“Edge of the Nano-Forest” by Stefano Marinoni (LMSC).
Congratulations!
Edge of the Nano-Forest, Stefano Marinoni (LMSC) September/October 2025
A dense, shadowed forest formed during plasma etching of a Gallium Nitride sample. The tilted SEM view captures its edge, where the trees thin out, revealing the bare substrate beneath. Microscope: SEM Merlin.
Flowers on desert, Shuqing Song (LAS) July/August 2025
This is a flower shaped ZIF crystal. Microscope: SEM Teneo.
Golden Domains, Pierpaolo Ranieri (INE) May/June 2025
This TEM image reveals the intricate ferroelectric domain structure of a potassium niobate lamella following a thermal cycle. The pattern is false-colored in golden yellow to highlight the dynamic microstructural beauty of this functional material. Microscope: TEM Talos.
Red House on Cracked Green Earth, Qiucheng Xu (LSCI) March/April 2025
False‐colored SEM micrograph of a carbon gas diffusion electrode (GDE) surface, acquired on a field‐emission scanning electron microscope at 10 kV with the sample stage tilted ~25° to accentuate the microporous layer’s topography. The carbon surface is rendered in green and ochre tones, deep crevices appear in dark brown, and an isolated particulate feature has been false-colored bright red to resemble a small house perched above the cracked “landscape.” Microscope: SEM Gemini.
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.

“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.

Dendritic growth of copper during electrodeposition resembling blooming of flowers. Microscope: SEM/FIB CrossBeam.
Roaring Fire, Yan Meng (FIMAP) 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.
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.

Seascraper, France Bourely (LNMC) 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.
