The first members of the classes of the organorhenium(VII) oxides and organomolybdenum(VI) oxides were described during the 1960s and 1970s. However, despite the fact that methyltrioxorhenium(VII)(MTO) is probably the best examined organometallic oxide known, many of its derivatives as well as the Mo congeners were no…
Single-crystal Cr2O3 with regular mesopores has been synthesized using mesoporous silica KIT-6 as a template and characterized by using XRD, HRTEM and nitrogen adsorption/desorption.
A high-performance solid oxide fuel cell (SOFC) single cell with (LSGM) thin film ( thick) as electrolyte, working at 400-700°C, was demonstrated. A (SDC) interlayer (400 nm thick) was introduced between the anode substrate of and the LSGM thin film to prohibit the reaction between LSGM and NiO and also to promote the…
The elusive biaxial nematic liquid crystal phase was recently discovered in a family of substituted oxadiazoles. Our investigations of these materials show that the achiral biaxial nematic phase can segregate into chiral domains of opposite handedness, thereby demonstrating that the liquid-like nematic phase exhibits…
A dramatic change of solid-state fluorescence properties triggered by molecular arrangements of anthracene moieties was obtained by using organic salts of ADS with primary amines, indicating that modification of the amines enables us to tune the properties.
Ag-polypyrrole nanocables were fabricated in aqueous solution at room temperature through a redox reaction between silver nitrite and pyrrole, using poly(vinyl pyrrolidone)(PVP) as assistant agent.
Saccharin, acting as a weak acid, forms salts with basic APIs and these salts have the desirable property of enhanced water solubility.
The microstructure and mechanical properties of thermo-mechanically treated Cu-2.0mass%Ni-0.5mass%Si alloys with and without 0.1mass%Mg have been investigated. The Mg addition increases the formation rate of disk-shaped Ni2Si particles. The Mg addition produces higher strength and resistance to stress relaxation. The…
Novel large pore cage type mesoporous carbon molecular sieves, carbon nanocage, (CKT) with various pore diameters have been prepared from KIT-5 as inorganic templates synthesized at different temperature. It has been found that the textural parameters of the above mesoporous carbons can be easily tuned by a simple adj…
A one-step, room-temperature method is described to chemically synthesize bulk quantities of microns long, 100-180 nm diameter nanofibers of electrically conducting poly(3,4-ethylenedioxythiophene)(PEDOT) in the form of powders, or as optically transparent, substrate-supported films using a V2O5 seeding approach.
Rapid and highly sensitive detection of duplex dye-labelled DNA sequences in a PDMS microfluidic channel was investigated using confocal surface enhanced Raman spectroscopy (SERS). This method does not need either an immobilization procedure or a PCR amplification procedure, which are essential for a DNA microarray ch…
High-performance (LSM) cathodes for intermediate temperature solid oxide fuel cells were fabricated by the ion impregnation of oxygen ion conducting Gd-doped (GDC) oxide. The microstructure of the GDC-impregnated LSM electrode was characterized by the uniform dispersion of very fine GDC particles in the LSM porous fra…
We show that direct coupling of a dye-labelled DNA (acceptor) to a quantum dot (QD) donor significantly reduces the donor-acceptor distance and improves the FRET efficiency: a highly efficient FRET (approximately 88%) at a low acceptor-to-donor ratio of 2 has been achieved at the single-molecule level.
Microporous fibrous membranes were prepared from poly(vinylidenefluoride- co -hexafluoropropylene) P(VdF-HFP) solutions in an acetone/ N,N -dimethylacetamide mixture using the electrospinning method. Varying the P(VdF-HFP) polymer concentration in electrospinning can easily control the pore size and the porosity of th…
Groundwater discharge areas in boreal forest ecosystems can potentially be areas where Fe and Al accumulate in the forest floor and affect the solubility of P. This study was conducted to determine phosphate sorption properties using humus soils containing high native amounts of Al and Fe. Humus soils were collected f…
The main issue of Cu metallization is the electromigration of Cu through the interface between Cu and the barrier or capping layer. To improve electromigration resistance at the Cu and barrier metal interface, insertion of a glue layer which enhances the adhesion of Cu onto the under layer may be effective. The wettab…
This review focuses on some aspects of organic-inorganic hybrid materials prepared by the sol-gel method. This field has been studied worldwide as one of the nanotechnologies, and is now of current interest for both organic and inorganic scientists. The elaboration of organic–inorganic polymer hybrid materials using t…
The cuticules (shells) of the woodlice Porcellio scaber and Armadillidium vulgare were analysed with respect to their content of inorganic material. It was found that the cuticles consist of crystalline magnesium calcite, amorphous calcium carbonate (ACC), and amorphous calcium phosphate (ACP), besides small amounts o…
Rich properties of systems with strongly correlated electrons, such as transition metal (TM) oxides, is largely connected with an interplay of different degrees of freedom in them: charge, spin, orbital ones as well as crystal lattice. Specific and often very important role is played by orbital degrees of freedom. The…
The effect of the size, shape, and structure of gold and silver nanoparticles on the dependence of their extinction and integral scattering spectra on the dielectric environment has been investigated. Calculations were performed using the Mie theory for spheres and nanoshells and the T -matrix method for chaotically o…
