Abstract: A method and system is disclosed to detect and analyze an electric signal based on movement between an element and a counter electrode influenced by a nonlinear electric field produced by an electrical signal impressed between the element and counter electrode. Through detection of changes in the distance between the element and the counter electrode characteristics of the element and/or the environment of the element may be ascertained. Changes in the distance between the element and the counter electrode may be monitored based on changes in the value of capacitance between the element and counter electrode. The disclosed devices and methods may be employed to detect, for instance, presence of chemical/biological species in a sample or measure physical parameters of a sample such as pressure/acceleration, density, viscosity, magnetic force, temperature, and/or extremely small masses.

Abstract: The present invention discloses a relatively simple CVD method for forming specifically tailored carbon-based nanostructures. In general, the method is a chemical vapor deposition method in which at least a portion of the precursor materials are provided as a liquid at atmospheric conditions. The precursor materials include at least one carbon source and at least one catalyst source. Optionally, the precursor materials can also include one or more dopant sources. The carbon source and the optional dopant source can be injected as liquids into the system, and the liquid catalyst source can be either injected into the system or located on a substrate in the reactor prior to the process. Very high yield of nanostructures exhibiting particular characteristics can be attained by the process.
