Thermodynamics at the nanoscale: A new approach to the investigation of unique physicochemical properties of nanomaterials
Publication date: May 2014 Source:Materials Science and Engineering: R: Reports, Volume 79 Author(s): Chun Cheng Yang , Yiu-Wing Mai An extension of the classic thermodynamics theory to nanometer scale has generated a new interdisciplinary theory – nanothermodynamics. It serves as a bridge between macroscopic and nanoscopic systems. Over the past decade, nanothermodynamics theories have developed rapidly owing to their critical role in investigating the size-dependent physicochemical properties of nanomaterials. This review examines up-to-date research results on this cutting-edge topic. The focus and emphasis are ...

Biomimetic porous scaffolds for bone tissue engineering
Publication date: June 2014 Source:Materials Science and Engineering: R: Reports, Volume 80 Author(s): Shuilin Wu , Xiangmei Liu , Kelvin W.K. Yeung , Changsheng Liu , Xianjin Yang Increased use of reconstruction procedures in orthopedics, due to trauma, tumor, deformity, degeneration and an aging population, has caused a blossom, not only in surgical advancement, but also in the development of bone implants. Traditional synthetic porous scaffolds are made of metals, polymers, ceramics or even composite biomaterials, in which the design does not consider the native structure and properties of cells and natural tis...

Structure and properties of lead-free solders bearing micro and nano particles
Publication date: August 2014 Source:Materials Science and Engineering: R: Reports, Volume 82 Author(s): Liang Zhang , K.N. Tu Composite lead-free solders, containing micro and nano particles, have been widely studied. Due to grain boundary drag or Zener drag, these particles can refrain the solder microstructure from coarsening in services, especially for Cu6Sn5, Ag3Sn intermetallic compounds and the β-Sn phases. Due to dispersion hardening or dislocation drag, the mechanical properties of the composite solder alloys were enhanced significantly. Moreover, these particles can influence the rate of interfacial reacti...

Materials engineering for surface-confined flame retardancy
Publication date: October 2014 Source:Materials Science and Engineering: R: Reports, Volume 84 Author(s): Giulio Malucelli , Federico Carosio , Jenny Alongi , Alberto Fina , Alberto Frache , Giovanni Camino Polymer materials flammability represents a major limitation to their use and hence to the development of most polymer-based advanced technologies. Environmental and safety concerns are leading to progressive phasing out of versatile and effective halogen-based fire retardants which, so far, ensured a satisfactory polymer fire hazard control. Among the intensive efforts which are being made to develop new, env...
