3D atomic imaging of nanoparticles
— a new technique

February 24, 2011

Image and atomic reconstruction From the abstract: Although atomic-resolution electron microscopy has been feasible for nearly four decades, neither electron tomography nor any other experimental technique has yet demonstrated atomic resolution in three dimensions. Here we report the 3D reconstruction of a complex crystalline nanoparticle at atomic resolution. To achieve this, we combined aberration-corrected scanning [...]

Atomic Layer Deposition
for Atomically-Precise Crystal Fabrication (2)

February 16, 2011

The American Vacuum Society writes to announce ALD 2011, the 11th International Conference on Atomic Layer Deposition: Atomic layer deposition (ALD) is a fast-moving frontier, profoundly impacting diverse applications and gaining momentum for industrialization and manufacturing, while leaving plenty of room for new science and innovation…. ALD is receiving attention for its potential applications from [...]

Semi-synthetic implants of semi-tissue

February 3, 2011

There’s been striking progress in not-quite-tissue engineering, and the technique brings several strong practical advantages over methods that yield products more like genuine tissue. The problem situation looks like this: Some tissue structures don’t regrow, or regrow slowly; grafts of tissue from another person often lead to rejection; grafts of tissue from a patient’s own [...]
