  1. Electric, elastic, and magneticproperties of Spanish Moss Lindsey Channels June 23, 2005

  2. Outline • Background on Spanish Moss • Resistance • Elasticity • Capacitance • EPR • SQUID • PPMS • Conclusions

  3. Spanish Moss

  4. Reproduction • Flower pollinates • Only grows on trees • Not parasitic • Collects water and minerals in the air

  5. Methods to Find Resistance • Gold wire and silver paste • Salt water • Graphite • Pedot

  6. Resistance with Salt Water R=0.5M =4.79m Copper  = 1.68x10-8 m Teflon  = 1016 m

  7. Resistance with Pedot R=2.7M =17.7m

  8. Resistance of Pine Needles R=35.7k =0.78m

  9. Elasticity of Spanish Moss

  10. Capacitance of Spanish Moss C = koA/d Dielectric constant = 75.5 Dielectric constant of water = 80

  11. Capacitance with Magnetic Field

  12. Electron Paramagnetic Resonance Manganese Iron III

  13. SQUID • Inconclusive • No magnetic ordering

  14. Physical Properties Measurement System • DC – measure magnetic moment = DC magnetization curve M(H) • AC – measure magnetic susceptibility. Real part is slope of M(H), imaginary is dissipation

  15. Conclusions • Durable • Insulating • Limited magnetic properties • Further research on biological properties
