  4. Reinforced composites Colloids - FuWeresearch Metal matrix composites

  5. Reinforced composites Colloids - FuWeresearch Ceramic matrix composites

  6. Electronic bridge Single tube Semiconductor-enriched SWNTs are usable in thin-film FETs (TFT) High switching ratios can be achieved (app. 103) and high drive currents (>1 mA) They deliver strong photocurrents They are both photoluminescent and electroluminescent. These high performance semiconducting SWNT FETs also have demonstrated operating frequencies up to 80 GHz (109 operations per second).

  7. CNT Yarns Yarn

  8. Artificial muscles Yarn Aerogel-like material 1.5 mg/cm3 Operates in a wide temperature range (80-1900 K) Air density: 1.225 mg/cm3 Mars temp. range: 130 to 300 K Mercury temp. range : 100 to 700 K Moon temp. range : 40 to 400 K
