The macro- and microstructure of iron meteorites provide valuable insights into both the inner structure of our planet and the history of our solar system. High speed collision events in the asteroid belt send the meteorites careening toward Earth. The collisions produce unique deformation microstructures. With cooling rates on the scale of a few degrees per million years, iron meteorites can consist of crystal sizes on the order of meters prior to the collision events. These extremely slow cooling rates result in phase transformations occurring at conditions near thermodynamic equilibrium. Preserving meteorite fragments is important for future studies of phase transformations, material behavior at high strain rates, and the origin of the universe.

Scientists at the University of Southampton are to study the 3D architecture of healthy human tissues down to the nanometre scale (one billionth of a meter), to develop regenerative cell techniques for musculoskeletal repair. Funded by the Medical Research Council, the study will aid the team in the creation of accurate artificial scaffolds for growing replacement parts from stem cells for tissues such as cartilage and bone.

The scientific community and with it, every researcher, should be committed to sharing the aesthetics of the microworld, with as many people as possible. In the past it was mostly still shots of the specimen that were available. We thought it would be worth it to bring movement, color and lighting effects into the microworld and so developed a modular software called "nanoflight.creator"  with the goal of taking control of parameters like specimen movement, detector values, focus and colors of each detector channel in the Scanning Electron Microscope (SEM).

For a long time, the world of microanalysis was 2-dimensional. Recently, atom probe tomography (APT) and focused ion beam (FIB) serial sectioning (combined with other techniques) have become available for the 3D chemical analysis of small structures (<100 nm for APT and <20 µm for FIB). The article illustrates, that the modern silicon drift detector (SDD) technology used in energy dispersive spectrometry (EDS) on scanning electron microscopes (SEM) and in spatially resolved micro X-ray fluorescence (µ‑XRF) makes it quite simple to obtain 3D chemical data of larger samples.

Researchers working at the National Institute of Standards and Technology (NIST) have developed a new microscopy technique that uses a process similar to how an old tube television produces a picture-cathodoluminescence-to image nanoscale features. Combining the best features of optical and scanning electron microscopy, the fast, versatile, and high-resolution technique allows scientists to view surface and subsurface features potentially as small as 10 nanometers in size.

A unique chemical imaging tool readily and reliably presents volatile liquids to scientific instruments, according to a team including Pacific Northwest National Laboratory. These instruments require samples be held in a vacuum, which is often incompatible with hydrocarbons and other liquids. Designed and built at PNNL, this one-of-a-kind sample holder continuously pumps the liquid through a gold-coated microfluidic chamber. The extremely narrow channel provides high linear velocity at the detection window and helps overcome the liquids' tendency to vaporize. Instruments access the liquid via an open viewing port. Tests with electron microscopes and mass spectrometers prove the device can operate continuously for up to 8 hours. Further, the device handles complex liquids.
