Disordering of small metal particles in a scanning transmission electron microscope
Small metal particles in the range of a few nanometers in diameter are seen to progressively disorder when the 100 keV electron beam of a Scanning Transmission Electron Microscope (STEM) is held stationary on the particle. The diffraction pattern of the individual particle is seen to progress from …

Structure and melting of small metal particles observed by stem microdiffraction
… (Au, Au-Ag, Pt) and vapor deposited (Cu) metal particles •1040 Awas swdied by electron microdiffraction in a S1EM. A CCD array recorded the microdiffraction pattems with high sensitivity and dynamic range, and low noise Microdiffraction pattems were classified according to whether they had …

Structure and melting of small metal particles observed by stem microdiffraction
… (Au, Au-Ag, Pt) and vapor deposited (Cu) metal particles $\approx$10-40 A A was studied by electron microdiffraction in a STEM. A CCD array recorded the microdiffraction patterns with high sensitivity and dynamic range, and low noise Microdiffraction patterns were classified according to …

Heterogeneous combustion of condensed particles in transition regime
… are performed for combustion of zirconium particles of different sizes. Temperature and oxygen concentration profiles are calculated and compared to those predicted by the continuous medium transfer model. It is shown that for particles in the range from 100 nm up to 30 gm heat and mass …
