  • Publication number: 20240136531
    Abstract: A conductive composite material, a method of preparing the same, and a secondary battery including the same. The conductive composite material may increase the proportion of an active material when forming an electrode by chemically bonding a conductive material and a binder to each other. A method of preparing the conductive composite material comprises ionizing carbon-based particles in a predetermined polarity, ionizing PTFE particles in a polarity different from that of the carbon-based particles, and chemically bonding the ionized carbon-based particles and the ionized PTFE particles, which are ionized in different polarities, to each other.

  • Patent number: 6895107
    Abstract: A fully-automated method for segmentation of white matter, gray matter, and cerebral spinal fluid (CSF) and for calculating their respective volumes is disclosed. The technique preferably uses a T2-weighted scan and a proton-density scan. The T2-weighted scans are used to highlight those portion of the brain corresponding to CSF. Thereafter, the proton density images are separated in CSF-containing and CSF-free portions, in accordance with the T2-weighted images. The CSF-free portion is then segmented into white matter and gray matter portions. The CSF-containing portion is further segmented into pure CSF-regions, and regions containing a mixture of gray and white matter and CSF. After CSF is segmented from this mixture, the white and gray matter and again segmented, and the respective volumes of white matter, gray matter, and CSF are calculated.
