These properties behave differently at the nano scale. Low-dimensional nanomaterials have various unusual size dependent transport properties. In this review, we summarize the theoretical and experimental reports on the size effect on melting temperature, heat capacity, reaction enthalpy, and surface energy of the materials at nano scale because nanomaterials possess a significant change in large specific surface area and surface effect than the bulk materials. According to the theoretical analysis of size dependent thermodynamic properties, such as melting temperature, cohesive energy, thermal conductivity and specific heat capacity of metallic nanoparticles and ultra-thin layers varies linearly with the reciprocal of the critical dimension. The result of this scaling relation on the material properties can affect the self-sustained reaction behavior in reactive materials. Resultant, powder compacts show lower reaction propagation velocities than bilayer system, if the particle size of the reactants and the void density is decreased an increase of the reaction propagation velocity due to an enhanced heat transfer in reactive materials can be achieved. Standard theories describing the properties of reactive material systems do not include size effects. reactive multilayers reactive particles self-sustained reaction propagation velocity phase transformation surface energy melting temperature article Vauth, Maximilian Author aut Pezoldt, Jörg Author aut Technische Universität Ilmenau Fakultät für Elektrotechnik und Informationstechnik host institution his 10:4:56 Technische Universität Ilmenau, Universitätsbibliothek Inorganics 2304-6740 dbt_mods_00049452 1.2013 - https://www.db-thueringen.de/receive/dbt_mods_00052549 object in context https://www.db-thueringen.de/servlets/MCRFileNodeServlet/dbt_derivate_00056644/inorganics-10-00056.pdf raw object https://www.db-thueringen.de/rsc/thumbnail/dbt_mods_00052549.png preview http://uri.gbv.de/document/gvk:ppn:1802593365 uri
