Sa dernière exposition, intitulée Notre histoire, qui a eu lieu à la Galerie de l’Université du Québec à Montréal, prolonge ce travail de provocation d’un jugement critique où il s’approprie cette fois la forme muséale. Sur le mode de la parodie, il interroge le rapport à l’histoire et à la mémoire de la société québécoise et canadienne, tout en mettant le visiteur de cette exposition face au pouvoir idéologique du musée. Notre article se divise en deux parties. Dans un premier temps, nous laisserons la parole à l’artiste – sous la forme d’un entretien –, qui reviendra sur la genèse de ce projet, sur son processus et le contexte dans lequel il a réalisé cette exposition. Puis, dans un second temps, nous présenterons un bref compte rendu critique de cette exposition en nous intéressant particulièrement à l’utilisation de cette forme muséale et aux enjeux idéologiques et critiques qui la traversent.

Cinc edicions del Venturós Pelegrí a la Bibliothèque Mazarine de París
Authors: Mahiques Climent Joan 
Published: June 2015

Resum: El ms. 4504 de Bibliothèque Mazarine de París aplega, per una banda, cinc exemplars impresos de la “Peregrinació del Venturós Pelegrí” ab les “Cobles de la Mort” i, per altra banda, una còpia manuscrita parcial del Venturós Pelegrí amb una traducció francesa incompleta a cura de Josep Tastu (1787-1849), que s’encarregà de compilar tots els materials del volum. A banda de presentar el contingut general del ms. 4504, descrivim amb detall cada una de les cinc edicions, posant especial èmfasi en la més antiga, probablement datada de mitjan segle XVI o poc després. Pel fet d’ésser el testimoni més antic que coneixem del Venturós Pelegrí, aquest exemplar acèfal i àpode, estampat a línia seguida amb tres gravats encara visibles, aporta dades rellevants per al coneixement de les vies de difusió d’aquesta obra als segles XVI-XVII. Paraules clau: Edad Moderna, Poesia catalana, Impremta, Xilografia, Josep Tastu. Abstract: The Ms. 4504 of the Bibliothèque Mazarine in Paris contains, on the one hand, five printed copies of the “Peregrinació del Venturós Pelegrí” ab les “Cobles de la Mort” and, on the other hand, a partial hand-written copy of the Venturós Pelegrí with an incomplete French translation by Josep Tastu (1787-1849), who compiled all the materials of this volume. Apart from presenting the general content of the ms. 4504, we describe in detail the five editions with particular emphasis on the oldest one, probably dating from the mid-sixteenth century or shortly thereafter. This printed book, now acephalous and apodous, in which the lines go all the way across the page, still preserves three woodcuts. As the earliest witness we know of the Venturós Pelegrí, this printed copy provides some evidences to understand the dissemination of this work during the sixteenth and seventeenth centuries.Keywords: Modern Age, Catalan poetry, Printing, Woodcut, Josep Tastu.

«Temeritats enlluernadores»: La ciutat en la poesia de Bartomeu Rosselló-Pòrcel
Authors: Bou Enric 
Published: June 2015

Resum: La poesia de Rosselló-Pòrcel és una obra de dimensió limitada, però d’una gran diversitat. En els últims anys s’ha estudiat amb precisió la presència d’un llegat postsimbolista. En aquest article s’analitza un aspecte menystingut: el sentit de la presència de mons urbans en la poesia de Rosselló-Pòrcel. El poeta experimenta amb un nou concepte de la metàfora i incorpora els elements que componen l'escenari urbà nomenats amb ajuda d'un lèxic despullat del tabú del prosaisme. L’adjectivació, a més, farà possible unir l'experiència del que és descriptiu amb la desrealització de l'objecte contemplat. L’anàlisi detinguda de tres poemes complementa la reflexió. Paraules clau: Poesia urbana, postsimbolisme Abstract: Rosselló-Pòrcel’s poetry is a work of limited extension, but of great diversity. In recent years critics have studied with precision the presence of a post-symbolist legacy. In this article I take a look at an undervalued aspect of it: the meaning and uses of urban worlds in his poetry. The poet experimented with a new concept of metaphor and incorporates elements from the urban scene using a lexicon that includes prosaic elements. Adjectives make possible the combination of description with object contemplation. The thorough analysis of three poems completes the re-evaluation. Keywords: Poetry City PostSymbolism
Spatial variation of amount effect over peninsular India and Sri Lanka: Role of seasonality
Authors: Lekshmy P. R. , Midhun M. , Ramesh R. 
Published: June 2015

