Al-doped MgB2 materials studied using electron paramagnetic resonance and Raman spectroscopy
2016 APPLIED PHYSICS LETTERS, Band: 108, Nummer: 20
KurzfassungUndoped and aluminum (Al) doped magnesium diboride (MgB2) samples were synthesized using a high-temperature solid-state synthesis method. The microscopic defect structures of Al-doped MgB2 samples were systematically investigated using X-ray powder diffraction, Raman spectroscopy, and electron paramagnetic resonance. It was found that Mg-vacancies are responsible for defect-induced peculiarities in MgB2. Above a certain level of Al doping, enhanced conductive properties of MgB2 disappear due to filling of vacancies or trapping of Al in Mg-related vacancy sites. Published by AIP Publishing.

Can mosses serve as model organisms for forest research?
2016 ANNALS OF FOREST SCIENCE, Band: 73, Nummer: 1, Seiten: 135 - 146
KurzfassungContext and aims Mosses are important components of several ecosystems. The moss P. patens is a well-established non-vascular model plant with a high amenability to molecular biology techniques and was designated as a JGI plant flagship genome. In this review, we will provide an introduction to moss research and highlight the characteristics of P. patens and other mosses as a potential complementary model system for forest research. Methods Starting with an introduction into general moss biology, we summarize the knowledge about moss physiology and differences to seed plants. We provide an overview of the current research areas utilizing mosses, pinpointing potential links to tree biology. To complement literature review, we discuss moss advantages and available resources regarding molecular biology techniques. Results and conclusion During the last decade, many fundamental processes and cell mechanisms have been studied in mosses and seed plants, increasing our knowledge of plant evolution. Additionally, moss-specific mechanisms of stress tolerance are under investigation to understand their resilience in ecosystems. Thus, using the advantages of model mosses such as P. patens is of high interest for various research approaches, including stress tolerance, organelle biology, cell polarity, and secondary metabolism.

Constructing higher order DNA origami arrays using DNA junctions of anti-parallel/parallel double crossovers
2016 JAPANESE JOURNAL OF APPLIED PHYSICS, Band: 55, Nummer: 6, 1
KurzfassungDNA origami provides a versatile method for the construction of nanostructures with defined shape, size and other properties; such nanostructures may enable a hierarchical assembly of large scale architecture for the placement of other nanomaterials with atomic precision. However, the effective use of these higher order structures as functional components depends on knowledge of their assembly behavior and mechanical properties. This paper demonstrates construction of higher order DNA origami arrays with controlled orientations based on the formation of two types of DNA junctions: anti-parallel and parallel double crossovers. A two-step assembly process, in which preformed rectangular DNA origami monomer structures themselves undergo further self-assembly to form numerically unlimited arrays, was investigated to reveal the influences of assembly parameters. AFM observations showed that when parallel double crossover DNA junctions are used, the assembly of DNA origami arrays occurs with fewer monomers than for structures formed using anti-parallel double crossovers, given the same assembly parameters, indicating that the configuration of parallel double crossovers is not energetically preferred. However, the direct measurement by AFM force-controlled mapping shows that both DNA junctions of anti-parallel and parallel double crossovers have homogeneous mechanical stability with any part of DNA origami.

Dissipative particle dynamics of diffusion-NMR requires high Schmidt-numbers
2016 JOURNAL OF CHEMICAL PHYSICS, Band: 144, Nummer: 24
KurzfassungWe present an efficient mesoscale model to simulate the diffusion measurement with nuclear magnetic resonance (NMR). On the level of mesoscopic thermal motion of fluid particles, we couple the Bloch equations with dissipative particle dynamics (DPD). Thereby we establish a physically consistent scaling relation between the diffusion constant measured for DPD-particles and the diffusion constant of a real fluid. The latter is based on a splitting into a centre-of-mass contribution represented by DPD, and an internal contribution which is not resolved in the DPD-level of description. As a consequence, simulating the centre-of-mass contribution with DPD requires high Schmidt numbers. After a verification for fundamental pulse sequences, we apply the NMR-DPD method to NMR diffusion measurements of anisotropic fluids, and of fluids restricted by walls of microfluidic channels. For the latter, the free diffusion and the localisation regime are considered. Published by AIP Publishing.

