This study synthesized a europium (Eu(3+)) complex Eu(DBM)(3)Cl-MIP (DBM = dibenzoyl methane; Cl-MIP = 2-(2-chlorophenyl)-1-methyl-1H-imidazo[4,5-f][1,10]phenanthroline) dispersed in a benzyl methacrylate (BMA) monomer and treated with ultraviolet (UV) light for polymerization. Spectral results showed that the europiu…
More and more applications of nanomaterials have been achieved in the biomedicine field. Numerous nanomedical devices, such as bone grafts with nano-hydroxyapatite and the silver-based anti-bacteria products, have been developed and have been trying to enter into the Chinese market. The State Food and Drug Administrat…
The stable small Ag seeds (size in diameter < 10 nm) were obtained in the presence of inositol hexakisphosphoric (IP₆) micelles. Then Ag-Au bimetallic nanoparticles were synthesized through a replacement reaction with the rapid interdiffusion process between such small Ag seeds in nanoclusters and HAuCl₄. Adjusting th…
We present a graphene resist interlacing process (GRIP) to sandwich graphene between polymer lines in a cloth-like fashion, making it more accessible for experiments and applications. We demonstrate the handling of large-area graphene in this way. Here, GRIP is used to fabricate supports for transmission electron micr…

The existence of a strong hydrogen bond between two molecules of an (alkoxoimino)pyridinemanganese(I) complex induces their dimerization and the formation of a metallamacrocycle. The expected intramolecular attack of the alkoxo moiety is disfavored.
The ability of bacteria to express inhibitor-resistant (IR) β-lactamases is stimulating the development of novel inhibitors of these enzymes. The 2'β-glutaroxypenicillinate sulfone, SA2-13, was previously designed to enhance the stabilization of the deacylation-refractory, trans-enamine inhibitory intermediate. To tes…
Following a loss of coolant accident in a light water reactor, reflooding of the core to quench overheating fuel is urgent. The process of quenching hot metal with liquid water has been much studied, in large part because of its great importance in this context. There is good experimental evidence such as quenching oc…
Formation energies and energy levels of various neutral and charged defects in bulk rhombohedral LaAlO3 are calculated numerically in different equilibrium conditions under different oxygen partial pressures, using first-principles plane-wave calculations. The roles of such defects in electrical properties of LaAlO3 a…
This study presents molecular dynamics simulations on the segregation of binary mixtures in a high-velocity rotating drum. Depending on the ratio between the particle radius and density, similarities to the Brazil-nut effect and its reverse form are shown in the ringlike spin segregation patterns in radial direction.…
We use differential scanning calorimetry (DSC) to study the properties of DNA films, made of oriented fibers, heated above the thermal denaturation temperature of the double helical form. The films show glassy properties that we investigate in two series of experiments, a slow cooling at different rates followed by a…
This study has developed a new material for indoor formaldehyde control, room‐temperature catalytic oxidation (RCO) and RCO‐coated media. In order to optimize the adsorption capacity of RCO material on indoor formaldehyde, four impacting factors, including active/assistant component ratio, ingredient ratio (KMnO4/MnSO…
Abstract This article examines several new methods for compounding nanocomposite materials by twin screw extrusion that use supercritical CO2 as a processing aid to produce more highly exfoliated polyolefin‐layered silicate nanocomposites than conventional melt intercalation. These methods varied the manner in which t…
We present an analytical model for the optical emission of a two-dimensional source in a flexible organic light-emitting diode formation with arbitrary curvature. The formulation rigorously produces closed-form analytical expressions which clearly relate the emission pattern and the device configuration, in particular…
Abstract In this study, thermoplastic polyurethanes (TPUs) were obtained in a torque rheometer (an instrumented batch mixer) at 70, 80, and 90°C, and the thermal properties were studied by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). DSC results showed that the glass transition tempera…
The reactive extraction of Bixa orellana seed pigment norbixin with cationic carrier Aliquat‐336 (QCl) in a two phase system has been studied. A raw alkali extract of Bixa orellana pigments in 0.5% sodium hydroxide solution is used as aqueous phase and Aliquat‐336 dissolved in hexane as solvent is used as the organic…
We present the examination of light induced behavior of spin-crossover compounds. We focus on the switching phenomena between low-spin and high-spin states of the system. The connection between the Ising-like model and the macroscopic evolution equation has been analyzed. By means of numerical simulations, we found th…
The degenerate parabolic equation u t + ∂ x [u 3(u xxx + u x − sin x)] = 0 models the evolution of a thin liquid film on a stationary horizontal cylinder. It is shown here that for each mass there is a unique steady state, given by a droplet hanging from the bottom of the cylinder that meets the dry region with zero c…
Chemischer Wasserstoffspeicher: Rechnungen zufolge wird die Dehydrierung von auf Bornitrid-Nanoröhren (BNNTs) chemisorbierten Wasserstoffatomen durch geeignete Reagentien unter zeitgleichem Protonen- und Hydridtransfer ausgelöst (siehe Bild). Für die Reduktion von Formaldehyd zu Methanol durch Wasserstoffatome, die au…
Current knowledge on the reaction whereby a protein acquires its native three-dimensional structure was obtained by and large through characterization of the folding mechanism of simple systems. Given the multiplicity of amino acid sequences and unique folds, it is not so easy, however, to draw general rules by compar…
