Micro-tubular SOFCs have the potential to become light-weight portable auxiliary power units for aircraft or spacecraft.
Cyclic voltammograms, UV-visible and FT-IR spectra show that porphyrins with two N-methyl-3-pyridylethynyl substituents can undergo reductive electropolymerization on Pt and ITO electrodes. The films are redox active and a mechanism is suggested.
Large dendritic assemblies terminated by organometallic groups that possess a rich redox chemistry and stability in two or more oxidation states are highly desired as electron-reservoir systems, sensors, and redox catalysts. Here the synthesis and click (CuAAC) chemistry of ethynyl biferrocene including branching onto…
Graphene sheets (GNS) were synthesized continuously by spray pyrolysis of iron carbonyl and pyridine. The Pt catalyst supported on GNS exhibited excellent durability for oxygen reduction reaction (ORR). The GNS, when used as a metal-free catalyst for ORR, showed performance even better than the commercial Pt/C catalys…
Nanoporous silver microstructures were successfully fabricated from hexapod AgCl microstructures <italic>via</italic> a galvanic replacement reaction to be used as an easy handling and reusable SERS substrate.
The simple reaction of phenylthiol with 8-MeS-BODIPY (1) in dichloromethane was readily accomplished to form 8-PhS-BODIPY (2). If the reaction is performed in THF 3,8-bis(phenylthio)-BODIPY (3) and 3,5,8-tris(phenylthio)-BODIPY (4) are sequentially formed in an unprecedented reaction. This provides a simple new method…
Manufactured nanomaterials (MNMs) are increasingly incorporated into consumer products that are disposed into sewage. In wastewater treatment, MNMs adsorb to activated sludge biomass where they may impact biological wastewater treatment performance, including nutrient removal. Here, we studied MNM effects on bacterial…
A series of neutral yttrium guanidinates supported by an amine-bridged bis(phenolate) ligand were synthesized, and their catalytic behaviors for the ring-opening polymerization of 1,4-dioxan-2-one ( p -dioxanone, PDO) were explored. Metathesis reactions of amine-bridged bis(phenolate) yttrium chlorides LLnCl(THF) [L =…
Misfit layer compounds are structures that consist of two sublattices differing in at least one of their lattice constants. The two different layers are stacked either an alternating or in a more complex series resulting in mono- or multi-layer misfit compounds. To date, planar and bent misfit structures, such as tube…
NaBa(1-x)Ca(x)PO4:Eu(2+) were synthesized using polymerizable complex method. New phases were observed at x = 1/3 and 0.5, which were identified by single-crystal XRD analysis as Na3Ba2Ca(PO4)3 and NaBa0.5Ca0.5PO4 with a trigonal system. Though both phases pretend to be solid solutions between NaBaPO4 and NaCaPO4, the…
Electrically driven energy transfer between the surface defect states of ZnO quadrilateral microwires (MWs) and localized surface plasmon polaritons has been realized by means of introducing Au nanoparticles (NPs). An electroluminescence device with green emission using ZnO quadrilateral MWs, was fabricated. Once the…
The behavior of melt-grown mixed-brushes was studied and compared with the behavior of the corresponding solution-grown matrix-dispersed mixed-brushes.
We report the synthesis of rare-earth amides and their catalytic activity in ROP of lactide.
The fluorescence and room temperature activity of a palygorskite supported Y2O3:(Eu(3+),Au(3+)) nanocomposite were investigated to design a fluorescence-indicated catalyst. The effects of Au(3+) doping on the structure and surface properties of the host material were systematically characterized. The fluorescence inte…
Pd–Pt core–shell/frame bimetallic nanocrystal has attracted great interest in the applications of catalysis, plasmonics, and electronics. Controlling the shape, morphology, and chemistry of the outer Pt layer has been widely accepted as a critical factor to the realization of these applications. In this study, we prov…
A turn-on detection of pyrophosphate based on the aggregation-induced emission property of 5-chlorosalicylaldehyde azine has been established.
microparticles via EDTA treatment. During the preparation process, the organic layer is formed through the blending of cationic polyethylenimine (PEI) and polydopamine (PDA) derived from the spontaneous oxidative polymerization of dopamine. The inorganic layer (mineral layer) is formed through the hydrolysis/condensat…
Red Ca0.99Al(1-4δ/3-x)Si(1+δ+x)N(3-x)C(x):Eu(2+)0.01 (δ = 0.345; x = 0-0.2) nitride phosphors exhibit a blue-shifted emission with increased eye sensitivity function and excellent thermal stability. The variations in the photoluminescence in the Ca0.99Al(1-4δ/3-x)Si(1+δ+x)N(3-x)C(x):Eu(2+)0.01 (δ = 0.345; x = 0-0.2) s…
Medical applications of the superantioxidant ceria nanoparticles (CeNP) are limited due to their high toxicity and low stability. CeNP toxicity is related to their aggregation in solution, and the possible generation of reactive oxygen species (ROS) by a Fenton-like reaction. For the efficient medical application of C…
