摘要:
The present invention provides a method for selectively placing carbon nanotubes on a substrate surface by using functionalized carbon nanotubes having an organic compound that is covalently bonded to such carbon nanotubes. The organic compound comprises at least two functional groups, the first of which is capable of forming covalent bonds with carbon nanotubes, and the second of which is capable of selectively bonding metal oxides. Such functionalized carbon nanotubes are contacted with a substrate surface that has at least one portion containing a metal oxide. The second functional group of the organic compound selectively bonds to the metal oxide, so as to selectively place the functionalized carbon nanotubes on the at least one portion of the substrate surface that comprises the metal oxide.

A method is provided for doping nano-components, including nanotubes, nanocrystals and nanowires, by exposing the nano-components to an organic amine-containing dopant. A method is also provided for forming a field effect transistor comprising a nano-component that has been doped using such a dopant.

In a cylinder-selective injection system for an internal combustion engine, there are cylinder-selective injection suppressions. Subsequent to the suppressions, restoring added quantities specific to an individual cylinder are generated, whose initial value is dependent upon the number of suppressed injections for the cylinder in question, and whose notching-down to zero is dependent upon the number of injections of the cylinder that have taken place after completion of the suppression.

A method for controlling a spark-ignition engine without a throttle flap is carried out with variable inlet valve opening durations. The method includes the steps of: detecting a speed signal having a value dependent upon the engine speed; detecting an accelerator pedal signal having a value dependent upon the accelerator pedal position; determining the intake valve opening durations as well as the fuel quantity in dependence upon the particular values of the engine speed signal and the accelerator pedal signal; and, determining the ignition angle in the dependence upon the particular values of the engine speed and fuel quantities. The method affords the advantage that for all driving conditions and even for sudden changes of the accelerator pedal signal, the masses of air and fuel are optimally adapted to each other in order to obtain high driving comfort without misfirings and with low toxic gas exhaust.
