Exploring the mechanical behavior of MOF glasses

By Lisa McDonald / May 26, 2020

Metal-organic frameworks have immense potential in various applications but are difficult to synthesize in bulk. Fabricating MOFs in the glassy phase provides the necessary stability for bulk synthesis, and two new studies investigate the mechanical properties of these unique glasses.

3D-printed rocks improve understanding of fracture formation

By Lisa McDonald / April 21, 2020

The unpredictable nature of fracture formation in rocks makes it difficult to ensure reproducible measurements across different samples. Researchers at Purdue University 3D-printed gypsum rocks to overcome this problem and clearly investigate the effect of mineral fabric and layering on fracture formation.

Probing the mysteries of cracks and stresses

By / October 1, 2012

A dislocation in a crystal lattice, a disconnected region in its structure (represented by the array of atoms shown in blue) can separate from the rest of the lattice at a rate determined by the potential energy of the system, represented by the wavy surface. To the left, the higher potential energy (shown in red)…
