20090179171 | CONTROL OF MATERIALS AND POROUS MAGNETIC PARTICLES - The present invention uses externally applied electromagnetic stimulus to control and heat porous magnetic particles and material associated with the particles. The particles contain magnetic material, such as superparamagnetic iron oxide and are associated with a material. Application of a DC magnetic field allows them to be moved with their associated material, and application of an AC RF electromagnetic field allows them to be heated with their associated material. The material can be associated with the particles by being contained in the pores of the particles, or in other cases the particles can adhere to the associated material, which can be an aqueous droplet. The present invention also provides a multi-layer porous magnetic particle. The particle includes a host layer having pores sized to accept magnetic nanoparticles. Magnetic nanoparticles are infused within pores of the host layer An encoding layer includes pores that define a spectral code. The pores in the encoding layer are sized to substantially exclude the magnetic nanoparticles. The encoding layer can also be a multi-layer, exhibiting, for example, a complex spectral code. | 07-16-2009 |

20110048587 | Amorphous Alloy Materials - Design and fabrication processes and compositions for bulk metallic glass materials. Examples of bulk metallic glasses based on the described compositions may contain a high atomic percent of titanium or iron, which is alloyed with metalloid elements and refractory metals. The compositions can be designed using theoretical calculations of the liquidus temperature to have substantial amounts of refractory metals, while still maintaining a depressed liquidus temperature. The alloying elements are molybdenum, tungsten, chromium, boron, and carbon may be used. Some of the resulting alloys are ferromagnetic at room temperature, while others are non-ferromagnetic. These amorphous alloys have increased specific strengths and corrosion resistance compared to conventional high strength steels. | 03-03-2011 |
