The water-exchange reaction in two diastereoisomers of the clinical magnetic resonance imaging contrast agent [Gd(HP-DO3A)(H(2)O)] (also known as ProHance) has been studied using ab initio simulations. On the basis of the molecular-level details of the mechanism derived from these simulations in aqueous solution, we u…
Eight novel compounds were prepared by reaction of 5-(bromo- propoxyphenyl)-10,15,20-triphenylporphyrin with oxazole thiols, 1,3,4-oxadiazole thiols and 1,3,4-thiadiazole thiols, and their structures confirmed by UV-vis, IR, 1H-NMR, MS and elemental analysis. The assessment of indirectly measured 1O(2) production rate…
An analytic theory describing soft x-ray diffraction by Lamellar Multilayer Gratings (LMG) has been developed. The theory is derived from a coupled waves approach for LMGs operating in the single-order regime, where an incident plane wave can only excite a single diffraction order. The results from calculations based…
Abstract The new thioantimonate [Ni(tren) 2 ] 2 [Ni(tren)(en)] 2 (Sb 4 S 8 ) 2 ·0.25H 2 O (tren = tris(2‐aminoethyl)amine; en = ethylenediamine) was obtained under solvothermal conditions. The compound crystallizes in the non‐centrosymmetric space group P 1 with a = 9.424(2), b = 13.010(3), c = 18.883(4) Å, α = 102.46…
The structural and electrical properties of some CdI 2 doped silver borophosphate glasses and glass nanocomposites of compositions 0.2CdI 2 – 0.8(0.50Ag 2 O – 0.50( x B 2 O 3 – (1 – x )P 2 O 5 )), prepared by the melt quenching method, are reported in this paper. The X-ray diffraction study reveals the amorphous natur…
Scanning tunneling microscopy and scanning tunneling spectroscopy (STS) at low temperatures were applied to prove lateral inhomogeneities in the electronic properties of a single layer of graphene on the Ru(0001) surface. We found two different types of STS curves depending on the location within the moir\'e pattern o…
BACKGROUND: Magnesium alloys as biodegradable implant materials received much interest in recent years. It is known that products of implant degradation can induce several types of immune response. Hence, the aim of this study was to examine the morphological changes of efferent lymph nodes after implantation of diffe…
Intrinsically self-stabilized nanofibril bundles of poly(1-aminoanthraquinone) (PAQ) were facilely synthesized by the chemical oxidative polymerization of 1-aminoanthraquinone. Critical polymerization parameters such as the monomer concentration, medium, oxidant species, temperature, and time were studied to significa…
A deep analysis of bi- and plano-concave lens made of stacked subwavelength hole arrays in terms of focus and angular power distribution is presented. The key difference between these left-handed extraordinary transmission lenses (LHET-lenses) and the classical metallic lenses is based on the fact that contrary to the…
The magnetocaloric properties of the as-consolidated nanocrystalline and coarse-grained gadolinium metals were studied in the present work. With the decrease of Gd grains from micrometer to nanometer range, magnetic entropy change drops surprising from 10.07 to 4.47 J kg −1 K −1 at a magnetic-field change of 5 T, and…
The design of electromagnetic devices submitted to high mechanical stress is a growing issue and requires consequently appropriate modeling tools. We propose in this paper to implement a multiscale model for magneto-elastic behavior into a finite-element code. The 2-D magneto-elastic constitutive law is derived from a…
The effect of the variation of B-H properties obtained by different means and data access modes on iron loss and flux in grain oriented (GO) silicon steel laminations is investigated under different exciting frequencies in order to determine an efficient numerical approach to model the lamination configurations. The c…
Colloidal semiconductor nanocrystals typically have ligands attached to their surfaces that afford solubility in common solvents but hinder charge transport in nanocrystal films. Here, an alternative route is explored in which bare germanium nanocrystals are solubilized by select solvents to form stable colloids witho…
We report a one-step, mild method to modify antifouling oligo(ethylene glycol)-terminated self-assembled monolayers. We demonstrate for the first time that self-polymerized dopamine, previously reported as an underwater adhesive, can be patterned on typical antifouling surfaces by microfluidic patterning or microconta…
Poly(ω-pentadecalactone) (PPDL), a model polymer in the poly(ω-hydroxyl fatty acids) family, is a new biopolymer with monomer synthesized by yeast-catalyzed ω-hydroxylation of fatty acids. In this study, deformation-induced structural changes in two PPDL samples with different molecular weights were studied by in situ…
Here we report the synthesis of monodispersed indium nanoparticles by evaporation/condensation of indium shot using the solvated metal atom dispersion (SMAD) technique, followed by digestive ripening in low boiling point (BP 38 °C) methylene chloride and in a high boiling point (BP 110 °C) toluene solvent. The as-prep…
In this paper, a general equation of state (EOS) valid for fluids in the vicinity of the glass transition is derived on the basis of its isothermal precursor. This EOS is able to predict the density scaling of both isobaric and isothermal PVT data and it explicitly involves the scaling exponent γ(EOS), which is most l…
A platform for fabrication of conductive copolymer based resistive biosensor on nonconductive substrate is demonstrated. The −COOH functional groups in the copolymer of thiophene-3-acetic acid (TAA) and 3,4-ethylenedioxythiophene (EDOT) was employed for immobilization of a biomolecule. The sheet resistance of the cond…
Abstract Fluorescent silica nanoparticles (FSNPs) with efficient light emission, colloidal stability, and size tunability are fabricated by one‐pot, two‐step Stöber and reverse microemulsion techniques. Tetraphenylethene (TPE)‐ and silole‐functionalized siloxanes are facilely synthesized by click reactions and their s…
The one-pot synthesis of patchy particles with morphologically tunable optical properties by the heterogeneous nucleation and growth of silver onto colloidal silica particles is described. Heat treatment of the silica and coating reaction conditions can be optimized in order to produce full yields of patchy particles.…
