1 H- 1 H distance restraints, derived from nuclear Overhauser effects (NOEs) in macromolecules, are generally restricted to protons close in space and characterized by large inaccuracies due to spin diffusion. Perdeuteration of molecules with selective incorporation of protons into few specific methyl sites greatly re…
Collagen is the most abundant protein in animals. Every third residue in a collagen strand is a glycine with phi, psi = -70 degrees, 175 degrees. A recent computational study suggested that replacing these glycine residues with D-alanine or D-serine would stabilize the collagen triple helix. This hypothesis is of subs…
The objective of this study was to determine the effect of rolling pass on AZ31 magnesium alloy sheets, which were produced by a new concept process, so-called equal-channel angular rolling process. Processing that causes continuous shearing deformation leads to a shifting of the crystal orientation from basal plane t…
Time-sequenced contact-force micrographs show that the (104) calcite cleavage surface reconstructs in humid air through pit formation and film growth. After 8 h at 80% relative humidity (RH), 50% to 80% of the surface is covered by islands that are flat-topped and 1-nm high. The lateral growth rates of individual isla…
A newly designed Gemini-shaped hexabenzocoronene amphiphile (1), carrying an isothiouronium ion-appended side chain, self-assembles in CH2Cl2 to form a nanotubular object, whose graphitic wall is densely covered by a positively charged molecular layer of isothiouronium ion pendants. The graphitic nanotube can be dispe…
We report a detailed investigation of the processes of the surface segregation in correlation with the wetting properties of perfluoroalkyl end-functionalized linear aromatic oligoesters. We have compared properties of films containing different fluorine concentration prepared by the spin-coating technique and by melt…
In the last years, several investigations were performed in the ternary system Sn−B−O as a simplified variant of the tin-based amorphous composite oxide (TCO), a material in use as negative electrode of lithium-ion rechargeable batteries. All compounds in this system are glasses, so the synthesis of crystalline approx…
We describe a new approach for optical imaging that combines the advantages of molecularly targeted plasmonic nanoparticles and magnetic actuation. This combination is achieved through hybrid nanoparticles with an iron oxide core surrounded by a gold layer. The nanoparticles are targeted in-vitro to epidermal growth f…
In this paper, highly ordered, extremely hydrothermal stable SBA-15/Al-SBA-15 has been synthesized using mixed surfactants (triblock copolymer, P123, and semifluorinated surfactant, FSO-100) as a template at a high aging temperature (140−180 °C) with the assistance of NaCl. Thus - synthesized SBA-15 maintained the wel…
Synchrotron X-Ray Microtomography Study of the Role of Y in Corrosion of Magnesium Alloy WE43, Davenport, Alison J., Padovani, Cristiano, Connolly, Brian J., Stevens, Nicholas P. C., Beale, Thomas A. W., Groso, Amela, Stampanoni, Marco
5,20-Diethynyl substituted [26]hexaphyrins(1.1.1.1.1.1) undergo a thermal or spontaneous cross-bridging reaction to provide trans -vinylene-bridged [26]hexaphyrins, probably through strongly folded conformations. Facile aromatic−antiaromatic switching of vinylene-bridged hexaphyrins has been demonstrated upon two-elec…
Mesoporous silica materials with a variety of morphologies, such as monodisperse microspheres, gigantic hollow structures comprising a thin shell with a hole, and gigantic hollow structures consisting of an outer thin shell and an inner layer composed of many small spheres, have been readily synthesized in mixed water…
A rational approach to the formation of pure heteropolymetallic lanthanide complexes that uses a two-step assembly strategy and exploits the different size requirements of the two metals included in the final structure is described. The investigation of the assembly of [LnL2](Otf) (L = 2,2':6',2' '-terpyridine-6-carbo…
We present dynamic light scattering (DLS) measurements of soft poly(methyl-methacrylate) (PMMA) and polyacrylamide (PA) polymer gels prepared with trapped bodies (latex spheres or magnetic nanoparticles). We show that the anomalous diffusivity of the trapped particles can be analyzed in terms of a fractal Gaussian net…
We describe a simple and versatile protocol to prepare water-soluble multifunctional nanostructures by encapsulation of different nanoparticles in shell cross-linked, block copolymer micelles. This method permits simultaneous incorporation of different nanoparticle properties within a nanoscale micellar container. We…
A new and efficient procedure for ligand exchange on core−shell fluorescent nanocrystals is reported. The process involves the reaction of carbon disulfide with a ligand containing an amino group. The resulting dithiocarbamate is strongly bound to the surface of the quantum dots leading to a secure coating of the nano…
The electrochemical performance of negative electrodes based on commercially available crystalline Si powder and sodium carboxymethyl cellulose (CMC) binder was investigated. Compared to the conventional binder, polyvinylidene fluoride, Si electrodes using CMC binder show vastly improved cycling performance. A high sp…
Abstract A software package was developed for the simulation and optimization of a multi‐bed adiabatic reactor for the catalytic oxidation of SO 2 , using a heterogeneous plug flow model. The orthogonal collocation (OC) technique with up to eight collocation points was used for the solution of a nonlinear, two‐point b…
Abstract A new second order nonlinear optical coordination complex crystal tris allylthiourea zinc bromide was synthesized and grown from ethanol for the first time. Elemental analyses, X‐ray powder diffraction and infrared spectroscopy confirmed the formation of the new material. The thermal characterization was dete…
The mechanism of field emission from a highly P-doped diamond (111) surface has been studied by field/photo emission electron micro-spectroscopy. It was found that field emission peaks were located at -3 to -6 eV with respect to the substrate Fermi level ( E F ) and that photoemission peaks were located at -1 to +2 eV…
