This image shows the three dimensional structure of glial fibrillary acidic protein in a human glioblastoma astrocytoma cell. The colour represents the axial position. The image is 15x15x1 µm. This image is obtained using super resolution microscopy. Here the blinking of fluorescent molecules is used to measure only the signal originating from a single molecule. A cylindrical lens creates an astigmatism that allowed us to obtain both lateral and axial position of the molecule. - Rolf Harkes

Koolstof ‘nanotrees’ in verschillende grootte en stage van groei. De nanotrees groeien in een random vorm, onder invloed van de hoog-voltage electronenbundel (200 kV) van de Transmissie Electronen Microscoop, uit een plakje puur koolstof. Het puur koolstof is zichtbaar als de donkere cirkel in het midden, en ligt op een 10 nm dunne, amorfe SiN (silicon nitride) window. Koolstof nanotrees zijn een vorm van koolstof nanotubes, die zich vertakken in 3 dimensies tijdens de groei. - Marien…

The picture shows a microscope image of micrometer-sized flowers self-assembled from silica particles equipped with sticky “DNA-glue". The core of the flowers are 1 micrometer-sized silica particles functionalized with a DNA strand with a green dye. The petals of the flowers consist of 2 micrometer-sized particles, containing the complementary DNA strand with a red dye. Using these particles in different concentrations, beautiful flower-like structures form due to the DNA strands.

Scanning electron microscopy image of micron-sized particles, so-called colloids, with a smiley face on one side of the sphere. The particles are made by solidifying soft spheres, which induces buckling of the outside of the shell resulting in dents. In this particular case, the dents form smiley faces on al particles! These particles are used in self-assembly experiments to obtain larger structures with novel physical properties.

Lipid membranes mediate a force between membrane proteins. In this confocal microscopy image, six spherical lipid membranes together with many 0.001 mm sized particles can be seen. Several of these particles are attached to the membranes: these particles attract each other through the membrane deformation they induce.

Einstein-de Sitter space is named after its discoverers and describes a universe that contains only pressureless matter, without spatial curvature and without a cosmological constant. Small perturbations in the pressureless matter clump together because of gravity and form a random cosmic web. Creation of such universes on a computer is important for obtaining a better understanding of the theory of gravity and the origin of structure. - Wessel Valkenburg

Het gaat hier om een microocube, liggend tussen Cobalt-nanoparticles. De nanoparticles zijn wat ronder van vorm, met verschillende oriëntaties, terwijl we de microcube hier precies edge-on zien. Door de hoge resolutie Trasmissie Electronen Microscoop (HRTEM) kunnen we gemakkelijk de deeltjes op atomaire schaal bekijken. - Marien Bremmer

Technological advances call for functional design. As a result, materials with unusual properties are in increasing demand. So-called metamaterials behave very differently from traditional substances such as wood or concrete. - Anne Meeussen

Still life of diffraction patterns created by KOH etched square holes in Gold on Silicon Nitride. Image taken by an optical microscope with black and white sensor. Kandinsky would be proud! https://upload.wikimedia.org/wikipedia/commons/f/f0/Vassily_Kandinsky,_1923_-_Circles_in_a_Circle.jpg - Maarten Leeuwenhoek

The magnetic field in a plasma can form a stable structure where the field lines lie on donut-shaped magnetic surfaces. When you give the structure a kick, perturb it, some of the donuts break apart into tubes, called magnetic islands. This image shows for each magnetic surface how quickly the field lines wrap around the torus. When the field lines close the surfaces are likely to break up, as you can see in the image, where 2,3 islands an 5,8 islands can be seen.
