Special Issue Information

Dear Colleagues,

MD modelling has become a valuable complementary tool to experimental techniques in the study of complex materials. MD simulations can now access unprecedented temporal and spatial scales, with fully atomistic simulations reaching microseconds in length on systems composed of hundreds of thousands of atoms. The refinement of force-field parameters has considerably increased the accuracy of MD simulations. Importantly, it is becoming increasingly common to carry out MD modelling studies of molecular systems prior to actual experiments and even synthesis. The accuracy of MD in conjunction with novel data processing algorithms allows the reliable prediction of physical, chemical, and spectroscopic properties of materials, thus not only assisting in the interpretation of experimental data but also influencing experimental design and strategies for developing new materials with desired functionalities. With further advances in computer power, the accessibility of MD software, the parallelisation of codes, and emerging AI algorithms, the impact of MD modelling on materials science is anticipated to grow even stronger in the near future.

This Special Issue aims to highlight recent achievements in the development of MD simulation methods and models as well as their applications to various systems and phenomena in materials science. It is my pleasure to invite you to submit your works in the form of preliminary communications, original research articles or reviews.

Potential applications include, but are not limited to, the following:

  • Liquid crystals;
  • Lyotropic and chromonic systems;
  • Lipid-based systems;
  • Polymer systems;
  • Nanomaterials;
  • Solids;
  • Thin films;
  • Metal organic frameworks;
  • Bio-inspired materials.

Despite the fact that engineered surface enabling remarkable phase change heat transfer have elicited increasing attention due to their ubiquitous applications in thermal management, the underlying mechanisms of intrinsic rough structures as well as the surface wettability on bubble dynamics remain to be explored. Therefore, a modified molecular dynamics simulation of nanoscale boiling was conducted in the present work to investigate bubble nucleation on rough nanostructured substrates with different liquid–solid interactions. Specifically, the initial stage of nucleate boiling was mainly investigated and the bubble dynamic behaviors were quantitively studied under different energy coefficients. Results shows that as the contact angle decreases, the nucleation rate increases, because liquid obtains more thermal energy there compared with that on less wetting surfaces. The rough profiles of the substrate can provide nanogrooves, which can enhance initial nucleate embryos, thereby improving thermal energy transfer efficiency. Moreover, atomic energies are calculated and adopted to explain how bubble nuclei are formed on various wetting substrates. The simulation results are expected to provide guidance towards surface design in state–of–the art thermal management systems, such as the surface wettability and the nanoscale surface patterns.
