  • Process for reducing residuals content in vinyl aromatic polymers
    Patent number: 8541542
    Abstract: The present invention relates to a process for reducing residuals content in a vinyl aromatic polymer, said residuals comprising essentially unpolymerized vinyl aromatic monomer, wherein the vinyl aromatic polymer in the molten state is brought in contact with a solid in powder capable to catalyze the alkylation of said residual vinyl aromatic monomer on the vinyl aromatic polymer. Advantage of the present invention is a sharp reduction of the unpolymerized vinyl aromatic monomer in the vinyl aromatic polymer without generating a new residual and without inducing a colored vinyl aromatic polymer.

  • Magnetic transmission assembly
    Patent number: 8541922
    Abstract: A magnetic transmission assembly is adapted to integration with a motor or generator. The magnetic transmission assembly includes a rotor, a stator, and a magnetically conductive element. The rotor and the stator are sleeved coaxially and respectively have R and ST1 pole pairs. The magnetically conductive element is located between the rotor and the stator, and has permeable regions. When the magnetically conductive element is actuated, the magnetically conductive element selectively enables PN1 or PN2 permeable regions to be corresponding to the rotor and the stator. The permeable regions corresponding to the rotor and the stator interact with magnetic fields of the R and ST1 pole pairs to generate a predetermined variable-speed ratio. The magnetic transmission assembly can be integrated into the motor, so as to improve the drive power density.

  • Ion etching of growing InP nanocrystals using microwave
    Patent number: 8540892
    Abstract: High quantum yield InP nanocrystals are used in the bio-technology, bio-medical, and photovoltaic, specifically IV, III-V and III-VI nanocrystal technological applications. InP nanocrystals typically require post-generation HF treatment. Combining microwave methodologies with the presence of a fluorinated ionic liquid allows Fluorine ion etching without the hazards accompanying HF. Growing the InP nanocrystals in the presence of the ionic liquid allows in-situ etching to be achieved. The optimization of the PL QY is achieved by balancing growth and etching rates in the reaction.
