Electrosynthesis of polyacrylic/polypyrrole composites: Formation of polypyrrole wires [PDF]

open access: yesSynthetic Metals, 1999
Abstract A new preparation method is reported for the synthesis of conducting polypyrrole nanowires. This two-step all-electrochemical method consists in the cathodic grafting of a thin polyacrylate film on a carbon electrode, which is then used as an anode for the electropolymerization of pyrrole.

Drug‐Free Thrombolysis Mediated by Physically Activated Micro/Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Overview of particle‐mediated thrombolytic effects (thermal, mechanical, and chemical) and their activating physical stimuli (light, ultrasound, and magnetic field) in drug‐free thrombolysis. ABSTRACT Thrombus‐associated disorders rank among the world's leading causes of death, with ischemic heart disease and stroke as the main contributors.
