Sum-frequency generation vibrational spectroscopy (SFG-VS) can provide detailed information and understanding of the molecular composition, interactions, and orientational and conformational structure of surfaces and interfaces through quantitative measurement and analysis. In this review, we present the current status of and discuss important recent developments in the measurement of intrinsic SFG spectral lineshapes and formulations for polarization measurements and orientational analysis of SFG-VS spectra. The focus of this review is topresent a coherent description of SFG-VS and discuss the main concepts and issues that can help advance this technique as a quantitative analytical research tool for revealing the chemistry and physics of complex molecular surfaces and interfaces. © 2015 by Annual Reviews.

The global market for wind energy has increased exponentially in the past few decades, and there is a continuous effort to develop cost-effective materials with higher strength to mass ratio for wind blades. With unique structural and transport properties, carbon nanotubes (CNTs) have attracted much interest as the reinforcement to develop polymer-based nanocomposites delivering exceptional mechanical properties and multi-functional characteristics. In light of previous and current status in carbon-based materials, herein the suitabilities of CNT/polymer nanocomposites for wind blade materials are analyzed. Special emphasis is placed on the mechanical, fatigue, electrical, thermal and barrier properties of CNT/polymer nanocomposites, which are important considerations when selecting suitable materials for wind blades with larger rotary radius. The application of CNT/polymer nanocomposites as sensory materials for the monitoring of defects in composite structures is also discussed. Finally, based on the progress made so far, some suggestions paving the way for the large commercialization of these nanocomposites for wind blades are presented. © 2013 Elsevier Ltd.

A study is conducted to provide comprehensive information about one-dimensional (1D) self-assembly of PIs, providing a deep understanding of recent progress, along with possible challenges and breakthroughs coming in the future. The basic molecular design and synthetic strategies of PI molecules are described. A complete overview of the 1D self-assembly methodology of PIs then is presented, followed by a summary of the inspiring applications and relevant prospects of the 1D assemblies in photonic and electronic devices.

Anatase TiO 2 nanocuboids wholly exposed with high-energy {001} and {100} facets were successfully synthesized by a novel, environmentally benign synthetic strategy using acid-delaminated vermiculite (DVMT) and tetramethylammonium hydroxide as synergistic morphology-controlling reagents, where the DVMT layers act as effective hard template selectively stabilizing the {001} facets of TiO 2. © 2012 The Royal Society of Chemistry.