AbstractThe relationship between rain amount and rain δ18O of monsoon rain (amount effect) helps to reconstruct past monsoon variability from proxies (e.g., tree rings and speleothems). Analysis of new (and published) data of the δ18O of monsoon rains and vapor at nine stations shows that in regions of distinct seasonality in precipitation (e.g., peninsular India), the noise in such reconstructions can be minimized by a careful selection of sites. Peninsular India receives rain from both the Indian summer monsoon (ISM) and the northeast monsoon (NEM). Significant amount effect is observed only where the NEM rainfall is larger than or comparable to ISM rainfall. This is due to the higher quantity of NEM rain with more depleted 18O relative to ISM rain. NEM rain is more depleted in 18O because of cyclonic activity over Bay of Bengal, and the 18O depletion of Bay of Bengal surface waters due to post‐ISM river runoff.

This oxidative cross dehydrative coupling (CDC) reaction was promoted by 2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone (DDQ) and provided rapid access to a broad range of nitriles in good to excellent yields.magnified image
Complications of non‐occlusive mesenteric ischaemia
Authors: Weledji Elroy Patrick 
Published: June 2015

CaseA 65‐year‐old arteriopath with a history of myocardial infarction 5 months previously presented with classical signs of mesenteric infarction that led to a right hemicolectomy with an end ileostomy.OutcomePostoperative complications occurred due to unusually large volume ileostomy output in the subsequent 4 weeks, resulting in severe volume depletion and the sequelae that required intensive care support. These were triggered and prolonged by two episodes of intra‐abdominal sepsis.ConclusionsSepsis‐induced high ileostomy output following intestinal resection for non‐occlusive mesenteric ischaemia is a serious complication. Early restoration of intestinal continuity following bowel resection for established infarction may prevent this complication.

Published: June 2015

AbstractA method for the region‐selective deposition of nanoparticles (NPs) by the Huisgen 1,3‐dipolar cycloaddition is presented. The approach enables defined stacking of various oxide NPs in any order with control over layer thickness. Thereby the reaction is performed between a substrate, functionalized with a self‐assembled monolayer of an azide‐bearing phosphonic acid (PA) and aluminum oxide (AlOx) NPs functionalized with an alkyne bearing PA. The layer of alkyne functionalized AlOx NPs is then used as substrate for the deposition of azide‐functionalized indium tin oxide (ITO) NPs to provide a binary stack. This progression is then conducted with alkyne‐functionalized CeO2 NPs, yielding a ternary stack of NPs with three different NP cores. The stacks are characterized by AFM and SEM, defining the region‐selectivity of the deposition technique. Finally, these assemblies have been tested in devices as a dielectric to form a capacitor resulting in a dramatic increase in the measured capacitance.
A Family of High‐Efficiency Hydrogen‐Generation Catalysts Based on Ammonium Species

Published: June 2015

AbstractDevelopment of highly active, low cost, ecologically friendly, and durable homogenous catalysts for hydrogen generation from hydrolysis of borohydride is one of the most desirable pathways for future hydrogen utilization. The unexpected catalytic activities of inorganic ammonium species and the corresponding mechanisms underpinning them are studied. The catalytic activities of the ammonium species are higher than or comparable to those of mostly investigated noble‐metal/transition‐metal catalysts (such as Pd, Pt, Ni, and Co) but are considerably cheaper, more environmentally friendly, and more readily available. Quantum chemical calculations indicate that the unique ammonium‐induced reaction pathway involved with a barrierless elementary reaction at the reaction entrance and the formation of the highly active intermediate BH3 are responsible for the unexpected catalytic activities and the significantly accelerated hydrogen generation.

Published: June 2015

AbstractUnprecedented catalytic reactivity of actinide coordination complexes toward heterocumulenes, such as carbodiimides, isocyanates, and isothiocyanates is reported. The mono(imidazolin‐2‐iminato) thorium(IV) complex [Th(ImDippN){N(SiMe3)2}3] (1) was applied as a precatalyst for the addition of EH (E=N, P, S) bonds to the YCX core (Y=R2N; X=NR2, O, S) of carbodiimides, isocyanates, and isothiocyanates. The respective insertion products were obtained in high yields under mild reaction conditions, with complex 1 displaying high tolerance toward functional groups and heteroatoms.

