Cahn Prize - A prestigious prize for researchers in materials science

The Journal of Materials Science is proud to award the Cahn Prize for materials research. 

The 2022 monthly finalists' papers are free to read below.

Cahn Prize

The Cahn Prize has been named in honor of the Journal’s founding editor, the late Professor Robert Wolfgang Cahn.

Each month the Editors select a paper published in that month’s issues via a rigorous nomination and voting procedure. The winning paper is selected from the twelve finalists by a separate panel of distinguished materials scientists. 

The authors of the winning paper receive an award of $5,000.

The Journal of Materials Science is proud to award the 2021 Cahn Prize for materials research to the March finalist:

Dislocation-based crack initiation and propagation in single-crystal SrTiO3
Xufei Fang, Kuan Ding, Christian Minnert, Atsutomo Nakamura & Karsten Durst 

Characterising deformation and cracking in ceramics is crucial to better implement them into small-scale functional devices. In this article, the interpretation of nano-indentation experiments in strontium titanate single crystals, which result in slip planes and cracks, is combined with a discussion and demonstration of dislocation theory. The authors skilfully weave both experiments and fundamental dislocation analysis to address important aspects of the mechanical properties of materials and reveal how deformation occurs in this ceramic.

“We are really excited about winning the 2021 Cahn Prize, and it is certainly a great recognition of our ongoing studies on dislocations in ceramic oxides,” said Dr. Xufei Fang, “By understanding the critical conditions for dislocation-induced failure in functional oxides, we aim to set a framework within which we can focus on engineering dislocation-tuned plasticity to boost the functionality, for instance, ferroelectric/dielectric properties.”