Dynamical Casimir-Polder interaction between a chiral molecule and a surface
2016 PHYSICAL REVIEW A, Band: 93, Nummer: 3
KurzfassungWe develop a dynamical approach to study the Casimir-Polder force between an initially bare molecule and a magnetodielectric body at finite temperature, valid for arbitrary magnetodielectric properties and also in the presence of chiral effects. Switching on the interaction between the molecule and the field at a particular time, we study the resulting temporal evolution of the Casimir-Polder interaction. The dynamical self-dressing of the molecule and its population-induced dynamics are accounted for and discussed. In particular, we find that the Casimir-Polder force between a molecule and a surface oscillates in time with a frequency related to the molecular transition frequency. We verify that the dynamical force converges to the static result for time much larger than the inverse of the transition frequency, and it is particularly strong around the back-reaction time t = 2d/c, the time needed for the molecule to emit and reabsorb a photon reflected by the surface.

Effect of homogenization (microfluidization) process parameters in mechanical production of micro- and nanofibrillated cellulose on its rheological and morphological properties
2016 CELLULOSE, Band: 23, Nummer: 2, Seiten: 1221 - 1238
KurzfassungThe rheological properties of microfibrillated cellulose (MFC)/nanofibrillated cellulose (NFC) suspensions have an important role during processing and mixing. In this work, the process parameters for MFC/NFC production within a microfluidizer (i.e., the size of interaction chamber and number of passes) were varied to investigate the influences on morphology, zeta potential, chemical properties and rheological features including viscosity, creep, strain recovery and yield stress behavior. The stability and appropriate viscosity of the fiber suspensions can be controlled by optimizing the processing conditions, resulting in a reduction in fiber diameter and most negative zeta potential value. The viscosity increased with higher amount of fibrillation by using a smaller chamber or higher number of passes, but intermediate plateau values are characteristic for temporary aggregation and breaking-up of the fiber network. The creep response and yield stress have been described by parameters of the Burger model and Herschel-Bulkley model, respectively, showing a more prominent effect on yield stress of chamber size than number of passes. The network formation leads to lower creep compliance and step-like strain recovery. The transition from gel-like to liquid-like behavior as characterized by the dynamic yield point at a specific strain, is almost independent of the processing conditions. Most important, the total number of passes applied in production can be directly related to the rotational P,clet number, which combines rheological and morphological data.

Effects of van der Waals forces and salt ions on the growth of water films on ice and the detachment of CO2 bubbles
2016 EPL, Band: 113, Nummer: 4
KurzfassungWe study the effect of salts on the thickness of wetting films on melting ice and interactions acting on CO2 bubble near ice-water and vapor-water interfaces. Governing mechanisms are the Lifshitz and the double-layer interactions in the respective three-layer geometries. We demonstrate that the latter depend on the Casimir-Polder interaction of the salt ions dissolved in water with the respective ice, vapor and CO2 interfaces, as calculated using different models for their effective polarizability in water. Significant variation in the predicted thickness of the equilibrium water film is observed for different salt ions and when using different models for the ions’ polarizabilities. We find that CO2 bubbles are attracted towards the ice-water interface and repelled from the vapor-water interface. Copyright (C) EPLA, 2016

Electron Transfer Pathways in a Tetrathiafulvalene-Aluminum(III) Porphyrin-Free-Base Porphyrin Triad Studied Using Electron Spin Polarization
2016 APPLIED MAGNETIC RESONANCE, Band: 47, Nummer: 5, Seiten: 511 - 526
KurzfassungThe electron transfer pathways in two axially bound triads based on aluminum(III) porphyrin (AlPor) are investigated using the electron spin polarization patterns of the final radical pair state. In the triads, TTF-(Ph)(n)-py-AlPor-Ph-H(2)Por (n = 0, 1), free-base porphyrin (H(2)Por) is attached covalently to the Al(III) center, while the donor tetrathiafulvalene (TTF) coordinates to Al(III) via an appended pyridine on the opposite face of the porphyrin ring. Excitation of the triad at 532 nm leads to absorption by both AlPor and H(2)Por and to two possible charge separation pathways. In the liquid crystalline solvent 5CB, spin polarized transient electron paramagnetic resonance spectra of a weakly coupled radical pair are observed and assigned to the state . The radical pair spectra are analyzed using a structural model of the complex to determine the dipolar coupling and relative orientation of the radicals. The inertia tensor calculated from the structural model is used to derive the principal values and axes of the order matrix. It is shown that the observed polarization pattern is only consistent with ferromagnetic exchange coupling in the radical pair. The spectra can be reproduced as the sum of two contributions originating in electron transfer from the excited singlet state of AlPor and from the excited the triplet state of H(2)Por. The latter is shown to account for the integral emissive net polarization observed in the spectra.

