Disorder in Extra-Large Pore Zeolite ITQ-33 Revealed by Single Crystal XRD
No full textThe single crystal of the extra-large pore zeolite, ITQ-33, was obtained and used to explore its crystal structure details. The ITQ-33 structure was found to be disordered with the columnar periodic building unit, explaining the morphology changes upon the different Si/Ge ratio, and the formation of the hierarchical structure from assembling of ITQ-33 nanofibers.Chemistry, MultidisciplinaryCrystallographyMaterials Science, MultidisciplinarySCI(E)EI0ARTICLE104168-41711
Getting everyone onboard: Framing collective goal progress broadens participation in collective marketing campaigns
No full text© 2019 Kim and Reeck. Collective marketing campaigns may feature goals that are not shared equally by all customers, such as a fundraiser for an environmental cause. For such campaigns, how can marketers encourage broad participation? The present research demonstrates that the framing of collective progress in such campaigns can broaden participation by highlighting the “large area” of progress toward the goal, emphasizing progress achieved for campaigns in their late stages and progress remaining in their early stages. We tested this large area hypothesis in the context of a waste reduction drive, examining the reactions of Democrats and Republicans who might be more or less inclined to support the drive respectively. Study 1 examined these processes when the drive was nearing completion, finding that an accumulating frame (focusing on progress achieved) increased motivation to participate for Republicans to levels comparable with Democrats. Study 2 evaluated these processes at earlier stages in the drive’s progress. In these circumstances, a remaining frame (focusing on contributions still needed) increased motivation to participate among Republicans to a similar level as Democrats. These findings indicate framings that highlight the large area in collective progress broaden participation in collective marketing campaigns, suggesting that marketers should highlight remaining contributions needed early on and accumulated contributions received later in collective marketing campaigns
Affective privilege: Asymmetric interference by emotional distracters
No full textNumerous theories posit that affectively salient stimuli are privileged in their capacity to capture attention and disrupt ongoing cognition. Two underlying assumptions in this theoretical position are that the potency of affective stimuli transcends task boundaries (i.e., emotional distracters do not have to belong to a current task-set to disrupt processing) and that there is an asymmetry between emotional and cognitive processing (i.e., emotional distracters disrupt cognitive processing, but not vice versa). These assumptions have remained largely untested, as common experimental probes of emotion-cognition interaction rarely manipulate task-relevance and only examine one side of the presumed asymmetry of interference. To test these propositions directly, a face-word Stroop protocol was adapted to independently manipulate (a) the congruency between target and distracter stimulus features, (b) the affective salience of distracter features, and (c) the task-relevance of emotional compared to non-emotional target features. A three-way interaction revealed interdependent effects of distracter relevance, congruence, and affective salience. Compared to task-irrelevant distracters, task-relevant congruent distracters facilitated performance and task-relevant incongruent distracters impaired performance, but the latter effect depended on the nature of the target feature and task. Specifically, task-irrelevant emotional distracters resulted in equivalent performance costs as taskrelevant non-emotional distracters, whereas task-irrelevant non-emotional distracters did not produce performance costs comparable to those generated by task-relevant emotional distracters. These results document asymmetric cross-task interference effects for affectively salient stimuli, supporting the notion of affective prioritization in human information processing. © 2011 Reeck and Egner

Investigation of nucleation and crystal growth kinetics of nickel manganese oxalates
No full textThe nucleation and the crystal growth rates of mixed nickel manganese oxalates have been determined from the changes of the ionic concentration of the solution and the crystal size distribution during the precipitation process within a supersaturation range 0–0.1 M. Thermodynamic solubility calculations have been used to identify the different species contributing the precipitation reaction and for estimation of the thermodynamic constant. Experimental data show that the nucleation rate of mixed nickel manganese oxalate in this supersaturation range is consistent with a primary heterogeneous mechanism and was found to obey to an exponential law. The crystal growth rates indicate a surface-integration-controlled mechanism with a first-order law with respect to the supersaturation
Finite element method for 3D optical modeling of liquid crystal on silicon spatial light modulator
No full textAccurate optical modeling for design and optimization of liquid crystal on silicon spatial light modulators (LCoS SLMs) is important for phase-related applications. Traditional matrix method cannot accurately predict the optical performance when the LC distribution is complex, therefore the rigorous finite element method (FEM) is preferred. However, the optical modeling of LCoS is a multidimensional problem, which is difficult to simulate with FEM. Here, we present the development of an improved FEM by combining the scattering matrix method with the domain decomposition method to reduce the computational burden for optical simulation of LCoS. Furthermore, a 2D simulation example with phase grating displayed on LCoS is presented and compared with experiment.Grant ID: ColoOpt- EU H2020 ITN 721465ImPhys/Optic
Gel-mediated chemo-mechanical control of calcium carbonate crystal formation
No full textThe production of synthetic crystals with controlled shapes and properties is an enticing prospect, yet, the production of such materials is an ongoing challenge. Here, we present a strategy for chemo-mechanically directing the growth of crystals with non-equilibrium structures using a custom-designed double-diffusion cell. We combine chemical additives (e.g., Mg2+ ions) and mechanical confinement (e.g., hydrogel networks) to modulate the growth of calcium carbonate crystals. Specifically, the combination of Mg2+ ions with a strong agarose gel results in calcitic structures, at the gel-glass slide interface, with distinct fried egg-like morphologies and radial or Maltese-cross extinction patterns. In contrast, precipitation with only Mg2+ or agarose results in aragonite spherulites or squished calcite rhombohedra, respectively. Raman spectroscopy and energy dispersive spectroscopy of the “fried eggs” reveals that they are composed of Mg-calcite, which becomes less disordered over time, and the “egg whites” make this transition before the “yolks”. We propose that the “fried eggs” form due to a spherulitic growth process molded by the crystallization-induced delamination of the gel away from the glass slide at the gel-glass interface. In support of the importance of the gel-glass interface, the “fried eggs” do not form when the glass slide is treated with a hydrophobic silane, suppressing heterogeneous nucleation and weakening the interfacial adhesion between the gel and glass, making it easier for the gel to delaminate, thus reducing the confinement effect. As such, this work highlights the important chemo-mechanical role that gel environments can play in crystal formation.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Materials and Environmen

The self-seeded growth of InAsSb nanowires on silicon by metal-organic vapor phase epitaxy
No full textWe present a study on the growth of InAs1-xSbx alloy nanowires directly on Si (111) substrates via a self seeded mechanism for the first time. Through varying group V flow rate ratios, InAs1-xSbx nanowires with x = from 0 to 0.43 are obtained. It is found that Sb content has a significant effect on the morphology and crystal quality of the formed InAs1-xSbx nanowires. Furthermore, the axial and radial growth rates of the nanowires change in opposite trends with increasing group V flow rate ratio. This indicates that the growth rate of InAs1-xSbx nanowires is ultimately determined by Sb compositions of the nanowires. In addition, the scanning electron microscopy and transmission electron microscopy measurements reveal that the dimensional uniformity and crystal quality of lnAsSb nanovvires with a small amount of Sb compositions are greatly improved compared to the reference lnAs nanovvires. The effect mechanism of Sb on the growth of InAs1-xSbx nanovvires is clarified, which will be a guide for making high quality IRAs' Sb, nanovvires and relevant helerosiruclure devices in the future.
