Paragraph starter

The stability of novel materials, such as few-layer black phosphorus, can be significantly enhanced through careful selection of processing solvents. Research by Hanlon et al. (2015) demonstrated that solvents like N-cyclohexyl-2-pyrrolidone (CHP) create protective solvation shells around black phosphorus nanosheets, limiting degradation to the material's edges and enabling its use in applications beyond electronics. This highlights the critical role of solvent-material interactions in achieving desired performance and longevity in advanced materials.
