Study of Non-Isothermal Crystallization Kinetics of Biodegradable Poly(ethylene adipate)/SiO2 Nanocomposites
Poly(ethylene adipte) and poly(ethylene adipate)/silica nanocomposite (PEAd/SiO2) containing 3 wt. % SiO2 were prepared by an in situ method. The examinations on the non-isothermal crystallization kinetic behavior have been conducted by means of differential scanning calorimeter (DSC). The Avrami, Ozawa, and combined Avrami and Ozawa equations were applied to describe the crystallization kinet...
متن کاملNon-isothermal Primary Crystallization Kinetics of the Amorphous Fe85.3B11P3Cu0.7 Alloy
In the present research, the primary crystallization kinetics of the amorphous Fe85.3B11P3Cu0.7 alloy was analyzed using non-isothermal DSC measurements. The average and local activation energies, Ea, were determined by different isokinetic and isoconversional methods. The results obtained for activation energy in this research, show that due to the complexity of the primary crystallization pro...
متن کاملPreparation and Characterization of Hydroxyapatite/Alumina Nanocomposites by High-Energy Vibratory Ball Milling
Hydroxyapatite/alpha-alumina composites were prepared by means of high-energy vibratory ball milling. The effect of the addition of alumina, from 5 to 25 wt%, was investigated. x-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR) results indicated thathydroxyapatite andaluminawere themajorphases aftermechanicalmilling and only small peak shifts were observed. Transmission...

متن کاملPhonon density of states of nanocrystalline Fe prepared by high-energy ball milling
We performed inelastic neutron scattering measurements on nanophase Fe powders prepared by high-energy ball milling. Neutron energy loss spectra were measured for two states of the material: ~1! as milled, when the material had a characteristic nanocrystallite size of 12 nm; and ~2! annealed, when the material had a characteristic crystallite size of 28 nm. The longitudinal peak in the phonon d...
