Hello, I'm Samiul Hossain Sajal

Here's what I explored and achieved:

• Simulated Nanoparticle Formation: Conducted Molecular Dynamics (MD) simulations using the ReaxFF reactive force field in LAMMPS to analyze the phase transition and behavior of aluminum (Al) nanoparticles.
• Investigated Temperature Dependence: Examined the impact of varying temperature decrease rates (0.1, 0.3, 0.5, 1.0, and 10.0 K/ps) on ANP formation from an initial plasma state of 5000 K down to 300 K.
• Analyzed Nanoparticle Characteristics:
  • Quantified nanoparticle formation rates and growth of the biggest nanoparticles.
  • Performed neighbor analysis to understand particle attachment and stability within clusters.
  • Determined the size and structural properties of ANPs using cluster analysis and Polyhedral Template Matching (PTM).
  • Described physical properties (volume, density, energy) to validate simulation stability.
• Compared Simulation Outcomes: Provided a comparative analysis of nanoparticle count, size (by particle number, mesh surface, and diameter), and size distribution across different cooling rates.
• Key Finding: Demonstrated that the rate of nanoparticle formation and their ultimate size are directly influenced by the pace of temperature drop, suggesting a powerful mechanism for controlling PLAL synthesis efficiency.
