Layer potential methods for elliptic homogenization problems
Authors: Kenig Carlos , Shen Zhongwei
Published: August 2010

In this paper we use the method of layer potentials to study L2 boundary value problems in a bounded Lipschitz domain Ω for a family of second‐order elliptic systems with rapidly oscillating periodic coefficients. Defining
${\cal L}_\varepsilon = - {\rm div}(A(\varepsilon ^{ - 1} X)\nabla )$, under the assumption that A(X) is elliptic, symmetric, periodic, and Hölder‐continuous, we establish the solvability of the L2 Dirichlet, regularity, and Neumann problems for ${\cal L}_\varepsilon (u_\varepsilon ) = 0$
in Ω with optimal estimates uniform in ε > 0. © 2010 Wiley Periodicals, Inc.
The micromechanics of three‐dimensional collagen‐I gels
Authors: Stein Andrew M. , Vader David A. , Weitz David A. , Sander Leonard M.
Published: August 2010

We study the micromechanics of collagen‐I gel with the goal of bridging the gap between theory and experiment in the study of biopolymer networks. Three‐dimensional images of fluorescently labeled collagen are obtained by confocal microscopy, and the network geometry is extracted using a 3D network skeletonization algorithm. Each fiber is modeled as an elastic beam that resists stretching and bending, and each crosslink is modeled as torsional spring. The stress–strain curves of networks at three different densities are compared with rheology measurements. The model shows good agreement with experiment, confirming that strain stiffening of collagen can be explained entirely by geometric realignment of the network, as opposed to entropic stiffening of individual fibers. The model also suggests that at small strains, crosslink deformation is the main contributer to network stiffness, whereas at large strains, fiber stretching dominates. As this modeling effort uses networks with realistic geometries, this analysis can ultimately serve as a tool for understanding how the mechanics of fibers and crosslinks at the microscopic level produce the macroscopic properties of the network. © 2010 Wiley Periodicals, Inc.

Spatial, temporal, and modulatory factors affecting the evolvability of GasNets — a style of artificial neural network incorporating an analogue of volume signalling — are investigated. The focus of the article is a comparative study of variants of the GasNet, implementing various spatial, temporal, and modulatory constraints, used as control systems in an evolutionary robotics task involving visual discrimination. The results of the study are discussed in the context of related research. © 2010Wiley Periodicals, Inc. Complexity 16: 35–44, 2010
Spatially embedded dynamics and complexity
Authors: Buckley Christopher L. , Bullock Seth , Barnett Lionel
Published: August 2010

To gain a deeper understanding of the impact of spatial embedding on the dynamics of complex systems, we use a measure of interaction complexity developed within neuroscience using the tools of statistical information theory. We apply this measure to a set of simple network models embedded within Euclidean spaces of varying dimensionality to characterize the way in which the constraints imposed by low‐dimensional spatial embedding contribute to the dynamics (rather than the structure) of complex systems. We demonstrate that strong spatial constraints encourage high intrinsic complexity and discuss the implications for complex systems in general. © 2010 Wiley Periodicals, Inc.

CO2 Adsorption on Supported Molecular Amidine Systems on Activated Carbon
Authors: Alesi W. Richard , Gray McMahan , Kitchin John R.
Published: August 2010

The CO2 capture capacities for typical flue gas capture and regeneration conditions of two tertiary amidine N‐methyltetrahydropyrimidine (MTHP) derivatives supported on activated carbon were determined through temperature‐controlled packed‐bed reactor experiments. Adsorption–desorption experiments were conducted at initial adsorption temperatures ranging from 29 °C to 50 °C with temperature‐programmed regeneration under an inert purge stream. In addition to the capture capacity of each amine, the efficiencies at which the amidines interact with CO2 were determined. Capture capacities were obtained for 1,5‐diazo‐bicyclo[4.3.0]non‐5‐ene (DBN) and 1,8‐diazobicyclo[5.4.0]‐undec‐7‐ene (DBU) supported on activated carbon at a loading of approximately 2.7 mol amidine per kg of sorbent. Moisture was found to be essential for CO2 capture on the amidines, but parasitic moisture sorption on the activated carbon ultimately limited the capture capacities. DBN was shown to have a higher capture capacity of 0.8 mol CO2 per kg of sorbent and an efficiency of 0.30 mol CO2 per mol of amidine at an adsorption temperature of 29 °C compared to DBU. The results of these experiments were then used in conjunction with a single‐site adsorption model to derive the Gibbs free energy for the capture reaction, which can provide information about the suitability of the sorbent under different operating conditions.
Can Metal–Organic Framework Materials Play a Useful Role in Large‐Scale Carbon Dioxide Separations?

Published: August 2010

Metal–organic frameworks (MOFs) are a fascinating class of crystalline nanoporous materials that can be synthesized with a diverse range of pore dimensions, topologies, and chemical functionality. As with other well‐known nanoporous materials, such as activated carbon and zeolites, MOFs have potential uses in a range of chemical separation applications because of the possibility of selective adsorption and diffusion of molecules in their pores. We review the current state of knowledge surrounding the possibility of using MOFs in large‐scale carbon dioxide separations. There are reasons to be optimistic that MOFs may make useful contributions to this important problem, but there are several critical issues for which only very limited information is available. By identifying these issues, we provide what we hope is a path forward to definitively answering the question posed in our title.

