This invention discloses a gas-liquid split-flow micro / nano porous electrode device, comprising a U-shaped hollow substrate and a multi-level micro / nano pore directional flow channel system disposed on its wall. The directional flow channel system is divided into a nitrogen transport channel group on the inner wall side and an electrolyte transport channel group on the outer wall side. Both groups of channels are composed of several micropore arrays arranged in a staggered manner along the substrate wall thickness direction. The nitrogen transport channel group adopts a gradually expanding structure, allowing nitrogen to enter from the small-diameter end on the N2 main inlet pressure stabilizing chamber side and exit from the large-diameter end on the inner wall catalyst layer side, achieving directional enrichment and efficient transport of nitrogen. The electrolyte transport channel group adopts a gradually contracting structure, allowing the electrolyte to enter from the large-diameter end on the external environment side and exit from the small-diameter end on the inner wall catalyst layer side, suppressing excessive proton transport to the catalyst layer interface. This invention, through spatial isolation and independent control, simultaneously solves the problems of limited nitrogen mass transfer and severe hydrogen evolution side reactions in traditional electrodes, significantly improving ammonia yield and Faraday efficiency.

This invention discloses a time-release, slow-release, blood sugar-controlled compound cereal nutritional powder, its preparation method, and its applications, belonging to the field of functional cereal food technology. It comprises: 10-15 parts of fast-phase particles, 35-45 parts of slow-phase gradient-degrading gel microspheres, and 30-40 parts of complementary-phase particles; each is an independent particle form, and after oral administration, they act sequentially during gastrointestinal digestion: the fast-phase particles first contact the digestive juices, releasing a small amount of rapidly energy-providing dextrin within 5-10 minutes and stimulating the satiety center; the slow-phase gradient-degrading gel microspheres then gradually degrade, continuously releasing carbohydrates 1-3 hours after a meal; the complementary-phase particles begin to degrade 3 hours after a meal, supplementing energy supply in the late postprandial period; thus, they synergistically achieve stable blood sugar control throughout the postprandial period. This invention can match the insulin secretion window to control blood sugar, precisely delaying energy release to avoid late postprandial hypoglycemia, and achieving stable blood sugar control throughout the postprandial period.
