Extraction and Structural Analysis of Sweet Potato Pectin and Characterization of Its Gel.

Pectin is widely used in the food and pharmaceutical industries. However, data on sweet potato pectin extraction and structural property analyses are lacking. Here, for the high-value utilization of agricultural processing waste, sweet potato residue, a byproduct of sweet potato starch processing, was used as raw material.

Multi-scale effects of urban agglomeration on thermal environment: A case of the Yangtze River Delta Megaregion, China.

The phenomenon of urban heat islands has been extensively investigated in recent decades. Due to the complexity of urban systems, this phenomenon may be scale-dependent, particularly for large megaregions where a cluster of cities gather together. Despite many studies focusing on urban heat islands at scales from single-site to regional, and further to global, there are few studies addressing multi-scale effects of large urban agglomeration on thermal environment.
