X-ray diffraction analysis for dna helix patterns paper instructions: the paper will discuss the topic in detail as it pertains to the criminal justice profession and its integration with the forensic sciences since forensic science evaluations are rooted in honesty and integrity, your paper will integrate how the topic relates to the saint leo core. X-ray powder diffraction (xrd) is a rapid analytical technique primarily used for phase identification of a crystalline material and can provide information on unit cell dimensions the analyzed material is finely ground, homogenized, and average bulk composition is determined. Several factors includes shape, orientation, stress, strain, that influence the broadening, the intensity and the position of diffraction peaks. Nano-technology research and x-ray analysis is applied to the understanding of characteristics of nano-materials and nanostructure of crystalline materials, semi-crystalline materials and amorphous materials in industries such as glass and polymers, and requires specialist understanding and interpretation of results.
