Creation of Mo/Tc@C and Au@C and molecular-dynamics simulations.

The formation of middle- and/or high-weight atom (Mo, Au)-incorporated fullerenes was investigated using radionuclides produced by nuclear reactions. From the trace radioactivities of Mo/Tc or Au after high-performance liquid chromatography, it was found that the formation of endohedral and/or heterofullerene fullerenes in Mo/Tc and Au atoms could occur by a recoil process following the nuclear reactions. Furthermore, the Tc (and Au) atoms recoiled against β-decay remained present inside these cages.

Viscosity measurement of Xanthan-Poly(vinyl alcohol) mixture and its effect on the mechanical properties of the hydrogel for 3D modeling.

Biomodels made of poly(vinyl alcohol) (PVA) are demanded because they can represent the geometries and mechanical properties of human tissues realistically. Injecting and molding, commonly used in three-dimensional (3D) modeling, help to represent the blood vessels accurately. However, these techniques sometimes require higher pressures than the upper pressure limit of the dispensers for pouring in high viscosity materials; the material viscosity should therefore be lower.
