XRD Phi Rotation Scanning

X-ray diffraction (XRD) is a powerful analytical tool for industry professionals and material scientists. A source (typically copper) produces x-rays which are directed at a flat sample. These x-rays are diffracted at certain angles by the crystal planes in the material and are detected at those angles. Based on...

Heat Capacity by the Sapphire Method

The heat capacity of a material is a crucial property to consider when determining its functionality in certain applications. The typical SI unit of heat capacity (Cp) is Joules per gram Kelvin (). It is a measurement of how sensitive a material is to changes in temperature due to...

The Universal Reflectance Accessory

Many scientific applications of thin films, thermal and optical coatings, conducting oxide layers, as well as many other systems, require analysis of reflectance, absorption, and transmittance of electromagnetic radiation; specifically visible light and near-visible radiation. Here in the Materials Characterization Lab at the University of Utah, we utilize the...

Vickers Hardness testing

Hardness is defined as a material’s resistance to permanent deformation such as penetration or scratching. Static indentation tests are one way to determine hardness. For static indentation, a cone, pyramid, or ball is forced into the surface of the material. The relationship between the load applied for a given...
