  • Publication number: 20240145561
    Abstract: A semiconductor may include an active region, an epitaxial source/drain formed in and extending above the active region, and a first dielectric layer formed over a portion of the active region. The semiconductor may include a first metal gate and a second metal gate formed in the first dielectric layer, a second dielectric layer formed over the first dielectric layer and the second metal gate, and a titanium layer, without an intervening fluorine residual layer, formed on the metal gate and the epitaxial source/drain. The semiconductor may include a first metal layer formed on top of the titanium on the first metal gate, a second metal layer formed on top of the titanium layer on the epitaxial source/drain, and a third dielectric layer formed on the second dielectric layer. The semiconductor may include first and second vias formed in the third dielectric layer.

  • Patent number: 11964881
    Abstract: A method for making iridium oxide nanoparticles includes dissolving an iridium salt to obtain a salt-containing solution, mixing a complexing agent with the salt-containing solution to obtain a blend solution, and adding an oxidating agent to the blend solution to obtain a product mixture. A molar ratio of a complexing compound of the complexing agent to the iridium salt is controlled in a predetermined range so as to permit the product mixture to include iridium oxide nanoparticles.

  • Publication number: 20240107414
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for switching a secondary cell to a primary cell. A user equipment (UE) monitors a first radio condition of the UE for beams of a primary cell and a second radio condition for beams of one or more secondary cells configured for the UE in carrier aggregation. The UE transmits a request to configure a candidate beam of at least one candidate secondary cell as a new primary cell in response to the first radio condition not satisfying a first threshold and the second radio condition for the at least one candidate secondary cell satisfying a second threshold. A base station determines to reconfigure at least one secondary cell as the new primary cell. The base station and the UE perform a handover of the UE to the new primary cell.

  • Publication number: 20200337835
    Abstract: A medical implant has a center axis and includes first and second flexible waved strands disposed around the center axis. The second flexible waved strand is in spatial communication with the first flexible waved strand to form a plurality of first unit shapes and a plurality of second unit shapes. Therein, the first unit shapes and the second unit shapes are staggered around the center axis. The first unit shapes are coupled to the second unit shapes to cause the first and second flexible waved strands to move substantially along the center axis. The first and second flexible waved strands together define a self-anchoring configuration in a radial direction perpendicular to the center axis so that a ratio of a von Mises stress to an axial displacement of the medical implant during an implant compression of the medical implant is greater than 0.1 and less than 30.

  • Publication number: 20140314867
    Abstract: A vitamin K2 microsphere. The microsphere includes a poly(lactide-co-glycolide) acid (PLGA) particle, in which the Mw of PLGA is between 1000 and 300000, and the molar ratio between the lactide repeat units and the glycolide repeate unit is 1-9:9-1; and one or more vitamin K2 molecules are embedded in the PLGA particle, wherein the vitamin K2 is present in an amount of 0.005-75 wt %, based on the weight of the microsphere. Also disclosed are a method of preparing the vitamin K2 microsphere, a method of treating osteoporosis using this microsphere, and a pharmaceutical composition containing the microsphere.
