A diazonium salt-derived organoimido hexamolybdate was synthesized and directly covalently immobilized on Si surfaces using diazonium chemistry to form both monolayers and multilayers. These monolayers and multilayers were characterized by ellipsometry, X-ray photoelectron spectroscopy (XPS), and electrochemical analy…
Purpose The purpose of this paper is to evaluate the corrosion inhibition potential of Calotropis procera in sulphuric acid medium on mild steel with a view to developing green corrosion inhibitors. Design/methodology/approach Extract of the C. procera was studied for its corrosion inhibitive effect by weight loss, el…
The influence of the substrate polarity (Zn polar or O polar) on the structural and optical properties of homoepitaxial ZnO epilayers grown by chemical vapor deposition is investigated. The polarity of the epilayer is controlled by the substrate polarity as shown by high-resolution transmission electron microscopy (TE…
Polypyrrole (PPY)/SrFe12O19 composites with tunable electrical and magnetic properties were synthesized by in situ polymerization of pyrrole in the presence of SrFe12O19 particles. The structure of PPY/SrFe12O19 composites was characterized by means of Fourier transform infrared spectroscopy and X-ray diffraction. Tra…

Abstract Drang nach draußen : Mit Cyclodextrinen (CDs) an photochemisch spaltbaren Linkern beschichtete mesoporöse Siliciumoxidnanopartikel entlassen eingeschlossene Spezies unter Bestrahlung und gehen einen Sol‐Gel‐Übergang ein, der durch molekulare Erkennung ausgelöst wird (siehe Bild). Unter UV‐Bestrahlung werden G…
Most porous anodic alumina (PAA) or anodic aluminum oxide (AAO) films are fabricated using the potentiostatic method from high-purity (99.999%) aluminum films at a low temperature of approximately 0-10 degrees C to avoid dissolution effects at room temperature (RT). In this study, we have demonstrated the fabrication…
Among the plethora of parameters controlling the stability and structures of lanthanide coordination complexes, it is often difficult to decipher their relative importance in the global complexation processes. The combination of the bond valence method (for analyzing solid state structures) with the thermodynamic site…
Abstract A hybrid approach has been adopted by using a combination of colloidal graphite (CG) as a conducting filler, 5‐lithium sulfoisophthalic (LiSIPA) acid as a dopant, and polyaniline (PANI) as a matrix to prepare LiSIPA doped PANI–CG composites. The thermal stability (∼300°C) and electrical conductivity (67.4 S/c…
The purpose of this study was to characterize the properties in vitro, i.e. release, degradation, hemolytic potential and anticancer activity, and in vivo disposition of all-trans-retinoic acid (ATRA) in rats after administration of ATRA-loaded micelle-like nanoparticles. The amphiphilic block copolymers consisted of…
For the high temperature operation of diamond for high power devices, a new Ru/diamond material contact was proposed for the first time for thermally stable Schottky barrier diode (SBD). This contact showed very good Schottky properties, with the further advantages of low resistivity, high chemical stability and very…
A smectic liquid crystal (LC) containing a rigid biphenyl group and semifluorinated chains exhibits a high density of toric focal conic domains (TFCDs) arranged in an ordered array when confined within a microchannel. The formation of the TFCDs is strongly influenced by the width (W) and depth (h) of the confined micr…
The high-brilliance X-ray beams from undulator sources at third-generation synchrotron facilities are excellent tools for solving crystal structures of important and challenging biological macromolecules and complexes. However, many of the most important structural targets yield crystals that are too small or too inho…
We report the synthesis and characterization of DNA-grafted poly(N-isopropylacrylamide) (PNIPAM) micelles, their assembly into multilayered thin films, and the subsequent generation and poly(ethylene glycol) (PEG) functionalization of DNA-PNIPAM microcapsules. Multilayer films were assembled by sequentially depositing…
A supercooled liquid generally exhibits marked shear-thinning behavior, but its detailed mechanism remains elusive. Here we study the dynamics of structural rearrangements in supercooled liquids under shear, using two-dimensional (2D) molecular dynamics simulation. To elucidate the relationship between heterogeneous d…
Abstract A good balance: Oil‐soluble CdTe/CdS core/shell quantum dots (QDs) that emit in the visible and near‐infrared spectral regions with quantum yields up to 92 % (see figure) are prepared by balancing the coordinating capacity and the activation effect of selected surfactants. magnified image An effective shell‐c…
We present a polarization-independent metamaterial design for the construction of electrically tunable terahertz (THz) devices. The implemented structure consists of an array of gold crosses fabricated on top of an n-doped gallium arsenide (GaAs) layer. Utilizing THz time-domain spectroscopy, we show that the electric…
The effect of the coating polymer poly(N-vinyl-pyrrolidone) (PVP) on the protein adsorption, phagocytosis, and pharmacokinetics of poly(D,L-lactide)-based nanoparticles was evaluated in vitro and in vivo. Control poly(ethylene glycol) (PEG)-coated nanoparticles were included for comparison. While no difference between…

Due to the weak spin-orbit interaction and the peculiar relativistic dispersion in graphene, there are exciting proposals to build spin qubits in graphene nanoribbons with armchair boundaries. However, the mutual interactions between electrons are neglected in most studies so far and thus motivate us to investigate th…
