In this article, we report the synthesis of ultra-long carbon nanotubes (CNTs) by thermal chemical vapour deposition method. Ultra-long, individual and aligned CNTs were directly grown on a flat silicon substrate. The orientation of the nanotubes was found parallel to the gas flow direction. The ultra-long CNTs were g…
Abstract A polar indium thioantimonate, namely [Ni(en) 3 ][InSbS 4 ] ( 1 ) (en = ethylenediamine), has been synthesized under solvothermal conditions. Its structure features a left‐handed helical anionic chain of [InSbS 4 ] n 2 n – moieties built upon trinuclear heterometallic clusters of {In 2 SbS 8 } as secondary bu…
An intense and broad visible photoluminescence (PL) band was observed at room temperature in short-range disordered BaWO 4 crystals. The scheelite crystalline BaWO 4 powders prepared by the polymeric precursor method and annealed at different temperatures were structurally characterized by means of X-ray diffraction a…
In this work, the pore size-dependent PPL diffusion and protein distribution in SBA-15 support have been investigated in detail by confocal laser scanning microscopy (CLSM) and X-ray diffraction (XRD) observations in combination with hindered diffusion simulation, intraparticle diffusion analysis, and apparent kinetic…
The effective thermal conductivity ( k e ) of a MmNi 4.5 Al 0.5 hydride powder bed was measured using an one-dimensional steady-state axial heat transfer comparative method. The experiments showed that k e lies between 0.1 and 1.2 W/m K in the pressure and the temperature ranges of 0–50 bar and 0–100 °C, respectively.…
Abstract New low‐melting organic–inorganic glassy polymers containing phosphorus and silicon are synthesized by the reaction between phenylphosphonic acid and methyltrichlorosilane or methyltriethoxysilane. They possess both low‐softening points and high onset decomposition temperatures, which are favorable for prepar…
Squaraines have been known for many decades as very stable and versatile vis-NIR absorbing dyes. They have found applications for example as sensitizers in organic photovoltaics and photodetectors. The most common squaraine structure is the 1,3-regioisomer. Their 1,2-regioisomers are seldom mentioned and unanimously r…
Eleven new, stable, push-pull systems that feature 4,5-bis[4-(N,N-dimethylamino)phenyl]imidazole and 4,5-dicyanoimidazole as the donor and acceptor moieties and the systematically extended and varied π-linker were prepared and investigated. Evaluation of the measured UV/Vis spectra, electrochemical data (cyclic voltam…
The adhesion process of osteoblast-like cells on hydroxyapatite (HAp) and oxidized polystyrene (PSox) was investigated using a quartz crystal microbalance with dissipation (QCM-D), confocal laser scanning microscope (CLSM), and atomic force microscope (AFM) techniques in order to clarify the interfacial phenomena betw…
This work reports a complete structural characterization of hydrothermal synthesized tubular Ni 3 Si 2 O 5 (OH) 4 correlating experimental X-ray diffraction (XRD) and transmission electron microscopy (TEM) results with theoretical nanotubular model characteristics. Nanotubes of single and multiple layers were evidence…
The high‐pressure Raman studies of pure, Yb‐modified, protonated and non‐protonated SrZrO 3 dense ceramics were performed between 0.1 and 40 GPa using a diamond anvil cell. Lanthanide‐modified, protonated SrZrO 3 perovskites are potential materials for electrolytic membrane in fuel cells and electrolysers working at m…
In the solid state, MnF(salen) forms chains wherein fairly linear fluoride bridges between high-spin Mn(III) centers are observed. We interpret the magnetic properties of these chains by use of the classical Fisher model and by use of the high-temperature expansion approach, as well as by exact matrix diagonalization…
BACKGROUND: Over the past several centuries, chemistry has permeated virtually every facet of human lifestyle, enriching fields as diverse as medicine, agriculture, manufacturing, warfare, and electronics, among numerous others. Unfortunately, application-specific, incompatible chemical information formats and represe…
The box model, originally introduced to account for the nonresonant hole burning (NHB) dielectric experiments in supercooled liquids, is compared to the measurements of the third harmonics P(3) of the polarisation, reported recently in glycerol, close to the glass transition temperature T(g) [C. Crauste-Thibierge, C.…
In the present work, the promotion effects by doping metals on K 2 Ti 2 O 5 or by combining an additional NO oxidation catalyst are studied in detail for soot oxidation. The synthesized catalysts are characterized by X-ray diffraction. The promoting effects of NO and NO 2 on soot oxidation were examined on both K 2 Ti…
We use ab initio density functional calculations to investigate the structural stability and vibrational spectra of small boron aggregates in different charge states. In search of candidates for the largest stable 2D boron aggregates, we focus on systems with one atom less than ${\mathrm{B}}_{20}$ clusters with confir…
A fundamental Single-Event MicroKinetic (SEMK) model for the hydrogenation of aromatic components on a Pt catalyst has been developed. It is based on the Horiuti-Polanyi mechanism considering atomic hydrogen addition steps to the (partially hydrogenated) aromatic species on the catalyst surface. The reaction network u…
Bifunctional core–shell–corona particles that bore both fluorinated units and hydroxyl groups in the corona were synthesized. The core particles were prepared from monomer methyl methacrylate (MMA) and cross-linker ethylene glycol dimethacrylate (EGDMA). The shell was grown from MMA, EGDMA, and HEA-Cl [2-(2′-chloropro…
The advanced oxidation processes of sonolysis (213 kHz), photocatalysis, and a hybrid combination of both (sonophotocatalysis) have been used in the degradation of a representative aromatic carboxylic acid, p-chlorobenzoic acid (PCBA), in ambient air saturated aqueous solutions. The formation of degradation products w…
Selective and slow: The effects on the photophysics of a single salicylideneaniline molecule, induced by confinement in an all-organic, weakly interacting molecular capsule of a matching size, are studied by time-resolved spectroscopy. The capsule acts efficiently to select only one deactivation pathway after photoexc…
