WebbDepolarized small-angle light scattering from spherulites in semicrystalline polymers gives rise to a characteristic cloverleaf pattern. For scattering from a single spherulite, the position of the maximum in scattered intensity is readily related to the spherulite radius. WebbFor more accurate results, the new special detector performs 2X better experimental speed to measure the samples with Small and Wide Angle X-Scattering at the same time. The collaboration between SCG and SLRI would demonstrate the benefits of synchrotron light source as a core value of national science and technology, leading the country to …
