Can Neural Networks Learn Nanoscale Friction?
Mahboubeh Shabani, Andrea Silva, Franco Pellegrini +6
Current nanofriction experiments on crystals, both tip-on-surface and surface-on-surface, provide force traces as their sole output, typically exhibiting atomic size stick-slip osc…
The twisting dynamics of large lattice mismatch van der Waals heterostructures
Mengzhou Liao, Andrea Silva, Luojun Du +7
Van der Waals (vdW) homo-/hetero-structures are ideal systems for studying interfacial tribological properties such as structural superlubricity. Previous studies concentrated on t…
Emerging chirality and moiré dynamics in twisted layered material heterostructures
Andrea Silva, Xiang Gao, Melisa M. Gianetti +5
Moiré superstructures arising at twisted 2D interfaces have recently attracted the attention of the scientific community due to exotic quantum states and unique mechanical and trib…
Rheological softening of metal nanocontacts sheared under oscillatory strains
Ali Khosravi, Jin Wang, Andrea Silva +2
The way metal interfaces evolve during frictional sliding, and how that evolution can be externally influenced under external drivers are important questions, hard to investigate e…
Solid lubrication by wet-transferred solution-processed graphene flakes: dissipation mechanisms and superlubricity in mesoscale contacts
Renato Buzio, Andrea Gerbi, Cristina Bernini +3
Solution-processed few-layers graphene flakes, dispensed to rotating and sliding contacts via liquid dispersions, are gaining increasing attention as friction modifiers to achieve…
Anisotropic Rheology and Friction of Suspended Graphene
Andrea Mescola, Andrea Silva, Ali Khosravi +4
Graphene is a powerful membrane prototype for both applications and fundamental research. Rheological phenomena including indentation, twisting, and wrinkling in deposited and susp…
Bending Stiffness Collapse, Buckling, Topological Bands of Freestanding Twisted Bilayer Graphene
Jin Wang, Ali Khosravi, Andrea Silva +3
The freestanding twisted bilayer graphene (TBG) is unstable, below a critical twist angle θ_c~3.7 degrees, against a moire (2 \times 1) buckling distortion at T=0. Realistic simula…
Design guidelines for two-dimensional transition metal dichalcogenide alloys
Andrea Silva, Jiangming Cao, Tomas Polcar +1
Two-dimensional (2D) materials and Transition Metal Dichalcogenides (TMD) in particular are at the forefront of nanotechnology. To tailor properties for engineering applications, a…
Frictionless nanohighways on crystalline surfaces
Emanuele Panizon, Andrea Silva, Xin Cao +5
The understanding of friction at nano-scales, ruled by the regular arrangement of atoms, is surprisingly incomplete. Here we provide a unified understanding by studying the interlo…
Pettifor Maps of Complex Ternary Two-dimensional Transition Metal Sulphides
Andrea Silva, Jiangming Cao, Tomas Polcar +1
Alloying is an established strategy to tune the properties of bulk compounds for desired applications. With the advent of nanotechnology, the same strategy can be applied to 2D mat…
Critical Peeling of Tethered Nanoribbons
Andrea Silva, Erio Tosatti, Andrea Vanossi
The peeling of an immobile adsorbed membrane is a well known problem in engineering and macroscopic tribology. In the classic setup, picking up at one extreme and pulling off resul…
Moiré-pattern evolution couples rotational and translational friction at crystalline interfaces
Xin Cao, Andrea Silva, Emanuele Panizon +4
The sliding motion of objects is typically governed by their friction with the underlying surface. Compared to translational friction, however, rotational friction has received muc…
Multi-scale model predicting friction of crystalline materials
Paola C. Torche, Andrea Silva, Denis Kramer +2
We present a multi-scale computational framework suitable for designing solid lubricant interfaces fully in silico. The approach is based on stochastic thermodynamics founded on th…
Phase behaviour of (Ti:Mo)S binary alloys arising from electron-lattice coupling
Andrea Silva, Tomas Polcar, Denis Kramer
While 2D materials attract considerable interests for their exotic electronic and mechanical properties, their phase behaviour is still largely not understood. This work focuses on…
Exploring the stability of twisted van der Waals heterostructures
Andrea Silva, Victor E. P. Claerbout, Tomas Polcar +2
Recent research showed that the rotational degree of freedom in stacking 2D materials yields great changes in the electronic properties. Here we focus on an often overlooked questi…
Experimental observation of the Aubry transition in two-dimensional colloidal monolayers
T. Brazda, A. Silva, N. Manini +4
The possibility to achieve entirely frictionless, i.e. superlubric, sliding between solids, holds enormous potential for the operation of mechanical devices. At small length scales…
