Changes in microstructure of a shape memory alloy (CuAlNi single crystal)
Changes in microstructure of a shape memory alloy being heat treated and also mechanically deformed. A CuAlNi single crystal (2H orthorhombic phase ) is compressed (vertical axis) at room temperature, causing activation of two sequential twinning deformations. As austenite, the crystal is cube-shaped, whereas in the martensite form it is sheared. Six different sheared martensite crystals, having well - defined prism shapes (three of which appear in this video), can be created by pressing on 3 di
How the Arctic Ecosystem Might Change
In this video segment adapted from the National Film Board of Canada, learn why the unique Arctic ecosystem may be replaced if global warming continues to melt sea ice.

Transient Heat Conduction - Lumped Capacitance from the course Heat Transfer
This course covers transport processes of mass, momentum, and energy from a macroscopic view with emphasis both on understanding why matter behaves as it does and on developing practical problem solving skills. The course is divided into four parts: introduction, conduction, convection, and radiation.
