Co–Ti ferrite (Co 1+x Ti x Fe 2−2x O 4 , 0.2≤x≤0.5) nanoparticles with average diameters ranging from 6 to 12nm were produced by a wet chemical method. The imaginary parts of the AC magnetic susceptibility χ″, which is the most dominant value dependent on the thermal energy generated in the magnetic nanoparticles, were measured for samples placed in a 1-Oe, 100-Hz AC...
The ionization ability of manganese oxide nanoparticles were studied in this paper. Manganese oxide nanoparticles were prepared by our novel method as reagents for the laser desorption/ionization mass spectrometry (MS) analytes. The nanoparticles were characterized by X-ray diffraction, Fourier transform infrared spectra and DC magnetization.
CoTi-Zn ferrite nanoparticles were produced in order to carry out hyperthermia treatment and ac magnetic susceptibility measurements were performed. From the analyses of temperature and frequency dependence, Ne??el relaxation in this system was concluded.
Structural properties of various kinds of room-temperature synthesized C60 fullerene nanowhiskers were investigated by TEM and XRD. The C60 nanowhiskers prepared by use of toluene lost their initial solvated hexagonal structure faster than the C60 nanowhiskers prepared by use of m-xylene. The hexagonal structure of C60 nanowhiskers prepared by use of toluene was stabilized by adding C60[C(COOC2H5)2]...
