Despite the difficulties in synthesizing such materials, interest in this field has blossomed with recent experimental and theoretical results. Such progress has led to the development of superhard metal borides, ultraincompressible nitrides, and strong carbides. Our previous parameters of

  • Thermal Boundary Conductance: A Materials Science Perspective
    Annu. Rev. Mater. Res. (IF 16.816) Pub Date : 2016-07-01
    Christian Monachon, Ludger Weber, Chris Dames

    The thermal boundary conductance (TBC) of materials pairs in atomically intimate contact is reviewed as a practical guide for materials scientists. First, analytical and computational models of TBC are reviewed. Five measurement methods are then compared in terms of their sensitivity to TBC: the 3ω method, frequency- and time-domain thermoreflectance, the cut-bar method, and a composite effective thermal

    Flory Wong, Krishna Kanti Dey, Ayusman Sen

    Synthetic active systems capable of autonomous motion or driving fluid flow are of great current interest owing to their potential applications in nanomachinery, cargo capture and delivery, reversible assemblies, and chemical/biochemical sensing. Designing self-powered micro/nanomotors and understanding their propulsion mechanisms and ensemble behavior are now areas of great interest in low-Reynolds-number

  • Recent Advances in Superhard Materials
    Annu. Rev. Mater. Res. (IF 16.816) Pub Date : 2016-07-01
    Zhisheng Zhao, Bo Xu, Yongjun Tian

    In superhard materials research, two topics are of central focus. One is to understand hardness microscopically and to establish hardness models with atomic parameters, which can be used to guide the design or prediction of novel superhard crystals. The other is to synthesize superhard materials with enhanced comprehensive performance (i.e., hardness, fracture toughness, and thermal stability), with

  • Raman Studies of Carbon Nanostructures
    Annu. Rev. Mater. Res. (IF 16.816) Pub Date : 2016-07-01
    Ado Jorio, Antonio G. Souza Filho

    This article reviews recent advances on the use of Raman spectroscopy to study and characterize carbon nanostructures. It starts with a brief survey of Raman spectroscopy of graphene and carbon nanotubes, followed by recent developments in the field. Various novel topics, including Stokes–anti-Stokes correlation, tip-enhanced Raman spectroscopy in two dimensions, phonon coherence, and high-pressure

  • Polymer-Derived Ceramic Fibers
    Annu. Rev. Mater. Res. (IF 16.816) Pub Date : 2016-07-01
    Hiroshi Ichikawa

    SiC-based ceramic fibers are derived from polycarbosilane or polymetallocarbosilane precursors and are classified into three groups according to their chemical composition, oxygen content, and C/Si atomic ratio. The first-generation fibers are Si-C-O (Nicalon) fibers and Si-Ti-C-O (Tyranno Lox M) fibers. Both fibers contain more than 10-wt% oxygen owing to oxidation during curing and lead to degradation

  • Physics of Ultrathin Films and Heterostructures of Rare-Earth Nickelates
    Annu. Rev. Mater. Res. (IF 16.816) Pub Date : 2016-07-01
    S. Middey, J. Chakhalian, P. Mahadevan, J.W. Freeland, A.J. Millis, D.D. Sarma

    The electronic structure of transition metal oxides featuring correlated electrons can be rationalized within the Zaanen-Sawatzky-Allen framework. Following a brief description of the present paradigms of electronic behavior, we focus on the physics of rare-earth nickelates as an archetype of complexity emerging within the charge transfer regime. The intriguing prospect of realizing the physics of

  • Material Evaluation by Infrared Thermography
    Annu. Rev. Mater. Res. (IF 16.816) Pub Date : 2016-07-01
    Stephen D. Holland, Ricky S. Reusser

    Infrared thermography uses the temperature-imaging capability of modern thermal cameras to characterize materials and detect flaws. An energy source—whether a pulse of light from a laser or flash lamp, an induction coil, or some other source—induces heat flow in a material, and the resulting temperature patterns are imaged with the thermal camera. In flash thermography, the most widely used form of

  • Dealloying and Dealloyed Materials
    Annu. Rev. Mater. Res. (IF 16.816) Pub Date : 2016-07-01
    Ian McCue, Ellen Benn, Bernard Gaskey, Jonah Erlebacher

    A successful working model for nanoporosity evolution during dealloying was introduced 15 years ago. Since that time, the field has rapidly expanded, with research groups from across the world studying dealloying and dealloyed materials. Dealloying has grown into a rich field, with some groups focusing on fundamentals and mechanisms of dealloying, other groups creating new porous metals and alloys

    Samrat Ghosh, Vakayil K. Praveen, Ayyappanpillai Ajayaghosh

    π-Gels are a promising class of functional soft materials formed out of short π-conjugated molecules. By utilizing the chemistry of noncovalent interactions, researchers have created a wide range of π-gels that are composed of supramolecular polymers. During the last two decades, supramolecular gel chemistry has been pursued with the hope of developing new materials for applications in, for example

    Mikhail Osanov, James K. Guest

    Advanced manufacturing processes provide a tremendous opportunity to fabricate materials with precisely defined architectures. To fully leverage these capabilities, however, materials architectures must be optimally designed according to the target application, base material used, and specifics of the fabrication process. Computational topology optimization offers a systematic, mathematically driven
