Charge transport and structure in semimetallic polymers [PDF]
Journal of Polymer Science Part B: Polymer Physics, 2017 ABSTRACTOwing to changes in their chemistry and structure, polymers can be fabricated to demonstrate vastly different electrical conductivities over many orders of magnitude. At the high end of conductivity is the class of conducting polymers, which are ideal candidates for many applications in low‐cost electronics. Here, we report the influence of the

On a mass-charge structure of gauge invariance [PDF]
Physics Essays, 2016 The mathematical logic of a true nature of mirror symmetry expresses, in the case of the Dirac Lagrangian, the ideas of the left- and right-handed photons referring to long- and short-lived particles, respectively. Such a difference in lifetimes says about the photons of the different components having the unidentical masses, energies, and momenta ...

Structure of Strongly Charged Polyelectrolyte Solutions
Macromolecules, 2006 Molecular dynamics simulation and recent theory are used to examine density correlations in semidilute solutions of highly charged, intrinsically flexible and hydrophilic polyelectrolytes in low salt. Quantitative comparison with no adjustable parameters is made with recent scattering and osmometry experiments.
