JMMP focuses on theoretical developments, experimental innovations, and computational and simulation methods in the fields of micromechanics and molecular physics, and the discovery of nanoscale and nanostructured materials, composite materials, and novel advanced materials, with emphasis on the mechanics and physics of microstructures, characterization and modeling, material design, processing and manufacturing, and the interrelation and correlation between the micro-/nanostructures of materials and their macroscale functions.
JMMP publishes research papers, review articles, research letters, and commentary perspective articles. It covers a broad range of topics in the micromechanics and molecular physics of materials. The materials of interest are as follows: nanoscale materials including nanoparticles, nanocrystals, nanotubes, nanowires, nanofibers, nanorods, and nanoporous materials; soft matter materials including polymeric and biological materials, colloids, surfactants, membranes, self-assembled molecules and nanoparticles, and hybrid materials or materials with hierarchical structures; materials with surface and/or interface microstructures; and inorganic/organic composites, ceramics, metals, and alloys. One of the emphases of the journal is to provide rapid communication on current research developments in micromechanics concerning micro-defects such as dislocations, disclinations, grain boundaries, and cracks in materials. JMMP also highlights the modeling and simulation of microscale and nanoscale materials using advanced computational techniques in molecular physics such as first-principles calculations, molecular dynamics simulations, Monte Carlo methods, and various multiscale homogenization theories and techniques.
