Changes in publication languages and citation practices and their effect on the scientific impact of Russian science (1993–2010)
Authors: Kirchik Olessia , Gingras Yves , Larivière Vincent
Published: March 2012

This article analyzes the effects of publication language on the international scientific visibility of Russia using the Web of Science (WoS). Like other developing and transition countries, it is subject to a growing pressure to “internationalize” its scientific activities, which primarily means a shift to English as a language of scientific communication. But to what extent does the transition to English improve the impact of research? The case of Russia is of interest in this respect as the existence of many combinations of national journals and languages of publications (namely, Russian and English, including translated journals) provide a kind of natural I experiment to test the effects of language and publisher's country on the international visibility of research through citations as well as on the referencing practices of authors. Our analysis points to the conclusion that the production of original English‐language papers in foreign journals is a more efficient strategy of internationalization than the mere translation of domestic journals. If the objective of a country is to maximize the international visibility of its scientific work, then the efforts should go into the promotion of publication in reputed English‐language journals to profit from the added effect provided by the Matthew effect of these venues.
Complex systems science: Dreams of universality, interdisciplinarity reality
Authors: Grauwin Sebastian , Beslon Guillaume , Fleury Éric , Franceschelli Sara , Robardet Celine , Rouquier Jean‐Baptiste , Jensen Pablo
Published: March 2012

Using a large database (∼215,000 records) of relevant articles, we empirically study the complex systems field and its claims to find universal principles applying to systems in general. The study of references shared by the articles allows us to obtain a global point of view on the structure of this highly interdisciplinary field. We show that its overall coherence does not arise from a universal theory, but instead from computational techniques and fruitful adaptations of the idea of self‐organization to specific systems. We also find that communication between different disciplines goes through specific “trading zones,” i.e., subcommunities that create an interface around specific tools (a DNA microchip) or concepts (a network).
The role of innovation and wealth in the net neutrality debate: A content analysis of human values in congressional and FCC hearings
Authors: Cheng An‐Shou , Fleischmann Kenneth R. , Wang Ping , Ishita Emi , Oard Douglas W.
Published: March 2012

Net neutrality is the focus of an important policy debate that is tied to technological innovation, economic development, and information access. We examine the role of human values in shaping the Net neutrality debate through a content analysis of testimonies from U.S. Senate and FCC hearings on Net neutrality. The analysis is based on a coding scheme that we developed based on a pilot study in which we used the Schwartz Value Inventory. We find that the policy debate surrounding Net neutrality revolves primarily around differences in the frequency of expression of the values of innovation and wealth, such that the proponents of Net neutrality more frequently invoke innovation, while the opponents of Net neutrality more frequently invoke wealth in their prepared testimonies. The paper provides a novel approach for examining the Net neutrality debate and sheds light on the connection between information policy and research on human values.
Development and validation of a Measure of Criminal Social Identity within a sample of Polish recidivistic prisoners
Authors: Boduszek Daniel , Adamson Gary , Shevlin Mark , Hyland Philip
Published: March 2012

Background

Social identity is a well‐established theoretical concept within psychological research; however, the role of criminal social identity has received far less research attention. One salient reason for the limited research relating to the concept of criminal social identity is the absence of a specific measure.

Aim

To develop and test the construct validity of a new measure of criminal social identity (MCSI) and to provide additional evidence relating to Cameron's three‐factor conceptualisation of social identity.

Method

The eight‐item MCSI was used to collect data from recidivists incarcerated in high‐security prison (N = 312) to assess criminal social identification. These data were subjected to confirmatory factor analysis.

Results

Three alternative models of criminal social identity were specified and tested in Mplus 6, and results revealed that the data were best explained by a three‐factor model of criminal social identity (cognitive centrality, in‐group affect and in‐group ties).

Conclusion

The current study is important in terms of future research in criminology and psychology because the MCSI provides the first reliable MCSI, which was developed and validated on a relatively large recidivistic prison sample. Copyright © 2012 John Wiley & Sons, Ltd.
The Nature of [PdCl2(C2H4)(H2O)] as an Active Species in the Wacker Process: New Insights from Ab Initio Molecular Dynamics Simulations
Authors: Kovács Gábor , Stirling András , Lledós Agustí , Ujaque Gregori
Published: March 2012

First‐principles molecular dynamics coupled with metadynamics have been used to gain a deeper insight into the reaction mechanism of the Wacker process by determining the nature of the active species. An explicit and dynamic representation of the aqueous solvent, which was essential for modeling this reaction, was efficiently included into the simulations. Prompted by our earlier results, which showed that the configuration of the catalytically active species [PdCl2(H2O)(C2H4)] was crucial in the subsequent steps of the Wacker process, herein we focused on the preceding equilibria that led to the formation of both the cis and trans isomers. Starting from the initial catalyst, [PdCl4]2−, the free‐energy barriers for the forward and backward reactions were calculated. These results confirmed the relevance of the trans intermediate in the reaction mechanism, whilst conversely, they showed that the cis configuration played no role in it. This sole participation of the trans intermediate has some very important implications; besides the mechanistic interpretation of the initial steps in the Wacker reaction mechanism, the analysis of these equilibria provides additional information about the chemical nature of these ligand‐substitution processes.

