Irvine, Calif., March 11, 2021 – Catastrophic collapse of materials and structures is the inevitable consequence of a chain reaction of locally confined damage – from solid ceramics that snap after the development of a small crack to metal space trusses that give way after the warping of a single strut.

Irvine, Calif., Jan. 11, 2021 – Often admired for their flawless appearance to the naked eye, crystals can have defects at the nanometer scale, and these imperfections may affect the thermal and heat transport properties of crystalline materials used in a variety of high-technology devices. Employing newly developed electron microscopy techniques, researchers at the University of California, Irvine and other institutions have, for the first time, measured the spectra of phonons – quantum mechanical vibrations in a lattice – at individual crystalline faults, and they discovered the propagation of phonons near the flaws.
High-performance fibres that have been exposed to high temperatures usually lose their mechanical properties undetected and, in the worst case, can tear precisely when lives depend on them.
