Bring better products to market faster with Aduro™

Aduro™ is a scalable platform for quantitative electron microscopy. The systems revolutionize the analytical capabilities of electron microscopes by providing the ability to do in situ work at temperatures up to 1200 °C with atomic resolution. Until now, no commercially viable solutions have existed that enable real-time, dynamic thermal studies in a fast, versatile, high-resolution and easy-to-use package. With its revolutionary capabilities, Aduro™ allows you to develop products faster, understand products better and spend less money on research. Because Aduro™ is compatible with new and existing equipment, you can start improving your return on capital today.

Get results with Aduro™

Entirely new means of investigating materials are now available. Success stories with Aduro™ include: studying platinum catalysts at 1000 °C with atomic resolution, analyzing grain growth in thin films at temperatures in excess of 600 °C, and constructing particle size versus temperature dependence relationships in a single microscopy session.

Numerous results achieved with Aduro™ are being published, a sample of papers that were presented at Microscopy and Microanalysis 2008 where Aduro™ was officially announced is described below.

Scientific Talks

"Study of Pd/ZnO Nanocatalysts for Hydrogen Production"; J. Liu, J. Wang and L. F. Allard

Pd supported on ZnO is a potential catalyst for hydrogen production, and the synthesis-structure relationships of a Pd/ZnO model nanocatalyst were studied. Using a STEM equipped with Aduro technology, it was found that PdZn nanoparticles were formed after the Pd/ZnO precursor materials were heated in situ at 500°C for about 20 minutes. After in situ heating at about 800ºC for one hour, individual monomers and small clusters of Pd were also observed along with the PdZn nanoparticles.

"In-situ Z-STEM Imaging of Chemical Ordering in FePt Magnetic Nanoparticles"; J.E. Wittig, J. Bentley, L.F. Allard, M.S. Wellons and C.M. Lukehar

Monodispersed 3-10nm FePt nanoparticles have potential for future magnetic storage media, and understanding specific phase transformations is essential for their use as engineered magnetic nanostructures. The development of L10 order in individual FePt nanoparticles was investigated using STEM and Aduro technology.

The nucleation of the ordered structure was investigated for FePt nanoparticles at 400°C and 500°C. The onset of the ordering transformation for 5.2nm particles was observed in situ. At 400°C, indications of (110) superlattice planes were seen. At 500°C, the particle showed the formation of (001) superlattice planes with faceting of the (001) and (110) planes, and bright spots observed on the “Fe” planes likely indicate the presence of Pt anti-site defects. It is noteworthy that these results were not detected in XRD data.

Poster Sessions

"In-situ TEM Observations on the Sintering Process of Colloidal Gold Using an Ultra-fast Heating Stage"; M. Briceno, K. Hattar, John Damiano, David Nackashi, I.M. Robertson

The sintering of colloidal gold particles was studied using HRTEM and Aduro technology. In this study, the particles were heated to approximately 600°C, and the sintering process was recorded at an image rate of approximately 20 frames-per-second. During the sintering process, collisions occurred and this resulted in coalescence of particles. A sequence of HRTEM images taken over two minutes shows the formation of a neck between adjoining nanoparticles. Although the sintering of metallic nanoparticles on a support is often modeled in terms of “Ostwald ripening”, these results reveal a “neck growth” mechanism dominated by surface atom diffusion rather than “Ostwald ripening”.

Workshops

"PRISM: Practical Remote In-situ Microscopy"
presenter: Larry Allard
Location & time: 5:30pm Monday evening at the JEOL booth (#1027)

JEOL showed conference attendees how to remotely control the aberration-corrected STEM at ORNL with their software. The Aduro™ heating holder was used during the demonstration highlighting both the novel in situ science made possible by Aduro™ and the compatibilty of Aduro™ with even the most sophisticated instrumentation.
