Some Applications of AC Impedance Spectroscopy in Cement Research

Freezing of water in portland cement paste - an ac impedance spectroscopy study

The freezing of water in Portland cement paste was investigated using a.c. impedance spectroscopy techniques. Length change and impedance measurements on cooling and warming were obtained simultaneously using a specially designed coupling technique. A new descriptor of frost resistance is described in terms of the high frequency arc depression angle in the impedance plane. Curves of the depress...

Applications of Electrical Impedance Tomography in Neurology

Introduction: Electrical impedance tomography (EIT) is a non-invasive technique utilized in various medical applications, including brain imaging and other neurological diseases. Recognizing the physiological and anatomical characteristics of organs based on their electrical properties is one of the main applications of EIT, as each variety of tissue structure has its own electrical characteris...
