  • Publication number: 20250092572
    Abstract: The present disclosure provides a method for preparing a gallium nitride (GaN) single-crystal substrate with an edge metal mask technology. The method includes: preparing a metal mask ring on a composite epitaxial substrate, epitaxially growing a GaN single-crystal sacrificial layer in a confined manner, performing separation with interlayer decoupling of single-crystal graphene through an in-situ temperature gradient method to obtain a self-supporting GaN single-crystal sacrificial layer, epitaxially growing a GaN single-crystal thick film in a diameter expanded manner, and performing chemico-mechanical trimming on the GaN single-crystal thick film to obtain a stress-free self-supporting GaN single-crystal substrate. The metal mask ring is compatible with the GaN single-crystal preparation process (hydride vapor phase epitaxy (HVPE)), and efficiently catalyzes decomposition reaction of the nitrogen source.

  • Patent number: 8323655
    Abstract: Multiple myeloma (MM) is a clonal B cell malignancy and remains essentially incurable by conventional anti-tumor therapy. Patients with MM have a median survival of only three years. MM is characterized by proliferation and accumulation of mature plasma cells in the bone marrow (BM) leading to bone destruction, BM failure, anemia, and reduced immune function. The identification of MHC Class I, HLA-A2, associated peptides presented on multiple myeloma cells is an important step in developing immunotherapies for MM. Presented here are methods for creating activated T lymphocytes that are cytotoxic to both peptide loaded T2 target cells and multiple myeloma cell lines.
