Seebeck effect in polypyrrole/metal junctions

open access: yes, 2009
Conducting polypyrrole films were electrochemically prepared from aqueous solution containing sodium p-toluenesulphonate as supporting electrolyte at constant current density. The films produced have electrical conductivities of about 35.8 S/cm.

Wood‐Derived 3D Conductive Cellular Bio‐C@YB2C2 Ceramics for Efficient Electromagnetic Shielding and Joule Heating

open access: yesElectron, EarlyView.
Herein, a biomimetic, anisotropic, robust wood‐derived 3D conductive Bio‐C@YB2C2 framework was synthesized by in situ boron/carbon thermal reduction reaction on the carbonized wood template. The as‐obtained Bio‐C@YB2C2 composites accurately inherit the specific microstructure of natural wood, providing pathways for terahertz wave dissipation.
