Spin-Charge Separation in Polyacetylene

Effect of charge on separation of liposomes upon stagnation

Abstract Liposomes are used widely as drug delivery systems in different forms including nanosuspensions, osmotic pumps, infusion pumps and IV injections. Some of these systems (e.g. infusion or osmotic pumps) might stay stagnant for a long time during or before administration, and therefore, might face phase separation. In spite of these, there is no data available about the behavior of lipos...

Photoinduced charge separation in platinum acetylide oligomers.

The series of three donor-spacer-acceptor complexes, DPAF-Ptn-NDI, has been synthesized and characterized using time-resolved absorption spectroscopy. In these complexes, the donor is a (diphenylamino)-2,7-fluorenylene (DPAF) unit, the acceptor is a naphthalene diimide (NDI), and the spacers are a series of platinum acetylides of varying lengths, [-Pt(PBu(3))(2)-C≡C-Ph-C≡C-](n) (where Bu = n-bu...

Charge separation via strain in silicon nanowires.

Axial charge separation in small diameter, partially strained silicon nanowires is predicted from ab initio calculations with electrons and holes located in different ends of the wires. We show that this effect can be understood from the topologies of near-gap wave functions, and that it is enhanced by quantum confinement. The possibility of utilizing partial strain for charge separation at the...
