Methods to convert non-edible, nonpackable, and highly spoiling parts of fruits and vegetables to a nutrient-rich fine powder (flour)


In order to combat agricultural waste sustainably, this invention demonstrates how the inedible portions of fruits and vegetables can be converted to fiber, protein, and micronutrient-rich powder (flour) by using kale and collards as examples. The resulting powder (flour) is a sugar-free source of dietary fiber (50-60%), a rich source of proteins (15-25%), and mineral and vitamin micronutrients (10-15%).

High-performance protonic ceramic fuel cells manufactured by direct laser 3D printing in minutes

Advanced Materials, Sustainable Energy, Manufacturing

Compared with conventional methods, direct laser 3D printing (DL3DP) can avoid furnace firing, miniaturize the manufacturing space by one hundred times, and decrease the manufacturing time by 150 times down to minutes while only consuming 10% of processing electricity.
