Looking for advanced tomography data to test an algorithm? Look no further!
 
We've made 3D nanomaterial data public and open:
http://www.nature.com/articles/sdata201641#data-citations

"Electron tomography in materials science has flourished with the demand to characterize nanoscale materials in three dimensions (3D). Access to experimental data is vital for developing and validating reconstruction methods that improve resolution and reduce radiation dose requirements. The datasets represent the current limits of experimental technique, are of high quality, and contain materials with structural complexity..."

A review article I co-authored with +Gang Ren​ and published in Advanced Materials on electron tomography arrived today. Its nice to see an article in print after years of only receiving digital copies.

We just published a new paper on atomic resolution electron tomography in Nature Materials. This is a big step forward in the capabilities of 3D imaging at the atomic scale. I hope you're happy Dr. Feynman.

Our method for 3D reconstruction of nanoparticles in liquid solution using Graphene (named SINGLE) was also written up in EETimes. 
Researchers at Lawrence Berkeley National Laboratory are using a monolayer of graphene as a see-through lens-like cap -- called a graphene liquid cell -- to create a new imaging system that can see the individual atoms in a single nanoparticle while it is still in solution.

If you want to know where I work you can check out this webcast. TEAM I at NCEM will be one of the facilities showcased. The microscope is being fixed and in pieces right now, but it should be cool to see.

A great program for 3D visualization of tomography data getting even better. Check out the newest release of tomviz.
 
Check out the latest release of tomviz, now with even more tools to enable reconstruction of your data, some experimental support for ITK, and much more. We also hosted a small hackathon at +Kitware headquarters, it was great to spend the day hacking with our collaborators from +Cornell University!
Kitware hosted a small hackathon yesterday with guests from Cornell, and released tomviz 0.7.0

Our paper on 3D tomography with 19 picometer precision was published today in Nature Materials. We find the 3D coordinates of thousands of atoms, identify a point defect and calculate the full 3D strain tensor. This work pushes the forefront of 3D materials analysis.

A nice update (0.6.0) to the opensource 3D visualization platform called Tomviz was released recently. After some testing I really like the improvements in features and stability. Tomviz is highly recommended for 3D tomography visualization!
 
Check out the latest release of tomviz, this post highlights major new features such as improved rendering, support for more file formats, and improvements that facilitate sharing analysis work flows.
Our tomviz developers are at the M&M conference (microscopy and microanalysis) this year

Recent work of mine in collaboration with +Jungwon Park, +hans elmlund and many others was recently published in Science. We were successful in reconstructing the shape of Pt nanoparticles at atomic-scale resolution in liquid. We combined three state-of-the-art techniques (sample preparation, TEM imaging and processing) to accomplish this. Our technique (called SINGLE) should open up new ways to image the 3D structure of very small structures in their native environment (like liquids) that was previously impossible.
Looking at teeny tiny platinum particles Electron microscopy is a powerful technique for taking snapshots of particles or images at near-atomic resolution. Park et al. studied free-floating platinum nanoparticles using electron microscopy and liquid cells (see the Perspective by Colliex). Using analytical techniques developed to study biological molecules, they reconstructed the threedimensional features of the Pt particles at near-atomic resolut...

I was asked to share some of my research at an event called Eight Big Ideas hosted by LBNL as part of Science at the Theater in Berkeley, CA. I was one of 8 scientists given 8 minutes to break down one idea for a general audience. The event was great and I really enjoyed the opportunity to speak at an event like this. My speech "Imaging Atoms in 3D" starts at about the 19:30 mark, but the other speeches are very interesting, too!

I love that comic. They almost me take it out but allowed it in the end.

Story
Introduction
I obtained my Bachelors of Science from the School of Applied and Engineering Physics at Cornell University in 2003 after also completing internships with the NNIN and Sandia National Laboratories. I remained in Ithaca, NY at Cornell University to pursued my doctorate (PhD) in applied physics working with Dr. David Muller. My main research activities involve scanning/transmission electron microscopy (S/TEM) with a focus on three-dimensional electron tomography. Electron tomography is a technique to reconstruct 3D structures from a series of 2D images (similar to a medical CAT scan) thus allowing quantitative investigation of buried features, such as wire barrier layer thicknesses and material voids. I developed the incoherent bright field (IBF) STEM imaging technique to reconstruct ultra-thick cross-sections of nano-scale semiconductor devices. Another goal of my research is a microscopic understanding of the bulk and interfacial properties of copper wire barrier materials for improvements in barrier thickness and adhesion. This interface has proven a major source of failure in integrated circuits affecting the yield and lifetime of modern computer chips. Electron energy loss spectroscopy (EELS) allows spatially resolved measurements of a material's local chemistry and electronic structure with atomic accuracy.

I graduated from Cornell University with my PhD in applied physics in June 2009. I am continuing my electron microscopy research at Lawrence Berkeley National Laboratory with the National Center for Electron Microscopy. I am currently a collaborative postdoc at NCEM and am responsible for starting a user-based tomography program. I am currently working with the TEAM 1.0 triple corrected (Image, probe, chromatic) microscope outfitted with the TEAM tilt-rotate stage.

I have brought my dog to Happy Hounds numerous times and the service always impresses. They have play groups for every size of dog, and the staff is very attentive. My dog loves other dogs and plays all day long. She always comes home happy and completely worn out from all the activity. This is a great doggy daycare. Highly recommended!
