The effect of time‐varying electric fields on the stresses in model and commercial electrorheological (ER) fluids in steady shear were surveyed. The dependence of the time‐averaged shear stress with the frequency of an applied alternating (ac) sq

On introduit un parametre d'ordre anneau torsionnel; on trouve deux defauts de type soliton de ce parametre d'ordre. Ces solitons sont anticipes pour presenter une relation spin-charge conventionnelle au contraire des solitons en liaisons alternative

It is demonstrated that emeraldine base polymer films can be processed to form strong oriented materials by maintaining the polymer under stress while the temperature is raised toward the glass transition temperature. After the orientation process, t

Absorption and photoinduced absorption spectroscopies are reported for pernigraniline base (PNB). Direct absorption of PNB shows the band gap energy at 2.3 eV and π − π ∗ transition energies at 3.8 and 4.3 eV. The photoinduced absorption (PA) s

Photoinduced absorption spectroscopy has been used to study a variety of forms of polyaniline. Experiments on emeraldine base and leucoemeraldine base have led to a picture of the photoproduction and decay of massive, long-lived defect states that ca
