The study of 27 new meso-substituted free-base and metal complexes of tetraphenylporphyrins with substitution by alkoxygroups (from -OC4H9 to -OC16H33) in para-, meta-, or ortho-position has been carried out. Out of 11 synthesized free-base alkoxysubstituted tetraphenylporphyrins – 4 possess mesomorphic state of colum…
Zink macht den Unterschied: Das Polyoxometallat 1 reagiert mit Zn2+-Ionen in Aceton nahezu quantitativ zum neuartigen Sandwich-artigen POM 2. Die Oxidation sekundärer Alkohole mit H2O2 verläuft mit 2 effizient, und zwar mit Aktivitäten und Chemoselektivitäten, die sich von denen wolframhaltiger Katalysatoren einschlie…
High cesium (Cs)‐bearing sodium borosilicate glasses incorporated with varying concentrations of TiO 2 up to 10 mol% at the expense of B 2 O 3 were prepared by the conventional melt quenching method. Physicochemical properties of the glasses studied include Cs volatilization losses, leaching, and glass transition temp…
Gold nanorods can be used as extremely bright labels for differential light scattering measurements using two closely spaced wavelengths, thereby detecting human disease through several centimeters of tissue in vivo. They have excellent biocompatibility, are non-toxic, and are not susceptible to photobleaching. They h…
Bi 0.90 La 0.10 Fe 0.95 Zn 0.05 O 3 (BLFZO) thin films were grown directly on Pt/TiO2/SiO2/Si(100) substrates without any buffer layer by off-axis radio frequency sputtering. The BLFZO thin film deposited at 580 °C possesses a single-phase purity, while those deposited at other temperatures exhibit a varying amount of…
A laboratory incubation experiment using soil columns was conducted to study the effects of monocalcium phosphate (MCP) and potassium chloride (KCl) on soil pH changes in fertilizer microsites with two Chinese soils. Mixtures of two fertilizers at two rates (0 and 0.26 g per column) were added to the surface of soil c…
The spectra of far-infrared transmission in ${\text{Tb}}_{3}{\text{Fe}}_{5}{\text{O}}_{12}$ magnetoelectric single crystals have been studied in the range between 15 and $100\text{ }{\text{cm}}^{\ensuremath{-}1}$, in magnetic fields up to 10 T, and for temperatures between 5 and 150 K. We attribute some of the observe…
Abstract The solvothermal reactions of Ti(O i Pr) 4 in alcohol using ionic liquid as additive were investigated. In the presence of [BMIM][Cl], [BMIM][Br], [BMIM][NTf 2 ], [BMIM][SO 3 Me], [BMIM][SO 4 Me], or [BMIM][OTf] (BMIM = 1‐Butyl‐3‐methylimidazolium), pure anatase nanoparticles were obtained. The controlled hyd…
Abstract Alginate‐ g ‐vinyl sulfonic acid graft copolymer was synthesized through the graft copolymerization of vinyl sulfonic acid (VSA) onto alginate with an efficient system, i.e., potassium peroxydiphosphate (PDP)/thiourea in an aqueous medium. The effects of the concentration of thiourea, PDP, hydrogen ion, algin…
Atomistic simulations and a dislocation-based analysis reveal the mechanism of carbon peapod fusion into double-walled nanotubes. They explain the trend of diameter increase for the emerging inner wall, driven by the reduction in its strain energy and the interwall van der Waals energy. Surprisingly, this is also acco…
Abstract Low‐density polyethylene/layered double hydroxide (LDPE/LDH) nanocomposites were prepared via melt extrusion using organo‐LDH particles and maleic anhydride functionalized polyethylene as compatibilizer. Processing parameters, preparation method, and feed composition were properly modulated until obtaining na…
An outstanding challenge in biomedical sciences is to devise a palette of molecular probes that can enable simultaneous and quantitative imaging of tens to hundreds of species down to ultralow concentrations. Addressing this need using surface-enhanced Raman scattering-based probes is potentially possible. Here, we th…
Acid does the trick: A novel 1,10-phenanthroline-embedded sapphyrin analogue 1 (see scheme; R=COOEt, Ar=p-tolyl) bearing meso alkylidenyl double bonds has been synthesized. Interestingly, the protonated form of 1 ([1⋅3 H]3+) exhibits singlet biradicaloid character.
This paper is focused on the optical properties of nanocomposite plasmonic emitters with core/shell configurations, where a fluorescence emitter is located inside a metal nanoshell. Systematic theoretical investigations are presented for the influence of material type, core radius, shell thickness, and excitation wave…
Ferromagnetic shape memory effects of antiperovskite Mn 3 CuN are markedly altered by nitrogen deficiency. The martensitic transformation occurs at a lower temperature than ferromagnetic ordering for nitrogen-deficient Mn 3 CuN 0.8 , although they both occur simultaneously for stoichiometric Mn 3 CuN. In the martensit…
The dynamical control of the dielectric response in magnetoelectric (ME) nanocomposites (NCs) renders an entire additional degree of freedom to the functionality of miniaturized magnetoelectronics and spintronics devices. In composite materials, the ME effect is realized by using the concept of product properties. Thr…
Dense self-avoiding polymer chains in strictly two dimensions are compact objects with fractal contours. Using scaling arguments and molecular dynamics simulations (with negligible momentum conservation) it is shown that correlated amoebalike fluctuations of the (sub)chain contours dominate the relaxation dynamics on…
The spin-wave band structures of two-dimensional magnonic crystals with different shapes and arrangements of scatterers are investigated numerically. It is shown that the magnonic band gap of spin waves in magnonic crystals can be optimized by changing the shape or the arrangement of scatterers in background materials…
The established electron backscatter diffraction (EBSD) technique for obtaining crystallographic information in the SEM has been adapted to permit elastic strain measurement. Basically, the displacement of crystallographic features in an EBSD pattern, such as zone axes, which result from strain in a crystal, is determ…
