• field emission scanning electron microscope was used to observe the morphology at an accelerating voltage of 10 kV. The crystallinity (Tc) and melting temperature (Tm) were measured by DSC. Results showed a significant improvement in mechanical and thermal properties in accordance with the addition of

• electron microscope (FE-SEM) was used to observe the morphology of the FBC/Mater-Bi composites. All samples were coated with gold and observed by using an accelerating voltage of 10 kV. Differential scanning calorimetric (DSC) experiments were carried out by using a Perkin Elmer Pyris DSC-7 calorimeter

• amount of amorphous carbon due to the fragmentation of the organo-metal [(CH3)3Pt(CpCH3)], used as precursor for Pt deposition, can be reduced by using electron-beam irradiation with a low accelerating voltage as a post-deposition treatment. Results and Discussion 3D distribution of Pt nanoclusters

• decomposition and further deposition is induced by interaction between electrons and materials, deposition can be tailored by tuning the accelerating voltage of the electron beam to control their transmission through a fixed thickness of target so as to realize the deposition on one or more facets. Stripe

• is studied by changing the beam accelerating voltage (primary energy, PE) and dwell time, whereas the beam current is not varied in the current study. Figure 6 summarizes the deposition of Pt for an increasing PE of 1 kV, 3 kV, 5 kV, 10 kV, 15 kV and 30 kV in each row. For each PE, different dwell

• determined by transmission electron microscope (TEM, JEOL-2100) with an accelerating voltage of 200 kV. For TEM experiments, the specimens were prepared by deposition of a dilute solution of the colloid onto a carbon-coated copper grid and drying at room temperature. Thermogravimetric (TG) measurements were

• diffraction (XRD) measurements were performed in a Bruker D8 diffractometer with an accelerating voltage of 40 kV and a current of 40 mA, with Cu Kα radiation. The 2-D-SAXS measurements were carried out by using a Nonius rotating anode setup (Cu Kα radiation with λ = 0.154 nm) featuring a three-pinhole
