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…
Tm-doped fiber laser or amplifier can be applied in varied adverse environments. In this work, we demonstrate the pump bleaching of Tm-doped silica fiber with 793nm pump source under gamma-ray irradiation in the range 50Gy-675Gy. The recovery time, the fiber slope efficiency and the fiber cladding absorption spectra a…
Abstract The synthesis of a new mixed metal–organic framework (M′MOF) has been accomplished by the metalloligand approach. [NaCu(2,4‐HPdc)(2,4‐Pdc)] (2,4‐H2Pdc = pyridine‐2,4‐dicarboxylic acid) has been obtained from the hydrothermal reaction of the metalloligand [Cu(2,4‐HPdc)2(H2O)2] NaOH, and a transition metal salt…
We combine supramolecular host–guest interactions of β-cyclodextrin (CD) with light-induced Diels–Alder reactions of 2-methoxy-6-methylbenzaldehyde (photoenol, PE) for the formation of multiblock copolymers. Via the synthesis of a new bifunctional chain transfer agent (CTA) and subsequent reversible addition–fragmenta…
Microwave dielectric ceramics of (1− x )Ba(Mg 1/3 Nb 2/3 )O 3 ‐ x BaSnO 3 [(1− x ) BMN ‐ x BS] with high quality factors was synthesized by the solid‐state reaction method. The effects of BaSnO 3 additions ( x = 0–0.2) on the sinterability, crystal structures, microwave dielectric properties, and microwave dielectric…
Spatiotemporal nanofocusing of ultrafast surface plasmon polaritons (SPPs) coupled on a metal Au tapered tip with a curvature radius of a few tens of nanometers is deterministically controlled based on the measured plasmon response function. We control the SPP pulse shape and the second harmonic generation at the apex…
The voltammetric (CV and DPV) behavior of multi-walled carbon nanotube/Nafion composite coupled with a glassy carbon electrode was investigated for the determination of 2,4-dichlorophenol. The structural and morphological evaluation by XRD and FESEM revealed that the acid treated MWCNT retained their morphology withou…
The effects of constrained sample dimensions on the mechanical behavior of crystalline materials have been extensively investigated. However, there is no clear understanding of these effects in nano-sized amorphous samples. Herein, nanoindentation together with finite element simulations are used to compare the proper…
The new amphiphilic BODPY-porphyrin conjugate BZnPP and its precursor BZnPH were synthesised, and their linear and two-photon photophysical properties, together with their cellular uptake and photo-cytotoxicity, were studied. This amphiphilic conjugate consists of a hydrophobic BODIPY moiety and a hydrophilic tetra(et…
PURPOSE: A type of in vivo dosimeter, an optically stimulated luminescent dosimeter, OSLD, may have dose sensitivity that depends on the angle of incidence of radiation. This work measures how angular dependence of a nanoDot changes with the geometry of the phantom in which irradiation occurs and with the intrinsic st…