Event-driven Monte Carlo: Exact dynamics at all time scales for discrete-variable models
2016 EPL, Band: 114, Nummer: 5
KurzfassungWe present an algorithm for the simulation of the exact real-time dynamics of classical many-body systems with discrete energy levels. In the same spirit of kinetic Monte Carlo methods, a stochastic solution of the master equation is found, with no need to define any other phase-space construction. However, unlike existing methods, the present algorithm does not assume any particular statistical distribution to perform moves or to advance the time, and thus is a unique tool for the numerical exploration of fast and ultra-fast dynamical regimes. By decomposing the problem in a set of two-level subsystems, we find a natural variable step size, that is well defined from the normalization condition of the transition probabilities between the levels. We successfully test the algorithm with known exact solutions for non-equilibrium dynamics and equilibrium thermodynamical properties of Ising-spin models in one and two dimensions, and compare to standard implementations of kinetic Monte Carlo methods. The present algorithm is directly applicable to the study of the real-time dynamics of a large class of classical Markovian chains, and particularly to short-time situations where the exact evolution is relevant.

Hydrolases of the ILR1-like family of Arabidopsis thaliana modulate auxin response by regulating auxin homeostasis in the endoplasmic reticulum
2016 SCIENTIFIC REPORTS, Band: 6
KurzfassungAmide-linked conjugates of indole-3-acetic acid (IAA) have been identified in most plant species. They function in storage, inactivation or inhibition of the growth regulator auxin. We investigated how the major known endogenous amide-linked IAA conjugates with auxin-like activity act in auxin signaling and what role ILR1-like proteins play in this process in Arabidopsis. We used a genetically encoded auxin sensor to show that IAA-Leu, IAA-Ala and IAA-Phe act through the TIR1-dependent signaling pathway. Furthermore, by using the sensor as a free IAA reporter, we followed conjugate hydrolysis mediated by ILR1, ILL2 and IAR3 in plant cells and correlated the activity of the hydrolases with a modulation of auxin response. The conjugate preferences that we observed are in agreement with available in vitro data for ILR1. Moreover, we identified IAA-Leu as an additional substrate for IAR3 and showed that ILL2 has a more moderate kinetic performance than observed in vitro. Finally, we proved that IAR3, ILL2 and ILR1 reside in the endoplasmic reticulum, indicating that in this compartment the hydrolases regulate the rates of amido-IAA hydrolysis which results in activation of auxin signaling.

Impact of anisotropy on the interaction of an atom with a one-dimensional nano-grating
2016 INTERNATIONAL JOURNAL OF MODERN PHYSICS A, Band: 31, Nummer: 2-3, SI
KurzfassungWe study the interaction of an atom with a one-dimensional nano-grating within the framework of macroscopic QED, with special emphasis on possible anisotropic contributions. To this end, we first derive the scattering Green’s tensor of the grating by means of a Rayleigh expansion and discuss its symmetry properties and asymptotes. We then determine the Casimir-Polder potential of an atom with the grating. In particular, we find that strong anisotropy can lead to a repulsive Casimir-Polder potential in the normal direction.

Macro and nano scale modelling of water-water interactions at ambient and low temperature: relaxation and residence times
2016 PHYSICAL CHEMISTRY CHEMICAL PHYSICS, Band: 18, Nummer: 14, Seiten: 9377 - 9387
KurzfassungThe decay dynamics of ambient and low temperature liquid water has been investigated through all-atom molecular dynamics simulations, residence times calculations and time correlation functions from 300 K down to 243 K. Those simulations replicate the experimental value of the self-diffusion constant as a function of temperature by tuning the damping factor of the Langevin equation of motion. A stretched exponential function exp[-(t/tau)(beta)] has been found to properly describe the relaxation of residence times calculated at different temperatures for solvent molecules in a nanodrop of free water modelled as a sphere of nanometric dimensions. As the temperature goes down the decay time tau increases showing a divergence at T-s = 227 +/- 3 K. The temperature independence of the dimensionless stretched exponent beta = 0.59 +/- 0.01 suggests the presence of, not a characteristic relaxation time (since beta not equal 1), but a distribution of decay times that also holds at low temperature. An explanation for such heterogeneity can be found at the nanoscopic level. Moreover it can be concluded that the distribution of times already reported for the dynamics of water surrounding proteins (beta <= 0.5) can not be exclusively due to the presence of the biomolecule itself since isolated water also exhibits such behaviour. The above reported Ts and b values quantitatively reproduce experimental data.

