  • Patent number: 10475550
    Abstract: The present invention relates to a conductive two-dimensional polyaniline (PANT) nanosheets template. The method comprises polymerizing aniline on an ice surface. The PANI nanosheets show distinctly high current flows of 5.5 mA at 1 V and a high electrical conductivity of 35 S/cm, which mark a significant improvement over previous values on other PANIs reported over the past decades. These improved electrical properties of the PANI nanosheets are attributed to the long-range ordered edge-on ?-stacking of the quinoid ring, ascribed to the ice surface-assisted vertical growth of PANI. The PANI nanosheet can be easily transferred onto various types of substrates via float-off from the ice surfaces. In addition, PANI can be patterned into any shape using predetermined masks, and this is expected to facilitate the eventual convenient and inexpensive application of conducting polymers in versatile electronic device forms.

The cell compartments includes an anode compartment having an anode in a side, and a cathode compartment having a cathode on another side separated by an ion exchange membrane. The anode is a glassy carbon modified with a multi-walled carbon nanotube/tin oxide nanocomposite configured to attach a biocatalyst, immersed in a solution. The cathode is a platinum electrode immersed in another solution. The anode and cathode are electrically connected to one another via a resistance to generate electricity. The large specific surface area and biocompatibility of the multi-walled carbon nanotube/tin oxide nanocomposite anode in the microbial fuel cell increases the bacterial biofilm formation and charge transfer efficiency.

  • Patent number: 10390468
    Abstract: The present disclosure describes aspects of a wireless power-transmission shield for a wireless charger. The wireless charger includes a wireless power transmitter configured to generate an alternating magnetic field at a charging frequency. As a result of the alternating magnetic field, a spurious electromagnetic field is further generated at a spurious frequency different than the charging frequency. The wireless charger includes a shield having an associated conductivity or an associated impedance. The shield is configured to be substantially transparent to the alternating magnetic field based on the charging frequency and the associated conductivity of the shield or the associated impedance of the shield. The shield is further configured to be lossy to the spurious electromagnetic field based on the spurious frequency and the associated conductivity of the shield or the associated impedance of the shield.

  • Patent number: 10385189
    Abstract: The present invention provides a graphene composite powder form material that is suitable for industrialized application. The graphene composite powder form material is composited by graphene materials and a high-molecular compound. The high-molecular compound is uniformly coated on surfaces of the graphene material. Any adjacent graphene materials are separated by the high-molecular compound. An apparent density of the graphene composite powder form material is larger than or equal to 0.02 g/cm3. Under an external pressure, the graphene materials in the graphene composite powder form material do not re-stack, and can be easily restored to original form, which benefit the storage and transportation. Besides, the graphene composite powder form material has a good compatibility in other material systems, which greatly broadens the application fields in the downstream products and successfully solves the problem in industrial application.
