Steady-state bifurcation analysis is applied to a ternary benzene–toluene–xylene (BTX) dividing wall column (DWC) to synthesize robust temperature inferential controlled variables (CVs). The coupling between the prefractionator and the main column causes steady-state multiplicity in conventional tray temperature CV lo…
By the combination of high-speed imaging and numerical simulation, we explore the hydrodynamics and possible morphologies of the entire coalescence of a pendent droplet and sessile one. We identify three types of coalescence morphologies and plot a corresponding phase diagram to identify them depending on the Bond num…
Examination of the bulbs of Lilium pumilum (Liliaceae) led to the isolation of four novel steroidal glycosides (1-4) with a 2,3,4-trisubstituted β-d-glucopyranosyl unit. In 1 and 3, the α-L-arabinopyranosyl moiety is linked to C-3 of the inner trisubstituted β-D-glucopyranosyl group and is present as an usual ⁴C₁ conf…
We demonstrate that optical absorption spectra of CdS thin films in the visible/near ultraviolet range can be precisely described by four different contributions of electron transitions from Γ points of three branches of the valence band maxima (Γ 7 , Γ 9 , Γ 7' ,) to the lowest two minima in the conduction band (Γ e…
Artificial spin ices are often spoken of as being realisations of some of the celebrated vertex models of statistical mechanics, where the exact microstate of the system can be imaged using advanced magnetic microscopy methods. The fact that a stable image can be formed means that the system is in fact athermal and no…
We studied the collective motion of particles forced to move along a circular path in water by utilizing an optical vortex. Their collective motion, including the spontaneous formation of clusters and their dissociation, was observed. The observed temporal patterns depend on the number of particles on the path and the…
Abstract Stepwise reduction of 9,10‐bis(dimesitylboryl)anthracene afforded an radical anion and a dianion, accompanied by stepwise changes of the aromaticity of the anthracene moiety. The radical has a planar semiquinoidal structure, while the dianion has a puckered quinoidal structure. The alteration of the geometrie…
A compact (15µm × 15µm) and highly-optimized 2×2 optical switch is demonstrated on a CMOS-compatible photonic crystal technology. On-chip insertion loss are below 1 dB, static and dynamic contrast are 40 dB and >20 dB respectively. Owing to efficient thermo-optic design, the power consumption is below 3 mW while the s…
The transport of water molecules through carbon nanotubes (CNTs) is of primary importance for understanding water-mediated biological activities as well as for the design of novel nanoporous materials. Herein, we analyze the water flow through CNTs by using molecular dynamics simulations with the hope of finding basic…
Abstract Guanidino‐functionalized aromatic compounds (GFAs) are strong organic electron donors and redox‐active ligands. The diversity of GFA chemistry results from reaction sequences that are triggered by their oxidation. This work reports on reactions of a new GFA compound, namely, 1,2,4,5‐tetrakis(N,N′‐dicyclohexyl…
Special characteristics of wrinkles such as a scattering source and a high surface area are finding use in high-tech applications. UV-crosslinkable prepolymers are occasionally used for fabricating wrinkled films. Wavelength of the wrinkles formed from the prepolymers is several tens and hundreds of micrometers. Here,…
Evaluation and control of a polarization state of optical near fields are of tremendous advantage for locally probing intrinsic molecular orientations of highly anisotropic molecules with a plasmonic (metallic) nanoantenna. In this paper, we report on a physical mechanism of reading a dipole orientation at the apex of…
Abstract Raw clay, which is an interstratified illite‐kaolinite, has been used as a raw material to prepare Faujasite‐type zeolites. The synthesis was based on the alkaline fusion method followed by hydrothermal treatment without the addition of any extra silica or alumina sources. The effects of various factors on th…
Poria cocos Wolf., which belongs to the Polyporaceae family, has been widely used as an Oriental traditional herbal medicine for centuries. Its sclerotium has been reported to possess a wide spectrum of pharmacological activities, including free-radical scavenging, anti-viral, anti-microbial, anti-inflammatory and ant…
A series of isostructural trinuclear complexes of metal composition Pd 2 Fe, Pd 2 Co, and Ni 2 Fe was synthesized in a stepwise fashion. Using dinuclear precursors (Pd I 2 and Ni I 2 ) supported by p -terphenyl diphosphine ligands allowed for the selective incorporation of a single additional metal center. The effects…
The interplay between spin and charge in solids is currently among the most discussed topics in condensed matter physics. Such interplay gives rise to magneto-electric coupling, which in the case of solids was named magneto-electric effect, as predicted by Curie on the basis of symmetry considerations. This effect ena…
On the basis of proton transfer in aqueous phase, we prepared a water-soluble and highly fluorescent ionic complex of 3,4,9,10-perylene tetracarboxylic acid (PTCA) and 6-deoxy-6-amino-β-CD (β-CDNH2) and studied its fluorescence behavior. It was found that the fluorescence emission of the complex is sensitive and selec…
Microporous structures are usually designed for hemostatic agents to dehydrate blood and thus accelerate the natural clotting process. We have developed gelatin-based fibrous membranes by co-electrospinning with a hydrophobic protein, zein, for hemostatic dressings. The hybrid gelatin/zein fibers showed structural int…
We suggest a more nuanced view of the merit and utility of generalized gradient approximations (GGAs) for the noninteracting kinetic energy (KE) than the critique of Xia and Carter (XC) [Phys. Rev. B 91, 045124 (2015)]. Specifically, the multiple valuedness of the Pauli term enhancement factor (denoted $G[n]$ by XC) w…
This paper describes a lamination method of commercially produced silica aerogel composite and investigates its suitability for thermal insulation within protective footwear applications for severe cold and extreme high-altitude environments. A silica aerogel composite was used with a thickness of 2.7 mm and mass per…
