42.0 mm-long Al2O3 tubular ceramic substrate with 9.0 mm inner and 13.0 mm outer diameters were supplied by Jiexi Lishun Technology Co. Ltd. (Guangdong, China). The average pore size of the Al2O3 tubular substrate was 50.0 nm ± 10 nm. Ammonium molybdate tetrahydrate ((NH4)6Mo7O24·4H2O) and thiourea (CH4N2S) were purchased from Sigma Aldrich Co. (USA). In order to test the separation performance of MoS2 nanofiltration membrane, five polar solvents (methanol, ethanol, propanol, acetonitrile and acetone) and one non-polar solvent (n-hexane) were selected. Six different solvents were selected, including five polar solvents (methanol, ethanol, propanol, acetonitrile and acetone) and one non-polar solvent (n-hexane). The solute was drug small molecule acetaminophen. All solvents and solutes were purchased from Beijing Chemical Factory (Beijing, China). The purity of all the solvents were analytical pure and all chemicals were used as received without further purification.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
