Super-elastic collisions of thermal activated nanoclusters
نویسندگان
چکیده
Impact processes of nanoclusters subject to thermal fluctuations are investigated, theoretically. In the former half of the paper, we discuss the basis of quasi-static theory. In the latter part, we carry out the molecular dynamics simulation of collisions between two identical nanoclusters, and report some statistical properties of impacts of nanoclusters.

Super-elastic collisions in a thermally activated system
Impact phenomena of small clusters subject to thermal fluctuations are numerically investigated. From the molecular dynamics simulation for colliding two identical clusters, it is found that the restitution coefficient for head-on collisions can exceed unity when the colliding speed is smaller than the thermal velocity of one “atom” of the clusters. The averaged behavior can be understood by th...
متن کاملTurn on the super-elastic collision nature of coronal mass ejections through low approaching speed
It has been proved from the observations and numerical simulations that the collision between solar coronal mass ejections (CMEs), the largest plasmoids in the heliosphere, could be super-elastic. This finding suggests that the CMEs' magnetic energy and thermal energy could be converted into kinetic energy through a more efficient way. However CME collisions are not always super-elastic, which ...
متن کاملMorphological investigation of Graphene Oxide/ Polyacrylamide super-elastic nanocomposite by a solution polymerization process with enhanced rheological property and thermal conductivity
A series of Graphene Oxide/ Polyacrylamide (GO/PAM) super-elastic nanocomposites with different amounts of Graphene Oxide Nanosheets (GONSs) (0.5, 1, 1.5, and 2 wt. %) were synthesized using an in-situ polymerization in an aqueous medium in this paper. To this end, we proposed a method for obtaining super-elastic nanocomposites with a high dispersion of GONSs in the PAM chains as well as in a r...
متن کاملOxygen reduction reaction on Pt/C at the presence of super paramagnetic of Fe3O4 nanoparticles for PEMFCs
In this paper the role of super paramagnetic iron oxide nanoparticles (SPI) on Platinum nanoclusters on activated carbon (Pt/C) for electrocatalytic oxygen reduction reaction was considered. Four composites of Pt/C and super paramagnetic iron oxide nanoparticles were prepared with the same total composites weight and different loading of Pt/C (1.2, 0.6, 0.4 and 0.3 mg ). The composite attached ...
متن کاملNonlinear Thermo-Mechanical Behaviour Analysis of Activated Composites With Shape Memory Alloy Fibres
General thermo-mechanical behavior of composites reinforced by shape memory alloy fibers is predicted using a three-dimensional analytical micromechanical method to consider the effect of fibers activation. Composite due to the micromechanical method can be exposed to general normal and shear mechanical and thermal loading which cause to activate the shape memory alloy fibers within polymeric m...
