A novel molybdenum- and vanadium-substituted quaternary heteropoly acid H 5 SiW 9 Mo 2 VO 40 [Formula: see text][Formula: see text][Formula: see text]13H 2 O has been synthesized and characterized by IR, UV, TG-DTA and XRD. The proton conductive performance was studied by the electrochemical impedance spectroscopy (EI…
Photoconductor arrays with both high responsivity and large ON/OFF ratios are of great importance for the application of image sensors. Herein, a ZnO vertical nanorod array based photoconductor with a light absorption layer separated from the device channel has been designed, in which the photo-generated carriers alon…
Flow-induced crystallization of α- and γ-phases was studied for a propylene/ethylene random copolymer with 3.4 mol % ethylene at two high temperatures of 132 and 142 °C by combining a pressure-driven slit flow device with real-time synchrotron wide-angle X-ray diffraction. At 132 °C, it was found that both α- and γ-ph…
The importance of carbon deposition occurring during catalytic fuel reforming is briefly described along with former studies on the process. Thermodynamic fundamentals of modeling the critical conditions of the deposition equilibrium are presented. Computational results of ternary C–H–O diagrams with the threshold lin…
Background: We report on the fabrication and characterization of Zinc Oxide (ZnO) and Zinc Oxide Graphene (ZnO-G) composites via a simple chemical route-polyol process, using zinc nitrate hexahydrate, ethylene glycol and reduced graphene oxide (RGO) as the precursors. The ZnO-G composites exhibit significantly enhance…
Abstract Epoxy resins has been the largest industrial thermosetting resins due to their excellent performance. But the degradation and recycling of large amount of cured epoxy resins wastes is still a challenge, inevitably causing serious pollution to the environment. Here, we represent a feasible method to synthesize…
A series of meso - O -aryl functionalized BODIPY trimers positioned along the C 3 -symmetric axis of triazine ring have newly been synthesized to probe the ground and excited state intramolecular type interactions between the BODIPY entities within the trimer. The developed synthetic strategy resulted in BODIPY trimer…
2‐[Bis(4‐amino(nitro)phenyl)aminomethyl]‐9 H ‐thioxanthene‐9‐ones and their S‐oxide derivatives have been synthesized, and their electrochemical reduction (ECR) in N , N ‐dimethylformamide (DMF) and MeCN has been studied by cyclic voltammetry (CV). The thioxanthene‐9‐one group [Th(O)S] and thioxanthene‐9‐one S‐dioxide…
Abstract Eine modifizierte Syntheseroute auf der Basis wasserfreier Seltenerdacetate wurde zur Synthese aufwärtskonvertierender Kern/Schale‐Nanokristalle mit mittleren Größen zwischen 15 bis 45 nm eingesetzt. Die nahezu monodispersen Partikel bestehen aus einem NaYF 4 :Yb,Er‐Kern, dotiert mit 18 % Yb 3+ und 2 % Er 3+…
Abstract The structure, atomic packing density, calorimetric glass transition, and hardness of mixed sodium–lithium germanophosphate oxynitride glasses with varying Ge/P and N/P ratios were investigated. The combined influences of nitridation and mixed network former effect ( MNFE ) on the glass structure were analyze…
We have performed $^{75}\mathrm{As}$ NMR measurements on single crystals to investigate the nematic behavior via the in-plane anisotropy of the electronic state at the As site far from Co impurities in the representative iron arsenides $\mathrm{Ba}{({\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Co}}_{x})}_{2}{\mathrm{As}}_…
Abstract Electrospun scaffolds constituted by different mixtures of two biodegradable polyesters are prepared. Specifically, materials with well differentiated properties can be derived from the blending of hydrophilic polyglycolide (PGA) and hydrophobic poly(ε‐caprolactone) (PCL), which are also two of the most appli…
Abstract The emergence of piezoelectric polymers in magnetoelectric (ME) composites enables flexible and low‐cost device fabrication though notably gives rise to the highest ME output voltages to date. Accordingly, the highest piezoresponsive polymers, poly(vinylidene fluoride) (PVDF) and its copolymers, are exclusive…
Moisture-resistant silicone coatings were prepared on the surface of potassium dihydrogen phosphate (KDP) crystal by means of spin-coating, in which hydrophobic-modified SiO₂ nanoparticles were embedded in a certain proportion. The refractive index of such coating can be tuned arbitrarily in the range of 1.21⁻1.44, wh…
(HCc). HCc, an extensively studied and well-characterized protein, represents an ideal model for nanoparticle (NP)-protein conjugation studies because of its small size, high stability, and commercial availability. Here, the native state of the protein has been demonstrated for the first time, by means of Raman spectr…
ABSTRACT Polymerization of crosslinkable liquid crystal monomers in chiral liquid crystalline media stabilizes the phase and enables distinct electro‐optic properties relative to small‐molecule analogs. Particularly interesting are cases where the polymerization forms a crosslinked polymer network that maintains a “st…
In the tireless search for innovative and more efficient cancer therapies, sonosensitive Magnetic Resonance Imaging (MRI) agents play an important role. Basically, these systems consist of nano/microvesicles composed by a biocompatible membrane, responsive to ultrasound-induced thermal or mechanical effects, and an aq…
Abstract A one‐step strategy to fabricate magnetically stirrable microparticles with geometric/chemical anisotropies via a microfluidic technique combined with partial phase separation is presented. Monodisperse oil‐in‐water microemulsions composed of magnetite nanoparticles (MNPs) and two polymers, polystyrene and po…
Tristriazolotriazines (TTT) are new tetracyclic and planar cores for discotic liquid crystals. Two symmetrical isomers are known, paddle‐wheel type t ‐TTTs and r ‐TTTs with the shape of a propeller. Cyclocondensation of chlorotriazoles gives r ‐TTTs, Huisgen reaction of tetrazoles and cyanuric chloride yields t ‐TTTs…
Crosslinked cationic nanoscale networks with hydrophobic cores are an environmentally robust alternative to self-assembled polymeric drug delivery carriers with respect to therapeutic encapsulation and stability to dilution. However, the ability to tune the degree of PEG incorporated into nanogels during synthesis is…
