Cavities formed by proteins have been utilized as the reaction chamber for the fabrication of a range of inorganic nanoparticles, providing control of the size of particles by limiting growth and preventing agglomeration. In crystal form, proteins construct molecular arrays that can provide regularly arranged sites for nanoparticles. Here we report the(More)
A new analytical device model applicable to deep sub-micron MOSFETs is proposed. The new pseudo two-dimensional model includes velocity overshoot effect by the use of the extended drift-diffusion (EDD) model. Calculated current voltage characterisitcs agree well with the reported device characteristics of deep sub-micron MOSFETs. The model is found to be(More)
A novel composite consisting of hydroxyapatite (HAp) microparticles covalently coupled onto a silicone sheet was developed. Initially, an acrylic acid (AAc) -grafted silicone sheet with a 16.7 microg/cm(2) surface graft density was prepared by corona-discharge treatment. The surface of sintered, spherical, carbonated HAp particles with an average diameter(More)
