The new molecules in the form of microspheres 89Y2O3 obtained by modified INCT sol-gel method for liver cancer treatment

In the Sol-Gel Laboratory (INCT) on the basis many years of experience in the preparation new generation of ceramic materials has been taken study for preparation microspheres Y2O3 to treatment hepatic malignancies cancer. Using a combination of patented processes (INCT Process, patent PL-83484 and Complex Sol-Gel Process-CSGP, patent PL-172618) in one method for the production of spherical particles with diameters 10 to 100μm obtained 89Y2O3 microspheres (decision to grant a patent by the Polish Patent Office of November 19, 2014 for patent application P-394645 in 2011). Microspheres after fractionating were study to physicochemical properties and were tested stability in the environment physiological saline, serum and blood. In order to obtain the properties of the radiopharmaceutical 89Y2O3 microspheres were irradiated in the reactor Maria in the reaction 89Y (n, γ) 90Y

Superconducting and Microstructural Properties of (Mg+2B)+MgB2\text{}_{2}/Cu Wires Obtained by High Gas Pressure Technology

In order to improve the overall critical current characteristics of Cu sheathed in situ MgB$\text{}_{2}$ wires a special architecture of the wire, and processing parameters were used. The study presents the influence of the ex situ MgB$\text{}_{2}$ chemical barrier between ex situ core and Cu, suppressing the reaction of Cu with Mg. Wires, doped with 10 at.% SiC of 18 nm average grain size, were fabricated from MgH$\text{}_{2}$ and B or from Mg and B powders, using the powder-in-tube method. The methods of rotary swaging or drawing were used as the alternating wire-forming processes. The samples were annealed under high Ar gas pressure (hot isostatic pressing) at 750ºC and 1.0 GPa for 15 and 30 min. A significant difference in Cu distribution across the wires for a long and short time of sintering was observed. The formation of microstructure in the powder-in-tube process and the relationship between the microstructure and critical current density J$\text{}_{c}$ values, are discussed in this paper