Published: August 2010

NaCaPO4:Ce3+,Tb3+ phosphors were prepared by a solid‐state reaction. Their luminescence properties reveal that an efficient energy transfer from the Ce3+ to Tb3+ ions occurs, and its mechanism is a resonant type by means of a dipole–quadrupole reaction. The critical distance of the energy transfer has been calculated by concentration‐quenching and spectral‐overlap methods. The varied emitted color of the phosphors from blue to yellow‐greenish can be achieved by properly tuning the relative ratio of Ce3+ and Tb3+ through the energy transfer from the Ce3+ to Tb3+ ions. These results indicate that NaCaPO4:Ce3+,Tb3+ is potentially useful as a highly efficient, green‐emitting, UV‐convertible phosphor for white‐light‐emitting diodes. Moreover, the accurate oscillator strength ratio of the electric quadrupole‐to‐dipole transitions for the Tb3+ ion was obtained to be about 10–3, which may be of much significance in the estimate of the critical distance of the dipole–quadrupole interaction between Ce3+ and Tb3+ ions through Dexter's energy‐transfer theory.

Tricarbonylrhenium(I) and ‐technetium(I) halide (halide = Cl and Br) complexes of ligands derived from 4,5‐diazafluoren‐9‐one (df) and 1,10‐phenanthroline‐5,6‐dione (phen) derivatives of benzoic and 2‐hydroxybenzoic acid hydrazides have been prepared. The complexes have been characterized by elemental analysis, MS, IR, 1H NMR and absorption and emission UV/Vis spectroscopic methods. The metal centres (ReI and TcI) are coordinated through the nitrogen imine atoms and establish five‐membered chelate rings, whereas the hydrazone groups stand uncoordinated. The 1H NMR spectra suggest the same behaviour in solution on the basis of only marginal variations in the chemical shifts of the hydrazine protons.

Published: August 2010

A general method for patterning various functional inorganic nanomaterials on SiOx/Si substrates by using microcontact printing (μCP) was developed. The application of hydrophobic poly(dimethylsiloxane) (PDMS) stamps is essential for the reproducibility of this process. By tuning the concentration of the nanoparticle solutions, we can control the thickness of the nanoparticle layers on surfaces. The patterned ZnO nanoparticles on surfaces are used as seeds to grow ZnO nanorod arrays, and the patterned Fe3O4 nanoparticles or Fe/Mo nanoclusters are used as catalysts for the patterned growth of carbon nanotube arrays. This shows that μCP is a facile method to pattern inorganic nanoparticles relying on PDMS stamps of designed surface affinity. Patterned 1Dnanomaterial arrays can subsequently be obtained by use of solution path seeded growth or catalyzed chemical vapor deposition.
Ditopic 8‐Hydroxyquinoline‐2‐carboxamides as Ligands for the Formation of Dinuclear Lanthanide(III) Helicates
Authors: Albrecht Markus , Osetska Olga
Published: August 2010

Ditopic ligands (1–4)‐H2 are easily obtained by coupling 8‐hydroxyquinoline‐2‐carboxylic acid with diamines. Dinuclear helicate‐type complexes [La2(L)3] (L = ligand) are easily obtained with alkyl‐bridged ligands 2 and 3. Short hydrazine as a linkage (1) seems to lead to polymerization, whereas with 4 only [Yb2(4)3] could be characterized by ESIMS. Comparison of the alkyl‐bridged derivatives reveals that, in the case of short spacers, alkali cations can be incorporated into the interior of the helicate, whereas this is not observed with the butyl‐bridged coordination compounds.

Nanoporous magnetic materials composed of metal‐assembled complexes are expected to exhibit chemical sensitivity. In this work, we observed a humidity‐induced reversible change between ferromagnetism and antiferromagnetism in a new type of a cobalt octacyanoniobate based magnet in the high‐humidity region. This humidity response is caused by the adsorption and desorption of non‐coordinated water (so‐called zeolitic water) molecules in the interstitial site. Such a phenomenon is achieved by the structural flexibility of an octacyanometalate‐based magnet.

