The in vitro antioxidant assay showed that the four sea buckthorn polysaccharides (SP, SPA, SPB, and SPC) were good at getting rid of superoxide anion and DPPH radicals, especially ABTS radicals. They were also better at getting rid of free radicals than VC at low concentrations, and they were also good at reducing other molecules. Therefore, sea buckthorn polysaccharide can be used as a natural antioxidant with great potential as a functional cosmetic ingredient.

A research team from Zhejiang University has developed a strong and tough CoNiCr alloy by overcoming intermediate temperature brittleness (ITB). By using the strategy of grain boundary engineering (GBE), the strength and ductility of the alloy are simultaneously improved at elevated temperature. The solution here might provide a pathway to overcome the GB brittleness, which currently restricts practical application of many metallic alloys.
