The microporous metal−organic framework Ni 2 (dhtp) (H 4 dhtp = 2,5-dihydroxyterephtalic acid) is a 3D network that maintains crystallinity and porosity after solvent removal. A mild thermal treatment in high vacuo at 393 K removes completely water allowing to obtain a MOF material with honeycomb structure able to str…
The reaction of bromo-2,4,6-triphenylbenzene with activated magnesium in THF yielded the Grignard reagent [(thf)(2)Mg(Br)-C(6)H(2)-2,4,6-Ph(3)] (1) with a Mg-C bond length of 214.8(3) pm. A similar reaction of bromo-2,4,6-triphenylbenzene with activated calcium led to an "inverse" sandwich complex [(thf)(3)Ca{mu-C(6)H…
A new cross-linkable regioregular poly(3-(5-hexenyl)thiophene) (P3HNT) was synthesized via the Grignard metathesis route for the purpose of stabilizing the film morphology in polymer photovoltaic cells. Bulk heterojunction photovoltaic cells with P3HNT and (6,6)-phenyl C 61 butyric acid methyl ester (PCBM) showed init…
In this work, LiFePO 4 with hierarchical microstructures self-assembled by nanoplates has been successfully synthesized by using poly(vinyl pyrrolidone) (PVP) as the surfactant in a benzyl alcohol system. The resulting dumbbell-like LiFePO 4 microstructures are hierarchically constructed with two-dimensional nanoplate…
Ordered hierarchical nanostructured carbon (OHNC) has been fabricated through inverse replication of silica template and explored for the first time to support high loading of Pt nanoparticles as cathode catalyst in proton exchange membrane fuel cells (PEMFC). The superb characteristics such as ordered hierarchical na…
Large, larger, ... Replacement of 1,4-benzenedicarboxylate by 2,6-naphthalenedicarboxylate in the MIL-101 structure leads to an isoreticular mesoporous framework containing cages with diameters of 39 and 46 A. High-throughput methods are employed to determine appropriate reaction conditions. The microcrystalline compo…
Breast cancer metastasis suppressor 1 (BRMS1) is a predominantly nuclear protein that differentially regulates expression of multiple genes, leading to suppression of metastasis without blocking orthotopic tumor growth in multiple human and murine cancer cells of diverse origins. We hypothesized that miR-146 may be in…
A brief and systematic overview of recent advances in understanding the mechanism of mechanochemical cocrystallization at macroscopic (bulk phase transformations) and microscopic levels (molecular recognition) is given. The review particularly addresses neat and liquid-assisted grinding approaches to cocrystal formati…
Here we explore an electrochemical route to prepare ternary Zn 1− x Cd x O (0 < x < 0.15) rod-like nanoparticle aggregates in a solution of ZnCl 2 + CdCl 2 + KCl at a temperature of 75 °C. The longest rod-like nanoparticle aggregates of 10−15 μm can be achieved. X-ray energy dispersive spectroscopy (EDS) results demon…
Abstract A new, well‐designed type of micron‐sized hollow copper spheres was synthesized in this article. The process was performed using ZSM‐5 molecular sieve as a template. It has the prominent advantage in that the various stages of pretreatment for the core material can be omitted because of the inherent nature of…
A new approach to promoting and controlling polymer surface functionalization with acidic or basic polar functional groups is demonstrated and evaluated. Blended polymer films were annealed under pH-buffered conditions, and polar end-functional groups were found to promote surface segregation of the functional polymer…
Abstract SAM im Glashaus: Glasverkapselte selbstorganisierte Monolagen (SAMs) auf durchstimmbaren Gold/Silber‐Nanoschalen wurden als Markierungsreagens für die oberflächenverstärkte Raman‐Streuung (SERS) eingesetzt. Dieses Konzept vereint die spektroskopischen Vorteile einer maximalen Oberflächenbedeckung und der einh…
The effect of substituent group on the binding energy of phosphonic and carboxylic acids to the Cd 6 Se 6 cluster was studied within density functional theory. The binding energies of 12 para-substituted phenylphosphonic acids, 5 para-substituted benzoic acids, and 5 para-substituted benzoates to the Cd 6 Se 6 cluster…
Abstract We report uncertainties in X‐ray photoelectron spectroscopy (XPS) intensities arising from commonly used methods and procedures for subtraction of the spectral background. These uncertainties were determined from a comparison of XPS intensities reported by volunteer analysts from 28 institutions and the corre…
Abstract In this study, electrochemically roughened gold is modified with underpotential deposition (UPD) silver to investigate the effects on enhancements in the intensity and the thermal stability of surface‐enhanced Raman scattering (SERS). The SERS of Rhodamine 6G (R6G) adsorbed on the UPD Ag‐modified Au substrate…
The catalyst deactivation behavior of rhodium-coated foam monolith was systematically investigated in order to understand the means to improve the durability of the rhodium catalyst applied for catalytic partial oxidation of methane (CPOM). The overall CPOM reactions on the foam structured catalyst have been acknowled…
V 2 O 5 nanofibers and three vanadium-based oxides with different structures (MnV 2 O 6 nanosheets, FeVO 4 ·0.92H 2 O nanoneedles, and Sn 2 VO 6 ·0.78H 2 O nanoparticles) were synthesized via a hydrothermal method. Field-emission scanning electron microscopy, transmission electron microscopy, electron diffraction, ene…
The active sites of mononuclear molybdenum-containing enzymes contain a low-symmetry Mo(V)-dithiolene intermediate whose structure can be probed using electron paramagnetic resonance (EPR). The relationship between experimental EPR spectra and the electronic and geometric structure of the active site can be difficult…
Abstract The effects of C cation and S cation doping on the electronic structures and optical properties of SrTiO3 are investigated by density function theory (DFT) calculations. The calculated results reveal that the top of the valence band is predominately made up of the O 2p states for the pure SrTiO3. When SrTiO3…
The binodals and the nonergodicity lines of a binary mixture of hard-sphere-like particles with a large size ratio are computed for studying the interplay between dynamic arrest and phase separation in depletion-driven colloidal mixtures. Contrary to the case of hard core plus short-range effective attraction, physica…
