That's a nice question, @stychomithie.bsky.social! PAM tires could undoubtedly be more durable for rovers because they can adapt to their shapes and absorb shock energy much more efficiently. We would love to develop some tire prototypes alongside our helmet project - stay tuned :)

Thank you, Professor Muller, for kindly mentioning our work! Just a quick clarification: my PhD advisor was Prof. Mirkin. I was, however, fortunate enough to share many lovely moments with the late Sir Fraser, whose guidance and inspiration encouraged me to embark on this journey.

Thank you, Jake!! :)

[6/6] During my PhD at Northwestern Chemistry, I was inspired by the late Sir Fraser Stoddart to tackle “big problems.” His pioneering work on mechanical bonds motivated my journey into new fields. RIP, Fraser—your legacy now impacts science far beyond chemistry.

[5/6] Why do PAMs matter?
PAMs are a new form of matter with vast potential:
• Adaptive aerospace structures
• Soft robotics
• Protective gear
…and more. We’re just beginning to explore their vast possibilities!

[4/6] This work wouldn’t have been possible without an incredible team:
Prof. Chiara Daraio: Visionary leadership.
Sujeeka Nadarajah: Co-lead author & expert in experimental mechanics.
Prof. Liuchi Li: Numerical simulations.
Dr. Xiaoxing Xia: MicroPAMs & electrostatic actuation.

[3/6] What makes PAMs exciting?
PAMs bridge granular and crystalline systems—combining grain flexibility with lattice rigidity. Under light loads, they flow like fluids; under increased loads, they lock into rigid solids. Ideal for energy absorption, robotics, and beyond!

[2/6] What are PAMs?
Inspired by chain maille, PAMs are strategically designed and 3D printed with interlocking rings and cages, forming 3D structures with programmable transitions between fluid-like and solid-like behaviors. TLDR: think “chain maille on steroids”!

[1/6] Excited to share our latest research featured on the @science.org cover! Meet PAMs (Polycatenated Architected Materials)—a new class of 3D-architected materials that challenge traditional boundaries between solids and granular matter. Read our paper: www.science.org/doi/10.1126/...

3D polycatenated architected materials Architected materials derive their properties from the geometric arrangement of their internal structural elements. Their designs rely on continuous networks of members to control the global mechanica...

It's chain mail day in @science.org with two exciting papers! The cover showcases a systematic study of 3D-printed macroscopic motifs linked in all 3 dimensions, which manifest fascinating wide-ranging responses to shear, depending on specific morphology

Glad you like them, Daryl :)