Quantum Transport on Disordered and Noisy Networks: An Interplay of Structural Complexity and Uncertainty
2016 ANNUAL REVIEW OF CONDENSED MATTER PHYSICS, VOL 7, Band: 7, Seiten: 223 - 248
KurzfassungWe discuss recent research on quantum transport in complex materials, from photosynthetic light-harvesting complexes to photonic circuits. We identify finite, disordered networks as the underlying backbone and as a versatile framework to gain insight into the specific potential of nontrivial quantum dynamical effects to characterize and control transport on complex structures. We discriminate authentic quantum properties from classical aspects of complexity and briefly address the impact of interactions, nonlinearities, and noise. We stress the relevance of what we call the nonasymptotic realm, physical situations in which neither the relevant time-and length-scales, the number of degrees of freedom, or constituents tend to very small or very large values, nor do global symmetries or disorder fully govern the dynamics. Although largely uncharted territory, we argue that novel, intriguing and nontrivial questions for experimental and theoretical work emerge, with the prospect of a unified understanding of complex quantum transport phenomena in diverse physical settings.

Rheological behaviour of oil-filled polymer nanoparticles in aqueous dispersion
2016 COLLOIDS AND SURFACES A-PHYSICOCHEMICAL AND ENGINEERING ASPECTS, Band: 499, Seiten: 31 - 45
KurzfassungHybrid organic nanoparticles of poly(styrene-co-maleimide) with 70 wt.-% incorporated palm oil (SMI/oil) were provided in aqueous dispersion for use in industrial coating processes. The rheological characteristics of dispersions with 65 wt.-% and 35 wt.-% solid content have been determined by creep, oscillatory and rotational testing under different shear stresses, shear rates, frequencies and temperatures. The effects of oil on viscoelastic properties have been demonstrated by comparative tests on a 35 wt.-% pure SMI nanoparticle dispersion. The creep and strain recovery data show viscoelastic responses only for 65 wt.-% SMI/oil dispersions at low stresses, as further detailed by the calculated Burger model parameters. The 65 wt.-% SMI/oil dispersion at higher stresses and 35 wt.-% SMI/oil dispersion over the full stress range become viscous. From strain sweep tests, the cross-over of G’ and G” demonstrates linear features at low strain and a transition into viscoelastic properties at high strain. The frequency sweep test indicates a linear solid-like behaviour with storage and loss modulus independent of frequencies at temperatures up to 70 degrees C. From rotational tests, the sensitivity of shear-viscosity properties to concentration and temperature has been demonstrated. The oscillatory and rotational data can be fitted by the Cox-Merz rule using dynamic viscosity and shear viscosity as a function of frequency or shear stress, while a yield point has been detected as a function of shear stress for both 65 and 35 wt.-% SMI/oil dispersions.

Scattering approach to scanning gate microscopy (Reprinted)

KurzfassungWe present a perturbative approach to the conductance change caused by a weakly invasive scattering potential in a two-dimensional electron gas. The resulting expressions are used to investigate the relationship between the conductance change measured in scanning gate microscopy as a function of the position of a scattering tip and local electronic quantities like the current density. We use a semiclassical approach to treat the case of a strong hard-wall scatterer in a half-plane facing a reflectionless channel. The resulting conductance change is consistent with the numerically calculated quantum conductance. (C) 2016 Published by Elsevier B.V.

