Emergent grain boundary phases in stressed polycrystalline thin films
Mengyuan Wang, Ruilin Yan, Xiao Han +2
The grain boundary (GB) microstructure influences and is influenced by the development of residual stresses during synthesis of polycrystalline thin films. Recent studies have show…
Microgroove convexity is critical for robust gaseous layers on hierarchically-structured superhydrophobic surfaces
Xiao Han, Jingnan Liu, Moneesh Upmanyu +1
Gaseous layers (plastrons) trapped on the surfaces of immersed hydrophobic surfaces are critical for their function. Fibrillar morphologies offer a natural pathway, yet they are li…
Solute drag forces from equilibrium interface fluctuations
Changjian Wang, Moneesh Upmanyu
The design of polycrystalline alloys hinges on a predictive understanding of the interaction between the diffusing solutes and the motion of the constituent crystalline interfaces.…
Stability and energetics of 2D surface crystals in liquid AuSi thin films and nanoscale droplets
Hailong Wang, Alireza Shahabi, Alain Karma +1
Segregation at surfaces of metal-covalent binary liquids is often non-classical and in extreme cases such as AuSi, the surface crystallizes above the melting point. In this study,…
Phase-field model of vapor-liquid-solid nanowire growth
Nan Wang, Moneesh Upmanyu, Alain Karma
We present a multi-phase-field model to describe quantitatively nanowire growth by the vapor-liquid-solid (VLS) process. The free-energy functional of this model depends on three n…
Interface-mediated thermomechanical effects during high velocity impact between monocrystalline surfaces
Zhenqi Yang, Sinan Muftu, Moneesh Upmanyu
High velocity impact between crystalline surfaces is important for a range of material phenomena, yet a fundamental understanding of the effect of surface structure, energetics and…
