Pressed for innovation: Hot imprinting of metal–organic frameworks enables optical-quality glasses

By Lisa McDonald / July 12, 2024

Shaping metal–organic framework glasses in their liquid state, which is the standard for conventional glass processing, has been an elusive feat. Researchers in Germany reported a process late last year for liquid handling of MOF glasses, and their new paper further elaborates on the potential of this process to create MOF glasses for real-world optical applications.

Circumventing insufficient slip systems: Near-surface dislocation mechanisms allow room-temperature deformation of polycrystalline ceramics

By Lisa McDonald / June 28, 2024

Plastic deformation of polycrystalline ceramics at room temperature is hindered by the lack of sufficient independent slip systems within the material’s structure. Researchers in Germany circumvented this limitation by focusing on deformation in the near-surface region, which demonstrates several useful dislocation mechanisms not available in the bulk region.
