  • Publication number: 20170069412
    Abstract: A one-pot microwave synthesis of Fe0.65Pt0.35@Co allows systematic growth of the soft-magnet Co shell (0.6 nm to 2.7 nm thick) around the hard-magnet Fe0.65Pt0.35 core (5 nm in diameter). Controlled growth leads to a four-fold enhancement in energy product of the core-shell assembly as compared to the energy product of bare Fe0.65Pt0.35 cores. The simultaneous enhancement of coercivity and saturation moment reflects the onset of theoretically predicted exchange spring behavior. The demonstration of nanoscale exchange-spring magnets will result in improved high-performance magnet design for energy applications.

  • Patent number: 8663491
    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.

  • Patent number: 8414746
    Abstract: A method is provided for producing crystalline nanoparticle semiconductor material. The method includes the steps of mixing a precursor in a solvent to form a reaction mixture and subjecting the reaction mixture to microwave dielectric heating at sufficient power to achieve a superheating temperature of the reaction mixture. A growth-phase reaction is permitted to proceed, wherein nanoparticles are formed in the heated reaction mixture. The reaction is then quenched to substantially terminate nanoparticle formation.

  • Patent number: 7927516
    Abstract: A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.