The synthesis and a joint experimental and theoretical study of the crystal structure and physical properties of the new ternary intermetallic compound TiGePt are presented. Upon heating, TiGePt exhibits an unusual structural phase transition with a huge volume contraction of about 10 %. The transformation is characterized by a strong change in the physical properties, in particular, by an insulator–metal transition. At temperatures below 885 °C TiGePt crystallizes in the cubic MgAgAs (half‐Heusler) type (LT phase, space groupF$\bar 4$3m,a=5.9349(2) Å). At elevated temperatures, the crystal structure of TiGePt transforms into the TiNiSi structure type (HT phase, space groupPnma,a=6.38134(9) Å,b=3.89081(5) Å,c=7.5034(1) Å). The reversible, temperature‐dependent structural transition was investigated by in‐situ neutron powder diffraction and dilatometry measurements. The insulator–metal transition, indicated by resistivity measurements, is in accord with band structure calculations yielding a gap of about 0.9 eV for the LT phase and a metallic HT phase. Detailed analysis of the chemical bonding in both modifications revealed an essential change of the Ti–Pt and Ti–Ge interactions as the origin of the dramatic changes in the physical properties.

Authors: Wang Xiao‐Jun , Krumeich Frank , Wörle Michael , Nesper Reinhard , Jantsky Laurent , Fjellvåg Helmer
Published: March 2012

The decomposition reaction of niobium(V) oxytrichloride ammoniate to the oxynitride of niobium in the 5+ oxidation state was developed in a methodological way. By combining elemental analysis, Rietveld refinements of X‐ray and neutron diffraction data, SEM and TEM, the sample compound was identified as approximately 5 nm‐diameter particles of NbO1.3(1)N0.7(1) crystallizing with baddeleyite‐type structure. The thermal stability of this compound was studied in detail by thermogravimetric/differential thermal analysis and temperature‐dependent X‐ray diffraction. Moreover, the electrochemical uptake and release by the galvanostatic cycling method of pure and carbon‐coated NbO1.3(1)N0.7(1) versus lithium was investigated as an example of an Li‐free transition‐metal oxynitride. The results showed that reversible capacities as high as 250 and 80 A h kg−1 can be reached in voltage ranges of 0.05–3 and 1–3 V, respectively. Furthermore, a plausible mechanism for the charge–discharge reaction is proposed.

Authors: Rudolf Marc , Wolfrum Silke , Guldi Dirk M. , Feng Lai , Tsuchiya Takahiro , Akasaka Takeshi , Echegoyen Luis
Published: March 2012

In recent years, endohedral metallofullerenes have attracted tremendous interest not only in physics and chemistry, but also in interdisciplinary areas, such as materials and biological sciences. In this concept article we highlight recent results on different endohedral metallofullerenes based on lanthanides and their derivatives. The chemical and excited state reactivities of endohedral metallofullerenes are discussed for various endohedral clusters. Most important is the part that covers spectroscopic and kinetic assays of reductive and oxidative charge transfer evolving from photoexcited electron donors and electron acceptors, respectively, in a variety of electron donor–acceptor conjugates. Towards this end, we refer to the applications of endohedral metallofullerenes in photovoltaic devices that feature greater efficiency than devices fabricated with empty fullerenes. Herein, we focus mainly on results obtained in the groups of Akasaka, Echegoyen, and Guldi.
Synthesis, Physicochemical Properties, and Hydrogen Bonding of 4(5)‐Substituted 1‐H‐Imidazole‐2‐carboxamide, a Potential Universal Reader for DNA Sequencing by Recognition Tunneling
Authors: Liang Feng , Li Shengqing , Lindsay Stuart , Zhang Peiming
Published: March 2012

