Ordered mesoporous inorganic non-oxide materials attract increasing interest due to their plenty of unique properties and functionalities and potential applications. Lots of achievements have been made on their synthesis and structural characterization, especially in the last five years. In this critical review, the ordered mesoporous non-oxide materials are categorized by compositions, including non-oxide ceramics, metal chalcogenides, metal nitrides, carbides and fluorides, and systematically summarized on the basis of their synthesis approaches and mechanisms, as well as properties. Two synthesis routes such as hardlating (nanocasting) and softlating (surfactant assembly) routes are demonstrated. The principal issues in the nanocasting synthesis including the template composition and mesostructure, pore surface chemistry, precursor selection, processing and template removal are emphatically described. A great number of successful cases from the softlating method are focused on the surfactant liquid-crystal mesophases to synthesize mesostructured metal chalcogenide composites and the inorganic-block-organic copolymer self-assembly to obtain non-oxide ceramics (296 references). © 2011 The Royal Society of Chemistry.

In the wake of the financial crisis one of the major challenges faced by policymakers in Europe and around the world is re-kindling economic growth and innovation. Recent research portrays economic growth as a process of evolution of ecosystems of technologies and industrial capabilities. This research has also shown a strong relationship between the development of the complexity of economies in a globalized market and overall output growth. ICT based tools, in particular complex systems analysis, simulation, systems science methods, and big data capabilities offer policymakers new opportunities to empirically map technology and capability ecosystems of countries and industrial sectors, analyse their structure, understand their dynamics, measure economic complexity, and design policy interventions more likely to have positive impacts on growth over time. This project proposes to apply ICT tools in this way to yield insights on the industrial competitiveness and fragility of countries, the evolution of technologies and capabilities, the network of products, the adaptability of companies, and the ecology of E-commerce. In particular, E-commerce provides an important example of the active involvement of citizen in terms of their feedbacks on products and companies. The project will be a European and global collaboration amongst a network of researchers highly experienced in these topics. The teams involved represent an interdisciplinary consortium in which various research lines will be integrated in a network of collaborative effort to address challenging problems for a new vision of a data driven fundamental economics in a strongly connected, globalised world. The results of the project will provide a novel basis for economic forecasting and risk analysis for countries, companies and technological sectors, and they will also provide a new perspective for growth and innovation policymaking.

This review focuses on classifying different types of long wavelength absorbing BODIPY dyes based on the wide range of structural modification methods that have been adopted, and on tabulating their spectral and photophysical properties. The structure-property relationships are analyzed in depth with reference to molecular modeling calculations, so that the effectiveness of the different structural modification strategies for shifting the main BODIPY spectral bands to longer wavelengths can be readily compared, along with their effects on the fluorescence quantum yield (ΦF) values. This should facilitate the future rational design of red/NIR region BODIPY dyes for a wide range of different applications. © 2014 The Royal Society of Chemistry.

Silicene is the graphene-like silicon nanosheet, which has been synthesized very recently [B. Lalmi, H. Oughaddou, H. Enriquez, A. Kara, S. Vizzini, B. Ealet, and B. Aufray, Appl. Phys. Lett. 97, 223109 (2010)]. Using first-principles calculations, we systematically investigate the structures and properties of fluorinated and hydrogenated silicene, the silicon analogues of graphane. Different from the carbon-counterpart, the fluorination prefers the conformation with a zigzag-line buckling, while the hydrogenation keeps the chair conformation similar to graphane. A direct band gap is opened in the silicene fluoride, and the gap values can be continuously modulated by the strain. While for the hydride, a strain-induced indirect-to-direct band gap transition is found. © 2012 American Institute of Physics.

We investigate the scattering of polychromatic plane light wave incident upon a system formed with two anisotropic particles in different distance. The analytical expression for the spectrum of the scattered field is derived. Numerical examples show the phenomena of spectral shifts and spectral switches of the scattered field. The influences of the scattering direction and the difference of the particles on the spectral switch are illustrated. © 2013 Optical Society of America.

FAM110C belongs to a family of proteins that regulates cell proliferation. In the present study, the spatiotemporal expression pattern of FAM110C and its potential role were examined during the periovulatory period. Immature female rats were injected with equine chorionic gonadotropin (eCG) followed by human chorionic gonadotropin (hCG) and ovaries or granulosa cells were collected at various times after hCG administration (n = 3/time point). Expression levels of Fam110c mRNA and protein were highly induced both in intact ovaries and granulosa cells at 8 to 12 h after hCG treatment. In situ hybridization analysis demonstrated Fam110c mRNA expression was induced in theca and granulosa cells at 4 h after hCG, primarily localized to granulosa cells at 8 h and 12 h, and decreased at 24 h after hCG. There was negligible Fam110c mRNA detected in newly forming corpora lutea. In rat granulosa cell cultures, hCG induced expression of Fam110c mRNA was inhibited by RU486, whereas NS398 and AG1478 had no effect, suggesting that Fam110c expression is regulated in part by the progesterone receptor pathway. Promoter activity analysis revealed that an Sp1 site was important for the induction of Fam110c expression by hCG. Overexpression of FAM110C promoted granulosa cells to arrest at the G(1) phase of the cell cycle but did not change progesterone levels. In summary, hCG induces Fam110c mRNA expression in granulosa cells by activation of an Sp1-binding site and the actions of progesterone. Our findings suggest that FAM110C may control granulosa cell differentiation into luteal cells by arresting cell cycle progression.

We propose a way for implementing quantum information transfer with two superconducting flux qubits by coupling them to a resonator. This proposal does not require adjustment of the level spacings or uniformity in the device parameters. Moreover, neither adiabatic passage nor a second-order detuning is needed by this proposal, thus the operation can be performed much faster when compared with the previous proposals. © 2010 The American Physical Society.

The observation of the stereochemistry of silicon-stereogenic silanes dates back to the pioneering work by Kipping in 1907.[1] However, despite many significant efforts in the past hundred years toward finding new synthetic methodologies to Si-stereogenic silanes, they are still few in number. The enantioselective preparation of these silanes and their functionalized derivatives was not at all a trivial task and remained restricted to optical and kinetic resolution.[1c,d, 2] Undoubtedly, the exploration of new and efficient catalytic methods with high enantioselectivity remains one of the principal challenges in asymmetric catalysis. © 2012 Wiley-VCH Verlag GmbH & Co.

The session initiation protocol (SIP) is an authentication protocol used in 3G mobile networks. In 2009, Tsai proposed an authenticated key agreement scheme as an enhancement to SIP. Yoon et al. later pointed out that the scheme of Tsai is vulnerable to off-line password guessing attack, Denning-Sacco attack, and stolen-verifier attack and does not support perfect forward secrecy (PFS). Yoon et al. further proposed a new scheme with PFS. In this paper, we show that the scheme of Yoon et al. is still vulnerable to stolen-verifier attack and may also suffer from off-line password guessing attack. We then propose several countermeasures for solving these problems. In addition, we propose a new security-enhanced authentication scheme for SIP. Our scheme also maintains low computational complexity. Copyright © 2011 John Wiley & Sons, Ltd.