Published: June 2015

AbstractA novel class of near‐infrared fluorescent contrast agents was developed. These agents target cartilage with high specificity and this property is inherent to the chemical structure of the fluorophore. After a single low‐dose intravenous injection and a clearance time of approximately 4 h, these agents bind to all three major types of cartilage (hyaline, elastic, and fibrocartilage) and perform equally well across species. Analysis of the chemical structure similarities revealed a potential pharmacophore for cartilage targeting. Our results lay the foundation for future improvements in tissue engineering, joint surgery, and cartilage‐specific drug development.
High‐Conductivity Two‐Dimensional Polyaniline Nanosheets Developed on Ice Surfaces

Published: June 2015

AbstractA new method to develop two‐dimensional PANI nanosheets using ice as a removable hard template is presented. Distinctly high current flows of 5.5 mA at 1 V and a high electrical conductivity of 35 S cm−1 were obtained for the polyaniline (PANI) nanosheets, which marked a significant improvement from previously values on other PANIs reported over the past decades. These improved electrical properties of ice‐templated PANI nanosheets were attributed to the long‐range ordered edge‐on π‐stacking of the quinoid ring, ascribed to the ice surface‐assisted vertical growth of PANI. The unprecedented advantages of the ice‐templated PANI nanosheets are two‐fold. First, the PANI nanosheet can be easily transferred onto various types of substrates via float‐off from the ice surfaces. Second, PANI can be patterned into any shape using predetermined masks, and this is expected to facilitate the eventual convenient and inexpensive application of conducting polymers in versatile electronic device forms.
Copper‐Catalyzed Trifluoromethylazidation of Alkynes: Efficient Access to CF3‐Substituted Azirines and Aziridines
Authors: Wang Fei , Zhu Na , Chen Pinhong , Ye Jinxing , Liu Guosheng 
Published: June 2015

AbstractA novel method for convenient access to CF3‐containing azirines has been developed, and involves a copper‐catalyzed trifluoromethylazidation of alkynes and a photocatalyzed rearrangement. Both terminal and internal alkynes are compatible with the mild reaction conditions, thus delivering the CF3‐containing azirines in moderate to good yields. The azirines can be converted into various CF3‐substituted aziridines.
The Retro‐Hydroformylation Reaction
Authors: Kusumoto Shuhei , Tatsuki Toshiumi , Nozaki Kyoko 
Published: June 2015

AbstractHydroformylation, a reaction that adds carbon monoxide and dihydrogen across an unsaturated carbon–carbon multiple bond, has been widely employed in the chemical industry since its discovery in 1938. In contrast, the reverse reaction, retro‐hydroformylation, has seldom been studied. The retro‐hydroformylation reaction of an aldehyde into an alkene and synthesis gas (a mixture of carbon monoxide and dihydrogen) in the presence of a cyclopentadienyl iridium catalyst is now reported. Aliphatic aldehydes were converted into the corresponding alkenes in up to 91 % yield with concomitant release of carbon monoxide and dihydrogen. Mechanistic control experiments indicated that the reaction proceeds by retro‐hydroformylation and not by a sequential decarbonylation–dehydrogenation or dehydrogenation–decarbonylation process.

Published: June 2015

AbstractPolycyclic aromatic compounds containing fully unsaturated five‐membered ring(s) have been intensively studied because of their unique properties, which include high electron affinity and reactivity. Reported herein is an efficient route for the synthesis of tetrabenzo‐fused pyracylene, which comprises pyracylene and tetracene segments, using intramolecular oxidative CH coupling. It was shown to possess high electron affinity and was found to undergo addition reactions with n‐butyllithium or benzyne. These reactions led to either a 1,4‐addition compound or triptycene‐type adduct with a curved or planar π‐system, respectively. Although these compounds exhibited similar sky‐blue emissions in a dilute solution, the emission band of the 1,4‐addition compound was significantly red‐shifted in the solid state and exhibited intense yellow emission attributable to the excimer, while the triptycene‐type adduct retained the intense blue color emission in the solid state.

