Experimental and Theoretical Aspects of the Fragmentation of Carbon's Single and Multi-Walled Nanotubes
Sumera Javeed, Shoaib Ahmad
Energetic ion irradiation is an effective method for studying how single and multi-shelled carbon nanotubes break apart. The energy from ions is dissipated through both linear and…
Dynamic emergence of fragmenting, exploding cages of irradiated single-walled carbon nanotubes and C60
Shoaib Ahmad
Experimental results from irradiated-carbon nanostructures can be partially explained by selective applications of classical damage theories and ad-hoc thermal models by treating t…
Multi scaling of Fractal Dimension and Relative Entropy as Diagnostic Tools for Irradiated Carbon Nano-tubes
Shoaib Ahmad, Sumera Javeed
Linear and nonlinear dissipative structures emerge in the irradiated single and multi walled carbon nano-tubes in the form of collision cascades and thermal spikes. These are diagn…
Information-theoretic model of self-organizing fullerenes and the emergence of C60
Shoaib Ahmad
An information-theoretic model describes the dissipative dynamical systems composed of ensembles of fragmenting, self-organizing fullerenes. The probabilities derived from the vari…
Information generating, sharing and manipulating Source-Reservoir-Sink model of self-organizing dissipative structures
Shoaib Ahmad
Information-theoretic description of the signal transmitter, the channel and receiver is extended to the network of self-organizing dissipative structures consisting of a source, a…
Space-filling, multi-fractal, localized thermal spikes in silicon, germanium and zinc oxide
Shoaib Ahmad, Muhammad Sabtain Abbas, Muhammad Yousuf +3
The mechanism responsible for the emission of clusters from heavy ion irradiated solids is proposed to be thermal spikes. Collision cascade-based theories describe atomic sputterin…
An information theoretic model for the linear and nonlinear dissipative structures in irradiated single-walled carbon nanotubes
Afshan Ashraf, Sumera Javeed, Sumaira Zeeshan +2
Experiments with irradiated single-walled carbon nanotubes are shown to generate a set of probability distribution functions and to derive a set of information theoretic entropy-ba…
Carbon cluster diagnostics-II: ExB velocity filter for large carbon clusters
Shoaib Ahmad, B. Ahmad, A. Qayyum +1
An ExB velocity filter is described that has been used for the detection and diagnostics of large carbon clusters Cm (where m is up to ten thousand). The velocity and momentum anal…
