallization of Poly(etherimide) without Using Palladium as a Catalyst Mariène Charbonnier1,Yves Goepfert2,Maurice Romand1 (1.Laboratoire de Sciences et Ingenierie des... electroless metallization of polymers needs the grafting of a catalyst (palladium in the Pd(0) oxidation state) on the substrate surface to be coated. Our previous works on this topic [1-5] have......
Mechanical, electrical, and thermal expansion properties of carbon nanotube-based silver and silver–palladium alloy compositesHemant Pal1,2摘 要:The mechanical, electrical, and thermal expansion properties of carbon nanotube(CNT)-based silver and silver–palladium(10:1, w/w) alloy nanocomposites are reported. To tailor the properties of silver, CNTs were......
junction (TJ) containing a twin boundary (TB) in nanocrystalline palladium has been observed along the common axis direction.Molecular statics calculation and imaging simulation were performed......
sponge cadmium" was inhibited. The analysis of the cyclic voltammetry and linear sweep voltammetry diagrams showed that ultrasonic waves can promote and accelerate the replacement reaction, decrease... electrically enhanced replacement reactions and decrease the electric potential requirement. Key words: cadmium; electrically enhanced cementation; ultrasonic; electrochemical mechanism; floating sponge......
