Finding the cause of a fatal problem in rocket engine combustors

Rocket engines contain confined combustion systems, which are essentially combustion chambers. In these chambers, nonlinear interactions among turbulent fuel and oxidizer flows, sound waves, and heat produced from chemical ...

Swarms of robots could dig underground cities on Mars

Underground habitats have recently become a focal point of off-planet colonization efforts. Protection from micrometeorites, radiation and other potential hazards makes underground sites desirable compared to surface dwellings. ...

New insights into the formation of bulk metallic glasses

With the ability to produce metallic glass in bulk quantities, the distinct mechanical behavior of these materials has opened up new application opportunities. However, the poor room temperature plasticity of bulk metallic ...

Bioinspired materials from dandelions

Fields are covered with dandelions in spring, a very common plant with yellow-gold flowers and toothed leaves. When they wither, the flowers turn into fluffy white seed heads that, like tiny parachutes, are scattered around ...
