Field and Current Driven Magnetic Domain Wall Motion in Disordered A1-FePt Nanowires
Arc-shaped magnetic FePt nanowires (10nm thick, 375nm wide) displaying in-plane anisotropy were fabricated. A vortex domain wall was formed in the middle of the arc after in-plane saturation in a field perpendicular to the wire. Translational domain wall propagation was observed at a field of 40 Oe applied parallel to…
Design of a meso-structured Pd/NiO catalyst for highly efficient low temperature CO oxidation under ambient conditions
A meso-structured Pd/NiO catalyst, fabricated through a controlled pyrolysis and in situ reduction protocol, showed much higher catalytic activity and stability for CO oxidation under ambient conditions.
Iron-dependent turnover of IRP-1/c-aconitase in kidney cells
The kidney plays an important role in iron homeostasis and actively reabsorbs citrate. The bifunctional iron-regulatory protein IRP-1 potentially regulates iron trafficking and participates in citrate metabolism as a cytosolic (c-) aconitase. We investigated the role of cellular iron status in determining the expressi…
Improved oral bioavailability of novel antithrombotic S002-333 via chitosan coated liposomes: a pharmacokinetic assessment
S002-333, a novel anti-thrombotic agent, exhibits excellent platelet mediated antithrombotic action and subsequently has no effect on the coagulation cascade.
A computational study of tri-s-triazine-based molecules as ambipolar host materials for phosphorescent blue emitters: effective geometric and electronic tuning
The design of tri- s -triazine derivatives as host materials.
Tetracoordinate silicon complexes of 1,2-bis(indol-2-yl)benzene as blue-emitting dyes in the solid state
1,2-Bis(indol-2-yl)benzene was prepared and found to serve as an effective bidentate ligand to form stable silicon complexes bearing two N-Si bonds. These complexes take boat-shaped 2,7-diaza-1-silepin structures, which undergo a butterfly-like conformational motion whose activation barriers were determined by shape a…
Crystal structure and physical properties of Cr and Mn oxides with 3d 3 electronic configuration and a K 2 NiF 4 -type structure
YSrCrO 4 is first synthesized. The magnetic and dielectric properties of YCaCrO 4 , LaSrCrO 4 and A 2 MnO 4 (A = Sr and Ca) are investigated together with YSrCrO 4 .
Rheological behavior of hydrophobically modified polysulfobetaine methacrylate aqueous solution
Polysulfobetaine methacrylate (PSBMA) that was hydrophobically modified with methacrylic acid 2,3-epoxypropyl ester (GMA) was synthesized via micellar copolymerization method. Viscosity of the hydrophobically modified PSBMA solution was sensitive to added salt concentration.
Facile electrochemical synthesis of titanium dioxide dendrites and their electrochemical properties
Titanium dioxide (TiO2) dendrites were successfully prepared by a simple electrochemical deposition technique in acidic solution. The TiO2 dendrites showed outstanding electrochemical properties.
Structural changes of block copolymers with bi-modal orientation under fast cyclical stretching as observed by synchrotron SAXS
Load-bearing tissues are composite materials that depend strongly on anisotropic fibre arrangement to maximise performance. One such tissue is the heart valve, with orthogonally arranged fibrosa and ventricularis layers. Their function is to maintain mechanical stress while being resilient. It is postulated that while…
Effect of the liquid crystal solute on the rotator phase transitions of n-alkanes
Recent experimental studies have shown that the liquid crystal substance plays an important role in determining the structures and the phase transitions of the different rotator phases in binary mixtures of n -alkane and liquid crystals.
MODELING THE HYGRO-THERMO-MECHANICAL AGGLOMERATION RELATIONS OF CARBON-EPOXY HYBRID NANOCOMPOSITES
In the present work, the hygro-thermo-mechanical properties of hybrid nanocomposites are presented under the agglomeration effects of carbon nanotubes in the polymer matrix. In order to study the composite behaviors, the Voigt and Reuss homogenization method is adopted to present new relations for a hybrid nanocomposi…
Hierarchical manipulation of uniform multi-nanoparticles by electrochemical coupling assembly
Multiple uniform nanoparticles are electrochemically integrated into thin bulk-hybrid gradient or periodic tandem multilayer films for their use in photovoltaic devices.
Synthesis of palladium nanoparticles on TiO 2 (110) using a beta-diketonate precursor
The adsorption of palladium hexafluoracetylacetone (Pd(hfac)2) and nucleation of Pd nanoparticles on TiO2(110) surface were observed using scanning tunneling microscopy (STM). Surface species of Pd(hfac)* and Ti(hfac)* uniformly adsorbed on TiO2(110) upon exposure of Pd(hfac)2. No preferential nucleation was observed…
Supercapacitors: An Interface‐Induced Co‐Assembly Approach Towards Ordered Mesoporous Carbon/Graphene Aerogel for High‐Performance Supercapacitors (Adv. Funct. Mater. 4/2015)
On page 526, R. L. Liu, D. Q. Wu, and co-workers develop an interface-induced co-assembly approach to fabricate hierarchically porous composites with ordered mesoporous carbon wrapping around macroporous graphene aerogels. The orientation of the mesopores in the resulting composites can be tuned by the adding amount o…
Rapid Breakdown Anodization for the Preparation of Titania Nanotubes in Halogen-Free Acids
TiO 2 nanotubes were successfully prepared based on rapid breakdown anodization (RBA) without halogen ions. Typically, ethylene glycol (EG) containing hydrated oxalic acid, high temperature (>50°C), and high potential (>80 V) are required to produce RBA nanotubes without halogen ions. However, the restricted electroch…
Unusual magnetic damping effect in a silver–cobalt ferrite hetero nano-system
The analysis of static and dynamic magnetic response of CoFe 2 O 4 –Ag hetero nano-system revealed, with the aid of micromagnetic simulations, a severe alteration of the magnetic relaxation behaviour of CoFe 2 O 4 upon interaction with non-magnetic Ag.
Atomistic modeling of a KRT35/KRT85 keratin dimer: folding in aqueous solution and unfolding under tensile load
We present an atomistic model of a full KRT35/KRT85 dimer, a fundamental building block of human hair. For both monomers initial structures were generated using empirical tools based on homology considerations, followed by the formulation of a naiïve dimer model from docking the monomers in vacuum. Relaxation in aqueo…
