摘要： The invention relates to a carbon nanoring and a method for preparing the same. The carbon nanoring according to the present invention is composed of monolayered or multilayered coaxial carbon rings, wherein the carbon ring has a structure similar to that of a closed ring system formed by graphite sheet being rolled, and each of an axial dimension and a radial dimension of the carbon nanoring is nanoscale with the axial dimension being smaller than the radial dimension. The invention further provides a method for preparing the above carbon nanoring including calcinating in an inert atmosphere or a reducing atmosphere a layered double hydroxides obtained by intercalating a long-chain alkyl anion and a carbon source molecule, growing a carbon nanoring within a confined region between layers under the catalysis of the metal element in layers, and removing the metal and the metal oxide by dissolving in an acid to obtain the carbon nanoring. By using this method, the carbon nanoring can be effectively controlled in terms of the axial dimension, the radial dimension, and the number of layers of the carbon ring thereof. The carbon nanoring provided by the present invention has the nano-ring shaped structure and the excellent properties of carbon materials, as well as more edge carbons and dangling bonds, and thus it has broad application prospects in such field as nanodevices, energy storage and sensing.

摘要： A disk drive comprises a disk, an actuator arm and a servo controller using a position error signal to generate a controller output signal to control the actuator arm. A plant mechanically models at least a portion of the disk drive, receives a control command to which an unknown disturbance is added and generates a plant output. A disturbance observer (DOB) uses the control command and the plant output to generate a delayed and estimated version of the disturbance. The DOB comprises a Q filter having a selected center frequency. A perfect phase cancellation filter (PPCF) is configured to receive the delayed and estimated version of the disturbance, to reject selected disturbances and to align the desired attenuation frequency with the selected center frequency. The output of the PPCF is subtracted from the controller output signal to generate the control command.
