The Journal of Materials Science is now firmly established as the leading source of primary communication for scientists investigating the structure and properties of all engineering materials. Materials include metals, ceramics, glasses, polymers, energy materials, electrical materials, composite materials, fibers, nanostructured materials, nanocomposites, and biological and biomedical materials. The focus of the Journal of Materials Science is on the science behind the structure-property relationships in materials. This includes research on the synthesis and properties of new materials, but also includes research on new scientific results related to the important properties of existing materials. Research solely focused on the applications of materials, engineering analysis of the performance of materials, or systematic studies on the synthesis or properties of materials will not be given consideration. Manuscripts on these topics are aligned with the Aims and Scope of our sister journal the Journal of Materials Science: Materials in Engineering. Categories with collections content are listed below in alphabetical order: Ceramics: oxides, nitrides and chalcogenides, geopolymers, inorganic membranes, porous materials such as zeolites and mesoporous inorganics, and electronic ceramics. Chemical routes to materials: synthesis of nanomaterials, catalysts and sensors, preparation of materials including 2D materials. Composites & nanocomposites: reinforced polymers and biopolymers including nanoparticle-reinforced materials, ceramic-matrix composites, metal-matrix composites and laminates. Computation & theory: atomistic simulation, machine learning and AI, mathematical modelling and big data approaches to materials. Electronic materials: all semiconductors and related materials including graphene, capacitors, display materials, and piezoelectric materials. Energy materials: batteries, supercapacitors, fuel cells, photovoltaics, chemical energy storage and other materials for energy conversion. Materials for life sciences: biomechanics, cellular interactions with biomaterials (except for in vivo work), biocompatibility, bioelectronics, controlled release, materials for photodynamic and photothermal treatments, manufacturing, biomimetic approaches, and bioreactors. Metals & corrosion: casting, solidification, additive manufacturing, protective coatings, metallic glasses, high-entropy metals, and superalloys, Laves phases, dislocations and interfaces. Polymers & biopolymers: includes cellulose and other natural polymers and polymer membranes. The Journal of Materials Science publishes reviews and full-length papers recording original research results on, or techniques for, studying the relationship between structure, properties, and uses of materials. Please see the Instructions for Authors for details about the format for full-length papers and review articles.
