Structural Transformation and Tuning Behavior Induced by Propylamine Concentration in Hydrogen Clathrate Hydrates

25-11-2014 | Seongmin Park; Hyery Kang; Kyuchul Shin; Yutaek Seo; Huen Lee, Physical Chemistry Chemical Physics, 2014

The structures and the guest-host distributions of iso-propylamine (i-PA) and n-propylamine (n-PA) hydrates with hydrogen as a secondary guest were identified by the powder X-ray diffraction and the Raman spectroscopic analysis. The structure of the i-PA 11.1 mol% + H2 hydrate was identified to ...

Dose‐dependent effects of isoflavone exposure during early lifetime on the rat mammary gland: Studies on estrogen sensitivity, isoflavone metabolism and DNA methylation

20-11-2014 | Tina Blei, Sebastian T. Soukup, Katja Schmalbach, Maria Pudenz, Frank Josef Möller, Björn Egert, Nadine Wörtz, Anne ..., Molecular Nutrition & Food Research, 2014

Scope : Isoflavone (ISO) exposure during adolescence modulates 17β‐estradiol (E2) sensitivity of the adult mammary gland. The present study investigated the dose‐dependency of these effects focusing on proliferation, estrogen receptor (ER)‐dependent and ‐independent gene expression, as well as ...

Influence of Selenocyanate Ligands on the Transition Temperature and Cooperativity of bapbpy-Based Fe(II) Spin-Crossover Compounds

20-11-2014 | Sipeng Zheng; Maxime A. Siegler; Olivier Roubeau; Sylvestre Bonnet, Inorganic Chemistry, 2014

Coordination of the ligand bapbpy (1, bapbpy = N,N′-di(pyrid-2-yl)-2,2′-bipyridine-6,6′-diamine), of one of its four dimethyl-substituted analogues 2–5 (R2bapbpy = N,N′-di(methylpyrid-2-yl)-2,2′-bipyridine-6,6′-diamine), or of one of its three bis(iso)quinoline analogues 6–8 (R2bapbpy= ...

Effect of Methyl-Branched Fatty Acids on the Structure of Lipid Bilayers

19-11-2014 | David Poger; Bertrand Caron; Alan E. Mark, Journal of Physical Chemistry B, 2014

Methyl-branched fatty acids are widespread in prokaryotic membranes. Although anteiso and iso branching (that is on the antepenultimate and penultimate carbons) and the presence of multiple methyl branches in the phytanoyl chain are known to modify the thermotropic behavior and enhance the ...

Excitonic Splitting, Delocalization, and Vibronic Quenching in the Benzonitrile Dimer

17-11-2014 | Franziska A. Balmer; Philipp Ottiger; Samuel Leutwyler, Journal of Physical Chemistry A, 2014

The excitonic S1/S2 state splitting and the localization/delocalization of the S1 and S2 electronic states are investigated in the benzonitrile dimer (BN)2 and its 13C and d5 isotopomers by mass-resolved two-color resonant two-photon ionization spectroscopy in a supersonic jet, complemented by ...

Burst Strength of Tubing and Casing Based on Twin Shear Unified Strength Theory

14-11-2014 | Yuanhua Lin et al., PLoS ONE, 2014

by Yuanhua Lin, Kuanhai Deng, Yongxing Sun, Dezhi Zeng, Wanying Liu, Xiangwei Kong, Ambrish Singh The internal pressure strength of tubing and casing often cannot satisfy the design requirements in high pressure, high temperature and high H2S gas wells. Also, the practical safety coefficient of ...

Combustion properties of Brazilian natural wood species

13-11-2014 | Monique Amaro Rocha, Alexandre Landesmann, Fire and Materials, 2014

SUMMARY This paper investigates the combustion characteristics of 12 wood species natural to Brazil. A mass loss cone calorimeter was used to obtain the properties associated with (i) heat release rate (HRR), peak HRR, and total heat released; (ii) total mass loss and mass loss rate; (iii) ...

Isotope ratio analysis of carbon and nitrogen by elemental analyser continuous flow isotope ratio mass spectrometry (EA-CF-IRMS) without the use of a reference gas

12-11-2014 | L. J. Bay; S. H. Chan; T. Walczyk, Journal of Analytical Atomic Spectrometry, 2014

A new approach to normalize measured isotope ratios (carbon and nitrogen) by elemental analyser continuous flow isotope ratio mass spectrometry (EA-CF-IRMS) was evaluated. Isotope ratios of samples are altered during the IRMS measurement and must be corrected for both instrumental drifts as well ...
