DualBeam in situ 30kV STEM HAADF view of a GaN ultra-thin sample prepared in less than an hour, only by FIB, and using down to 1kV FIB polishing to allow for less than 2nm amorphized layers on each side of the lamella. Product: Helios NanoLab DualBeam
In the image are observed an elastic fibers. Specifically, it is an elastic polyester tape of masks commonly used in laboratories.

Pictured are the atomic-resolution structures of three amyloid polymorphs against a (falsely coloured) background image of the fibrils taken with a transmission electron microscope. Determining the fibril structures, and defining the major structural elements and interactions contributing to their hierarchical self-assembly, provides insight into the formation of polymorphic amyloid in a range of protein deposition disorders including Alzheimer’s and Parkinson’s diseases.

Shot peening of Ti-45Al-10Nb in air leads to partial amorphisation of the outermost layer and to the formation of a contaminant nanocrystalline (T, Al)N phase, presumably Ti2N. The figure shows dislocation recovery within a nano-crystalline grain embedded into the amorphous phase of the shot peened surface layer, as observed in situ. Three dislocations are marked by symbols. Stage (i): The isolated dislocation on the left hand side is relatively immobile. The two other dislocations are in a dipole configuration and propagate towards each other and are about to annihilate in stage (ii). Stage (iii) shows the situation after annihilation of the dipole dislocations; this is indicated by the continuous trace of the lattice planes. Observations made at room temperature with an acceleration voltage of 300 kV. It should be noted that the micrographs were sligthly compressed along the vertical direction in order to make the dislocations readily visible. The figure demonstrates the high electrical, thermal and mechanical stability of the instrument.

This cyanobacterium (Nodularia sp.) shows symbiotic bacteria (bacilli) intimately associated to the mucilage cover (extracellular polymeric substances) that serves as their food substrate. This cyanobacterium cannot be isolated without its symbiont.

Amarylis stigma (pink) with pollen grains (yellow) adhering to sticky glands on its surface. Some pollen tubes (olive green) carrying genetic material can be seen on top of the stigma. Imaged in low vacuum without prior dehydration. Dynamic focus and long working distance used for depth of focus.
