摘要:
Disclosed is a method for fabrication of porous carbon fibers. More particularly, the method for fabrication of porous carbon fibers comprises the steps of: processing starch to prepare a gelled starch solution; adding organic acid to the gelled starch solution to prepare a starch solution; dissolving carbon nanotubes in a solvent and adding fiber formable polymer thereto to prepare a carbon nanotube/fiber formable polymer solution; mixing the starch solution with the carbon nanotube/fiber formable polymer solution obtained from the above steps, in order to prepare a carbon nanotube/starch/fiber formable polymer solution; electro-spinning or wet-state spinning the prepared carbon nanotube/starch/fiber formable polymer solution to produce starch composite fibers; oxidation heating the starch composite fibers, then, executing carbonization and vacuum heat treatment of the heated fibers, so as to fabricate the porous carbon fibers. The fabricated porous carbon fiber has high specific surface area and high capacitance, thereby being favorably applicable in manufacturing electrodes for a super capacitor, fuel cell, etc.

The invention relates to methods for fabricating ceramic nanocomposite powders, comprising a ceramic matrix and carbon nanotubes homogeneously dispersed in the ceramic matrix. The ceramic nanocomposite powders of the invention can prevent property deterioration due to agglomeration of carbon nanotubes.
摘要:
A biomedical device for comprehensive and a data-driven patient monitoring is disclosed. The biomedical device includes a receiver to receive sensor data associated with physiological signals and perform feature computations on the sensor data. A control system is included to classify the sensor data using the feature computations to generate medically-relevant decisions and identify relevant data instances, and to automatically select a set of relevant data instances. A base station or programming interface can provide a patient-generic seed model to the biomedical device. The patient-specific seed model is usable by the control system to automatically select a coarse set of relevant data instances that are transmitted to the base station, which in turn analyzes the coarse set of relevant data instances to generate a patient-specific model. The biomedical device receives the patient-specific model, which is usable by the control system to automatically select a refined set of relevant data instances.
