Investigation of DPPC liposomes reveals their capability to entrap Aroclor 1260, an emerging environmental pollutant

A subsequent UV-Vis analysis of HCBP by both direct and passive incorporation showed an increase in HCBP incorporation proportionate to the length of exposure time up to 24 hours and relative to the initial quantity present during the direct incorporation. Expand abstract.

Persistent Radical Pairs Between N-Substituted Naphthalimide and Carbanion Exhibit pKa-Dependent UV-vis Absorption

A new strategy is constructed for estimating and screening pKa values among different carbon acids under ambient conditions via the UV-vis absorption spectrum of persistent radical pair originating from an N-substituted naphthalimide (NNI) derivative in the presence of various carbanions in organic solutions Expand abstract.