We have developed a chemical reagent that recognizes all naturally occurring DNA bases, a so called universal reader, for DNA sequencing by recognition tunneling in nanopores.1 The primary requirements for this type of molecules are the ability to form non‐covalent complexes with individual DNA bases and to generate recognizable electronic signatures under an electrical bias. 1‐H‐imidazole‐2‐carboxamide was designed as such a recognition moiety to interact with the DNA bases through hydrogen bonding. In the present study, we first furnished a synthetic route to 1‐H‐imidazole‐2‐carboxamide containing a short ω‐functionalized alkyl chain at its 4(5) position for its attachment to metal and carbon electrodes. The acid dissociation constants of the imidazole‐2‐carboxamide were then determined by UV spectroscopy. The data show that the 1‐H‐imidazole‐2‐carboxamide exists in a neutral form between pH 6–10. Density functional theory (DFT) and NMR studies indicate that the imidazole ring exists in prototropic tautomers. We propose an intramolecular mechanism for tautomerization of 1‐H‐imidazole‐2‐carboxamide. In addition, the imidazole‐2‐carboxamide can self‐associate to form hydrogen bonded dimers. NMR titration found that naturally occurring nucleosides interacted with 1‐H‐imidazole‐2‐carboxamide through hydrogen bonding in a tendency of dG>dC≫dT>dA. These studies are indispensable to assisting us in understanding the molecular recognition that takes place in the nanopore where routinely used analytical tools such as NMR and FTIR cannot be conveniently applied.
Amine‐Catalyzed [3+2] Huisgen Cycloaddition Strategy for the Efficient Assembly of Highly Substituted 1,2,3‐Triazoles
Authors: Wang Lei , Peng Shiyong , Danence Lee Jin Tu , Gao Yaojun , Wang Jian
Published: March 2012

An enamine‐catalyzed strategy has been utilized to fully promote the Huisgen [3+2] cycloaddition with a broad spectrum of carbonyl compounds and azides, thereby permitting the efficient assembly of a vast pool of highly substituted 1,2,3‐triazoles. In particular, the employment of commonly used and commercially available carbonyl compounds has resulted in the introduction of a diverse set of functional groups, such as alkyl, aryl, nitrile, ester, and ketone groups, at the 1‐, 4‐, or 5‐positions of the 1,2,3‐triazole scaffold. This approach might be manipulated to access more useful and sophisticated heterocyclic compounds. Most significantly, the reaction process exhibits complete regioselectivity, with the formation of only one regioisomer.
Mechanistic Insight into the NN Bond‐Cleavage of Azo‐Compounds that was Induced by an AlAl‐bonded Compound [L2−AlIIAlIIL2−]
Authors: Zhao Yanxia , Liu Yanyan , Yang Ling , Yu Jian‐Guo , Li Shaoguang , Wu Biao , Yang Xiao‐Juan
Published: March 2012

An α‐diimine‐stabilized AlAl‐bonded compound [L2−AlIIAlIIL2−] (L=[{(2,6‐iPr2C6H3)NC(Me)}2]; 1) consists of dianionic α‐diimine ligands and sub‐valent Al2+ ions and thus could potentially behave as a multielectron reductant. The reactions of compound 1 with azo‐compounds afforded phenylimido‐bridged products [L−AlIII(μ2‐NPh)(μ2‐NAr)AlIIIL−] (2–4). During the reaction, the dianionic ligands and Al2+ ions were oxidized into monoanions and Al3+, respectively, whilst the [NAr]2− imides were produced by the four‐electron reductive cleavage of the NN double bond. Upon further reduction by Na, the monoanionic ligands in compound 2 were reduced to the dianion to give [(L2−)2AlIII2(μ2‐NPh)2Na2(thf)4] (5). Interestingly, when asymmetric azo‐compounds were used, the asymmetric adducts were isolated as the only products (compounds 3 and 4). DFT calculations indicated that the reaction was quite feasible in the singlet electronic state, but the final product with the triplet‐state monoanionic ligands could result from an exothermic singlet‐to‐triplet conversion during the reaction process.
Diffusion and Birefringence of Bioactive Dyes in a Supramolecular Guanosine Hydrogel

Published: March 2012

Transparent self‐standing supramolecular hydrogels were readily prepared by the potassium‐ion‐mediated self‐organization of guanosine and 8‐bromoguanosine whilst the individual components precipitated within a few hours. VT‐NMR spectroscopy showed that bromoguanosine was a superior gelator compared to guanosine. XRD analysis showed that gel formation was caused by stacked G‐quartets. AFM analysis revealed dendritic architectures of the nanofibers in the two‐component hydrogel network. DSC profiles showed that the hybrid hydrogels underwent sol–gel transition at lower temperature than the pure guanosine and bromoguanosine hydrogels. Interestingly, bioactive dyes, such as rose bengal, rhodamine‐6‐G, and fluorescein, could be diffused and released in a controlled manner. UV/Vis absorption and fluorescence spectroscopy and CLSM were used to investigate the diffusion behavior of dyes in the hydrogel network. These dyes exhibited strong birefringence in the gel network (0.07–0.1) as a result of the anisotropic organization.

