Chemical doping of individual semiconducting carbon-nanotube ropes [PDF]
We report the effects of potassium doping on the conductance of individual semiconducting single-walled carbon nanotube ropes. We are able to control the level of doping by reversibly intercalating and de-intercalating potassium. Potassium doping changes

Release Pattern of Nitrogen and Potassium from Controlled Release Fertilizer (CRF) in the Soil
Nitrogen (N) and potassium (K) are macronutrients that plants need for better growth and yield. However, they are readily lost from the soil through volatilization, denitrification, and leaching, aside from being absorbed by plant roots.
