A typical washing machine contains 16 silver contacts. Silver is an excellent conductor of heat, so one of its uses is in the rear-window defrosters of cars.Ruthenium Wikipedia,Ruthenium is a chemical element with the symbol Ru and atomic number 44. It is a rare transition metal belonging to the platinum group of the periodic table.Like the other metals of the platinum group, ruthenium is inert to most other chemicals. Russian-born scientist of Baltic-German ancestry Karl Ernst Claus discovered the element in 1844 at Kazan State University and named ruthenium in
Synthesis and electrical properties of uniform silver
Silver nanoparticles are considered to apply a silver paste for electrode because of their high conductivity. However, the dispersion of silver nanoparticles in electronically conductive adhesives (ECAs) restricts them used as conductive fillers. A simple method had enabled the synthesis of silver nanoparticles by reducing silver nitrate with ethanol in the presence of poly(N-vinylpyrrolidoneHow Do You Identify Silver Ore? Reference,Silver ore can be identified in the field by evaluating the physical properties of the suspected sample or by submerging it in water. It is also identified by examining the other minerals found around the suspected ore deposit. Examining the physical properties of the suspected silver ore can lead to discerning the true identity of the mineral.
