Reaction Mechanism of Cl-2 and 1-Alkyl-3-methylimidazolium Chloride Ionic Liquids
No full textSystems containing 1-alkyl-3-methylimidazolium chloride ionic liquid and chlorine gas were investigated. Using relativistic density functional theory, we calculated the formation mechanism of trichloride and hydrogen dichloride anions in an Emim(+)Cl(-) + Cl-2 system. Emim(+)Cl(3)(-) forms without energy barriers. The more stable species ClEmim(+)HCl(2)(-) forms through chlorine substitution. Substitution of a H on the imidazolium ring is much easier than substitution on the alkyl side chains. Infrared, Raman, ESI-MS, and H-1 NMR spectra were measured for EmimCl, BmimCl, and DmimCl with and without Cl-2 gas. The coexistence of Cl-3(-) and HCl2-, as well as chlorine-substituted cations, was confirmed by detection of their spectroscopic signals in the Cl-2 added ionic liquids. Cl substitution appears less serious for cations with longer side chains.Chemistry, PhysicalPhysics, Atomic, Molecular & ChemicalSCI(E)EIPubMed3ARTICLE4613452-1346611
Probing modified gravity theories with ISW and CMB lensing
No full textWe use the optimized skew-spectrum as well as the skew-spectra associated with the Minkowski functionals to test the possibility of using the cross-correlation of the integrated Sachs-Wolfe effect (ISW) and lensing of the cosmic microwave background (CMB) radiation to detect deviations in the theory of gravity away from General Relativity (GR). We find that the although both statistics can put constraints on modified gravity, the optimized skewspectra are especially sensitive to the parameter B0 that denotes the Compton wavelength of the scalaron at the present epoch. We investigate three modified gravity theories, namely the post-parametrized Friedmann formalism; the Hu-Sawicki model and the Bertschinger-Zukin (BZ) formalism. Employing a likelihood analysis for an experimental setup similar to ESA's Planck mission, we find that, assuming GR to be the correct model, we expect the constraints from the first two skew-spectra, S (0)l and S (1)l, to be the same: B0 < 0.45 at 95 per cent confidence level (CL) and B0 < 0.67 at 99 per cent CL in the BZ model. The third skew-spectrum does not give any meaningful constraint. We find that the optimal skew-spectrum provides much more powerful constraint, giving B0 < 0.071 at 95 per cent CL and B0 < 0.15 at 99 per cent CL, which is essentially identical to what can be achieved using the full bispectrum. © 2014 The Authors.

Open access self-archiving: An author study
No full textThis, our second author international, cross-disciplinary study on open access had 1296 respondents. Its focus was on self-archiving. Almost half (49%) of the respondent population have self-archived at least one article during the last three years. Use of institutional repositories for this purpose has doubled and usage has increased by almost 60% for subject-based repositories. Self-archiving activity is greatest amongst those who publish the largest number of papers. There is still a substantial proportion of authors unaware of the possibility of providing open access to their work by self-archiving. Of the authors who have not yet self-archived any articles, 71% remain unaware of the option. With 49% of the author population having self-archived in some way, this means that 36% of the total author population (71% of the remaining 51%), has not yet been appraised of this way of providing open access. Authors have frequently expressed reluctance to self-archive because of the perceived time required and possible technical difficulties in carrying out this activity, yet findings here show that only 20% of authors found some degree of difficulty with the first act of depositing an article in a repository, and that this dropped to 9% for subsequent deposits. Another author worry is about infringing agreed copyright agreements with publishers, yet only 10% of authors currently know of the SHERPA/RoMEO list of publisher permissions policies with respect to self-archiving, where clear guidance as to what a publisher permits is provided. Where it is not known if permission is required, however, authors are not seeking it and are self-archiving without it. Communicating their results to peers remains the primary reason for scholars publishing their work; in other words,
researchers publish to have an impact on their field. The vast majority of authors (81%) would willingly comply with a mandate from their employer or research funder to deposit copies of their articles in an institutional or subject-based repository. A further 13% would comply reluctantly; 5% would not comply with such a mandate

Characteristics of Water Quality in Chang Jiang，Huang Ho，Tai Hu and Dong Hu
No full text:In order to understand on characterstics of water quality of Chang Jiang，H uang Ho，T ai Hu and Dong Hu in People's Republic of China，c ontentsof Na ，K， Ca，M g，C l，S O.，a nd Si02 were determined. Water samples were collected from 3s tations in Huang Ho on August 1986 and 9i n Chang Jiang，2 i n Tai Hu and 1 in Dong Hu on August 1988. The water from Chang ]iang and Huang Ho were content three times higher in Ca and one-third lower in Si content than that ordinarily found in Japanese rivers. The Na and Cl contents were distinctly higher with waters from Tai Hua nd Dong Hut han from Chang Jiang，su ggesting the effect of human activities around the watershed of lakes. Using the key diagram based on cation :an ion equivalent ratio，wa ter types were studied. Of the waters from 17 stations，1 6 (1 in Huang .Ho excepted) were calcium -bicarbonate type which has the general quality of inland water. The water from the station in the lower stream of Hanung Ho was chracterizied as calciumnonbicarbonate type. This might reflect the dissolution of SO. from loessArticle環境科学年報11:131-139(1989)research repor
Progress of international hydrogen production network for the thermochemical Cu–Cl cycle
No full textThis paper presents recent advances by an international team which is developing the thermochemical copper–chlorine (Cu–Cl) cycle for hydrogen production. Development of the Cu–Cl cycle has been pursued by several countries within the framework of the Generation IV International Forum (GIF) for hydrogen production with the next generation of nuclear reactors. Due to its lower temperature requirements in comparison with other thermochemical cycles, the Cu–Cl cycle is particularly well matched with Canada's Generation IV reactor, SCWR (Super-Critical Water Reactor), as well as other heat sources such as solar energy or industrial waste heat. In this paper, recent developments of the Cu–Cl cycle are presented, specifically involving unit operation experiments, corrosion resistant materials and system integration.Atomic Energy of Canada LimitedOntario Research Excellence FundNatural Sciences and Engineering Research Council of CanadaUniversity Network of Excellence in Nuclear Engineering (UNENE)Canada Research Chairs progra
