Background: Managing the heat generated in microprocessors and other similar heat-generating devices requires the design and construction of superconductors with high reliability. For this purpose, heat pipes (HPs) are a very good option. Nano-grooved micro flat plate heat pipes (FPHPs), which are in the group of vapor chambers (VCs), have received attention due to their suitable structure.

- This study explored how the size of BaTiO ceramics affects their piezoelectric properties using molecular dynamics simulations, confirming thermal and potential energy equilibrium at 300 K within 10 ns.
- As the ceramic size increased, both the mean square displacement and diffusion coefficients decreased, indicating a more uniform microstructure with reduced ion mobility due to fewer defects.
- The findings revealed that larger BaTiO samples showed enhanced polarization values, while the increased stress from better domain alignment limited the mobility of the domain walls, emphasizing the importance of size and microstructure in optimizing ferroelectric materials for electronic applications.
Methods: This research studied the effect of initial temperature (300-400K), and atomic percentage of toluene catalyst (1-10%) on the atomic and thermal performance of air/methane catalytic combustion. The present study was performed using molecular dynamics (MD) simulation.
Context: The results demonstrate that by increasing the initial temperature from 300 to 400 K, the maximum velocity and temperature increased from 0.
Today, with the advancement of science in nanotechnology, it is possible to remove dust nanostructures from the air breathed by humans or other fluids. In the present study, the separation of SiO molecules from HO vapor is studied using molecular dynamics (MD) simulation. This research studied the effect of initial temperature, nanopore geometry, and initial pressure on the separation of SiO molecules.
