Quantitative Backscattered Electron Analysis Techniques for Cement -based Materials

Effective moduli for thermopiezoelectric materials with microcracks

Dilute, Self-Consistent (SC), Mori–Tanaka (MT) and differential micromechanics methods are developed for microcrack-weakened thermopiezoelectric solids. These methods are capable of determination of effective properties such as the conductivity, electroelastic moduli, thermal expansion and pyroelectric coefficients. The above material constants affected by the microcracks are derived by way of ...

Piezoresistive Cement-based Materials for Strain Sensing

Cement-based materials that exhibit piezoresistivity with sufficient magnitude and reversibility contain electrically conductive fibers. The phenomenon allows the materials to sense their own strain. The fibers are preferably discontinuous. Carbon fibers (15mm diameter) are most effective. Steel fibers (8 mm diameter) are less effective. Carbon filaments (0.1 mm diameter) are ineffective. The p...

Imaging techniques in dermatology

Since the discovery of X-rays, the use of imaging technology has continued to play an important role in medicine. Technological advancements have led to the development of various imaging modalities, most of which have been used to image organs deep within the human body. More recently, attention has focused on the application of imaging technology for evaluation of the skin. A variety of techn...
