Abstract

Foam separation for simultaneous removal of rhodamine B (RhB) and cetyl trimethyl ammonium bromide (CTAB)/sodium dodecyl benzene sulfonate (SDBS) from model wastewater was studied. The effect of the surfactant type, aeration rate, temperature, and initial pH on the removal efficiency and enrichment ratio of dye/surfactant were investigated. The results indicated that electrostatic attraction between the dye and surfactant have a great effect on the recovery of the dye and surfactant. The aeration rate has significant influence on the CTAB and RhB removal and enrichment, while the initial pH has a great effect on the RhB removal, but little effect on CTAB removal. Moreover, dissipative particle dynamics (DPD) was employed to simulate the interaction between the surfactant and the dye. [ABSTRACT FROM AUTHOR]

31. Polymer-Assisted Polymorph Transition in Melt-Processed Molecular Semiconductor Crystals.

Author

Abstract

A previously unreported polymorph of 5,11-bis(triisopropylsilylethynyl)anthradithiophene (TIPS ADT), Form II, crystallizes from melt-processed TIPS ADT films blended with 16 ± 1 wt % medium density polyethylene (PE). TIPS ADT/PE blends that initially are crystallized from the melt produce twisted TIPS ADT crystals of a metastable polymorph (Form IV, space group P 1̅) with a brickwork packing motif distinct from the slipstack packing by solution-processed TIPS ADT crystals (Form I, space group P 2 1 / c ) at room temperature. When these films were cooled to room temperature and subsequently annealed at 100 °C, near a PE melting temperature of 110 °C, Form II crystals nucleated and grew while consuming Form IV. The growth rate and orientations of Form II crystals were predetermined by the twisting pitch and growth direction of the original banded spherulites in the melt-processed films of the blends. Notably, the Form IV → II transition was not observed during thermal annealing of neat TIPS ADT films without PE. The presence of the mobile PE phase during thermal annealing of TIPS ADT/PE blend films increases the diffusion rate of TIPS ADT molecules, and the rate of nucleation of Form II. Form IV crystals are more conductive but less emissive compared to Form II crystals., Competing Interests: The authors declare no competing financial interest., (© 2024 The Authors.
