Metal cations are the simplest, but most versatile, cofactors in protein biochemistry with a plethora of distinctive properties. Intracellular and extracellular fluids contain a mixture of metal cations present in different concentrations. Properties of the metal-binding site such as its relative rigidity and solvent accessibility, as well as the type, number, orientation, and protonation state of the metal coordinating ligands, which determine the metal cavity size, geometry, and charge density, affect metal ion selectivity. In several cases, the host protein alone is not able to withstand attacks from biogenic or alien metal cations, which could displace the cognate metal cofactor from the binding site. Whereas the metal-ligand interaction energy becomes less favorable in going down a main group, it becomes more favorable in going across a row in the periodic table, as the net positive charge on the metal increases, yet monovalent ions can still displace divalent ions in certain proteins.

This review paper covers recent publications on the developments of highly proton-conductive sulfonated polymers for proton exchange membrane (PEM) fuel cells. The PEMs presenting proton conductivities exceeding that of Nafion membranes are especially focused on. The proton conductivities of PEMs have been correlated to their ion exchange values and morphological phase-separation. Formation of ionic channels is an effective approach to develop highly proton-conductive PEMs. The approaches could be grouped into (1) developments of microphase-separation with block copolymers, (2) side-chain and grafted sulfonated polymers, and (3) locally and densely sulfonated polymers. Formation of nanocomposites of PEMs with nanofillers has also shown great ability to increase the proton conductivities of the existed PEMs. Besides proton conductivities, the formation of nanocomposites also improves some PEM properties including mechanical strength, dimensional stability, and oxidative stability. The discussed publications have provided promising PEMs for the development of high performance fuel cells. This journal is © The Royal Society of Chemistry 2012.

The easily electronically and sterically tunable β-diketiminates are widely used auxiliary ligands for the creation of a wide range of metal complexes with various oxidation states in all groups of the periodic table. This review article highlights the recent advances of univalent β-diketiminatometal complexes. Such low-valent metals supported by β-diketiminates display remarkable metal-metal bonding, organic functionality and small molecule activations, reactivity relevant to biological active sites, and catalytic reactivity. © 2011 Elsevier B.V.

Nanoantennas for visible and infrared radiation can strongly enhance the interaction of light with nanoscale matter by their ability to efficiently link propagating and spatially localized optical fields. This ability unlocks an enormous potential for applications ranging from nanoscale optical microscopy and spectroscopy over solar energy conversion, integrated optical nanocircuitry, opto-electronics and density-of-states engineering to ultra-sensing as well as enhancement of optical nonlinearities. Here we review the current understanding of metallic optical antennas based on the background of both well-developed radiowave antenna engineering and plasmonics. In particular, we discuss the role of plasmonic resonances on the performance of nanoantennas and address the influence of geometrical parameters imposed by nanofabrication. Finally, we give a brief account of the current status of the field and the major established and emerging lines of investigation in this vivid area of research. © 2012 IOP Publishing Ltd.

The study described herein uses US Patent and Trademark Office data to assess variations in technological innovation capabilities, and their influence on market performance, among leading TFT-LCD producers in Japan, Korea, and Taiwan. The empirical results suggest that TFT-LCD producers in Korea and Taiwan built innovation capabilities by creating complementary knowledge for Japanese firms, whose technologies lead the way in the industry. The results also show that latecomers sought to expand production by selecting certain technological fields, but that they exploited these fields in different ways. Specifically, Korean conglomerates increased their scale of technology in order to improve their technological positions, while Taiwanese producers pursued innovations that strengthened their technological efficiency. While Japanese firms led the way in terms of both technology and market share during the 1990s, they then evolved to become merely technological leaders from 2000 onwards. However, Japanese firms have since renewed their business strategies to counter the aggressive market expansion of their competitors by strengthening the protection of their intellectual property rights through inter-keiretsu collaborations in technological niches, and by securing leadership in the market in high value-added key components in order to retain more of the profits from their own innovations. Four policy imperatives for both technology leading and latecomer countries regarding the development of sustainable industries associated with the industrial cycle and market dynamics are discussed. © 2011 Elsevier B.V.
