We report the synthesis, structural characterization, and ionic conductivity measurements for a new polymorph of bismuth vanadate Bi 46 V 8 O 89, and an ab initio molecular dynamics study of this oxide ion conductor. Structure determination was carried out using synchrotron powder X-ray and neutron diffraction data; i…
XBroad is a public domain program designed for easy determination of basic microstructural information from powder X-ray diffraction data. Nowadays, preparation of nanomaterials with controlled particle size and shape has been found to be essential for tailoring the desired material properties, so a quick and effectiv…
Tenside mit anorganischen Kopfgruppen, bestehend aus einem rutheniumsubstituierten Polyoxowolframatcluster, demonstrieren das außergewöhnliche Potenzial einer synergistischen Kombination von Selbstorganisationseigenschaften und stimuliresponsivem Verhalten. Das System antwortet dynamisch auf chemische Reize (etwa durc…
Translucent MgAl2O4 was prepared by combustion synthesis melt-casting under high gravity. Compared with common gravitational condition, under high-gravity condition the separation between ceramic and metal melts was accelerated, and thus the content of residual Ni in MgAl2O4 ingot was reduced. By the incorporation of…
A series of novel liquid crystalline supramolecular networks formed through competitive hydrogen bonding has been synthesised. These networks are composed of a flexible bis-cinnamic acid and two types of pyridyl species – a small rigid bipyridyl capable of forming liquid crystalline phases and polyfunctional non-mesog…
Abstract To improve the interfacial performance of poly[p‐phenylene benzobisoxazole] (PBO) fiber and epoxy resin, a modified multiwalled carbon nanotubes (MWCNTs‐Ecp) were used to achieve this purpose through grafting onto PBO fiber surface using a gamma ray radiation method. Experimental results indicated that the eq…
Freshly prepared red selenium and the copper(I) reagent [Cu(1,2-F2C6H4)2][A] are the key to the salts [Cu2Se19][A]2 and [Cu2Se19][A]2⋅0.5 Na[A] ([A]=[Al(ORF)4], RF=C(CF3)3), which provides the first structurally characterized E19 ring of any element E. The unusual [Cu2Se19]2+ ion contains two Cu+ ions that stabilize t…
In this work, a novel nucleating agent (NA) based on substituted‐aryl phosphate salts was introduced into poly(L‐Lactide) (PLLA). The nonisothermal and isothermal crystallization behaviors of nucleated PLLA samples were investigated through differential scanning calorimetry (DSC), wide angle X‐ray diffraction, and pol…
A series of four mixed (phthalocyaninato)(porphyrinato) rare earth double-decker complexes (Pc)M[Por(Fc)(2)] [Pc = phthalocyaninate; Por(Fc)(2) = 5,15-di(ferrocenyl)-porphyrinate; M = Eu (1), Y (2), Ho (3), Lu (4)] and their europium(III) triple-decker counterpart (Pc)Eu(Pc)Eu[Por(Fc)(2)] (5), each with two ferrocenyl…
Varying the concentration and molar ratio between aniline and AuCl 3 leads to a series of Au/polyaniline (PANI) nanocomposites with a wide range of morphologies ranges from nanosphere, nanorod, to complex nanosheet assemblies. These nanocomposites consist of an ensemble of very small Au nanoparticles held together by…
Abstract A new open‐framework manganese borophosphate, KMnBP 2 O 7 (OH) 2 , has been prepared under ionothermal conditions in the ionic liquid 1‐butyl‐1‐methylpyrrolidinium bromide. Single‐crystal X‐ray diffraction analysis showed that KMnBP 2 O 7 (OH) 2 [monoclinic, P 2 1 / c , a = 6.659(1), b = 12.049(2), c = 9.790(…
We fabricated the parabola-shaped subwavelength grating (SWG) nanostructures on indium tin oxide (ITO) films/Si and glass substrates using laser interference lithography, dry etching, and subsequent re-sputtering processes. The efficiency enhancement of an a-Si:H/μc-Si:H tandem thin film solar cell was demonstrated th…
Einzelmolkülmagnete: Ein Cyanid-verbrückter sechskerniger Eisen(III)-Cobalt(II)-Komplex Komplex zeigt bei 220 K einen Spinübergang, der an einen thermischen Elektronentransfer gekoppelt ist. Lichteinstrahlung bei tiefer Temperatur (LT; HT=hohe Temperatur) erzeugt einen metastabilen Zustand, der beim Messen der magneti…
The experimentally known perovskite-like materials BaYMn 2 O 5+δ (δ = 0, 0.5, 1) are characterized by a remarkably reversible oxygen-storage capacity at a moderate 500 °C. We try to elucidate the local structures of the vacancy arrangements in these compounds taking place after an oxygen release. This is done for the…
Here, we report the use of tetraoctylammonium bromide (TOABr)-coated Au nanoparticles (NPs) for the optical sensing of volatile organic compounds (VOCs). We find that the film responded selectively to the presence of polar and nonpolar vapors by changes in the maximum wavelength (λ(max)) toward higher and lower wavele…
Abstract The preparation and physical characterization of diverse porphyrin‐derived double‐walled carbon nanotubes (DWCNTs) conjugates are described. A porphyrin molecule is covalently linked and physically adsorbed to COOH‐derived DWCNTs. The photophysical properties of all porphyrin‐CNTs derivatives are studied in s…
Abstract Nanoclay‐encapsulated polystyrene microspheres were synthesized using reverse atom transfer radical polymerization in miniemulsion. Conversion and molecular weight were evaluated using gravimetry and gel permeation chromatography, respectively. Accordingly, conversion and molecular weight decrease by adding c…
The stability of silk proteins to ultraviolet light is an issue of significant concern in both the appearance retention of silk-derived products and the preservation of historic silk textiles. Until now, evaluation of silk degradation has only been performed at the holistic, rather than molecular level. This article d…
Fly ash cenospheres are inexpensive, readily available from coal burning or heavy oil combustion, not an eco-friendly material. If ways can be found to use this, it will serve the twin purposes of facilitating applications for the ash bearing materials and at the same time reduce pollution. One way to achieve this tas…
Modulation excitation spectroscopy is a powerful and well established technique for investigating the dynamic behaviour of chemical and physical systems. Recently, an expansion of this technique for diffraction was proposed and the theory deriving the diffraction response of a crystal subjected to a periodically varyi…