We herein present the first synthesis of 1,1′‐binaphthyl‐2,2′‐bis(sulfuryl)imides (JINGLEs). This new class of chiral Brønsted acids was synthesized in one step from the corresponding BINOLs and imidobis(sulfuryl chloride). A total of six enantiopure 1,1′‐binaphthyl‐2,2′‐bis(sulfuryl)imides, carrying different 3,3′‐substituents, were synthesized and characterized, inter alia, by X‐ray crystallography.
Cosmetic Electrochemistry II: Rapid and Facile Production of Metallic Electrocatalytic Ensembles

Published: August 2010

We demonstrate a facile methodology for the production of metallic electrocatalytic microdomain ensembles for a range of analytical sensing challenges. A commercially available off‐the‐shelf cosmetic product can change the voltammetric characteristics of a metallic macro‐electrode created electrolytically into that of a random ensemble of metallic microelectrode domains. Proof‐of‐concept is shown for three examples: a palladium ensemble for hydrazine sensing, a gold ensemble for arsenic(III) detection via anodic stripping voltammetry and platinum ensembles for the direct oxidation of arsenic(III). Last we demonstrate that the fabrication of metallic microdomains can be simplified by sputter coating screen printed electrochemical sensing platforms which are beneficially constructed using this cosmetic methodology. Given the facile fabrication and low cost of the underlying electrode substrate and the cosmetic modifier, the widespread implementation of this novel fabrication methodology is expected.

Electrodeposited and sprayed Pt anode catalysts were electrochemically characterised by CO stripping voltammetry as well as their activity to CO tolerance in micro‐PEMFCs was demonstrated using polarisation measurements. While the onset and peak potentials of CO oxidation on the sprayed Pt/C varied with the CO coverage, these were lower (∼50 mV) with the electrodeposited Pt anode. This difference is attributed to the varying properties of the Pt–OH on either rough or smooth surface mainly created from different sizes of Pt particles. In fuel cell performance test, the electrodeposited Pt anode showed maximum power density of 360 mW cm–2 and it was markedly (∼110 mW cm–2) higher than the sprayed Pt/C anode. The enhanced activity of the electrodeposited Pt anode is also reflected by the fact that the entire amount of adsorbed CO becomes almost desorbed during the first three polarisation scans, while with the Pt/C anode at least five cycles are required.

Membranes based on poly[2,2′‐(p‐oxydiphenylene)‐5,5′‐bibenzimidazole] (OPBI) and their sulphonated derivatives (SOPBI) were prepared and first investigated for high temperature proton exchange membrane fuel cells. OPBI and SOPBI membranes with good chemical stability were prepared by casting from their dimethyl sulphoxide (DMSO) solution and then impregnated in phosphoric acid baths to obtain H3PO4 (PA)‐doped membranes. The properties of PA‐doped OPBI membranes, including phosphoric acid uptake, swelling ratio, mechanical properties and thermal properties, were fully investigated and compared with PA‐doped SOPBI membranes. The fuel cell performances of PA‐doped OPBI and SOPBI membranes at different temperatures were first evaluated. When doped in different concentrations of H3PO4 solution, OPBI membranes adsorb more acid than SOPBI membranes. SOPBI membranes exhibit obviously lower swelling ratio in thickness direction than that of OPBI membranes. With an acid uptake of ∼110 wt.‐%, corresponding doping level around 5, PA‐doped OPBI and SOPBI membranes keep reasonably high tensile strength. PA‐doped OPBI membranes exhibit peak power density of 0.78 W cm–2 at 170 °C and 0.25 MPa. With the same acid uptake, PA‐doped SOPBI membranes displayed similar fuel cell performance to that of PA‐doped OPBI membranes.

Published: August 2010

Dense and thin electrolyte films are desirable for solid oxide fuel cells (SOFCs) because of their low gas leakage and low ohmic resistances. This work aims at the preparation of thin dense Gd‐doped ceria (CGO) electrolyte films using a cost‐effective deposition method in ambient atmosphere–electrostatic spray deposition (ESD). The deposition parameters such as deposition temperature, concentration and flow rate of precursor solution were changed systematically to examine their effects on film morphology and hence electrochemical performance. While the film morphology was examined by a scanning electron microscope, the electrochemical performance was revealed by measuring open circuit voltages (OCVs) of NiO‐CGO/CGO/Ba0.5Sr0.5Co0.8Fe0.2O3‐δ (BSCF) cells in 500–700 °C with humidified hydrogen as fuel and air as oxidant. The results show that a CGO film of 25 μm thick obtained at a deposition temperature of 400 °C, a precursor solution flow rate of 6 ml h–1 and a precursor concentration of 0.3 M was dense with very few isolated pores and the OCV of the associated cell was 0.915 V at 500 °C. This implies that the CGO film has negligible gas leakage and ESD is a promising method for preparing thin dense electrolyte films for SOFCs.
Low‐Temperature Preparation of La0.6Sr0.4Fe0.8Co0.2O3–δ Sinterable Nanopowders by the Polymeric Organic Complex Solution Method
Authors: Perez‐Falcon J. M. , Moure A. , Tartaj J.
Published: August 2010

In this work, powders of La0.6Sr0.4Fe0.8Co0.2O3–δ were prepared by the auto‐combustion of ethylene glycol–metal nitrate polymerised gel precursor. This method (polymeric organic complex solution) allows decreasing the processing temperature and simplifies the whole procedure. A single phase material is obtained at 300 °C lower than that needed by conventional solid state reaction (SSR). The reduced particle size and low agglomeration increases the reactivity of powders and therefore, the sintering temperature is also reduced in 200 °C with respect to the conventional SSR method. As a consequence of that, the microstructures are controlled maintaining the grain size in an almost nanometric range.
