| Application: | • Naphthalene was used in liquid-phase exfoliation of graphite in organic solvents for the production of graphene sheets. • It was used in preparation of carbon-coated Si70Sn30 nanoparticles. • It was used as fluorescent probe to study the aggregation behavior of sodium cholate. • It was used to investigate influence of added short chain linear and branched alcohols on the binding of 1:1 complex of naphthalene and β-cyclodextrin. |
| General description: | Heterogeneous ozonolysis of naphthalene adsorbed on XAD-4 resin has been studied using an annular denuder technique. |
