With special confined water pools, reverse micelles (RMs) have shown potential for a wide range of applications. However, the inherent water-insolubility of RMs hinders their further application prospects, especially for applications related to biology. We recently reported the first successful transfer of RMs from organic media to an aqueous phase without changing the smart water pools by the ...

A series of sulfonic acid polymers were shown to be potent and selective inhibitors of respiratory syncytial virus (RSV) and influenza A virus. The compounds inhibit the replication of RSV and influenza A virus in HeLa and MDCK cells, at concentrations of 0.16 and 4.0 micrograms/ml, respectively, and are nontoxic to growing cells at concentrations of > 100 micrograms/ml. The mode of antiviral a...

The cascade reaction sequence is a fascinating subject in catalysis. A rationally designed cascade reaction sequence can simplify the synthetic route, reduce the amount of waste and lower the operation cost. The key for a successful cascade reaction sequence is the multifunctional catalyst. With a suitable multifunctional catalyst, multiple synthesis steps can proceed in one pot with high yield...

a simple and rapid spectrophotometric method for the determination of nitrite in water and soil preparation samples has been developed. determination of nitrite is based on diazotization of p-nitro aniline with nitrite and subsequent coupling with 4-amino-3-hydroxynaphthalene-1-sulfonic acid in hydrochloric acid. the factors affecting the reaction i.e. concentration of p-nitro aniline, concentr...

Biodiesel was prepared from Citrullus colocynthis oil (CCO) via a two-step process. The first esterification step was explored in two ionic liquids (ILs) with 1,3-disulfonic acid imidazolium hydrogen sulfate (DSIMHSO4) and 3-methyl-1-sulfonic acid imidazolium hydrogen sulfate (MSIMHSO4). Both ILs appeared to be good candidates to replace hazardous acidic catalyst due to their exceptional proper...
