Achyrocline satureioides (Lam.) DC., Asteraceae, is a herbal specie widely used in folk medicine in the south of Brazil, Uruguay, Argentina and Paraguay. The technological characteristics of an Achyrocline satureioides spray dried extract powder, produced in semi-industrial scale, as well as the feasibility of the gra…
Wear characteristics of Al6061 composites, reinforced with short NiTi fibers, were investigated. The NiTi/Al6061 composite samples were fabricated using pressure-assisted sintering process in ambient air where the NiTi fibers are aligned unidirectional in the Al matrix. In addition, NiTi/Al6061 composite with 5 wt % S…
Recent standardization developments within the European Union relating to masonry and block systems now allow calculation of thermal performance to be undertaken based on the block configuration and reliable values of the material thermal conductivity. In general, to attain the optimum thermal resistance of a block a…
A trinuclear assembly of two (η(2)-dppe)(η(5)-C(5)Me(5))FeC≡C(4-Py) (Py = pyridyl) metalloligands apically coordinated to a ruthenium(II) tetramesitylporphyrin is demonstrated to behave as a molecular wire in the monooxidized state.
Dank seiner ungewöhnlichen elektronischen Eigenschaften findet Graphen seit einigen Jahren große Beachtung. Wenig bekannt ist, dass die Forschung auf diesem Gebiet wesentlich weiter zurückreicht: So reduzierten H.-P. Boehm et al. bereits Anfang der 1960er Graphitoxid unter Bildung dünner Filme, die man heute wegen ihr…
Abstract A novel copolymer of vinylidene cyanide (VCN) and 2,2,2‐trifluoroethyl methacrylate (MATRIF) was synthesized by bulk free radical process in a 52% yield from an equimolar comonomer feed. The copolymer's composition and microstructure were analyzed by FTIR, 1 H‐ and 13 C‐NMR spectroscopy, SEC, and elemental an…
The doping dependence of spin excitations in $\text{Ba}{({\text{Fe}}_{1\ensuremath{-}x}{\text{Co}}_{x})}_{2}{\text{As}}_{2}$ is studied based on a phenomenological two-orbital model under the random-phase approximation. We adopt this model because of its ability to fit the doping evolution of the Fermi surfaces and th…
Microbial depolymerization processes of exogenous type are studied for biodegradation of polyethylene glycol. The time factor of a degradation rate is the microbial population which grows on degraded monomer units as the carbon source. Numerical simulation shows that our model is of practical use.

Abstract Iron oxide nanoparticles (NPs) are frequently employed in biomedical research as magnetic resonance (MR) contrast agents where high intracellular levels are required to clearly depict signal alterations. To date, the toxicity and applicability of these particles have not been completely unraveled. Here, we sh…
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…
