Band offset determination of p-NiO/n-TiO₂ heterojunctions for applications in high-performance UV photodetectors

Nickel oxide (NiO)-decorated titanium dioxide (TiO₂) heterojunction photodetectors were prepared by two-step anodization. Surface scattering of NiO particles was successfully controlled by varying second-step ano...

CD138-negative clonogenic cells are plasma cells but not B cells in some multiple myeloma patients

Clonogenic multiple myeloma (MM) cells reportedly lacked expression of plasma cell marker CD138. It was also shown that CD19⁺ clonotypic B cells can serve as MM progenitor cells in some patients. However, it is u...