Structural Redesigning Arabidopsis Lignins into Alkali-Soluble Lignins through the Expression of p-Coumaroyl-CoA: Monolignol Transferase PMT
2016 PLANT PHYSIOLOGY, Band: 170, Nummer: 3, Seiten: 1358 - 1366
KurzfassungGrass lignins can contain up to 10% to 15% by weight of p-coumaric esters. This acylation is performed on monolignols under the catalysis of p-coumaroyl-coenzyme A monolignol transferase (PMT). To study the impact of p-coumaroylation on lignification, we first introduced the Brachypodium distachyon Bradi2g36910 (BdPMT1) gene into Arabidopsis (Arabidopsis thaliana) under the control of the constitutive maize (Zea mays) ubiquitin promoter. The resulting p-coumaroylation was far lower than that of lignins from mature grass stems and had no impact on stem lignin content. By contrast, introducing either the BdPMT1 or the Bradi1g36980 (BdPMT2) gene into Arabidopsis under the control of the Arabidopsis cinnamate-4-hydroxylase promoter boosted the p-coumaroylation of mature stems up to the grass lignin level (8% to 9% by weight), without any impact on plant development. The analysis of purified lignin fractions and the identification of diagnostic products confirmed that p-coumaric acid was associated with lignins. BdPMT1-driven p-coumaroylation was also obtained in the fah1 (deficient for ferulate 5-hydroxylase) and ccr1g (deficient for cinnamoyl-coenzyme A reductase) lines, albeit to a lower extent. Lignins from BdPMT1-expressing ccr1g lines were also found to be feruloylated. In Arabidopsis mature stems, substantial p-coumaroylation of lignins was achieved at the expense of lignin content and induced lignin structural alterations, with an unexpected increase of lignin units with free phenolic groups. This higher frequency of free phenolic groups in Arabidopsis lignins doubled their solubility in alkali at room temperature. These findings suggest that the formation of alkali-leachable lignin domains rich in free phenolic groups is favored when p-coumaroylated monolignols participate in lignification in a grass in a similar manner.

Synthesis of Pyrene-Fused Pyrazaacenes on Metal Surfaces: Toward One-Dimensional Conjugated Nanostructures
2016 ACS NANO, Band: 10, Nummer: 1, Seiten: 1033 - 1041
KurzfassungWe investigated the synthesis of one-dimensional nanostructures via Schiff base (imine) formation on three close-packed coinage metal (Au, Ag, and Cu) surfaces under ultrahigh vacuum conditions. We demonstrate the feasibility of forming pyrene-fused pyrazaacene-based oligomers on the Ag(111) surface by thermal annealing of tetraketone and tetraamine molecules, which were designed to afford cyclocondensation products. Direct visualization by scanning tunneling microscopy of reactants, intermediates, and products with submolecular resolution and the analysis’ of their statistical distribution in dependence of stoichiometry and annealing temperature together with the inspection of complementary X-ray photoelectron spectroscopy signatures provide unique insight in the reaction mechanism, its limitations, and the role of the supporting substrate. In contrast to the reaction on Ag(111), the reactants desorb from the Au(111) surface before reacting, whereas they decompose on the Cu(111) Surface during the relevant thermal treatment.

Tuning thermal release kinetics of soy oil from organic nanoparticles using variable synthesis conditions
2016 PARTICUOLOGY, Band: 26, Seiten: 54 - 65
KurzfassungThe thermal release properties of soy oil from poly(styrene-co-maleimide) nanoparticles containing 50 wt% encapsulated oil have been quantified as a function of temperature and time. The effects of different synthesis conditions on the thermal stability of the nanoparticles and their oil release have been evaluated, i.e., by gradually increasing the amount of ammonium hydroxide used for the imidization of poly(styrene-co-maleic anhydride). First, the intrinsic thermal properties of the oil-filled nanoparticles were analysed by differential scanning calorimetry, which revealed an exothermal reaction related to the oil release and a suppression of the glass transition that may be masked owing to the complex structure of the hybrid nanoparticles. The isothermal scans showed different rates of oil release after a post-imidization reaction. The oil release was better followed by dynamic mechanical analysis, which illustrated changes in visco-elastic properties expressed by the maximum in the loss factor that related to the amount of released oil. Depending on the amount of ammonium hydroxide, the oil started to release below the glass transition temperature at various rates. Thermal release profiles of the oil were quantified by infrared and Raman spectrocopy after heating for 2 min to 6 h at 125 to 250 degrees C, based on variations in oil-related and imide-related absorption bands. The oil release increased below and above the glass transition temperature, following a parabolic trend, and progressively decreased at higher ammonium hydroxide concentrations, in parallel with higher imide content and changes in imide conformation. The kinetics and mechanism of the oil release can be described by the Korsmeyer-Peppas model, suggesting a dominating diffusion mechanism that is influenced by further imidization of the polymer matrix during heating.
