Stochastic Surface Growth
Growth phenomena constitute an important field in nonequilibrium statistical mechanics. Kardar, Parisi, and Zhang (KPZ) in 1986 proposed a continuum theory for local stochastic growth predicting scale invariance with universal exponents and limiting distributions. For a special, exactly solvable …

Kinetics of surface growth and coupled diffusion in a continuum framework
Surface growth by association or dissociation of material on the boundary of a body is ubiquitous in both natural and engineering systems. It is the fundamental mechanism by which biological materials grow, starting from the level of a single cell, and is increasingly applied in engineering …

Mechanics of Seashell Growth: Examining the relationship between incompatibility, shape, and internal stress
Seashells are a fascinating example of surface growth in nature. As they develop, both their macroscopic form and their internal microstructure evolve, with the latter transitioning between different layer sizes and orientations during the shell's growth process. Several studies have examined the …

Experimental and Numerical Studies on the Soot Formation of Liquid Fuel Relevant Compounds
… the relative importance of soot inception and surface growth affected by n-propylbenzene addition is different along the flame wing and centerline, with the aromatic fuel chemistry effect being stronger along the centerline. The third study extends the investigation on the same issue using a …

Molecular weight growth pathways in fuel-rich combustion
… be placed under the heading of molecular weight growth. Evidence exists for the carcinogenicity of many P AH molecules. Soot is used as a component of dyes and as an additive to rubbers as well as being an undesirable atmospheric pollutant. Both are emitted from many typical combustion processes …

The effects of molecular structures and reactant temperatures on soot formation in a coflow laminar flame
… temperature promotes soot aggregation and soot surface growth. It also yields curved nanostructures that decelerate soot surface growth. In addition, the modeling study shows the promotion of soot formation is likely due to early fuel pyrolysis that promotes PAH formation. The increase in PAH …

Diffusion and growth of steps and islands on surfaces
Surface science aims at the control of surface structures even on atomistic scales. Growth of metal and semiconductor crystal surfaces requires accurate growth techniques, among which Molecular Beam Epitaxy (MBE) has a special status since it can be very efficiently used to produce growth in well …

Flow Induced Crystallization of Polyethylene Fibers From Solution
This study deals mainly with investigating the growth sequence of a polyethylene fiber in the Poiseuille flow geometry. Features of an earlier study using the surface growth method to produce polyethylene fibers in Couette geometry are also included in the discussion. Fiber growth is initiated from …

Relaxation phenomena during non-equilibrium growth
The surface width, a global quantity that depends on time, is used to characterize the temporal evolution of growing surfaces. One of the most successful concepts for describing the property of the surface width is the famous Family-Vicsek scaling relation. We discuss an extended scaling relation …
