An electrophotographic toner comprising a resin and a colorant, wherein: a toner particle comprises a domain in the toner particle, the domain comprising a polar wax having a first polar group and a non-polar wax; and the resin contains a second polar group. The invention further relates to compositions prepared from such modified alkyd compositions. The doped semiconductor region includes a surface portion at a surface of the active region, and a sidewall portion lower than a bottom surface of the surface portion. The silicon carbide layer is compatible with integrated circuit fabrication processes. In terms of the aggregate throughput, the interference estimation method can provide a significant gain.
