The authors of this Communication recently noted that a key word in a sentence in their publication appeared incorrectly. Thus, the penultimate sentence in the penultimate paragraph on page 2369 should read: Hence, it is safe to conclude that the number of nanocrystals (nuclei) formed in the initial nucleation stage i…
Die Autoren bemerkten kürzlich einen sinnverändernden Fehler in dieser Zuschrift. Der vorletzte Satz des vorletzten Abschnitts auf S. 2475 muss lauten: “Hence, it is safe to conclude that the number of nanocrystals (nuclei) formed in the initial nucleation stage increased significantly with decreasing initial oleic ac…
The authors have measured the contribution of CO adsorbed on different bonding sites to the resistivity of epitaxial Cu(100) films. Through an analysis of the correlation between surface resistivity and temperature-programed desorption measurements, CO on terraces is found to affect the resistance much more strongly t…
The cluster {(Mo)Mo5}12Fe(III)30 1 a present in compound 1 (cluster diameter approximately 2.3 nm), which belongs to the family of nanoscale spherical porous {(Mo)Mo5}12{Linker}30 capsules that allow a new type of nanochemistry inside their cavities as well as unprecedented aggregation processes under gaseous, solutio…
Five local clays were characterised by several physicochemical methods to predict their pozzolanic reactivity. The studied samples were treated thermally at 600, 700 and 800°C. The heat-treated samples were characterised by X-ray diffraction. The pozzolanic activity was assessed by chemical (Chappelle test), mechanica…
We report inelastic light scattering experiments on FeCr 2 S 4 , which shows colossal magnetoresistance (CMR) effects around T C ≈170 K. Several distinct features have been observed: (i) anomalies in phonon frequencies and linewidths around T C , (ii) the vanishing of one-magnon excitation close to 0.83 T C , and (iii…
By the reaction of new donor molecules, bis(ethylenedithio)tetrathiafulvalenoquinone(-thioquinone)-1,3-dithiolemethides [BEDT-TTFVO (1) and BEDT-TTFVS (2)] with FeX3 (X = Cl, Br) in CS2/CH3CN, 1:1 salts of 1 or 2 with an FeX4- ion (1.FeX4 and 2.FeX4) were obtained as black needle crystals. Their crystal structures are…
The dependence of the optical properties of [C(12)H(12)N(4)O(2)AgPF(6)](2) (dimer-1) and [C(28)H(28)N(6)O(3)AgPF(6)](2) (dimer-2) on the arrangement of the oxime moieties in the molecule and in bulk crystals was investigated by means of time-dependent density functional theory. Dimer-1 with simple pyridine oxime ligan…
Bovine serum albumin (BSA) was reacted with linear and newly synthesized branched oligothiophene N-hydroxysuccinimidyl ester fluorophores (TSEs) in moderately basic carbonate buffer solution. Optically stable BSA-TSE conjugates were obtained with a degree of labeling depending on experimental conditions. Conjugates wi…
The crystallization and melting of emulsified n -octadecane (C 18 ) is monitored by microcalorimetry and by ultrasonic (2.25 MHz) velocity and attenuation measurements. During cooling, the lipid showed two thermal events (a large exothermic DSC peak at 12.8 °C and a smaller one at 7.8 °C) and during heating showed a s…
We report a method to modulate the photoluminescence (PL) of SrTiO 3 (001) at room temperature by fluorhydric (HF) acid etching and Ar + ion bombardment. The PL of the virgin sample is in the blue/green range, which can be enhanced in intensity by a factor of 7.2 after being fully etched in HF acid with the peak shape…
Two novel benzodioxotetraaza macrocycles [2,9-dioxo-1,4,7,10-tetraazabicyclo[10.4.0]1,11-hexadeca-1(11),13,15-triene (H2L1) and 2,10-dioxo-1,4,8,11-tetraazabicyclo[11.4.0]1,12-heptadeca-1(12),14,16-triene (H2L2)] were synthesized by a [1 + 1] crablike cyclization. The protonation constants of both ligands were determi…
Motivated by various spin-1/2 compounds like Cs 2 CuCl 4 or κ - (BEDT - TTF) 2 Cu 2 (CN) 3 , we derive a Raman-scattering operator à la Shastry and Shraiman for various geometries. For T = 0, the exact spectra are computed by the Lanczos algorithm for finite-size clusters. We perform a systematic investigation as a fu…
We show here successful large-area growth of triangular-shaped ZnO nanoplate arrays on silicon substrates and the investigation of their electron field emission properties. The special geometric-shaped nanoplate emitters have a very large surface area for heat dissipation and large field enhancement factors. These lea…
The number k of “internal” layers for the lamellar self-assembled state of a new class of multiblock copolymers A- b -(B- b -C) m - b -B- b -A is determined as a function of m in the strong segregation limit. Here the outer A-blocks are assumed to be considerably longer than the m + 1 blocks of equal length of the (B-…
The pressure-induced Mott transition is investigated in a quasi-two-dimensional molecular conductor, EtMe 3 P[Pd(dmit) 2 ] 2 ( P 2 1 / m ) with a triangular lattice, which shows a valence bond solid state at ambient pressure. Near the critical pressure of the Mott boundary, an insulator-to-metal transition occurs at 1…
Energy minimization and molecular dynamics simulations are used to develop, for the first time, atomistic models of HCl- and HBr-doped conducting polyanilines, in order to study diffusion and adsorption of water vapor in the polymers. Various morphological properties of the polymers are computed, including their pair…
The aim of this study was to evaluate the influence of the coating of polymer implants upon the individual humoral immune response to the polymer matrix. Intramuscular implantation and explantation of samples from three different polyester vascular prostheses coated with collagen, gelatin, or human serum albumin was p…
High-temperature annealing performed at ~1000 °C or higher in an oxidizing atmosphere is a simple technique to significantly modify the as-grown nanostructures of CeO2 films, which are typically granular with high surface roughness. We evaluated the effect of high-temperature annealing on various CeO2 films deposited…
The novel biodegradable poly(epsilon-caprolactone)/titanium dioxide hybrid materials were prepared via in situ sol-gel process of tetrabutyl titanate (TBT) as inorganic precursor in the presence of PCL. The relationships between morphology, microphase separation, crystalline structure, and properties were investigated…
