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 winner will be announced at the MRS Fall conference.

The 2020 monthly finalists' papers are free to read below.

Cahn Prize

The Cahn Prize is 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.

You can read more research at the Journal of Materials Science.

The winner of the 2020 Journal of Materials Science Robert W. Cahn Best Paper Prize (the Cahn Prize) is our February finalist:

Highly stretchable, breathable and negative resistance variation textile strain sensor with excellent mechanical stability for wearable electronics
