摘要： A method of degrading a dye in an aqueous solution including contacting nanoparticles with the dye in the aqueous solution and irradiating the aqueous solution. The nanoparticles have a formula of Zn1-2xCexYbxO, x=0.01-0.1, and where at least 90 wt. % of the dye is degraded during the irradiating of the aqueous solution.

摘要： A method of producing polycrystalline Y3Ba5Cu8Oy (Y-358) whereby powders of yttrium (III) oxide, a barium (II) salt, and copper (II) oxide are pelletized, calcined at 850 to 950° C. for 8 to 16 hours, ball milled under controlled conditions, pelletized again and sintered in an oxygen atmosphere at 900 to 1000° C. for up to 72 hours. The polycrystalline Y3Ba5Cu8Oy thus produced is in the form of elongated crystals having an average length of 2 to 10 μm and an average width of 1 to 2 μm, and embedded with spherical nanoparticles of yttrium deficient Y3Ba5Cu8Oy having an average diameter of 5 to 20 nm. The spherical nanoparticles are present as agglomerates having flower-like morphology with an average particles size of 30 to 60 nm. The ball milled polycrystalline Y3Ba5Cu8Oy prepared under controlled conditions shows significant enhancement of superconducting and flux pinning properties.

摘要： A magnetoelectric multiferroic nanocomposite. The nanocomposite comprises a ferroelectric perovskite oxide and a rare-earth substituted mixed ternary transition metal ferrite of the formula A1−xBxRyFe2−yO4. The nanocomposite has a high dielectric constant, low dielectric loss, both stable over a wide frequency range. These properties may make the nanocomposite desirable for applications in microelectronic devices, sensors and antennas.

摘要： A magnetoelectric nanocomposite (MEN) is described. The MEN are used as a colorectal cancer treatment. The MEN includes a shell having at least one ferroelectric compound and a rare earth (R) metal doped spinel ferrite nanoparticle (SFNP) core, of a formula of CoxMn1-xR2-yFeyOz wherein x= 0.1-0.9, y = 1.90-1.99, and z = 3-5; and R is at least one rare earth metal selected from the group consisting of cerium (Ce), europium (Eu), gadolinium (Gd), terbium (Tb) and thulium (Tm). A method of making MENs is also provided.
