      Wind, a major source of environmental noise, forces invertebrates that communicate with plant-borne vibrations to adjust their signaling when communicating in windy conditions. However, the strategies that animals use to ...
    • Understanding the stability of Hollow nanoparticles with polycrystalline shellss 
      Valencia, Felipe; Ramírez González, Max; Varas, Alejandro; Rogan Castillo, José Antonio (American Chemical Society, 2020)
      The existence of polycrystalline shells has been widely reported in the synthesis of hollow nanoparticles; however, the exact role displayed by the grain boundaries on the stability has been scarcely studied. By including ...
    • Magnon valley Hall effect in CrI3-based van der Waals heterostructures 
      Hidalgo Sacoto, R.; González, R. I.; Vogel, E. E.; Allende, S.; Mella Riquelme, José; Cárdenas Valencia, Carlos; Troncoso, Robert E.; Muñoz Sáez, Francisco (American Physical Society, 2020)
