Halya Coynashthose targets for proton conducting membranes based on Nafion or polybenzimidazole (PBI) doped with H.PO.. In this chapter, we first briefly describe the current status of the Nafion/PTFE composite membranes and then report the PBI/PTFE composite membrane preparations, characterizations, and their a

Halya Coynash the workpiece is easy to oxidize and decarburize when heated in an unprotected atmosphere. Salt bath furnace is the use of molten salt as heating medium furnace type. Although the heating speed is fast and uniform, the oxidation and decarbonization are less, there are parts binding, clamping, and o

Halya Coynashthe need to cool the sensors with liquid helium (T =4.2 K). With the discovery of superconductivity in ceramic oxides, especially of YBa.Cu.0._. with a transition temperature of about 90 K, the expectation arose that devices based on these so-called high-T. (HTS) superconductors will quickly become
