Excluded‐Volume Effects in Living Cells

29-Dec-2014 | David Gnutt, Mimi Gao, Oliver Brylski, Matthias Heyden, Simon Ebbinghaus, Angewandte Chemie International Edition, 2014

Abstract Biomolecules evolve and function in densely crowded and highly heterogeneous cellular environments. Such conditions are often mimicked in the test tube by the addition of artificial macromolecular crowding agents. Still, it is unclear if such cosolutes indeed reflect the ...

Impact of nanoclay on physicomechanical and thermal analysis of polyvinyl alcohol/fumed silica/clay nanocomposites

26-Dec-2014 | Josephine Chang‐Hui Lai, Md. Rezaur Rahman, Sinin Hamdan, Fui Kiew Liew, Md. Mizanur Rahman, Md. Faruk Hossen, Journal of Applied Polymer Science, 2014

ABSTRACT Polyvinyl alcohol (PVA)/fumed silica/clay nanocomposites are prepared via solution intercalation by exploiting phase separation based on the bridging of particles by polymer chains. PVA/fumed silica/clay nanocomposites are characterized by Fourier transform infrared spectroscopy ...

Upgrade of MacCHESS facility for X‐ray scattering of biological macromolecules in solution

26-Dec-2014 | Alvin Samuel Acerbo, Michael J. Cook, Richard Edward Gillilan, Journal of Synchrotron Radiation, 2014

X‐ray scattering of biological macromolecules in solution is an increasingly popular tool for structural biology and benefits greatly from modern high‐brightness synchrotron sources. The upgraded MacCHESS BioSAXS station is now located at the 49‐pole wiggler beamline G1. The 20‐fold improved ...

Energies, Vol. 8, Pages 154-171: A Novel Constant-Pressure Pumped Hydro Combined with Compressed Air Energy Storage System

26-Dec-2014 | Yao, Erren ; Wang, Huanran ; Liu, Long ; Xi, Guang, Energies, 2014

As intermittent renewable energy is receiving increasing attention, the combination of intermittent renewable energy with large-scale energy storage technology is considered as an important technological approach for the wider application of wind power and solar energy. Pumped hydro combined with ...

Effect of synthesis temperature on characteristics of PNIPAM/alginate IPN hydrogel beads

24-Dec-2014 | Masanori Ochi, Junichi Ida, Tatsushi Matsuyama, Hideo Yamamoto, Journal of Applied Polymer Science, 2014

ABSTRACT Poly(N‐isopropylacrylamide)/alginate interpenetrating polymer network hydrogel beads (IPN beads) were prepared via modified inverse emulsion polymerization, and the effect of the synthesis temperature on the characteristics of the IPN beads was investigated. Varying the synthesis ...

Self-enhanced electrogenerated chemiluminescence of ruthenium(II) complexes conjugated with Schiff bases

24-Dec-2014 | Panpan Li; Zhaoyu Jin; Meilian Zhao; Yanxue Xu; Yong Guo; Dan Xiao, Dalton Transactions, 2014

In this work, we obtain two ruthenium(ii) complexes with Schiff base cavities that exhibit significantly enhanced electrochemiluminescence (ECL) intensity and quantum efficiency due to Ru(bpy)32+ in aqueous solution, without the addition of tri-n-propylamine (TPrA). The great increase in ECL ...

Proton, muon and 13C hyperfine coupling constants of C60X and C70X (X = H, Mu)

24-Dec-2014 | Jean-Claude Brodovitch; Brenda Addison-Jones; Khashayar Ghandi; Iain McKenzie; Paul W. Percival, Physical Chemistry Chemical Physics, 2014

The reaction of H atoms with fullerene C70 has been investigated by identifying the radical products formed by addition of the atom muonium (Mu) to the fullerene in solution. Four of the five possible radical isomers of C70Mu were detected by avoided level-crossing resonance (μLCR) spectroscopy, ...

Pendant Alkyl and Aryl Groups on Tin Control Complex Geometry and Reactivity with H2/D2 in Pt(SnR3)2(CNBut)2 (R = But, Pri, Ph, Mesityl)

24-Dec-2014 | Anjaneyulu Koppaka; Lei Zhu; Veeranna Yempally; Derek Isrow; Perry J. Pellechia; Burjor Captain, Journal of the American Chemical Society, 2014

The complex Pt(SnBut3)2(CNBut)2(H)2, 1, was obtained from the reaction of Pt(COD)2 and But3SnH, followed by addition of CNBut. The two hydride ligands in 1 can be eliminated, both in solution and in the solid state, to yield Pt(SnBut3)2(CNBut)2, 2. Addition of hydrogen to 2 at room temperature in ...

Solvation and Hydration of the Ceramide Headgroup in a Non-Polar Solution

24-Dec-2014 | Richard J. Gillams; Jon V. Busto; Sebastian Busch; Félix M. Goñi; Christian D. Lorenz; Sylvia E. McLain, Journal of Physical Chemistry B, 2014

The microscopic hydration of the ceramide headgroup has been determined using a combination of experimental—both NMR and neutron diffraction techniques and computational techniques—empirical potential structure refinement (EPSR) and molecular dynamics (MD). The addition of water to ceramide in ...
