Biological SEM samples usually require a metal coating to avoid charging . However, a good knowledge of the properties and behavior of the samples offers ways to utilize internal electrical conductivity of biological samples for Scanning Electron MIcroscopy (SEM) examination without the need for metal coating. This not only simplifies the preparation, viewing and imaging. It also opens up new ways to examine natural, uncoated surfaces, for example compositional contrast imaging or for the study of adhesion effects.

PML researchers have devised an idea for determining the three-dimensional shape of features as small as 10 nanometers wide. The model-based method compares data from scanning electron microscope (SEM) images with stored entries in a library of three dimensional (3D) shapes to find a match and to determine the shape of the sample. The work provides a powerful new way to characterize nanostructures.

Scanning electron microscopes are extremely sensitive and even subtle movements going on around them can affect their accuracy. Vibration control tables already exist to dampen these sometimes barely perceptible disturbances. But now a new kind of isolation platform for the first time integrates sensors and actuators into the mount - resulting in a platform that is more cost-effective and compact than its predecessors. Its designers will be showcasing this new form of isolation at the Hannover Messe (Hall 2, Booth D13) from April 7-11.

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.
