Failure of Francis Scott Key Bridge provides future engineers a chance to learn how to better protect the public
Credit: Pixabay/CC0 Public Domain The cargo ship collision that destroyed the Francis Scott Key Bridge in Baltimore on March 26, 2024, is raising questions about just how much engineers can…
A first-ever complete map for elastic strain engineering
The “map,” or the phonon stability boundary, is a graphical representation that plots the stability regions of a crystal as a function of strain. This map helps scientists and engineers…
Paving new paths for sustainable construction
Formation of carbonate minerals in the pores and bulk matrix of the developed 3D printable material during carbon sequestration. The crystals are 3–5 micrometers in size and thus densify the…
