Aduro™ Application Notes

Annealing of Zirconia Alumina Nanostructure Observed In Situ

In situ imaging of nanostructures at high temperature to better understand the processes by which these structures are formed.

Ultra-high Stability Enables Atomic Resolution of Pt Catalysts at 1000˚C

Two different techniques for sample preparation with the Aduro™. Sample then imaged at 1000°C.

Secondary Electron Imaging of 3D Nanostructures at 750˚C

A hollow tube composed of three ALD layers is heated to 750°C and imaged continually. This minutes long dynamic process ended with the formation of two microtubes.

In situ heating of the precursor materials inside the TEM provided insights into the diffusion processes of molecules and atomic clusters, and how the PtSn nanoparticles evolved.

In Situ, Time-Resolved Electron Microscopy Analysis of Thermal-Induced Phase Transitions in Nanostructured Materials

In situ heating for 9 minutes at 500°C reveal the shrinking of voids, surface rearrangement of the Fe2o3, growth of the larger Au nanoparticles and the very fine Au species coalesced into larger particles.

Atomic-scale Imaging of Redox Processes in Ceria Nanoparticles from Solid Oxide Fuel Cells

Atomic-scale structure images were recorded and analysis of the reduced phase by fast Fourier transform (FFT) analysis confirmed the appearance of extra spots in diffraction patterns as evidence for the formation of a superstructure during the high temperature reduction.

Atomic-scale Imaging of Redox Processes for Photovoltaic and Hydrogen Storage Materials

The simulation of high temperature/pressure gas reactions of catalysts using the Aduro™ system.

In Situ high-angle annular dark-field (HA-ADF) imaging demonstrates the dynamics of the catalyst-support interaction.

MWCNT-encapsulated FE3C undergoes a plastic flow and a dynamic geometric tansformation to fill the entire cavity within the MWCNT structure.

In Situ measurement of IBID and EBID of metal contacts deposited directly onto the 4 Au leads on the Aduro™ Electrical E-chip.

EBID and IBID was used in tungston nanowire formation to further study atomic deposition techniques and its effect on E-chip membrane integrity.

The deposition-precipitation of Pd was done by dipping the ZnO nanobelts into an aqueous solution containing Pd(NO3)2 as precursor salts, which were reduced by the TEM electron beam.

The specimen was imaged at room temperature and EDS spectra were collected. The specimen was subjected to multiple heat cycles and returned to room temperature for additional SEM imaging and EDS spectra collection.

The Aduro™ heating membrane changes temperature very rapidly (millisecond timescale), maintaining atomic resolution while heating, and minimizing thermal drift and settle time.

FePt magnetic nanoparticles were dispersed onto the ceramic membrane from a nanoparticle-hexane suspension and allowed to dry. The nanoparticles were heated to 500 °C and imaged after 1 min, 5 min and 15 min to observe phase transition.

Silver nanowires were drop cast on to the ceramic membrane from ethylene glycol and allowed to dry, An amorphous carbon layer was applied to the nanowire surface subsequent to synthesis. The experiment observed the thermal properties of the nanowires.

Aqueous gold nanoparticles were imaged with the Poseidon. Wet imaging unlocks the mechanisms that control dynamic processes such as nucleation, growth, and self-assembly.

The Poseidon™ GapSet™ E-chip™ design is ideal for imaging a continuous flow of liquid and for the injection of reagents into the system.

The GapSet™ E-chip™ channel design permits rapid exchange (~1 minute), of liquid within the sample chamber.
