Poly(aniline‐co‐o‐anisidine) (P(An‐co‐o‐As))/sulfonated multiwalled carbon nanotubes (s‐MWNTs) composites were prepared by adsorption of P(An‐co‐o‐As) on MWNTs surface in a N,N‐dimethyl acetamide (DMAc) solution. This research demonstrated that it was possible to sulfonate MWNTs and use a copolymer as a substitute for…

Ten steroidal saponins have been isolated form the seeds of Hyoscyamus niger L. for the first time and their structures have been elucidated. Seven saponins belong to spirostane series, two are furostane-type and one is pregnane glycoside. Hyoscyamosides B, C and C2 are new steroidal saponins, which have never been re…

Polymer brushes are assemblies of macromolecules that are tethered by one end to a surface or interface. The advantage of polymer brushes over other surface modification methods (e.g. selfassembled monolayers) is their mechanical and chemical robustness, coupled with a high degree of synthetic flexibility towards the…

We present the design of a directional dual band six-cell distributed power amplifier (DPA) that can direct the amplified power to the output ports depending on the input RF frequency. Different from conventional DPA, the dual band DPA implements the composite right/left-handed (CRLH) transmission line (TL) structure…

In the late 1980s and again in the past few years, some turbine generator stator windings have apparently failed due to a mechanism variously referred to as spark erosion or vibration sparking. The mechanism can produce relatively intense sparking between the surface of the stator bar and the core. The intensity of th…

We report a successful implementation of epitaxially grown Phosphorus-doped (P-doped) embedded SiC stressors into SOI nMOSFETs. We identify a process integration scheme that best preserves the SiC strain and minimizes parasitic resistance. At a substitutional C concentration (Csub) of ∼1.0%, high performance nFETs wit…
