We have synthesized a new macrocyclic ligand, N,N'-Bis[(6-carboxy-2-pyridyl)methyl]-1,7-diaza-12-crown-4 (H 2bp12c4), designed for complexation of lanthanide ions in aqueous solution. The X-ray crystal structure of the Gd (III) complex shows that the metal ion is directly bound to the eight donor atoms of the bp12c4 l…
Rational assembly of nanoparticles is of vital importance for exploring fundamental electronic and optical properties and for constructing novel nanoscale devices. Through controlling aggregation kinetics, dimers and trimers of gold nanoparticles were generated and encapsulated with polymer by using a one-pot synthesi…
In this report, for the first time, a planar chiral photoresponsive compound has been employed in commercially available nematic liquid crystals to achieve phototunable reflection colors. We designed an azobenzenophane compound having conformational restriction on the free rotation of naphthalene moiety to impose an e…
We show that misfit strain originated from the film-substrate lattice mismatch strongly increases the value of the quadratic magnetoelectric coupling. The giant magnetoelectric coupling, size effects and misfit strain cause strong changes of ferroic films phase diagrams at zero external magnetic and electric fields, i…
Comments are made concerning the recent use of adjectives to describe solid surfaces that exhibit anomalously high water contact angle values. We suggest that the meaning of the word hydrophobic be resolved before it is modified, for example, to superhydrophobic and further modified, for example, to sticky superhydrop…
In this work, we investigate protein adsorption from single protein solutions and complex media such as 100% blood serum and plasma onto poly(sulfobetaine methacrylate) (polySBMA)-grafted surfaces via atom transfer radical polymerization (ATRP) at varying film thicknesses. It is interesting to observe that protein ads…
The creation of a suitable inorganic colloidal nanocrystal ink for use in a scalable coating process is a key step in the development of low-cost solar cells. Here, we present a facile solution synthesis of chalcopyrite CuInSe 2 nanocrystals and demonstrate that inks based on these nanocrystals can be used to create s…
PDF | Cerâmicas à base de cromitas de lantânio são os principais materiais usados em interconectores de células a combustível de óxido sólido. O objetivo deste trabalho é investigar e caracterizar as relações entre métodos de preparação de pós e o desenvolvimento microestrutural destes materiais. Cromitas de lantânio…
NiMn alloys alloyed with aluminum in a wide range of temperatures and compositions have been investigated by resistivity measurements, electron diffraction, and X-ray diffraction. It is found that the martensitic transformation temperature decreases with an increase in the aluminum content in an alloy. The martensitic…
Liquid metals have received a renewed interest in fusion research due to the advantages that these materials could offer to overcome the erosion problem of plasma facing components presently used in large-size fusion devices. In ISTTOK tokamak, the plasma-liquid gallium jet interaction is currently being studied. One…
Abstract Um das Ziel zu erreichen, Stahlzahnräder hinsichtlich Tragfähigkeit und Verschleiß zu optimieren, wurden in diesem Vorhaben Beschichtungen erprobt. Im Rahmen von Vorarbeiten wurden verschiedene Schichtsysteme numerisch mit der Software ELASTICA® auf ihre Eignung geprüft. Dabei wurden die Eigenschaften der Sch…
The behavior of soft mode range with respect to the temperature width of smectic A (Sm A) phase has been studied in four different ferroelectric liquid crystal (FLC) materials in the frequency range 10Hz–10MHz. The studies have been carried out in a planarly well aligned cells at different temperatures and different b…
The effect of calcination temperatures (1000-1400 oC) on the phase formation and microstructure of barium strontium zirconate titanate [(Ba0.25Sr0.75)(Zr0.75Ti0.25)O3 ; BSZT] powders were investigated. BSZT powders were prepared and compared by the solid state reaction method and the combustion technique. The higher c…
From the viewpoints of plasma control and radiation safety, tritium retention in deposition layers is an important problem. In this study, deposition layers from type 316 stainless steel were formed by a sputtering method using hydrogen RF plasma at three different temperatures. The behavior of hydrogen release from t…
An investigation was conducted to predict the failure strength response of IG-100 nuclear grade graphite exposed to multiaxial stresses. As part of this effort, a review of failure criteria accounting for the stochastic strength response is provided. The experimental work was performed in the early 1990s at the Oak Ri…
We investigated the effects of Cr element substitution on thermal stability of magnetic flux and oxidation resistance of SmFeN compounds by X-ray diffraction (XRD), thermogravimetry analysis (TG), and flux aging loss measurement methods. We found that with increases in Cr substitution, the irreversible flux losses of…
The linting propensity of a woven cellulosic substrate is investigated as a function of substrate characteristics and of different parameters in the test environment. The results from the linting propensity tests parallel those observed in liquid—solid extraction processes, where solutes are extracted from a matrix of…
The curves of intracenter luminescence decay for Mn2+ ions in the Cd0.5Mn0.5Te semiconductor solid solution, obtained in a low-temperature experiment, have been simulated by the Monte Carlo method. The features of the kinetics of the 2-eV band in the time interval where significant nonexponentiality of relaxation at d…

A fuel cell-supercapacitor hybrid power supply for portable applications is designed. To ensure system level simulation, each component is accurately modelled and simulation results are reported. A digital still camera is selected as specific load device, although the choice of a specific application does not influenc…
