  • Publication number: 20240066144
    Abstract: Described herein are liposome-based nanocarriers that selectively target bone marrow, minimize tumor delivery, and maintain high drug concentrations in bone marrow when compared to conventional systemic delivery. The composition of the liposome-based nanocarriers may also be tuned to selectively target lymph nodes and other reticuloendothelial system organs (e.g., spleen, e.g., livers. Also described herein are methods of imaging and mapping the bone marrow and/or other reticuloendothelial system organs using the described liposome-based nanocarriers. These methods provide high resolution non-invasive and quantitative imaging via PET, which offers advantages over conventional imaging/tracking methods. Furthermore, in certain embodiments, the liposome-based carriers are used to stabilize and deliver radioprotectant/free radical scavenger drugs to the bone marrow, thereby protecting the bone marrow from subsequent radiation exposure, thereby limiting the adverse impact of radiation exposure of the individual.

  • Patent number: 9112095
    Abstract: In some embodiments, Cu—In—Ga precursor films are deposited by co-sputtering from multiple targets. Specifically, the co-sputtering method is used to form layers that include In. The co-sputtering reduces the tendency for the In component to agglomerate and results in smoother, more uniform films. In some embodiments, the Ga concentration in one or more target(s) is between about 25 atomic % and about 66 atomic %. The deposition may be performed in a batch or in-line deposition system. If an in-line deposition system is used, the movement of the substrates through the system may be continuous or may follow a “stop and soak” method of substrate transport.

  • Patent number: 7896012
    Abstract: A shoe washing device including a motor for driving a rotor onto which the shoes are directly mounted as by aligning the soles of the shoes parallel to the axis of rotation of the rotor. The shoes are affixed onto the rotor by using a clip, strap, cage, or other attachment means. The shoes are then rotated within the wash compartment into which a wash fluid is introduced in a wash cycle and removed following a wash cycle. An integrated drying component may allow air drying of the shoes during a final spin cycle.

  • Patent number: 7718548
    Abstract: A process to form a copper-silicon-nitride layer on a copper surface on a semiconductor wafer is described. The process may include the step of exposing the wafer to a first plasma made from helium. The process may also include exposing the wafer to a second plasma made from a reducing gas, where the second plasma removes copper oxide from the copper surface, and exposing the wafer to silane, where the silane reacts with the copper surface to selectively form copper silicide. The process may further include exposing the wafer to a third plasma made from ammonia and molecular nitrogen to form the copper silicon nitride layer.

  • Patent number: 5612744
    Abstract: An image signal transmitting system uses the difference between image frames, which can transmit lots of information in a small amount of data, by transmitting the acutal moving areas which are extracted by using two change detecting masks and whose contours and textures are encoded for human visual perception. A larger amount of information is expresssed by a smaller amount of data by extracting the motion in a unit of frames, not in a unit of blocks, and expressing a converted portion by its contour and texture to facilitate the recognition of the converted portion.
