mixing, etc ; electrons; hydrogen bonding; thermodynamics; Show all 4 Subjects
Abstract:
... In-depth elucidation of how molecules are electrically polarized would be one key factor for understanding the properties of those molecules under various thermodynamic and/or spatial conditions. Here this problem is tackled for the case of hydrogen-bonded water by conducting singular value decomposition of the electron density changes that occur upon electrostatic polarization. It is shown that a ...
... Quasi-2D perovskites are potential materials for optoelectronics like light-emitting diodes (LEDs); compared to their 3D counterparts, they are considered more stable against the atmosphere and more efficient in exciton confining. However, the simultaneous formation of different phases in the quasi-2D perovskite film, i.e., the phase impurity issue, lowers the device performance. We propose using ...
mixing, etc ; Bayesian theory; economics; experimental design; Show all 4 Subjects
Abstract:
... We report the results of two pre-registered experiments designed to study the reinforcement paradox: increased incentives often fail to increase and sometimes even decrease performance in Bayesian updating tasks. We argue that, in the presence of win/loss cues, higher incentives have two countervailing effects: increased error rates for reinforcement behavior (win-stay, lose-shift) and increased p ...

Abstract:
... In the present study, a six-directional sampling method (SDSM) and six-directional sampling mean mixing indices (SDS-mMI) [i.e., SDS-mLMI, SDS-mRSD, and SDS-mSMI] based on SDSM are proposed for the first time by considering Lacey mixing index (LMI), relative standard deviation (RSD) and sub-domain mixing index (SMI) as basis to assess the solids blending performance in DEM simulations. The propose ...

Abstract:
... This study investigated potentially affiliative behaviors in grow-finish pigs, how these behaviors changed over time and their relationship to agonistic behaviors. A total of 257 Yorkshire barrows were observed for agonistic (reciprocal fights, attacks) and affiliative (nosing, play, non-agonistic contact) behaviors after mixing (at 10 weeks of age), and weeks 3, 6, and 9 after mix. The least squa ...

Abstract:
... Micromixers with concave wall-based mixing chambers and convex wall-based constriction channel are studied. The effect of shape and aspect ratio of the obstacle on mixing performance was investigated for the Reynolds number in the range of 0.1–75 using Computational Fluid Dynamics (CFD). The micromixers showed interesting mixing dynamics and flow features in respect of two flow regimes identified ...
... Suppressing intramolecular vibration of non-fullerene acceptors (NFAs) by molecular rigidification has been proven to be an effective way to reduce the non-radiative recombination loss and energetic disorder of organic solar cells (OSCs). Thus far, extensive attention has been drawn on rigidifying the fused-ring backbones of NFAs, whereas the highly flexible alkyl side chains are barely concerned. ...
... This study attempts to provide a more precise and comprehensive model for stream-wise velocities in turbulent smooth-wall open channel flows. Velocity profiles are obtained from the resolution of two ordinary differential equations. The first is derived from the Reynolds-averaged Navier-Stokes (RANS) equation while the second is from the equilibrium between turbulent kinetic energy (TKE) productio ...
... The precise control of two-dimensional supramolecular co-assemblies presents a research topic related to advance nanotechnology. Here, we report a scanning tunneling microscopy (STM) study of the mixture behavior of three fluorenone derivatives at the liquid–solid interface. The target molecule is F–C₁₂C₁₃ whose structure bears asymmetrical alkyls, whereas the regulating molecules, either F–C₁₂C₁₂ ...

Abstract:
... With a growing interest in precise and sensitive diagnosis for criminal investigations, nanoparticles (NPs) have intrigued scientific minds working in the field of forensic science due to their exceptional properties. Magnetic nanoparticles (MNPs) have emerged as a powerful tool for improving forensic analysis due to their super magnetic behavior combined with smaller dimensions. MNP-based applica ...

Abstract:
... Charge-driven self-assembly of cationic zirconium-based metal–organic polyhedra (MOPs) with polyoxometalates (POMs) leads to a series of porous crystalline salts, prepared by simple mixing of soluble precursors. The reactivity of immobilized POMs was greatly increased, as demonstrated by their fast reduction by hydrazine vapors, without loss of structural integrity. ...

Abstract:
... This study investigated the Comil as a dry-coating process to enhance the flowability of pharmaceutical powders. As a major novelty, the mean residence time was measured and the effect of processing conditions on the extent of flowability enhancement was evaluated. As opposed to previous work which used a “multi-pass” approach to increase residence time and to improve the effectiveness of the Comi ...

Abstract:
... We first study the optimality of a committed policy mix of tax and subsidy to control pollution when firms are involved in abatement technology R&D that is subject to knowledge spillovers. Then a comparison of tax and subsidy is provided when the policy mix is not available and the regulator can use only one single policy. Two different behavioral assumptions for the firms are examined: when firms ...

Abstract:
... Mixtures of colloids and supramolecular polymers may exhibit stimuli-responsive phase behaviour. However, in theoretical descriptions of such systems, the polymers are commonly described either as flexible chains or as rigid rods, while in experimental systems supramolecular polymers usually fall in between these two limits. We expect the flexibility of the polymers to have a profound effect on th ...

Abstract:
... This study investigates the effects of space allowance (SA), mixing and phase feeding (PF) on performance of grower-finisher pigs. Three trials (T) were conducted. In T1 and T2, 345 pigs/trial were moved to finisher stage at 11 weeks of age and assigned to two SAs: 0.96 (n = 15 pens; 10 pigs/pen) and 0.78 (n = 15; 13 pigs/pen) m²/pig. Mixing was applied to 5 pens of each SA leading to a 2 × 2 fact ...

Abstract:
... In this study, the performance of two routing procedures were evaluated to estimate the two-dimensional dispersion coefficients. The two-dimensional Stream-Tube Routing Procedure (2D ST-RP) has been widely used to obtain the dispersion coefficients from measured concentration-time curves under the frozen cloud assumption. Meanwhile, the Spatial Routing Procedure (2D S-RP) employs the spatial distr ...

Abstract:
... Two indacenodithiophene (IDT)-based small-molecule analogues (IDBT and IDBT-Cl) are designed as donor materials for organic solar cells. Relative to the amorphous IDBT-Cl, the IDBT with strong crystallinity shows overall better photovoltaic performance when blended with a Y6 acceptor. The results demonstrate the great potential of IDT units in designing efficient small-molecule donors. ...

Abstract:
... Organic charge transfer complexes (CTCs) with near-infrared absorption received growing interest in the past years, but the details of their photophysics, especially in thin films, remain largely unknown. We combined experimental and computational methods to thoroughly investigate and compare CTCs formed by tetracene with 2,2′-(perfluoronaphthalene-2,6-diylidene)dimalononitrile and 2,3,5,6-tetrafl ...

Abstract:
... Recent structural studies show distinct morphologies for the fibrils of Aβ(1–42) and Aβ(1–40), which are believed not to co-fibrillize. We describe here a novel, structurally-uniform 1 : 1 mixed fibrillar species, which differs from both pure fibrils. It forms preferentially even when Aβ(1–42) : Aβ(1–40) peptides are mixed in a non-stoichiometric ratio. ...

The experimental data on the influence of dynamical impact by mixing on flow parameters were obtained. Averaged turbulent characteristics were measured at different rotation velocities of mixers and at different distances from them. Optical measurements yie ...
