Comparing Anode Gas Recirculation with Hydrogen Purge and Bleed in a Novel PEMFC Laboratory Test Cell Configuration

20-Apr-2015 | P. Koski, L. C. Pérez, J. Ihonen, Fuel Cells, 2015

Abstract In automotive‐type polymer electrolyte membrane fuel cell (PEMFC) systems, impurities and inert gases accumulate in the anode gas recirculation loop. Therefore, the impurity limits, dictated by the current hydrogen fuel specification (ISO 14687‐2:2012), also require quantification ...


Concomitant polymorphs of p-iso-propylcalix[4]arene

15-Apr-2015 | Vincent J. Smith; Charl G. Marais; Kinga Suwińska; Janusz Lipkowski; Agnieszka Szumna; Catharine Esterhuysen; Leonar ..., CrystEngComm, 2015

Sublimation of p-iso-propylcalix[4]arene under reduced pressure results in the concomitant formation of two new polymorphs (forms IIP and IIIP). Both forms consist of interdigitated dimers of calixarene molecules, as does the known form IP. Despite similar inclusion behaviour to that of ...


Effect of rim and web interaction on crack propagation paths in gears by means of XFEM technique

14-Apr-2015 | F. Curà, A. Mura, C. Rosso, Fatigue & Fracture of Engineering Materials & Structures, 2015

Abstract The objective of this work is to investigate the correlation between rim and web thickness on the crack propagation path in thin‐rimmed gears, referring to bending failures. To this aim, numerical simulations have been performed, based on the 3D extended finite element method. Results ...


Occurrence and distribution of glycerol dialkanol diethers and glycerol dialkyl glycerol tetraethers in a peat core from SW Tanzania

13-Apr-2015 | Author(s): Sarah Coffinet , Arnaud Huguet , David Williamson , Laurent Bergonzini , Christelle Anquetil , Amos ..., Organic Geochemistry, 2015

Theoretical study of tautomeric equilibria of 2,6-diamino-8-azapurine and 8-aza-iso-Guanine

12-Apr-2015 | Author(s): Maciej Pyrka , Maciej Maciejczyk, Chemical Physics Letters, 2015

Publication date: 1 May 2015 Source:Chemical Physics Letters, Volume 627 Author(s): Maciej Pyrka , Maciej Maciejczyk Tautomeric equilibria of amino forms of 2,6-diamino-8-azapurine and 8-aza-iso-Guanine is revealed by DFT computations. The most populated tautomer of ...


Structure and magnetism of novel dinuclear cobalt(II) complexes

12-Apr-2015 | Author(s): Jakub Mihalčiak , Petra Bertová , Zdeňka Růžičková , Ján Moncol , Peter Segľa , Roman Boča, Inorganic Chemistry Communications, 2015

Publication date: June 2015 Source:Inorganic Chemistry Communications, Volume 56 Author(s): Jakub Mihalčiak , Petra Bertová , Zdeňka Růžičková , Ján Moncol , Peter Segľa , Roman Boča Two dinuclear cobalt(II) complexes of the formula [Co2X4(isonia)4] have been synthesized and ...


IJMS, Vol. 16, Pages 7944-7959: Psoralea glandulosa as a Potential Source of Anticancer Agents for Melanoma Treatment

09-Apr-2015 | Madrid, Alejandro ; Cardile, Venera ; González, César ; Montenegro, Ivan ; Villena, Joan ; Caggia, Silvia ; Graziano ..., International Journal of Molecular Sciences, 2015

With the aim of identifying novel agents with antigrowth and pro-apoptotic activity on melanoma cancer, the present study was undertaken to investigate the biological activity of the resinous exudate of aerial parts from Psoralea glandulosa, and its active components (bakuchiol (1), ...


Crystallization and preliminary X‐ray analysis of four cysteine proteases from Ficus carica latex

07-Apr-2015 | Sarah Haesaerts, John Alexander Rodriguez Buitrago, Remy Loris, Danielle Baeyens‐Volant, Mohamed Azarkan, Acta Crystallographica Section F, 2015

The latex of the common fig (Ficus carica) contains a mixture of at least five cysteine proteases commonly known as ficins (EC Four of these proteases were purified to homogeneity and crystals were obtained in a variety of conditions. The four ficin (iso)forms appear in ten different ...


Glass-Like Slow Dynamics in a Colloidal Solid with Multiple Ground States

03-Apr-2015 | Chandana Mondal; Smarajit Karmakar; Surajit Sengupta, Journal of Physical Chemistry B, 2015

We study the phase-ordering dynamics of a 2D model colloidal solid using molecular dynamics simulations. The colloid particles interact with each other with a Hamaker potential modified by the presence of equatorial “patches” of attractive and repulsive regions. The total interaction potential ...


Preparation of Bis‐GMA‐Free Dental Restorative Composites with Dendritic Macromer (G‐IEMA)

31-Mar-2015 | Biao Yu, Fang Liu, Jingwei He, Yingcong He, Zhengmei Lin, Advances in Polymer Technology, 2015

ABSTRACT To reduce human exposure risk to bisphenol A derivatives, a new 2,2‐bis[p‐(2’‐hydroxy‐3’‐methacryloxypropoxy) phenylene]propane (Bis‐GMA) free dental composites material GEC‐66% was prepared using a dendritic macromer (G‐IEMA) as one component of resin matrix. Properties of GEC‐66%, ...
