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 ...

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:
... A novel synthetic strategy for low-symmetry phthalocyanines has been developed, which involves the base-promoted cyclization of a preconnected trisphthalonitrile and a free phthalonitrile in the presence of a metal template. By using this [3 + 1] mixed cyclization approach, a series of zinc(II) phthalocyanine derivatives have been synthesized in up to 12% yields, including a very rare ABCD-type ph ...

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:
... Interleaving fiber reinforced layered composites with thermoplastic veils is a strategy that has been examined by using electrospun fibers of homopolymers as well as their physical mixtures. Separate toughening mechanisms were activated by the individual presence of the physically mixed fibers in previous studies. Here, we show that it is possible to initiate a concerted action of these mechanisms ...

Abstract:
... Broken rice can gather in the core of a cylinder during rice grain separation because it is wrapped by whole rice and cannot contact the indents causing low separation efficiency. To improve contact with the indented cylinder by broken rice the actions of a baffle were simulated using the discrete element method. By analysing rice movement in the mixing area under the action of baffle, the mechani ...

In the set first (set I) three different parameters namely grams/m² (GSM), needling density and blend ratio with three different levels and in the second set (set II) three different parameters, i.e. calender roller pressure, calender rol ...

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:
... Bulk rheology measurements on concentrated monodisperse ring–linear DNA mixtures are reported for the first time. The entanglement behavior of the ring–linear DNA mixtures (with 15 and 50% linear chain fractions, ϕLᵢₙ) over a range of total DNA concentration, ϕTₒₜ, from ∼0.8 mg/mL (20C*) to 2 mg/mL (50C*) is reported. A discussion on the current problems in the reported ring dynamics/scaling is in ...

Abstract:
... Quantum dot light-emitting diodes (QLEDs) have promising commercial value and application prospects in the fields of displays and lighting. However, a charge-transfer imbalance always exists in the devices. In this work, the high-efficiency red QLEDs were obtained via employing the mixtures of poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt-(4,4′-(N-(4-butylphenyl) (TFB) and 4,4′-bis(carbazole-9-yl)-1,1′ ...

Abstract:
... We have demonstrated the effects of different chain lengths on the phase behavior in films of binary blends of four different weight fractions in a weak segregation limit. The binary blends were composed of nearly symmetric polystyrene-block-poly(methyl methacrylate), PS-b-PMMA, and homo-polystyrenes (PS) of three different molecular weights (hereafter hPS².⁸, hPS⁶, and hPS¹⁷). Films of two initia ...

Abstract:
... The standard methodology employed for estimating homogeneity of powder mixtures relies on the concept of scale of scrutiny. This parameter defines the relevant scale at which a homogeneous distribution of a given compound is critical regarding the final application of the blend. However, such a scale is not always known in advance. In this paper, a process involving two ceramic powders, co-ground ...

Abstract:
... The operator splitting approach has been widely accepted since it was introduced as a means to solve reactive transport problems. The conventional operator-splitting finite element scheme (Nodal-OS) handles speciation calculations on nodes, resulting in a mixing of heterogeneous reactions on opposing sides in multi-layer systems. Such mixing, however, is not physically accurate. In this context, w ...

Abstract:
... Oberservation of particle movement during wet granulation is crucial for identifying granulation mechanisms, process optimizations and troubleshooting. An example of such a process is spheronization, which is commonly used as a wet granulation technique to produce spherical, pharmaceutical pellets. Due to the dense particle bed, measurements of poloidal pellet velocities remain a challenge and hav ...

Abstract:
... Hyper-wavelet transforms such as the non-subsampled shearlet transform (NSST) are popular algorithms to remove random noise and clutter in ground penetrating radar (GPR) images. However, due to the effect of time-varying gain, random noise and clutter in GPR images are non-stationary. Moreover, random noise which is poorly correlated among pixels and clutter which shows a certain correlation among ...

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.
