Figure 3
Two images side by side display granules labeled as PLA mSCG5 and PLASCG5, showcasing similar shapes and textures, placed against a white background.The image features two separate close-up photos of granules with visible surface textures and shapes. On the left is a mound of granules identified as PLA mSCG5, while the right shows granules labeled PLASCG5. Both mounds are composed of similarly sized, cubic granules arranged in a somewhat disordered heap against a plain white background. The images are aligned side by side for comparison, allowing for visual distinction between the two sample types.
