This scanning electron microscopy image shows the tip of a hard disk drive (HDD) read/write device, the magnetoresistive (MR) head assembly. This is the component that floats over the rotating magnetic disk inside a HDD and reads/writes the information recorded on it.
The slider (white rectangular piece, centered on the image) is what actually floats or slides over the surface of the magnetic disk, carrying the head at the correct distance from the medium (magnetic disk) for reading/writing. The complex forms over the surface of the slider (black and grey colors) are designed to maintain the same floating height above the disk surface, whether the slider is positioned above the inner or outer cylinders of the disk (the inner or outer part of the rotating magnetic disk). The linear speed of the rotating magnetic disk is different depending on the radial position of the MR head over the disk, so the air pressure between the slider and the magnetic disk is compensated thanks to this special designs to maintain the same reading/writing distance between the two parts and not lose performance or functionality.
The read/write sensors are the small straight pink lines over the black surface of the slider, on the right side of it.

Flakes of raw vermiculite concentrate are micaceous in appearance and contain interlayer water in their structure. When the flakes are heated rapidly at a temperature above 870° C, the water flashes into steam, and the flakes expand into accordion like particles. This process is called exfoliation, or expansion, and the resulting lightweight material is chemically inert, fire resistant, and odorless. In lightweight plaster and concrete, vermiculite provides good thermal insulation. Vermiculite can absorb such liquids as fertilizers, herbicides, and insecticides, which can then be transported as free-flowing solids.

A microscopical structure carved out of an aluminium alloy using an ion gun. In order to achieve a higher quality, a square-shaped area was first coated with platinum within the scanning electron microscope. In the next step the "face" was drawn within the program and the selected sites were milled away with the focused beam of Ga ions. The image was taken by using secondary electrons while the sample was tilted. This structure was created partly for training new SEM users but some images taken that day were also included in a science video about corrosion in space. youtu.be/GITtlkx2-Tw

Electropolishing of a copper sample in H3PO4 solution did not result in the desired mirror-like surface required for EBSD.
Investigating for the problem in the SEM it turned out, that a rough surface developed because oxygen-bubbles have formed on the anode during the electro-chemical process. At locations where bubbles have covered the surface, the removal of material was reduced and, for this reason, their shapes were etched into the material.

Abstract.
Residual stress patterns in the filter case from a polarising filter - used the filter plus another one under the subject to give the birefringence colours. True macro (approx. 2.7:1).
Sandia National Laboratories researchers Michael Chandross, left, and Nicolas Argibay show a computer simulation and an ultrahigh vacuum tribometer used in friction and wear testing, which are among the tools they use in a collaborative effort that developed a model to predict the friction behavior of metals. The goal is to understand friction and wear of materials at the most fundamental level.
