Solid-state batteries based on a metallic Li anode and nonflammable solid electrolytes (SEs) are anticipated to achieve high energy and power densities with absolute safety. In particular, cubic garnet-type Nb-doped LiLaZrO (Nb-LLZO) SEs possess superior ionic conductivity, are feasible to prepare under ambient conditions, have strong thermal stability, and are of low cost. However, the interfacial compatibility with Li metal and Li dendrite hazards still hinder the applications of Nb-LLZO.

is commonly used as a traditional Chinese medicine for the treatment of liver diseases due to its hepatoprotection and anti-inflammation, but the absorption properties of its main bioactive ingredients remain unclear. Our previous studies verified that the flavonoid -glycosides, including vicenin-2 (1: ), isoschaftoside (2: ), and schaftoside (3: ), were the major active components in for hepatic protection against nonalcoholic fatty liver disease, hepatitis, and hepatic fibrosis. This study investigated the bioaccessibility and transport mechanisms of total flavonoid -glycoside, as well as vicenin-2 (1: ), isoschaftoside (2: ), and schaftoside (3: ), in by simulated digestion and use of the Caco-2 cell model.

Lipid deposition induced various diseases including nonalcoholic fatty liver and hyperlipemia. The excessive accumulation of triglyceride (TG) and the deposition of fat were the two most critical causes. Here, we developed FeO@OA@Poloxamer nanoparticles (NPs) with amphiphilic structures, which exhibited an excellent role in eliminating excess TG.

subsp (Hance) Verdc. (Leguminosae) is a well-known edible plant usually added to soups and beverages. In this study, vicenin-2 (1: ), isoschaftoside (2: ), schaftoside (3: ), and their enrichment fraction, total flavonoid -glycosides, derived from the extracts of , were firstly found to prevent nonalcoholic fatty liver disease both and .

Foveated imaging systems have the ability to capture local high-resolution or high-magnification images with wide field of view (FOV); thus, they have great potential for applications in the field of monitoring and remote sensing of unmanned aerial vehicles. Hence, foveated optical systems are in strong demand. However, the existing foveated imaging systems either are equipped with expensive modulators or require fixing the local high resolution imaging field, which is not suitable for mass production or object tracking in industrial applications.
