The Temperature-Sensitive Anisotropic Negative Poisson’s Ratio of Carbon Honeycomb [PDF]

open access: yesNanomaterials, 2019
We report that carbon honeycomb, a new three-dimension carbon allotrope, exhibits large negative Poisson’s ratio, as large as −0.32, in tensile revealed via molecular dynamics simulations.

A Tubular Biomaterial Construct Exhibiting a Negative Poisson's Ratio. [PDF]

open access: yesPLoS ONE, 2016
Developing functional small-diameter vascular grafts is an important objective in tissue engineering research. In this study, we address the problem of compliance mismatch by designing and developing a 3D tubular construct that has a negative Poisson's ...

A seamless auxetic substrate with a negative Poisson’s ratio of −1 [PDF]

open access: yesNature Communications
Auxetic metamaterials are a unique class of materials or structures with a negative Poisson’s ratio and a wide array of functionalities. However, their inherent porosity presents challenges in practical applications.

Tunable Negative Poisson’s Ratio in Van der Waals Superlattice

open access: yesResearch, 2021
Negative Poisson’s ratio (NPR) materials are functional and mechanical metamaterials that shrink (expand) longitudinally after being compressed (stretched) laterally. By using first-principles calculations, we found that Poisson’s ratio can be tuned from
