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

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

Metal [100] Nanowires with Negative Poisson's Ratio. [PDF]
Sci Rep, 2016 AbstractWhen materials are under stretching, occurrence of lateral contraction of materials is commonly observed. This is because Poisson’s ratio, the quantity describes the relationship between a lateral strain and applied strain, is positive for nearly all materials.

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

NEGATIVE POISSON’S RATIO AND PERCOLATING STRUCTURES
TASK Quarterly, 2001 Elastic properties of non-uniform, two-component systems are studied in frames of a model of percolation on a simple cubic lattice. It is shown that as the ratio of the bulk moduli of the components tends to zero, ϰ = Ks/Kh → 0 (where s, h denote the ...
