Effect of ion implantation doping on electrical properties of yttria-stabilized zirconia thin films [PDF]

open access: yes, 1992
The change in conductivity of Fe and Ti implanted rf-sputtered layers of yttria-stabilized zirconia (YSZ) was studied as a function of the temperature (400–800°C) and oxygen partial pressure. In an oxidized state and in the temperature range of 400–600°C,

Concealed Conduction [PDF]

open access: yesCirculation Research, 1961
The existence of concealed conduction of atrial beats has been demonstrated. Concealed conduction within the atrioventricular node has been studied by recording the transmembrane potential of single nodal fibers. Conduction block in this part of the specialized conducting system depends more upon decremental conduction within certain nodal fibers than ...
