It has recently been shown that Severe Plastic Deformation (SPD) techniques could be used to obtain nanostructured metal hydrides with enhanced hydrogen sorption properties. In this paper we review the different SPD techniques used on metal hydrides and present some specific cases of the effect of cold rolling on the…
Two new polyoxovanadates (Co(N(3)C(5)H(15))(2))(2)[{Co(N(3)C(5)H(15))(2)}V(15)Sb(6)O(42)(H(2)O)]·5H(2)O (1) and (Ni(N(3)C(5)H(15))(2))(2)[{Ni(N(3)C(5)H(15))(2)}V(15)Sb(6)O(42)(H(2)O)]·8H(2)O (2) (N(3)C(5)H(15) = N-(2-aminoethyl)-1,3-propanediamine) were synthesized under solvothermal conditions and structurally charac…
Whereas, commonly, Langmuir monolayers are structurally dominated by the aliphatic chains, we present here the first case of monolayers where the chains merely serve anchoring at the air/water interface and the organization is dictated by the hydrophilic head group self-assembling in a hexagonal lattice. These head gr…
Graphene prepared on Cu foil by chemical vapor deposition was studied as a function of post growth cooling conditions. CuO islands embedded in the graphene film were discovered and studied by scanning electron microscopy, atomic force microscopy, and X-ray photoemission spectroscopy. It is shown that nanostructured ho…
Novel protein chimeras constituted of "silk" and a silica-binding peptide (KSLSRHDHIHHH) were synthesized by genetic or chemical approaches and their influence on silica-silk based chimera composite formation evaluated. Genetic chimeras were constructed from 6 or 15 repeats of the 32 amino acid consensus sequence of N…
Compromise between the electrical conductivity and Seebeck coefficient limits the efficiency of chemical doping in the thermoelectric research. An alternative strategy, involving the control of a local crystal structure, is demonstrated to improve the thermoelectric performance in the RE(2)SbO(2) system. The RE(2)SbO(…
We have experimentally and numerically investigated photo-induced voltage (PIV) effect across a Au film with a dielectric grating. We observed strongly enhanced voltage when surface plasmon polariton (SPP) is excited. It was found that electrons in the Au film are driven to the propagation direction of SPP. We have nu…
The adsorption of gold clusters (Au n, n = 1–10) on the minority surface, (001), of anatase titanium dioxide (TiO 2 ) has been studied in the framework of density functional theory. Various adsorption geometries of gold (Au) clusters on clean, unreconstructed TiO 2 (001) have been investigated. It is found the adsorpt…
A simple composite analytic expression has been developed to approximate the electron range in materials. The expression is applicable over more than six orders of magnitude in energy (; MeV) and range ( 10-9-10-2m), with an uncertainty of ≤ 20% for most conducting, semiconducting, and insulating materials. This is ac…
In the objective of developing ligands that simultaneously satisfy the requirements for MRI contrast agents and near-infrared emitting optical probes that are suitable for imaging, three isoquinoline-based polyaminocarboxylate ligands, L1, L2 and L3, have been synthesized and the corresponding Gd(3+), Nd(3+) and Yb(3+…
A void in the issue: A one-step self-assembly of γ-Keggin sandwich-type silicotungstates with M2Zn2 (M=Co, Ni, Zn) tetranuclear cores and tetrabutylammonium cations gave porous ionic crystals. These porous crystals are hollow frameworks containing large voids (ca. 38×38×38 Å3, see picture, voids yellow), between which…
Now we are six: Planar B6 rings embedded in one-dimensional Ti7 wheels have been found in the crystal structure of a solid-state phase (Ti7Rh4Ir2B8) for the first time. First-principles calculations indicated strong BB bonding but also significant interactions with the surrounding titanium atoms (see picture).
Crystal growth of cubic BaTiO 3 in the presence of polyethylene glycol-200 (PEG-200) is investigated step by step using powder X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. Titanium precursor Ti(OC 4 H 9 ) 4 aggregates with PEG to form spherical colloidal particles at the very…
Dispersion plays an important role in aqueous chemical coating process for the preparation of BaTiO 3 ‐based powder for base‐metal‐electrode multilayer ceramic capacitors ( BME ‐ MLCC s) in our previous research. In this article, a powerful sand mill ( SC ‐milling) machine is utilized instead of traditional ball milli…
Spherical nickel cobalt aluminum hydroxide (Ni(0.80)Co(0.15)Al(0.05)-hydroxide, NCA) was prepared by a continuous coprecipitation method. A new design of the Al solution and the feeding method was applied, which enabled to prevent rapid precipitation of Al(OH)(3) and to obtain spherical NCA with large enough particle…
Multiferroics have received a great deal of attention because of their fascinating physics of order-parameter cross-couplings and their potential for enabling new device paradigms. Considering the rareness of multiferroic materials, we have been exploring the possibility of artificially imposing ferroelectricity by st…
PEGylated polylysine dendrimers show promise as novel drug delivery systems with the potential to direct site specific deposition patterns and to reduce toxicity at nontarget sites. Here the activity and toxicity profiles of a generation 5 polylysine dendrimer with 50% surface conjugation of PEG1100 and 50% surface co…
Abstract BACKGROUND: Owing to the rapid depletion of petroleum fuel, the production of bio‐butanol has attracted much attention. However, low butanol productivity severely limits its potential industrial application. It is important to establish an approach for recovering low‐concentration butanol from fermentation br…
Lipid bilayers are biomembranes common to cellular life and constitute a continuous barrier between cells and their environment. Understanding the interaction of nanoparticles with lipid bilayers is an important step toward predicting subsequent biological effects. In this study, we assessed the affinity of functional…
Aiming to explore cooperative interactions between plasmonic metal and semiconductor nanostructures as well as their special plasmon resonant properties, we synthesized Au@Cu 2 O core–shell nanoparticles to demonstrate the dramatic influence of dielectric shell both experimentally and theoretically. The extinction spe…
