  • METHOD OF INCREASING RESISTIVITY OF SILICON CARBIDE WAFER AND HIGH-FREQUENCY DEVICE AND METHOD OF MANUFACTURING THE SAME
    Publication number: 20230207386
    Abstract: A method of increasing the resistivity of a silicon carbide wafer includes providing a silicon carbide wafer with a first resistivity, and applying a microwave to treat the silicon carbide wafer. The treated silicon carbide wafer has a second resistivity. The second resistivity is higher than the first resistivity. The microwave treated silicon carbide wafer can be applied in a high-frequency device.

  • BIOMEMBRANE PHASE-CHANGE DROPLETS (PCD), DRUG CARRIER AND USE THEREOF
    Publication number: 20160317441
    Abstract: The present invention provides a biomembrane phase-change droplet (PCD), including a hydrophobic liquid core; and a phospholipid-containing biomembrane encapsulating the hydrophobic liquid core, wherein the hydrophobic liquid core is vaporized by ultrasonic irradiation. The present disclosure also provides a drug carrier, including a biomembrane phase-change droplet; and a hydrophobic drug embedded on the biomembrane of the biomembrane phase-change droplet, wherein the hydrophobic drug is presented in an amount of 1-10 wt %, based on the weight of the drug carrier. The present invention further provides the use of aforementioned biomembrane phase-change droplet (PCD) and drug carrier.
