Nassdiffraction

Nassdiffraction is a term used in the field of materials science and engineering to describe the phenomenon where the diffraction pattern of a material is affected by the presence of a thin, non-crystalline layer on its surface. This layer, often referred to as a "nass" layer, can be formed through various processes such as oxidation, corrosion, or the deposition of a thin film. The nass layer can significantly alter the diffraction pattern of the underlying crystalline material, making it difficult to accurately determine its structure and properties.

The term "nassdiffraction" was coined by researchers at the University of Cambridge in the 1960s to describe this phenomenon. Since then, it has been studied extensively, and various techniques have been developed to mitigate its effects. For example, the use of thin-film deposition techniques to create a controlled nass layer can help to reduce the impact of nassdiffraction on the diffraction pattern. Additionally, the use of advanced diffraction techniques, such as synchrotron radiation and neutron diffraction, can help to overcome the challenges posed by nassdiffraction.

Nassdiffraction is an important consideration in the study of materials, as it can affect the accuracy of diffraction-based techniques used to characterize their structure and properties. By understanding and mitigating the effects of nassdiffraction, researchers can obtain more accurate and reliable data, leading to a better understanding of the behavior of materials in various applications.
