We investigated the orbital and antiferromagnetic ordering behaviors of the half-doped bilayer manganite ${\mathrm{La}}_{2\ensuremath{-}2x}{\mathrm{Sr}}_{1+2x}{\mathrm{Mn}}_{2}{\mathrm{O}}_{7}$ ($x\ensuremath{\simeq}0.5$) by using Mn ${L}_{2,3}$-edge resonant soft x-ray scattering. Resonant soft x-ray scattering revea…
In this paper we present a novel technological approach for the fabrication of multilevel gratings in the resonance domain. A coded chromium mask is used to avoid alignment errors in electron beam lithography, which typically occur within the standard multistep binary micro-optics technology. The lateral features of a…
Doped SbTe phase change (PRAM) line cells produced by e-beam lithography were cycled 100 million times. During cell cycling the evolution of many cell properties were monitored, in particular the crystalline and amorphous resistance, amorphous resistance drift exponent, time-dependent threshold voltage, threshold volt…
Abstract In this paper, a modular pathway towards the synthesis of new specific MRI contrast agents and their luminescent analogues is described. Using two azide‐bearing probes, 3β‐deoxycholic acid and c RGDfK(N 3 ), we performed a “click” reaction with an alkyne‐bearing 1,4,7,10‐tetraazacyclododecane‐1,4,7,10‐tetraac…
We study structures which can bear loads, "bridges", in particulate packings. To investigate the relationship between bridges and gravity, we experimentally determine bridge statistics in colloidal packings. We vary the effective magnitude and direction of gravity, volume fraction, and interactions, and find that the…
Reaction of the aluminum hydroxide LAl(OH)[C(Ph)CH(Ph)] (1, L = HC[(CMe)(NAr)](2), Ar = 2,6-iPr(2)C(6)H(3)) with Y(CH(2)SiMe(3))(3)(THF)(2) yielded the oxo-bridged heterobimetallic yttrium dialkyl complex LAl[C(Ph)CH(Ph)](μ-O)Y(CH(2)SiMe(3))(2)(THF)(2) (2). Alkane elimination reaction of 2 with 2-(imino)pyrrole [NN]H…
It is best-known in the nanoscience community that anodic aluminum oxide (AAO) membrane templates have been widely employed in the synthesis of one-dimensional nanomaterials, such as nanowires, nanorods, and nanotubes with cylindrical shapes. In this work, however, we demonstrate that AAO nanochannels can be used to g…
The conventional protocols for in solution or in gel protein digestion require many steps and long reaction times. The use of trypsin immobilized onto solid supports has recently captured the attention of many research groups, because these systems can speed-up protein digestion significantly. The utilization of new m…
The functionalized polypropylene-based hydrophobic Accurel products were probed for their use in sugar decolorization. The pore distribution of Accurel products falls between the macroporous and mesoporous domains. Their specific surface areas are typically in the range S BET = 20–35 m 2 /g. Commercial decolorizing ac…
In order to understand the mechanism of coercivity (Hc) of Nd-Fe-B magnets, we have investigated the effect of thermal annealing treatment on Nd-Fe-B thin films with Nd-Cu alloy cap layers. A substantial enhancement of Hc from 19.0 kOe (1512 kAm−1) to 26.1 kOe (2078 kAm−1) was obtained for the Nd-Fe-B/Nd36Cu64 films a…
Thin-film composites of polymethylmethacrylate (PMMA) with multiwalled carbon nanotubes (MWCNTs) and corona based electrostatically functionalized multiwalled carbon nanotubes (f-MWCNTs) were drop cast for organic vapor detection. The electrical responses of the composite films were investigated for different organic…

A procedure has been developed to directly measure the adiabatic temperature change of amorphous melt-spun Fe-based ribbons displaying attractive room temperature magnetocaloric properties. Polycrystalline Gd ribbons are used as a reference material to compensate for the contribution of the sample holder to the experi…
Composite BaO/MgO nanoparticles have been prepared by chemical vapor synthesis and subsequent annealing in controlled gas atmospheres. High resolution transmission electron microscopy and X-ray diffraction reveal that a part of the obtained nanoparticles can be characterized as support particles with hemispherical BaO…
Bentonite clay is part of the Swedish KBS-3 design of final repositories for high level radioactive waste. Wyoming bentonite with the commercial name MX-80 (American Colloid Co) has long been the reference for buffer material in the KBS-3 concept. Extending the knowledge base of alternative buffer materials will make…
The published secondary electron yield (SEY) data, δ = f(E°), are characterized by a poor level of agreement, rarely more than 25% and lower for a common element such as Al. Some possible sources of discrepancies are related to sample preparation, leading to differences in surface composition (contamination and oxidat…
Abstract The effect of rice husk powder (RHP) on the tensile properties, swelling, water absorption, and morphology of polypropylene (PP)/[recycled acrylonitrile‐butadiene rubber (NBRr)]/RHP composites was studied. Composites containing 0 to 30 parts of RHP per hundred parts of resin were prepared by using a Haake Rhe…
Silicon dioxide nanoparticles (SiO(2) NPs) have attracted increasing interest as nanovehicles for delivering drugs, genes and bio-active molecules into cells. However, it is still unknown whether SiO(2) NPs could cause side-effects to normal cells. In the present study, human lung fibroblasts (HFL-Is) were directly ex…
Dielectric materials exhibiting high dielectric constants play critical roles in a wide range of applications from microchip energy storage embedded capacitors for implantable biomedical devices to energy storage capacitors for a new generation of renewable energy generation/storage systems. Instead of searching for n…
