Abstract The synthesis and the structural and magnetic characterization of two new cobalt(II) compounds [Co 4 (TTA) 4 (OMe) 4 (EtOH) 4 ] ( 1 ) and [Co 4 (TTA) 4 (OMe) 4 (MeOH) 4 ] ( 2 ) (TTA = 4,4,4‐trifluoro‐1‐thienoyl‐2,4‐butanedione) are reported. The structures consist of a tetranuclear Co 4 O 4 core in a cubane f…
Abstract The aim of this study is to investigate the corrosion behaviour of three ZrTi alloys (denoted with Zr5Ti, Zr25Ti, and Zr45Ti) in 0.9% NaCl solution. For comparison, cp‐Ti was also investigated. In order to study the localized corrosion resistance and corrosion behavior at open circuit potential versus time, t…
Recent developments in nanotechnology have provided new tools for both cancer imaging and treatment. The functionalization of the nanocarrier based drugs using biological ligands allows increasing specificity of drug targeting enhancing efficacy and reducing side effects. In this paper some current nanocarrier based d…
Abstract Pitting corrosion is one of the most common mechanisms of surface damage on stainless steels. Electrochemical methods have been preferentially applied for the evaluation of the pitting corrosion resistance of stainless steels in the laboratory. Nevertheless, some of them are not reliable enough and in general…
We successfully controlled the crystallographic surface of ZnSn(OH)(6) crystals and systematically obtained ZnSn(OH)(6) crystals in different shapes including cubes, truncated cubes, cuboctahedrons, truncated octahedrons, and octahedrons using a simple solvothermal method in a methylcellulose (MC) ethanol/water soluti…
The facile axial ligand exchange properties of gallium(III) protoporphyrin IX in methanol solution were utilized to explore self-association interactions by NMR techniques. Structural changes were observed, as well as competitive behavior with the ligands acetate and fluoride, which differed from that seen with the sy…

In this study, we report a novel and facile single-phase synthesis of stable AuNP-CTAB(NA) conjugates with good dispersibility, bearing a bilayer of cationic surfactant, cetyltrimethylammonium bromide (CTAB) supported by N-nonylamine (NA) as a cosurfactant. We investigated AuNP-CTAB(NA) conjugates by (1)H NMR spectros…
Friedrich Wöhler and Justus von Liebig discovered the first case of molecular polymorphism when crystallizing benzamide in 1832. (1) Thus far only microcrystalline mixtures of metastable phases with the thermodynamically stable form I were available. Optimizing the conditions for crystal growth now gave access to sing…
In and out of tube: Robust poly-3,4-ethylene-dioxythiophene nanostructures in the form of nanopore arrays and inverse nanotube arrays are obtained by site-selective deposition into TiO(2) nanotubes. The deposition process critically depends on the applied potential and is in line with three-dimensional (3D) progressiv…
Polymer brushes (PBs) have been used as supports for the immobilization of palladium complexes on silicon surfaces. The polymers were grown by surface-initiated atom-transfer radical polymerization (SI-ATRP) and postdecorated with dipyridylamine (dpa) ligands. The pendant dpa units were in turn complexed with [Pd(OAc)…
The paper proposes the study of the kinetostatic behavior of a flexible universal joint for minirobotic applications. A closed-form formulation of joint’s compliance is obtained for linear elastic material and small displacements. It is also presented a numerical study that considers the joint realized with a superela…
Cross sections for $K$-shell ionization by electron impact were determined from films of Al, Si, and Ti and their oxides deposited on carbon substrates, for incident energies between 2.5 and 25 keV. The spectral processing of the x-ray emission spectra took into account corrections due to the presence of a spontaneous…
UC CEIN was established with funding from the US National Science Foundation and the US Environmental Protection Agency in 2008 with the mission to study the impact of nanotechnology on the environment, including the identification of hazard and exposure scenarios that take into consideration the unique physicochemica…
The dimerization of anthracene by a [4π + 4π] cycloaddition is one of the oldest and best known reactions in photochemistry. In the series of tethered bichromophoric arenes, this reaction type could be extended to anthracene-naphthalene, naphthalene-naphthalene and recently even to anthracene-benzene and naphthalene-b…
The cyclic deformation behavior of [001] oriented Fe-28Ni-17Co-11.5Al-2.5Ta (at.%) shape memory single crystals was investigated under tension. Dog-bone shaped specimens were tested up to 100 cycles after different aging heat treatments in order to characterize the cyclic stress–strain response and functional degradat…
We show that the amorphization process in phase-change In 2 Se 3 nanowires grown by chemical vapor deposition can be driven by electronic effects and does not require the conventional thermal melt-quench process. In particular, using transmission electron microscopy, in situ single-nanowire Raman spectroscopy, scannin…
The Ba 2 Bi x Sc 0.2 Co 1.8– x O 6−δ ( x = 0.1 or 0.2) cubic perovskites are confirmed to be mixed-valent Co 3+ /Co 2+ oxides that, as mixed oxide-ion and electronic conductors, are superior cathode materials for an intermediate-temperature solid oxide fuel cell catalyzing the oxygen-reduction reaction. Neutron powder…
Aqueous acetone mixtures represent a good example of perfectly miscible liquids in reality, and that hard to mix in silico. This is related to a key problem in molecular simulations, which is to distinguish between strongly micro-segregated mixtures from phase-separated ones. The Kirkwood-Buff integrals of in silico a…
This work describes a new one-step method for the preparation of AuNP/LDH nanocomposites via the polyol route. The novelty of this facile, simple synthesis is the absence of additional reactants such as reductive agents or stabilizer, which gives the possibility to obtain phase-pure systems free of undesiderable effec…
