3010 In-Situ

AEME

The 300 kV JEOL 3010 offers greater specimen penetration than 200kV instruments, with significantly improved spatial resolution and probe forming capabilities. The side-entry stage allows ±45° tilt and can be operated with piezo-drift compensation. A flexible condenser system permits CBED, LACBED, and imaging with hollow cone and Koehler illumination. In addition to a standard film camera, a Gatan Orius CCD, and a Gatan 622 intensified TV camera and VCR are available for recording experiments at video rates. Specific capabilities include: high-resolution imaging at 2.1Å and ±40° tilt during simultaneous heating; very-high-resolution imaging at 1.7 Å and ±10° tilt during simultaneous heating; and high magnification Lorentz and Foucault imaging of magnetic samples. Various heating, mechanical testing and electrical biasing holders are available. (Instrument schedule and requirements: 8-1pm, 1-6pm, 6-12am; 2 weekday sessions and 1 weekend/evening session at a time.)

In-Situ Results

First direct observation of the nucleation of eutectic melting at a three phase junction of a Pb-Cd precipitate embedded in an Al matrix. (see also highlight)

 

Phase transformation of sputtered W thin film; image and composite diffraction pattern from different stages of the transition from beta to alpha W.

 

 

In-situ observation of the rapid genesis of a nanocrystalline nickel agglomerate (see white arrow) depicted by individual still frames extracted from a dynamic dark field video sequence. (A) t=0s, no grains in strong diffraction condition near the white arrow; (B) t=0.1s, a grain in strong diffraction condition with size about 6nm is visible; (C) t=0.2s, a group of grains in bright contrast, size about 28nm, is visible; (D) t=0.3s, now the group of grains has a nearly elliptical shape, dimensions 60nm by 35nm; (E) t=0.4s and (f) t=0.5s, the size of the group of grains increases to maximum dimensions of about 80nm by 60nm.
