Abstract:
As one of the most advanced techniques to gain insight into the structure of the materials, wide-angle X-ray scattering (WAXS) records the scattering information at wide angles which typically larger than 5° (2θ), where contains abundant and detailed atomic-scale structure information of the matter. To improve the intensity and time-resolution, the WAXS can be further coupled with a synchrotron light source. The resultant technique, that is, Synchrotron WAXS can reach and even surpass the spatial and time resolution of 0.1 nm and microsecond scale, respectively, thus is very suitable for characterization of animal silks both statically and quasi-dynamically. This chapter would show methods to understand the structure-property relationship of animal silks by WAXS.

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
Globular and Fibrous Proteins
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
