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.

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.