Supercritical Fluid Deposition of Uniform PbS Nanoparticle Films for Energy‐Transfer Studies
Authors: Wang Joanna S. , Brown Gail J. , Hung Wei‐Chun , Wai Chien M.
Published: March 2012

Using supercritical fluid CO2 (Sc‐CO2) as a medium, PbS nanoparticles can be uniformly deposited on surfaces of various substrates. Sc‐CO2 deposition of PbS nanoparticles on carbon‐coated copper grids, into small holes in silicon, and formation of uniform PbS nanoparticle films on glass are described. Fluorescence spectra of PbS nanoparticles obtained from the films prepared by the Sc‐CO2 method indicate effective energy transfer between PbS nanoparticles of different sizes.
Recent Advances in Research Applications of Nanophase Hydroxyapatite
Authors: Fox Kate , Tran Phong A. , Tran Nhiem
Published: March 2012

Hydroxyapatite, the main inorganic material in natural bone, has been used widely for orthopaedic applications. Due to size effects and surface phenomena at the nanoscale, nanophase hydroxyapatite possesses unique properties compared to its bulk‐phase counterpart. The high surface‐to‐volume ratio, reactivities, and biomimetic morphologies make nano‐hydroxyapatite more favourable in applications such as orthopaedic implant coating or bone substitute filler. Recently, more efforts have been focused on the possibility of combining hydroxyapatite with other drugs and materials for multipurpose applications, such as antimicrobial treatments, osteoporosis treatments and magnetic manipulation. To build more effective nano‐hydroxyapatite and composite systems, the particle synthesis processes, chemistry, and toxicity have to be thoroughly investigated. In this Minireview, we report the recent advances in research regarding nano‐hydroxyapatite. Synthesis routes and a wide range of applications of hydroxyapatite nanoparticles will be discussed. The Minireview also addresses several challenges concerning the biosafety of the nanoparticles.
Nickel‐Promoted Tungsten Carbide Catalysts for Cellulose Conversion: Effect of Preparation Methods
Authors: Ji Na , Zheng Mingyuan , Wang Aiqin , Zhang Tao , Chen Jingguang G.
Published: March 2012

A series of Ni‐promoted W2C catalysts was prepared by means of a post‐impregnation method and evaluated for the catalytic conversion of cellulose into ethylene glycol (EG). Quite different from our previously reported Ni–W2C/AC catalysts, which were prepared by using the co‐impregnation method, the introduction of Ni by the post‐impregnation method did not cause catalyst sintering, but resulted in redispersion of the W component, which was identified and characterized by means of XRD, TEM, and CO chemisorption. The highly dispersed Ni‐promoted W2C catalyst was very active and selective in cellulose conversion into EG, with a 100 % conversion of cellulose and a 73.0 % yield in EG. The underlying reason for the enhanced catalytic performance was most probably the significantly higher dispersion of active sites on the catalyst.
Application of Y2O3:Er3+ Nanorods in Dye‐Sensitized Solar Cells
Authors: Wang Jiangli , Wu Jihuai , Lin Jianming , Huang Miaoliang , Huang Yunfang , Lan Zhang , Xiao Yaoming , Yue Gentian , Yin Shu , Sato Tsugio
Published: March 2012

Y2O3:Er3+ nanorods are synthesized by means of a hydrothermal method and then introduced into a TiO2 electrode in a dye‐sensitized solar cell (DSSC). Y2O3:Er3+ improves infrared light harvest via up‐conversion luminescence and increases the photocurrent of the DSSC. The rare earth ions improve the energy level of the TiO2 electrode through a doping effect and thus increase the photovoltage. The light scattering is ameliorated by the one‐dimensional nanorod structure. The DSSC containing Y2O3:Er3+ (5 wt %) in the doping layer achieves a light‐to‐electric energy conversion efficiency of 7.0 %, which is an increase of 19.9 % compared to the DSSC lacking of Y2O3:Er3+.
Simulation of absorption‐based surface plasmon resonance sensor in the Kretschmann configuration
Authors: Fekete Ádám
Published: March 2012

Surface plasmon resonance (SPR) has been efficiently applied for chemical and biosensing. In this paper, we present a new numerical simulation for the Kretschman type SPR sensors. In order to apply a circuit approach, we decomposed the problem by (1) using GAMESS to determine the dielectric function of the molecular layer, (2) using Computer Simulation Technology Microwave Studio to calculate the electromagnetic field. An interactive computer‐aided design technique is presented for Kretschmann‐type biosensors. Copyright © 2012 John Wiley & Sons, Ltd.
