Abstract Ultrathin composite films consisting of mixtures of metallic (m‐) and semiconducting (s‐) single‐walled carbon nanotubes (SWNTs) with a conjugated block copolymer are developed from a solution‐based process. The electronic properties of the films are precisely controlled from metallic to semiconducting to ins…
In this paper, the superconducting properties of ${\text{YSn}}_{3}$ are reported. ${\text{YSn}}_{3}$ has a cubic ${\text{AuCu}}_{3}$-type structure with the space group $Pm\overline{3}m$. Magnetic susceptibility, electrical resistivity, and specific-heat data showed that ${\text{YSn}}_{3}$ is a superconductor with a s…
Based on transformation optics theory, we designed a chirality switching device, such that an object hidden inside would exhibit a reversed chirality (i.e., from left-handedness to right-handedness) for an observer at the far field. Distinct from a perfect mirror which also creates a chirality-reversed image, our devi…
To optimize the blood biocompatibility of poly(lactide-coglycolide) (PLGA), lipid-like diblock copolymer poly(DL-lactide)-block-poly(2-methacryloyloxyethyl phosphorylcholine) (PLA-b-PMPC) was employed as a surface-modifying additive. The blends of PLGA and PLA-b-PMPC coated poly(ethylene terephthalate) membranes were…
In the current work we report on the synthesis of LiKB(4)O(7), Li(2)B(6)O(10), and LiCsB(6)O(10) borate glasses. The results for their piezo-optic, acousto-optic, acoustic, elastic, refractive, optical transmission, and optical resistance properties are also presented. It is shown that some of these glasses represent…
In the foreseeable future, the MI field could greatly assist neuroradiologists. Reporter molecules provide information on specific molecular or cellular events that could not only aid diagnosis but potentially differentiate stages of disorders and treatments. To accomplish this, reporter molecules literally need to pa…

Pressure and temperature dependence of the electronic structure of superconducting (SC) ${\text{CeFeAsO}}_{1\ensuremath{-}y}$ and non-SC ${\text{CeFeAsO}}_{1\ensuremath{-}y}$ have been investigated using two complementary hard x-ray spectroscopic probes at the $\text{Ce}\text{ }{L}_{3}$ edge, partial fluorescence yiel…
We present a computationally efficient semi-empirical method, based on standard first-principles techniques and the so-called virtual crystal approximation, for determining the average atomic structure of crystals with substitutional disorder. We show that, making use of a minimal amount of experimental information, i…
Cyclisierung im Dreierpack: Mit einer dreifachen Pictet-Spengler-Reaktion als Schlüsselschritt wurden Triazacoronen-Derivate in vier Stufen ausgehend von Veratrol synthetisiert. Die Produkte haben interessante photophysikalische und elektronische Eigenschaften und sind thermisch beständig sowie löslich, sodass sie vie…
Abstract We report a facile way of preparing microfluidic channels filled with electrospun functional fibers. Patterned elastic molds were in tight contact with electrospun fiber mats without any leak of the analyte solution. As an example of the simple devices, we demonstrated a microfluidic protein chip selectively…
The reactions of copper(II) salts, 1,3-bis(dimethylamino)-2-propanol (bdmapH) or 1,3-bis(amino)-2-propanol (bapH) and [(Tp)Fe(CN)(3)](-) (Tp = tris(pyrazolyl)hydroborate) gave four mixed-bridged heterometallic one-dimensional (1D) coordination polymers, {[(Tp)(2)Fe(2)(CN)(6)(OAc)(bdmap)Cu(2)(H(2)O)]·2H(2)O}(n) (1, HOA…

Abstract Tissue engineering is a promising interdisciplinary scientific field of regenerative medicine. Aiming at the structural and functional restoration of damaged tissues and organs, it possesses a role of significant socioeconomical impact. In the course towards the ultimate goal of artificially constructed natur…
Submicron-structured (Bi 0.5 Na 0.5 ) 0.94 Ba 0.06 TiO 3 (BNBT6) ceramics were obtained from nanometric powder synthesized by sol–gel auto-combustion at 500 °C. Hot-pressing at low temperatures and a combination of this with recrystallization, still moderate in order to reduce the loss of volatile elements, have been…
${\text{KCrF}}_{3}$ represents another prototypical orbital-ordered perovskite, where ${\text{Cr}}^{2+}$ possesses the same electronic configuration of $3{d}^{4}$ as that of strongly Jahn-Teller distorted ${\text{Mn}}^{3+}$ in many colossal magnetoresistance manganites. The crystal and magnetic structures of ${\text{K…
An innovative unimolecular precursor structure based on cadmium-bis(benzylthiolates), Cd(SBz) 2, has been devised for the preparation of polymer/CdS nanocomposite materials through a simple and inexpensive synthetic route. Cd(SBz) 2 and [Cd(SBz) 2 ] 2 ·MI, MI being methyl imidazole, dispersed in a polymer matrix have…
We report the results of x-ray photon correlation spectroscopy (XPCS) experiments on multilayers of a photosensitive azo-polymer which can be softened by photoisomerization. Time correlation functions have been measured at different temperatures and momentum transfers (q) and under different illumination conditions (d…
