Data from electrochemical impedance measurement of MgHf4P6O24 and MgZr4P6O24 solid-state electrolytes show significant improvement in the ionic conductivity ceramic electrolytes. The electrical behaviour were measured using two-probe analysis at a temperature range 182-764°C, frequency within 100 mHz to 32 MHz. In this analysis, promising bulk 4.52 x 10-4 Scm-1 7.23 10-3 achieved for electrolyt...
BACKGROUND Squeaking after ceramic-on-ceramic total hip arthroplasty is a relatively uncommon phenomenon. It usually does not require treatment in the absence of pain, mechanical symptoms, and/or relentless squeaking. The purpose of this investigation was to report on four patients who presented with hip pain and squeaking due to fractured ceramic liners after ceramic-on-ceramic total hip arthr...
