Thermal Grooving by Surface Diffusion: a Review of Classical Thermo-Kinetics Approach
Hittite Journal of Science and Engineering, 2017 I n polycrystalline materials wherever a grain boundary intersects a free surface and whenever the topographic variation associated with the atomic motion is favored by total free energy dissipation, the material surface grooves.

Anisotropic diffusion in continuum relaxation of stepped crystal surfaces [PDF]
, 2007 We study the continuum limit in 2+1 dimensions of nanoscale anisotropic diffusion processes on crystal surfaces relaxing to become flat below roughening.

The robust finite-volume schemes for modeling nonclassical surface reactions
Nonlinear Analysis, 2018 A coupled system of nonlinear parabolic PDEs arising in modeling of surface reactions with piecewise continuous kinetic data is studied. The nonclassic conjugation conditions are used at the surface of the discontinuity of the kinetic data.

Multiscale Apparent Permeability Model of Shale Nanopores Based on Fractal Theory
Energies, 2019 Based on fractal geometry theory, the Hagen−Poiseuille law, and the Langmuir adsorption law, this paper established a mathematical model of gas flow in nano-pores of shale, and deduced a new shale apparent permeability model.

Area confined position control of molecular aggregates
New Journal of Physics, 2016 We report an experimental approach to control the position of molecular aggregates on surfaces by vacuum deposition. The control is accomplished by regulating the molecular density on the surface in a confined area.

Mechanism of Spontaneous Surface Modifications on Polycrystalline Cu Due to Electric Fields
Micromachines, 2021 We present a credible mechanism of spontaneous field emitter formation in high electric field applications, such as Compact Linear Collider in CERN (The European Organization for Nuclear Research).

Fluctuations and scaling in models for particle aggregation
, 2005 We consider two sequential models of deposition and aggregation for particles. The first model (No Diffusion) simulates surface diffusion through a deterministic capture area, while the second (Sequential Diffusion) allows the atoms to diffuse up to \ell

Sediment deposition model of grading electrode in water cooling circuit of HVDC converter valve
The Journal of Engineering, 2019 The converter valve is one of the core equipment in high-voltage direct current (HVDC) system, and the cooling system is often used for heat dissipation.

Lifespan theorem for constrained surface diffusion flows [PDF]
, 2011 We consider closed immersed hypersurfaces in $\R^{3}$ and $\R^4$ evolving by a class of constrained surface diffusion flows. Our result, similar to earlier results for the Willmore flow, gives both a positive lower bound on the time for which a smooth ...
