Real-Time UV-Visible Spectroscopy Analysis of Purple Membrane-Polyacrylamide Film Formation Taking into Account Fano Line Shapes and Scattering

17-10-2014 | María Gomariz et al., PLoS ONE, 2014

by María Gomariz, Salvador Blaya, Pablo Acebal, Luis Carretero We theoretically and experimentally analyze the formation of thick Purple Membrane (PM) polyacrylamide (PA) films by means of optical spectroscopy by considering the absorption of bacteriorhodopsin and scattering. We have applied ...

Energies, Vol. 7, Pages 6401-6411: Experimental Investigation and Discussion on the Mechanical Endurance Limit of Nafion Membrane Used in Proton Exchange Membrane Fuel Cell

09-10-2014 | Xiao, Yang ; Cho, Chongdu, Energies, 2014

As a solution of high efficiency and clean energy, fuel cell technologies, especially proton exchange membrane fuel cell (PEMFC), have caught extensive attention. However, after decades of development, the performances of PEMFCs are far from achieving the target from the Department of Energy ...

Energies, Vol. 7, Pages 6340-6357: New Power Quality Analysis Method Based on Chaos Synchronization and Extension Neural Network

08-10-2014 | Wang, Meng-Hui ; Yau, Her-Terng, Energies, 2014

A hybrid method comprising a chaos synchronization (CS)-based detection scheme and an Extension Neural Network (ENN) classification algorithm is proposed for power quality monitoring and analysis. The new method can detect minor changes in signals of the power systems. Likewise, prominent ...

A cellular solution to an information-processing problem [Applied Physical Sciences]

26-08-2014 | Garud Iyengar; Madan Rao, Proceedings of the National Academy of Sciences current issue, 2014

Signaling receptors on the cell surface are mobile and have evolved to efficiently sense and process mechanical or chemical information. We pose the problem of identifying the optimal strategy for placing a collection of distributed and mobile sensors to faithfully estimate a signal that varies ...

Structure of {beta}-galactosidase at 3.2-A resolution obtained by cryo-electron microscopy [Biophysics and Computational Biology]

12-08-2014 | Alberto Bartesaghi; Doreen Matthies; Soojay Banerjee; Alan Merk; Sriram Subramaniam, Proceedings of the National Academy of Sciences current issue, 2014

We report the solution structure of Escherichia coli β-galactosidase (∼465 kDa), solved at ∼3.2-Å resolution by using single-particle cryo-electron microscopy (cryo-EM). Densities for most side chains, including those of residues in the active site, and a catalytic Mg2+ ion can be discerned in ...

The magnetoelectrochemical switch [Applied Physical Sciences]

22-07-2014 | Petru Lunca Popa; Neil T. Kemp; Hicham Majjad; Guillaume Dalmas; Vina Faramarzi; Christian Andreas; Riccardo Hertel; ..., Proceedings of the National Academy of Sciences current issue, 2014

In the field of spintronics, the archetype solid-state two-terminal device is the spin valve, where the resistance is controlled by the magnetization configuration. We show here how this concept of spin-dependent switch can be extended to magnetic electrodes in solution, by magnetic control of ...

Energies, Vol. 6, Pages 4830-4840: Electrostatic Self-Assembly of Fe3O4 Nanoparticles on Graphene Oxides for High Capacity Lithium-Ion Battery Anodes

12-09-2013 | Yoon, Taegyune ; Kim, Jaegyeong ; Kim, Jinku ; Lee, Jung Kyoo, Energies, 2013

Magnetite, Fe3O4, is a promising anode material for lithium ion batteries due to its high theoretical capacity (924 mA h g−1), high density, low cost and low toxicity. However, its application as high capacity anodes is still hampered by poor cycling performance. To stabilize the cycling ...
