In electronics, solders are main material to connect electrical components to substrates which are generally printed circuit boards. Although they are cheap, they are not effective if long term performance is considered since solders have low resistivity to corrosion relatively. Since corrosion reduce reliability, the cost of advanced technological systems such as RADAR, SONAR, LIDAR and more increase. In addition, small signals can be lost, and in huge data transfer, some of the data can be lost also especially which may lead catastrophic failures in critical systems. For instance, surface to air missiles can be launched to target which is not exist if the data coming from detection systems is noisy. Therefore, corrosion protection is necessary, and  silver conductive adhesive paste  is an essential candidate to replace PbSn solders due to its resistivity to corrosion. Silver conductive adhesive paste provide not only noisy reduction but also electromagnetic interference whi...

- Tantalum is a chemical element with symbol Ta and atomic number 73. - Tantalum is part of the refractory metals group, which are widely used as minor components in alloys. - Tantalum is dark (blue-gray),dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity. - Tantalum is a shiny, silvery metal which is soft when is pure. - Tantalum is almost immune to chemical attack at temperatures below 150 C. - Tantalum is virtually resistant to corrosion due to an oxide film on its surface. - Tantalum finds use in four areas: high-temperature applications, such as aircraft engines; electrical devices, such as capacitors; sirurgical impants and handling corrosive chemicals. - Because tantalum oxide is very insoluble, there is almost no tantalum to be found in natural waters. - Tantalum has no known biological role. It is non-toxic. - Tantalum has a melting point exceeded only by tungsten and rhenium. Posted by Direniş ÇA...

Studies in the Center of Multidimensional Carbon Materials (CMCM), within the Institute for Basic Science (IBS) have shown protection of glass from corrosion by graphene coating. Glass is a most common packaging material for protection of medicine and chemicals due to its high degree of resistivity towards corrosion and chemicals. However, some glass types can corrode over time at high humidity and pH conditions which will cause to decrease in its transparency and strength. Therefore, silicate glass corrosion under high humidity is a most serious problem especially for pharmaceutical, environmental and optical industries in hot and humid climates. With the adsorption of water on the glass surface, hydrogen ions of water diffuse into glass and exchange with the sodium ions present in the glass surface. Then, pH of the water near the glass surface increases leading to dissolving of silicate structure...
