In this work we have studied the dielectric properties of five unsymmetrical azomethine (A1−A5) liquid crystals prepared from different aldehydes or obtained from various amines. The effects of rod length and type of terminal chains on the thermal and mesomorphic behaviours were investigated by dielectric spectroscopy…
Fluorescence resonance energy transfer (FRET) is an important photophysical mechanism which finds many applications in biophotonics, particularly in biological sensing and imaging. It is well known, there are two major factors that determine the efficiency of FRET. One is the distance between the donor and the accepto…

Abstract BACKGROUND: The main objective of this work was to evaluate the parametric sensitivity of model parameters of clavulanic acid (CA) adsorption in a stirred‐tank reactor using zeolites. The system sensitivity was evaluated in terms of mass transfer and hydrodynamic parameters using two methodologies. First, the…
Selbstassoziate der Titelverbindung 1 ändern sich von definierten Bändern über Vesikel zu Körben (siehe Bild) bei Verringerung der Konzentration in Tetrahydrofuran. Elektronenmikroskopie zeigte eine einzigartige selbstorganisierte Struktur: Körbe werden von gebogenen und eingewickelten nanometerdünnen Bändern gebildet…
Abstract A new method for the preparation of metal–polymer composite materials is described. This new approach of doping of metals is based on the thermolysis of a zero‐valent complex. Specifically, several polymer@Fe‐composite powders were prepared and fully characterized. Iron doped with polydimethylsiloxane showed…
Ultrasound process parameters had infl uence on the temperature increase as result of wave propagation throughout medium. Cavitation as the most accepted mechanism is based on the implosion of bubbles in surrounding media (Bosiljkov et al., 2011; Brncic et al., 2010; Price et al., 2010; Thiemann et al., 2011). Effi ci…
We report on the structural, spectroscopic and radiative emission characteristics of Eu-doped BaTiO3 (BT) nanosystem as compared to the pure BT system. The structural analysis was performed by X-ray diffraction (XRD) studies where the nanoscale BT sample exhibits a perovskite structure with most intense peak along (1…
Abstract Molecular tweezers built from sawhorse‐type dinuclearruthenium units and carboxyphenyl porphyrin derivatives{5‐(4‐carboxyphenyl)‐10,15,20‐triphenyl‐21H,23H‐porphyrin,[5‐(4‐carboxyphenyl)‐10,15,20‐triphenylporphyrin]zinc, 5,10‐bis(4‐carboxyphenyl)‐15,20‐diphenyl‐21H,23H‐porphyrin, and [5,10‐bis(4‐carboxyphenyl…
We present a theoretical study of a model heterostructure for a Mott insulator sandwiched between two band insulators, motivated by SrTiO${}_{3}$/LaTiO${}_{3}$. Particular emphasis is given on the interplay between magnetism and inhomogeneous charge distributions. Our mean-field analysis of the generalized Hubbard mod…
We have developed and characterized efficient caged compounds of the neurotransmitter octopamine. For derivatization, we introduced [6-bromo-8-(diethylaminomethyl)-7-hydroxycoumarin-4-yl]methoxycarbonyl (DBHCMOC) and {6-bromo-7-hydroxy-8-[(piperazin-1-yl)methyl]coumarin-4-yl}methoxycarbonyl (PBHCMOC) moieties as novel…
Abstract This work evaluates the influence of a radiopaque reinforcement, barium sulfate (BaSO4), on the mechanical, rheological and thermal properties of polyoxymethylene (POM). Nanocomposites of POM containing spherical nanoparticles of BaSO4 (0, 1, 2, 3 phr) were obtained by melt extrusion in a twin-screw equipment…
We report the magnetic structure of TaFe${}_{1+y}$Te${}_{3}$ single crystals by means of neutron diffraction measurements. TaFe${}_{1+y}$Te${}_{3}$ possesses a layered structure with a formation of two-leg zigzag ladders along the $b$ axis. We find that TaFe${}_{1+y}$Te${}_{3}$ undergoes an antiferromagnetic transitio…
Managing high heat flux is one of the greatest technical challenges the integrated circuit (IC) industry is facing because the rising temperature limits device minimization and decreases its lifetime. In this paper, we report the characterization of the cooling effect of nanoscale Bi2Te3/Sb2Te3 multilayered thin films…
Abstract A homologous series of hyperbranched polymers (HBPs) was prepared following a well‐defined method and their formation in a polymeric form bearing different extents of branching with amine functional groups at the terminals was verified using different techniques such as Fourier Transform Infrared, 1H Nuclear…
Crystal architectures delimited by sinuous boundaries and exhibiting complex hierarchical structures are a common product of natural biomineralization. However, related forms can also be generated in purely inorganic environments, as exemplified by the existence of so-called “silica-carbonate biomorphs”. These peculia…
Abstract In this article, polyimide (PI) films were fabricated via the three‐step method including the reactions of condensation polymerization, chemical imidization, and thermal imidization. In comparison with the conventional two‐step method to produce PI films, there was an additional step in the present method, i.…
Abstract Anti‐counterfeiting technologies are desired to protect products far away from the violation of dummy, fake and shoddy goods. The phosphor of (Y,Gd)VO4:Bi3+,Eu3+ was synthesized for the application of this purpose. Its photoluminescence was investigated by exciting with different wavelengths at variant temper…
In this work, we explored the formation processes of suspended hybrid thin films of thiol-capped Au nanoparticles (AuNPs) inside metal oxide tubular structures. We found that a balance between in-film interactions of the AuNPs and boundary interactions with metal oxides is a key in making these special organic-inorgan…
