Curved carbon nanotubes (CCNT) can exhibit both in-plane and out-of-plane vibrations, and their curvature can give rise to additional vibrational modes. The vibrational modes of CCNT can be influenced by various factors, including diameter …

The paper is concerned with the study of a chemical reaction between diffusing and solid constituents. The reaction is localized at a propagating reaction front and is accompanied by a transformation strain, which generates stresses affecting the …
