Indium islands

Physical Vapor Deposition (PVD) is used to deposit continuous thin films with thickness in the hundreds of nanometers range. For some metals with low melting temperature, deposition proceeds in “islands” of various sizes and shapes. This picture shows indium “islands” deposited by PVD on a...

Breaking waves

This is an optical microscopy image of a crack propagating left to right in a 1.5mm thick high strength steel sheet. This "wave" pattern, known as crack tip flipping, is the result of an oscillating stress state in front of the crack tip, causing the crack to oscillate on two 45° degree planes...

The ghost of the crystal cave

This image comes from SEM fractography of sintered iron oxides powders. The general context of the research was to study the use of iron as an efficient, CO2-free energy carrier, and in particular sintering of iron powders after combustion. Within the sample, this specific pillar structure was...

Coherence in chaos

The flow in the mixing chamber of a supersonic ejector generates two mixing layers between the driving supersonic flow and the entrained subsonic flow. It is those highly turbulent mixing layers that are responsible for the entrainment. The flow was simulated using the Argo code of Cenaero,...
