The paper demonstrates the feasibility of the gel-clot method for the analysis of bacterial endotoxins in water extracts of ultrapure paraffin oil which is a water insoluble oily medical device. Because ultrapure paraffin oil is water insoluble oily liquid, the ultrapure paraffin oil (10 mL) was shaken with 10 mL water for 15 minutes at 2000 rpm, the endotoxin present was extracted to the aqueo...

The phase change material is a hot research topic in solar thermal storage systems. However, the conductivity of pure materials usually low, which hinders its application facilities. In this study, copper foam used to increase characteristics paraffin. Simulations are conducted compare melting paraffin and paraffin/copper composite material. A visualized experimental device was designed built, ...
