Evidence for Morphology Control by Polyelectrolyte Templating in PEDT:PSSH

Advanced Functional Materials, Volume 34, Issue 45, November 5, 2024.
Using sulfonated polystyrenes—PS‐co‐SSH and PS‐co‐SSNa—as substrate polyelectrolytes for the polymerization of PEDT, the authors discover the effect of Polyelectrolyte Templating, where the morphology of the substrate polyelectrolyte determines that of the growing PEDT chain—whether extended, coiled or collapsed, and hence the electrical, electronic ...

Symmetry, winding number and topological charge of vortex solitons in discrete-symmetry media

, 2008
We determine the functional behavior near the discrete rotational symmetry axis of discrete vortices of the nonlinear Schr\"odinger equation. We show that these solutions present a central phase singularity whose charge is restricted by symmetry ...

Twisted superfluids in moving frame

, 2020
{Helical waveguide filled by superfluid is shown to transform the linear displacements of reference frame $\vec V$ into rotations of atomic ensemble and vise versa rotations of reference frame $\vec \Omega_{\oplus}$ are the cause of linear displacements ...

Dark matter production from cosmic necklaces

, 2006
Cosmic strings have gained a great interest, since they are formed in a large class of brane inflationary models. The most interesting story is that cosmic strings in brane models are distinguished in future cosmological observations.

Effect of tabs on the evolution of an axisymmetric jet [PDF]

The effect of vortex generators, in the form of small tabs at the nozzle exit, on the evolution of an axisymmetric jet was investigated experimentally over a jet Mach number range of 0.34 to 1.81.

The Consequences of the modulation instabilities [PDF]

, 2018
There are various cases of the development of the modulation instability of intense periodic structures in wave and non-wave media (see, for example [1]). The peculiarity of the modulation instability is the appearance of the perturbation spectrum, which
