  • Publication number: 20210020904
    Abstract: The disclosure relates to a carbon-based electrode material that has been graphitized to hold ions in the electrode of a battery and more particularly include carbide or carbide and nitride surfaces that protect the graphite core. The preferred batteries include metal ion such as lithium ion batteries where the carbon-based electrode is the anode although the carbon-based electrode may also serve in dual ion batteries where both electrodes may comprise the graphitized carbon-based electrodes. The electrodes are more amorphous than conventional graphite electrodes and include a carbide or nitride containing surface treatment.

  • Publication number: 20200238018
    Abstract: A digital syringe is used with conventional polymer disposable syringe construction to be practical in the medical environment. Errors associated with the larger volumes of the syringes (which exacerbate minor errors in plunger position) and the flexibility and dimensional variations of the polymer plungers are accommodated by direct measurement of the syringe plunger position rather than indirect measurement of motor position and inference of syringe plunger position. This direct measurement eliminates mechanical tolerances (“stack up”) in the motor, gear train, and lead screw on plunger movement, an effect exacerbated by flexibility of the plunger and changes in syringe resistance and medicament viscosity, for example, with different medicaments or when the syringe is refrigerated. The digital syringe may be combined with the motor unit to provide additional versatility.

  • Publication number: 20200172402
    Abstract: Carbon particles are coated with a water-soluble carbon residue material by oxidizing the carbon residue in water and forming a solid coating on the particles. The coated particles may be heated to graphite forming temperatures to prepare the coated particles for use an anode powder for a battery.

  • Publication number: 20190161688
    Abstract: The invention relates to removing contaminants from hydrocarbon oil or carbon precursor oil using solid sorbents that are comprised primarily of carbon and preferably of coke particles. The coke particles have an affinity for contaminants in hydrocarbon oil and carbon precursor oil and are sized to be filtered from the liquid fuel without plugging. As the contaminants agglomerate onto the solid sorbent, the resulting particles form a filter cake on conventional filter materials in such a way as to allow the hydrocarbon oil or carbon precursor oil to pass on through without significant pressure drop or delay.

  • Patent number: 10303004
    Abstract: The present disclosure relates to the field of quantum dot display technology and discloses a method for manufacturing a quantum dot display device. The method comprises: providing an array substrate and a counter substrate opposite to each other; printing an alignment solution containing a quantum dot material onto a side of the array substrate facing the counter substrate; removing a solvent in the alignment solution printed onto the side of the array substrate facing the counter substrate; heating the array substrate after removal of the solvent; and providing a backlight source at a side of the array substrate facing away from the counter substrate. The present disclosure further relates to a corresponding quantum dot display device. With such a manufacturing method, the display quality of the resulting quantum dot display device is greatly improved, and the associated manufacturing cost and process difficulty are reduced.

  • Patent number: 10059888
    Abstract: The invention relates to removing contaminants from oil using solid sorbents that are comprised primarily of carbon and preferably of coke particles. The coke particles have an affinity for contaminants in oil and are sized to be filtered from oil without plugging. Most contaminants have such a small size that they tend to plug up filters. As the contaminants agglomerate onto the solid sorbent, the resulting particles form a filter cake on conventional filter materials in such a way as to allow the oil to pass on through without significant pressure drop or delay.
