Briefly, 4×10 4 cells/mL of CaCo-2 and L-929 were seeded into a 96-well plate and incubated at 37 °C with 5% CO 2 atmosphere for 24 h. Cells were treated with 100 μL of varying concentrations of SISE AgNPs (26.875–0.209 μg/mL) and incubated for 24 h.


Liquid sodium metal is used in certain nuclear reactor designs as a cooling fluid, because it is very effective at transferring large amounts of heat from one place to another. Personally I'd rather have something a bit less violently explosive as the cooling fluid in my nuclear reactor, but so far as I know there haven't been any major ...


I assume your idea is to add sodium chloride to water and use that as an antifreeze because the freezing temperature of the solution is lower than that of pure water. One big problem in automotive cooling systems is caking up of deposits inside the radiator and other piping. You may live in an area where teakettles and water heaters cake up ...

sodium ions may enhance CE in h-WO 3 and m-WO 2.72 by directing cation insertion into optically active hexagonal tunnel sites. Herein, we demonstrate that nanostructured m-WO 2.72 exhibits high CE upon charging with a sodium-based electrolyte. Sodium ions can selectively insert into optically active hexagonal tunnel sites, leading to improved CE
