Mechanical Properties of Diamond Schwarzites: From Molecular Dynamics Simulations to 3D Printing
Levi C. Felix, Vladimir Gaál, Cristiano F. Woellner +2
Schwarzites are porous crystalline structures with Gaussian negative curvature. In this work, we investigated the mechanical behavior and energy absorption properties of two carbon…
Mechanical Properties of a Diamond Schwarzite: From Atomistic Models to 3D-Printed Structures
Levi C. Felix, Vladimir Gaal, Cristiano F. Woellner +2
Triply Periodic Minimal Surfaces (TPMS) possess locally minimized surface area under the constraint of periodic boundary conditions. Different families of surfaces were obtained wi…
New zero Poisson's ratio models
Vladimir Gaal, Varlei Rodrigues, Socrates O. Dantas +2
Most materials exhibit positive Poisson's ratio (PR) values but special structures can also present negative and, even rarer, zero (or close to zero) PR. Null PR structures have re…
Observation of the Smallest Metal Nanotube with Square-cross-section
Maureen Lagos, Fernando Sato, Jeferson Bettini +3
Understanding the mechanical properties of nanoscale systems requires a range of measurement techniques and theoretical approaches to gather the relevant physical and chemical info…
Is Small Perfect? Size Limit to Defect Formation in Pyramidal Pt Nanocontacts
Varlei Rodrigues, Fernando Sato, Douglas S. Galvao +1
We report high resolution transmission electron microscopy and ab initio calculation results for the defect formation in Pt nanocontacts (NCs). Our results show that there is a siz…
Evidence of spontaneous spin polarized transport in magnetic nanowires
Varlei Rodrigues, Jefferson Bettini, Paulo C. Silva +1
The exploitation of the spin in charge-based systems is opening revolutionary opportunities for device architecture. Surprisingly, room temperature electrical transport through mag…
