Instability driven fragmentation of nanoscale fractal islands.
نویسندگان
چکیده
Formation and evolution of fragmentation instabilities in fractal islands, obtained by deposition of silver clusters on graphite, are studied. The fragmentation dynamics and subsequent relaxation to the equilibrium shapes are controlled by the deposition conditions and cluster composition. Sharing common features with other materials' breakup phenomena, the fragmentation instability is governed by the length-to-width ratio of the fractal arms.

Fractal growth of platinum electrodeposits revealed by in situ electron microscopy.
Fractals are commonly observed in nature and elucidating the mechanisms of fractal-related growth is a compelling issue for both fundamental science and technology. Here we report an in situ electron microscopy study of dynamic fractal growth of platinum during electrodeposition in a miniaturized electrochemical cell at varying growth conditions. Highly dendritic growth - either dense branching...
متن کاملUltralong gold nanoparticle/block copolymer hybrid cylindrical micelles: a strategy combining surface templated self-assembly and Rayleigh instability.
Ultralong cylindrical micelles impregnated with gold nanoparticles were fabricated via the convergence of a surface-templated self-assembly method and the fragmentation of gold nanowires driven by Rayleigh instability. This approach could be proposed as an unconventional method for the fabrication of hybrid nanomaterials.
متن کاملStarburst-Driven Galactic Winds: Filament Formation and Emission Processes
We have performed a series of three-dimensional simulations of the interaction of a supersonic wind with a non-spherical radiative cloud. These simulations are motivated by our recent three-dimensional model of a starburst-driven galactic wind interacting with an inhomogeneous disk, which show that an optically emitting filament can be formed by the break-up and acceleration of a cloud into a s...
متن کاملEvaluating the performance of concentration-number (C-N) fractal model for separation of soil horizon regarding vertical distribution and 3D models
This study aims to evaluate the efficiency of the concentration-number (C-N) fractal model for discrimination of soil horizon regarding the depth distribution profile. In this regard, soil parameters such as pH, organic carbon content, calcareous mineral content, electrical conductivity and available phosphorus of Ziarat forestland in Golestan Province, north of Iran, has been investigated. The...
متن کاملMechanism of Structure-Driven Nonlinear Instability of Double Tearing Mode in Reversed Magnetic Shear Plasmas
The trigger for the nonlinear destabilization of the double tearing mode (DTM), referred to as a structuredriven instability leading to explosive growth and subsequent collapse, is investigated. We use the reduced MHD equations that solve the evolution of perturbations from an equilibrium deformed by two-dimensional magnetic islands during the slow evolution of the quasi-steady nonlinear regime...
