Iron (oxy)hydroxides precipitating on the bacterial cells. Microscope: SEM Gemini.
The sun [electron beam] casts its golden rays over the rugged terrain, where various shapes and sizes of ‘[micro-] boulders’ dot the [iron oxide] landscape. Some are round, others are sharp and angular, but all have a story to tell. They have witnessed the passage of time, erosion, moss, and lichen growth. They stand as silent sentinels, creating a contrast with texture and depth to the scene. The photo invites the viewer to explore and discover more. [– The SEM image of iron oxide micro-boulders– ] Microscope: SEM Gemini.
The space left after bacterial cell ‘bursting’ out of the cast formed by iron precipitating on the cell outermembrane. Iron (oxy)hydroxides precipitation was proposed to be one of only a few ways to preserve the cells in the fossil record. Can we use them to search for past life on Mars?

The functional group sits in the middle of pore in the oxygen-functionalized porous graphene. Microscope: TEM Themis.
SEM image of a chemically synthesized gold crystalline flake exhibiting a fractal-shaped defect, reminiscent of von Koch fractal. Perhaps, the crystal was unlucky to get a defect during the growth as it was labelled with the unlucky number 13? Microscope: SEM/FIB CrossBeam.

Unwanted wrinkle in a porous nanocrystalline graphene membrane. Microscope: FEI Teneo SEM.
What a nostalgia of those days spent playing with wooden blocks on the floor! But wait, who left these toys lying around in the SEM? Silver nanoparticles oberved with SEM Gemini 300. False colors added with Photoshop. Microscope: Zeiss GeminiSEM 300.
From a distance (low magnification) the image seems to contain polymer fiber peaks formed at the junction where fibers from different directions meet. A closer analysis reveals what appears to be molten polymer of the top fibers fusing or spreading over the cooled down fibers below them. The technique used here is called melt electrowriting (MEW) and permits controlled deposition of fibers to create different designs. Poly Capro Lactone is the polymer used and the samples have not been coated. Microscope: Zeiss GeminiSEM 300.
‘Cause you’re a sky, ’cause you’re a sky full of… dislocations! Wasn’t that the famous Coldplay’s song? The image represents a thin film of Ge on a Si substrate and it was made by aligning the electron beam to the z-axis of the sample with a little tilt (ECCI – electron channelling contrast imaging). Microscope: Zeiss Merlin SEM.
The SnO2 films were deposited on FTO/glass substrates by using chemical bath deposition method with (a) 3-hour, (b) 4-hour, (c) 5-hour and (d) 6-hour deposition time. The working mode of SEM Gemini machine is InLens with 1.0 kV and magnification of 30.00 K. For inset images, the working mode is InLens with 1.0 kV and magnification of 40.00 K. Prof. Paul J. Dyson agrees to authorize CIME to publish it on CIME websites. Microscope: Zeiss GeminiSEM 300.
