Five dinuclear lanthanide complexes [Ln(III)(2)(hpd)(6)].solvent, Ln(III) = Eu(III) (1.2MeCN), Gd(III) (2.2MeCN), Tb(III) (3.MeCN.MeOH), Dy(III) (4.2MeCN), Ho(III) (5.2MeCN) and Hhpd (2-Hydroxyisophthaldehyde) were synthesised and structurally and magnetically characterised. X-Ray structural analysis shows all complex…
Nanotechnology has a profound effect on many areas of scientific research. Having grown exponentially, the focus of nanotechnology has been on therapeutic activity, such as cancer treatment. Lipid-based nanocarriers have attracted increasing scientific and commercial attention in the last few years as alternative carr…
At sufficiently low temperatures, disordered ionic materials display the well-known Nearly Constant Loss (NCL) effect, with ionic conductivities becoming approximately proportional to frequency and virtually independent of temperature. There is a broad consensus that the effect is a collective phenomenon, with many in…
First, we succeeded in synthesizing and sintering cordierite ceramics via the solid state reaction route without the melting process by using single phase oxide powders. They are highly pure and fine amorphous silica, α-alumina and magnesia powders. Usually, cordierite ceramics was synthesized by a sol-gel route. Alte…
Vibrational overtone excitation is, in general, inefficiently stimulated by photons, but can under some circumstances be efficiently stimulated by electrons. Here, we demonstrate electron mediated vibrational overtone excitation in molecular collisions with a metal surface. Specifically, we report absolute vibrational…
Recent advances in molecular evolution technology enabled us to identify peptides and antibodies with affinity for inorganic materials. In the field of nanotechnology, the use of the functional peptides and antibodies should aid the construction of interface molecules designed to spontaneously link different nanomater…
Layered double hydroxides (LDHs) intercalated with terephthalate anions represent one of the most studied organo-LDH systems. We have prepared MgAl terephthalate-LDHs using an efficient hydrothermal approach from the respective metal hydroxide precursors. In contrast to terephthalate LDHs prepared by other methods, an…
P-type thermoelectric bismuth telluride nanowires were fabricated by pulsed electrodeposition in anodic aluminium oxide (AAO) membranes. Subsequently, the nanowires were annealed at 423, 523 and 673 K in an inert atmosphere for 4 h. With increasing temperature, it was observed that the Te compound incongruently sublim…
Single-, double- and triple-decker oximato-bridged Ni(ii) clusters based on pyridine-2-amidoxime (H(2)pyaox) have been synthesized and characterized. The decks have the same tetranuclear cationic units [Ni(4)(Hpyaox)(2)(pyaox)(2)](2+) that are stably present in the reaction solution. Magnetic studies show that uncommo…
Colloidal gold particles functionalised with oligoethylene-glycolated disulfide ligands and fluorescent moieties derived from fluorescein isothiocyanate (FITC) have been prepared and studied in aqueous suspension using fluorescence correlation spectroscopy (FCS). FCS probes the dynamics of the particles at the single…
The crystallization of lysozyme with hydrophilic ionic liquid 1,3-butylimidazolium chloride (BBimCl) as an additive was investigated with hanging-drop vapor diffusion crystallization protocol. The elevated threshold to super-saturation caused by the increased solubility of lysozyme in the presence of BBimCl and the sl…
<abstract language="eng">Basic sodalite was successfully synthesized by hydrothermal method using kaolin waste as source of Aluminum and Silicon. This waste is mainly composed by kaolinite and is produced in large amount by kaolin processing industries for paper coating from the Amazon region. Initially, the waste has…
A key feature of planar solid oxide fuel cells (SOFCs) is the feasibility of using metallic interconnects made of high temperature ferritic stainless steels, which reduce system cost while providing excellent electric conductivity. Such interconnects, however, contain high levels of chromium, which has been found to b…
The Langmuir-Schaefer (LS) method has been investigated as a means to control the structure of hybrid organoclay thin films consisting of montmorillonite and dimethyldioctadecylammonium (DODA) cations. We observed a significant modification of the compression isotherms as a function of clay mineral concentration in th…
Magnesium is a light metal that has numerous applications such as for structural material, metallurgical additive in steelmaking, and chemicals. The current dominant route to produce magnesium is via the Pidgeon process in China. This process is unsustainable since it is energy intensive and has a high Global Warming…
The morphology and taxonomy of Aulacoseira taxa, the dominant group of diatoms in a small glacial lake in the Retezat Mts (TDB-1) were studied in specimens from late glacial and Holocene sediments. Seven species were identifi ed and evaluated by light and scanning electron microscopy. The results of these observations…
The optimum ferrite can be obtained through free-microstructural defects where such defects are always encountered in the conventional ferrites often caused by chemical inhomogeneity. In this study, Ni-Zn ferrite was synthesized and fabricated by means of a sol-gel route. Thermal gravimetric analysis (TGA) was used to…
A 2% bandpass filter with an out-of-band rejection in excess of 30 dB was demonstrated experimentally for operation in the C-band (central frequency at 4.5 GHz). Narrow bandwidth and high rejection were achieved by cascading three double split-ring resonators (SRRs) magnetically coupled to a coplanar waveguide (CPW) a…
Generating high density-multiplied nanopatterns through the directed self-assembly of block copolymers (BCPs) will significantly influence the current microelectronics and storage industries. Here, we provide a two-dimensional (2D) sparse rectangle lattice template to direct the equilibrium morphologies of block copol…
The anchoring of rodlike liquid-crystalline molecules at solid surfaces plays an important role in the design of novel nanotechnological devices such as, for example, biosensors. In this work we investigate the impact of various anchoring scenarios on the isotropic–nematic phase transition of weakly anisometric, prola…
