We have investigated the magnetic properties of a piezoelectric actuator/ferromagnetic semiconductor hybrid structure. Using a GaMnAs epilayer as the ferromagnetic semiconductor and applying the piezo stress along its [110] direction, we quantify the magnetic anisotropy as a function of the voltage ${V}_{p}$ applied t…
In this work we present the result of the first experimental investigation of the role of oxygen content on the properties of the HoBaCo2O5+delta layered cobaltite. We have measured the variation of oxygen content as a function of temperature and oxygen partial pressure by means of thermogravimetry coupled to chemical…
Microwave treated water soluble and amide functionalized single walled carbon nanotubes have been investigated using femtosecond degenerate pump-probe and nonlinear transmission experiments. The time resolved differential transmission using 75 femtosecond pulse with the central wavelength of 790 nm shows a bi-exponent…
We investigate the surface roughness influence on the gain from parametric amplification in nanoresonators in presence of thermomechanical and momentum exchange noise. The roughness is characterized by the rms amplitude w, the correlation length X, and the roughness exponent 0>Qgas, the influence of surface roughness…
Abstract With the program HistCite™ it is possible to generate and visualize the most relevant papers in a set of documents retrieved from the Science Citation Index . Historical reconstructions of scientific developments can be represented chronologically as developments in networks of citation relations extracted fr…
Magnetic cobalt spinel ferrite nanoparticles coated with biocompatible polygalacturonic acid were functionalized with ligands specific for targeting expressed EphA2 receptors on ovarian cancer cells. By using such magnetic nanoparticle-peptide conjugates, targeting and extraction of malignant cells were achieved with…
Abstract Water‐soluble conjugated polymers have attracted much attention in the biosensor community because of recent exciting experimental results. The transfer of excitation energy along the whole backbone of the conjugated polymer to the reporter results in an amplified fluorescence signal, which makes them useful…
We report and explain circular dichroism in semiconductor quantum dots. CdS nanocrystals capped with penicillamine enantiomers were prepared and found to be both highly luminescent and optically active. No new features in circular dichroism were observed as the nanocrystal grew larger. Density functional calculations…
BACKGROUND: The development of nanoparticles for the delivery of therapeutic agents has introduced new opportunities for the improvement of medical treatment. Recent efforts have focused on developing targeted nanoparticles, which are formulated by (for therapeutic delivery) functionalizing nanoparticle surfaces with…
The B all and N all: Soluble, linear, high molecular weight polyaminoborane homopolymers and copolymers have been synthesized by iridium-catalyzed dehydrocoupling of readily available amine–borane adducts RNH2⋅BH3 (R=H, Me, nBu).
A new type of fluorescence sensory material with high sensitivity, selectivity, and photostability has been developed for vapor probing of organic amines. The sensory material is primarily based on well-defined nanofibers fabricated from an n-type organic semiconductor molecule, N-(1-hexylheptyl)perylene-3,4,9,10-tetr…
Liquid crystals shining bright. A highly efficient platinum(II) luminophore is rendered liquid crystalline using a simple and flexible synthetic approach. Ordering in the liquid-crystalline state allows monomer emission when the characteristic for the material is exciplex-like emission. More than that, emission charac…
Abstract Conducting polymer nanostructures have recently received special attention in nanoscience and nanotechnology because of their highly π ‐conjugated polymeric chains and metal‐like conductivity, such that they can be regarded not only as excellent molecular wires, but also as basic units for the formation of na…
Abstract A rapid and readily reproducible seed‐based method for the production of high quality silver nanoprisms in high yield is presented. The edge‐length and the position of the main plasmon resonance of the nanoprisms can be readily controlled through adjustment of reaction conditions. From UV‐vis spectra of solut…
Nanoparticles show their promise for improving the efficacy of drugs with a narrow therapeutic window or low bioavailability, such as anticancer drugs and nucleic acid-based drugs. The pharmacokinetics (PK) and tissue distribution of the nanoparticles largely define their therapeutic effect and toxicity. Chemical and…
The performance of a combinatorial simultaneous optimization (SO) algorithm is tested using experimental LEED I ( E ) data from Cu(100) and Fe 0.57 Al 0.47 (100) surfaces. SO optimizes structures taking advantage of the experimental database at two levels: (i) commensurate subsets of the database with the number of un…
We introduce a new implementation of the finite-difference time-domain (FDTD) algorithm with recursive convolution (RC) for first-order Drude metals. We implemented RC for both Maxwell's equations for light polarized in the plane of incidence (TM mode) and the wave equation for light polarized normal to the plane of i…
Superlenses based on metamaterials are promising candidates for achieving subwavelength resolution. We report here our experimental studies on super-resolution imaging from one-dimensional (1D) negative index metamaterial superlenses at microwave frequencies. The metamaterial structure under investigation is shown to…
We have observed homogeneous crystal nucleation in Lennard-Jones liquid by molecular dynamics simulations. A clear nucleation time delay has been observed at $T=0.677{T}_{m}$ and $T=0.629{T}_{m}$ indicating the presence of a barrier, in contrast to recent reports [Trudu et al., Phys. Rev. Lett. 97, 105701 (2006)]. The…
In several archaea of the Euryarchaeota, the glycolytic flux proceeds through a modified version of the Embden-Meyerhof pathway, where the phosphofructokinase and glucokinase enzymes use ADP as the phosphoryl donor. These enzymes are homologous to each other. In the hyperthermophilic methanogenic archaeon Methanocaldo…
