UNLABELLED: Many advanced molecular imaging agents are currently being investigated preclinically. Especially, liposomes, have proven to be very promising carrier systems for diagnostic agents for use in single-photon emission computed tomography (SPECT) or magnetic resonance imaging (MRI), as well as for therapeutic…
A coarse-grained lattice-gas model in three dimensions is developed to study the self-assembly of nanoparticles into micrometer-sized rings from a thin liquid film containing the nanoparticles. The model describes the nanoparticles as well as the solvent on length scales that are typical of the solvent bulk correlatio…
Recently, some accidents in spacecraft due to charging up by irradiation of charged particles have been reported. Some of them are caused by a surface discharge, which normally takes place in a plasma environment in space. Some others seem to be caused by a discharge due to an accumulation of charge in the bulk of mat…
Brush macromolecules having poly( l -lactide) (PLLA) and poly(styrene) (PS) side chains were prepared on the backbone of partially esterified poly(2-hydroxyethyl methacrylate) (PHEMA) by using a combination of atom transfer radical polymerization (ATRP) and ring-opening polymerization. The number-average degrees of po…
In this paper, we report a highly efficient organic-inorganic nanocomposite electrode with enhanced double layer capacitance, which has been synthesized using 3,4-ethylenedioxythiophene and crystalline molybdenum trioxide (MoO3) in the presence of an external oxidizing agent. The interlayer spacing of MoO3 upon interc…
Studies on (i) microwave magnetoelectric (ME) interactions in ferrite-piezoelectric bilayers and (ii) electric field tunable ME signal processing devices are discussed. An electric field E applied to the bilayer produces a mechanical deformation in the piezoelectric, resulting in a frequency (δ f) or magnetic field sh…
Abstract n‐Type diamond formation is one of the most important issues for the electronic application of diamond. Phosphorus is the best n‐type dopant candidate at the moment. We have succeeded in growing high‐quality phosphorus‐doped diamond thin films on {111} diamond substrates. Although the ionization energy of the…
Brain tumors remain a significant health problem. Advances in the biology of the blood-brain barrier are improving the ability of researchers to target therapeutic peptides, small molecules and other drugs to brain tumors. Simple methods to improve blood-brain barrier penetration include chemical modification, glycosy…
We have experimentally demonstrated for the first time, shear‐induced development of bubble size and shape in a rhyolitic melt. The deformation experiments have been performed by using an externally heated, piston‐cylinder type apparatus with a rotational piston. At 975°C, the vesiculated rhyolitic melts having cylind…
ZnO thin films with various thicknesses were prepared onto glass substrates by pulsed laser deposition. The crystallinity, microstructure and surface morphology of ZnO thin films were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and scanning probe microscopy (SPM). As the thickness of th…
We report the development of a measurement system capable of monitoring and characterizing the main features of the leakage current flowing on a polluted insulator string of a high-voltage transmission line. The system comprises a fiber-optic sensor, directly connected to one insulator of the string, that emits a samp…
Abstract Bisphenol A based low‐molecular‐weight epoxy resin was modified with epoxidized soybean oil, which exhibit viscosity reducing ability comparable to commercial grade active diluents. The studied compositions showed a non‐Newtonian rheological behavior, typical for Bingham liquids. The values of the flow index…
Analytical solutions for the deformation, penetration, and perforation of composite plates and sandwich panels subjected to quasi-static punch indentation and projectile impact are derived. Discrete spring-mass models are used to calculate the impact response of the composite plates and sandwich panels. Equivalent loa…
The authors measure and compare the electronic transport properties of individual single-wall carbon nanotubes (SWNTs) and SWNT networks of varying thickness (Skakalova, 2006). Study of electronic transport through an individual metallic SWNT suggests Luttinger liquid mechanism. Arrhenius plot shows that there is no s…
ABSTRACT: Gelatins can be obtained from different sources and prepared using different processes, and the end product gelatin may vary in amino acid composition and molecular weight distribution. In the present study, the variation in “protein color” development among gelatins in colorimetric total protein content mea…
A series of near-infrared (NIR) electrochromic and electroluminescent polymers containing the pendant dinuclear ruthenium complexes were synthesized and characterized. All the polymers are near-infrared (NIR) electrochromic, displaying an intense absorption centered at 1600 nm upon oxidation to the mixed-valence state…
This review discusses some of the most common polymer scaffold fabrication techniques used for tissue engineering applications. Although the field of scaffold fabrication is now well established and advancing at a fast rate, more progress remains to be made, especially in engineering small diameter blood vessels and p…
A simple method for synthesizing Cu2S nanocrystals with different sizes and shapes via solution-phase thermolysis of a copper alkyldithiolate polymer precursor was developed. Monodisperse Cu2S nanodisks can self-assemble into novel corncoblike structure of stacked disks. This solution-phase thermolysis approach provid…
Mesenchymal stem cells (MSCs) are a promising candidate cell for tissue engineering. Magnetic resonance imaging (MRI) has been proven effective in visualizing iron-labeled stem cells; however, the efficiency of this approach for visualization of cells seeded on scaffolds intended for use as tissue-engineered heart val…
