It is well known that molybdenum and silicon is the combination with the highest EUV reflectivity of two-component multilayers in the wavelength range lambda=12.5-20nm. Using the magnetron sputter deposition method multilayers with reflectivities of typically 69% can be prepared. A further increase to R=70% was demons…
The ability to predict the crystal structure of a material, given its constituent atoms, is one of the most fundamental problems in materials research. There exist a number of empirical methods which make predictions by clustering existing experimental data, generally using a few simple physical parameters. Although P…
The photo-induced magnetization density of the photoswitchable $[{\mathrm{Fe}(\mathrm{ptz})}_{6}]({\mathrm{BF}}_{4}{)}_{2}$ $(\mathrm{ptz}=1\ensuremath{-}\mathrm{p}\mathrm{r}\mathrm{o}\mathrm{p}\mathrm{y}\mathrm{l}\mathrm{t}\mathrm{e}\mathrm{t}\mathrm{r}\mathrm{a}\ensuremath{-}\mathrm{z}\mathrm{o}\mathrm{l}\mathrm{e})…
Abstract Polyethylene (PE)/clay nanocomposites were prepared directly from Na + montmorillonite by a melt intercalation technique, using hexadecyl trimethyl ammonium bromide (C16) as a reactive compatibilizer. Three other polymer–clay nanocomposites were also prepared by this new technique. Their structures were chara…
Abstract Oligoesters present in poly(ethylene terephthalate) fibers are commonly extracted from the fiber during processing, such as aqueous‐based dyeing. Aqueous, insoluble oligoesters, particularly cyclic trimers that precipitate on processing machinery and on the fiber surface are difficult to remove under benign c…
Radiation effects in components and materials will be one of the most serious technological issues in nuclear fusion systems realizing burning-plasmas. Especially, diagnostic components, which should play a crucial role in controlling plasmas and understanding the physics of burning-plasmas, will be exposed to high-fl…
Abstract A series of poly(acrylamide‐ co ‐4‐vinylpyridine) hydrogels having varied acrylamide/4‐vinylpyridine content and different crosslink ratios of N , N ′‐methylene‐bisacrylamide was prepared by using solution polymerization. The prepared hydrogel polymers were characterized by their elemental analysis, infrared…
Three divalent ytterbium complexes supported by a β -diketiminate ligand were synthesized for the first time. The mixed-ligand ytterbium chlorides (CH 3 C 5 H 4 )[(DIPPh) 2 nacnac]YbCl ( 1 ), (C 9 H 7 )[(DIPPh) 2 nacnac]YbCl ( 2 ), and (ArO)[(DIPPh) 2 nacnac]YbCl(THF) ( 3 ) ((DIPPh) 2 nacnac = N, N -diisopropylphenyl-…
Abstract The influence of the preparation procedure on the thermal and mechanical properties of linear low‐density polyethylene (LLDPE)– and LDPE–oxidized wax blends was investigated. It was found that mechanically mixed blends show reduced thermal stability as well as ultimate mechanical properties (stress and strain…
Abstract The compatibilization of syndiotactic polystyrene (sPS)/polyamide 6 (PA‐6) blends with maleic anhydride grafted syndiotactic polystyrene (sPS‐ g ‐MA) as a reactive compatibilizer was investigated. The sPS/PA‐6 blends were in situ compatibilized by a reaction between the maleic anhydride (MA) of sPS‐ g ‐MA and…
Abstract The crosslinking effects on the mechanical and electrical properties of a conducting copolymer obtained by grafting polyaniline on a carboxylated polyurethane were investigated. The synthesis and characterization of the polyurethane–polyaniline copolymer (PEUAPAN) were previously reported. The crosslinking pr…
La–Sb–Mn–O compounds have been prepared by the solid-state reaction of La 2 O 3 , Sb 2 O 3 and MnCO 3 . The materials have a perovskite structure and exhibit the colossal magnetoresistance (CMR) effect, and the maximum magnetoresistance ratio could reach as high as 60% (at 225 K under 5 T) for La 0.9 Sb 0.1 MnO 3 . Th…
Single crystals of the chemically and electrochemically delithiated Li x MnO 2 ( x < 0.1) have been successfully synthesized from the parent orthorhombic LiMnO 2 single crystals. A single-crystal X-ray diffraction study revealed that the average structure of Li x MnO 2 was the disordered rocksalt-type with the space g…
Structure maps have always held out the allure of being useful guides in materials design. A novel method for predicting candidate structure types demonstrates that the Pettifor maps for binary compounds are surprisingly predictive and offers a natural way for extending the predictive power of the maps to higher multi…
The A 1 -symmetry Raman spectra of berlinite in a broad temperature range, encompassing the α–β phase transition, are reported. The temperature dependence of the lattice mode parameters is presented, particularly concerning the 'soft' mode at ∼220 cm −1 , which exhibits a complex behaviour in the α phase. This is acco…
Ni/diamond Schottky diodes were fabricated on boron-doped homoepitaxial diamond films. Temperature dependence on electrical characteristics of the Schottky diodes was investigated in a temperature range 148 to ∼448 K. The current–voltage characteristics of the diodes show excellent rectification behavior. Temperature…
The evolution of the nanosecond dynamics of the core tryptophan, Trp53, of barstar has been monitored during the induction of collapse and structure formation in the denatured D form at pH 12, by addition of increasing concentrations of the stabilizing salt Na(2)SO(4). Time-resolved fluorescence methods have been used…
Abstract Tire rubber particles were mixed randomly with short sisal fibers and hot pressed. Sisal fibers were used as received, mercerized, and mercerized/acetylated. The fibers were characterized by scanning electron microscopy (SEM), thermal gravimetry analysis (TGA), infrared spectroscopy (FTIR), water sorption, an…
DOTA-tetraamide ligands having extended phenol or pyridine substituents have been synthesized. The (5)D(0) --> (7)F(J) deltaJ = 1 and 2 emission bands in the corresponding europium(III) complexes differ in their sensitivity to solution pH. This offers the potential for developing pH responsive probes for in vivo imagi…
We have performed Monte Carlo simulations to study the behavior of a single nanoparticle and a single homopolymer chain in ordered structures of diblock copolymers. Our results show that the microphase-separated copolymers can be used to position nanoparticles or homopolymers according to their interactions with the t…
