Application

  • Carbon Dioxide Reduction to Methylamines under Metal‐Free Conditions: Reports the use of metal-free catalysts for the methylation of amines with CO2, contributing to greener chemical processes and enhancing the synthesis of methylamines (Blondiaux et al., 2014).
  • Methylamine‐Gas‐Induced Defect‐Healing Behavior of CH3NH3PbI3 Thin Films for Perovskite Solar Cells: Exploration of room-temperature, ultrafast methylamine-induced defect-healing that enhances the electronic properties and efficiency of perovskite solar cells (Zhou et al., 2015).
  • Thermally induced recrystallization of MAPbI3 perovskite under methylamine atmosphere: Describes a method for fabricating perovskite with large uniform crystalline grains using a methylamine atmosphere, improving the stability and efficiency of the material (Jacobs and Zang, 2016).
