“Sea-lenium Waves” by Laurène Tribolet (FIMAP).
Congratulations!

January/February 2025
A defect in a cured transparent resist created wrinkles, forming wave-like structures. During the dewetting of a thin selenium film, droplets formed and settled on the surface, appearing to float on the waves. Microscope: SEM Gemini. 1/1

2024 winners gallery

November/December 2024
“Seeing is believing.” This freely suspended structure was fabricated by two-photon lithography (TPL), followed by atomic layer deposition (ALD) of Ni on a SiN membrane frame without a membrane. The free-form design achieved by TPL and the 3D conformal coating by ALD are being seen. Microscope: SEM Gemini. 1/6

September/October 2024
Ni foam support used in water splitting that looks like a sad, hanging ghost. Microscope: SEM Gemini. 2/6

July/August 2024
Salt dendrites with polymer nanoparticles. Observed by TEM. Microscope: TEM Talos. 3/6

May/June 2024
The image looks quite like a goldfish with a human face. Microscope: SEM Teneo. 4/6

March/April 2024
Gas Diffusion Electrode after electrochemical CO2 reduction. Microscope: SEM Teneo. 5/6

January/February 2024
An undesirable air bubble created a hole in a flat substrate, which turned into a dark moon hiding the sun in a starry sky after the dewetting of a thin selenium film. Microscope: SEM Gemini. 6/6

2023 winners gallery

November/December 2023
Thin layer of selenium dewetted into beautifully spread droplets on winding resist valleys resulting from unwanted buckling. Microscope: SEM Gemini. 1/6

September/October 2023
Dendritic growth of copper during electrodeposition resembling blooming of flowers. Microscope: SEM/FIB CrossBeam. 2/6

July/August 2023
Polyvinylidene Difluoride (PVDF) polymer thin film after thermally drawing. This soft and plastic film under microscopy looks like fire burning with flames. Microscope: SEM Gemini. 3/6

May/June 2023
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. 4/6

March/April 2023
For 2023 St-Patrick’s day: an Irish fiddle made of the stacking of Cu cubes and few Cu rods. Microscope: TEM Spirit. 5/6

November/December 2022
Freeze-dried polymeric core shell particle. Microscope: SEM Gemini. 1/6

September/October 2022
Potassium niobate lamella prepared using focused ion beam. As an effect of the bend contours a spider appears on the surface. Microscope: TEM Talos. 2/6

July/August 2022
Nothing better than a nano ice cream during a hot summer afternoon. Composed of randomly distributed Cu nanocrystals around a Cu rod. Microscope: TEM Tecnai G2 Spirit Twin (Sion). 3/6

May/June 2022
A spherical inclusion sitting on a chemically etched iron surface. Microscope: Gemini SEM 4/6

March/April 2022
Germanium monsters arose at the bottom of a Silicon ocean from a Ion Beam Etching gone wrong. They are waiting with their gaping jaws for the next pray passing by. Microscope: SEM/FIB NVision. 5/6

November/December 2021
Differential phase contrast (DPC) imaging of freestanding 2D materials with thickness variations. Microscope: TEM Themis 1/5

September/October 2021
Anaglyph made from tilt-less stereo-pair STEM images of dislocations in TiAl alloy, stereo-angle approximately 2 degrees. Best viewed with 3D glasses. Microscope: TEM Osiris. 2/5

May/June 2021
A failed yet beautiful attempt towards the optimization of poly(triazine imide) membranes. We deposited single-layer poly(triazine imide)nanosheets on a porous alumina support. Microscope: SEM Teneo.

March/April 2021
Formation of silico-alkali-calcareous “hedgehogs” in concrete immersed for 3 months in an alkaline solution. Microscope: SEM Merlin. 4/5

January/February 2021
Phytoplancton emerging from a pore on the skeleton of the mediterranean sea urchin Paracentrotus lividus. The function of the many interconnected pores is to allow the passage of adhesive tube feet, mainly for locomotion. This endoskeleton, enclosed by an epidermis, and spines, is called a test. It is famous for its beautiful symmetry, and is mostly made of calcite and magnesite. Its shape is effective at distributing stress evenly over the surface. Marine echinoderms can be studied for their numerous biomimetic applications. Gold coated, and photographed at 2kv on a Gemini-SEM 300. 5/5