Published: June 2015

AbstractA new strategy for highly concise, convergent, and enantioselective access to polydeoxypropionates has been developed. ZACA‐Pd‐catalyzed vinylation was used to prepare smaller deoxypropionate fragments, and then two key sequential Cu‐catalyzed stereocontrolled sp3–sp3 cross‐coupling reactions allowed convergent assembly of smaller building blocks to build‐up long polydeoxypropionate chains with excellent stereoselectivity. We employed this strategy for the synthesis of phthioceranic acid, a key constituent of the cell‐wall lipid of Mycobacterium tuberculosis, in just 8 longest linear steps with full stereocontrol.
Synthesis and characterization of polyphenylaminophosphazene and fluorinated polyarylaminophosphazene
Authors: Zhou Lisheng , Zhang Guangcheng , Li Jianwei , Zhao Long , Zhang Xinyu , Wei Xuan 
Published: June 2015

ABSTRACTTwo polyarylaminophosphazenes, poly[bis(phenylamino)phosphazene] (PBAP) and poly[bis(p‐trifluoroethoxyphenylamino)phosphazene] (PBTAP), were successfully synthesized by ring‐opening polymerizations and nucleophilic substitution reactions. Their chemical structures, thermal properties, and surface properties were investigated by NMR, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and water contact angles (WCA). The results indicate that the glass‐transition temperature (Tg), thermal stability, and WCAs of PBAP and PBTAP presented obviously differences; this suggested that PBTAP possessed the lower Tg and higher contact angle than PBAP. This was attributed to the influence of trifluoroethoxy at the para position of aniline. TGA measurements indicated that PBAP possessed a higher thermal stability than PBTAP; this was attributed to the strong electron‐withdrawing influence of the trifluoroethoxy. © 2015 Wiley Periodicals, Inc.

Resorcinol formaldehyde xerogels modified with mercapto functional groups as mercury adsorbent

Published: June 2015

ABSTRACTResorcinol formaldehyde xerogels are modified by mercaptopropyl‐trimethoxysilane during the sol–gel process used to produce the xerogel. The chemical modification is confirmed by Fourier‐transform infrared spectroscopy. The xerogel is then used to adsorb mercury ions from aqueous solutions. The effects of the molar ratios of the precursors as well as the catalyst and the modifier are studied on the textural properties of the xerogel and the adsorption efficiency. It is shown that the chemical modification of the resorcinol formaldehyde xerogels creates the chemical sites on the structure of the xerogel to adsorb more mercury ions and increase the adsorption efficiency. At the same time, chemical modification decreases the xerogel surface area which results in a reduction of the mercury adsorption. Therefore, there exists an optimum value for the chemical modification of the xerogel to achieve the highest adsorption efficiency. Adsorption kinetics as well as equilibrium isotherm of xerogels were examined using pseudo‐first‐ and second‐order kinetic equations, and Freundlich and Langmuir isotherm models. The adsorption kinetics was found to follow the pseudo‐second‐order kinetic equations. The experimental data was also fitted into the Longmuir model more precisely comparing the Freundlich model. Finally, a series of mercury adsorption–desorption tests proved that the optimized mercapto‐modified resorcinol formaldehyde xerogel was an efficient reusable adsorbent for mercury ions. © 2015 Wiley Periodicals, Inc.

Published: June 2015

AbstractCarbon supported nanostructured palladium or palladium alloys are considered the best performing anode electrocatalysts currently employed in alkaline electrolyte membrane direct ethanol fuel cells (AEM‐DEFCs). High initial peak power densities are generally obtained as Pd preferentially favors the selective oxidation of ethanol forming acetate thus avoiding strongly poisoning intermediates such as CO. However, few studies exist that investigate DEFC performance in terms of both energy efficiency and discharge energy density, as well as power density depending on the concentration of fuel. In this paper we have determined such parameters for room temperature air breathing AEM‐DEFCs equipped with Pd based anodes, anion exchange membranes and FeCo/C cathode electrocatalysts. Combined with the optimization of the fuel composition a maximum energy efficiency of ≈7 % was obtained for this AEM‐DEFC. Such a performance suggests that devices of this type are suitable for supplying low power applications such as small portable electronic devices.
