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 ZnCeYbO, x=0.01-0.1, and where at least 90 wt. % of the dye is degraded during the irradiating of the aqueous solution.

Photocatalyst for the degradation of methyl orange dye

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 CoMnRFeOwherein 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.

Magnetoelectric nanocomposites and method of preparation thereof

A magnetoelectric multiferroic nanocomposite. The nanocomposite comprises a ferroelectric perovskite oxide and a rare-earth substituted mixed ternary transition metal ferrite of the formula ABRFeO. 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.

Method for forming rare earth-substitute nanocomposite

A method for forming hollow silica spheres by dissolving a hydrolyzable aryl silane in an aqueous solution of water and an acid to form a hydrolyzed silane solution, mixing the hydrolyzed silane solution with a hydroxide base to form a precipitate, and calcining the precipitate in a multi-stage calcination procedure that includes (a) heating to a first temperature of 180 to 240° C. with a first ramp rate of 3 to 10° C./min and holding the first temperature for 2 minutes to 2 hours, then (b) heating to a second temperature of 600 to 740° C. at a second ramp rate of 0.1 to 4° C./min, and holding the second temperature for 2 to 24 hours.

Hydrolytic and calcination method for forming hollow silica particles

A superconducting material includes YBaCuOand a nano-structured, preferably nanowires, WOdopant in a range of from 0.01 to 3.0 wt. %, preferably 0.075 to 0.2 wt. %, based on total material weight. Methods of making the superconductor may preferably avoid solvents and pursue solid-state synthesis employing Y, Ba, and/or Cu oxides and/or carbonates.
