In this work, the specific heat, sound velocity and phonon relaxation time, three key components of heat conductivity for the 1D nonlinear lattices are calculated via numerical simulations with applied external pressure. The results show that the dominant contribution for the change of heat conduction adjusted by the pressure comes from the phonon relaxation time.

This study shows that phosphorene sensors are more effective at detecting certain chemicals than other comparable materials like graphene and MoS<sub>2</sub>. After determining the optimal locations for these molecules to bind to phosphorene, discovered that the molecule-to-phosphorene charge transfer is essential for phosphorene's high adsorption capacity. Using a particular method, computed the relationship between the drain current and gate voltage for various gas concentrations on phosphorene. The transport properties show significant changes in the armchair direction of phosphorene, which aligns with its unique electronic structure, indicating major changes in current–voltage behavior when gas molecules are added. High sensitivity to gas adsorption of phosphorene of phosphorene, makes it an excellent gas sensor and shows its potential for use in electronic devices.
