Molecular magnetism is considered an area where magnetic phenomena that are usually difficult to demonstrate can emerge with particular clarity. Over the years, however, less understandable systems have appeared in the literature of molecular magnetic materials, in some cases showing features that hint at the spontane…
EPS off-grade is commonly known as waste in the manufacturing process of Expanded Polystyrene (EPS). It is worthwhile to recover such waste by improving its properties. However, blowing agent used in the EPS would be a drawback in the recovering process. Our research implemented the improvement by the addition of impa…
Reaction of Fe3(CO)12 with 1,2-dithiolene HSC6H2Cl2SH affords a mixture of complexes [Fe2(CO)6(μ-SC6H2Cl2S)] 1, [Fe2(SC6H2Cl2S)4] 2 and [Fe3(CO)7(μ3-SC6H2Cl2S)2] 3. In the course of the reaction the trimetallic cluster 3 is first formed and then converted into the known dinuclear compound 1 to afford finally the neutr…
We have studied the self-assembly of PS-PMMA block copolymers by means of SCFT simulations in elongated templates and established commensurability windows for the formation of single rows of two and three cylindrical VIAs. Our results indicate that VIAS with increasing CD form inside templates of increasing dimensions…
Effect of annealing temperature and thin film thickness on properties of Pb(Zr0.53Ti0.47)O3(PZT) thin film deposited via radiofrequency magnetron sputtering technique onto Pt/Ti/SiO2/Si substrate was investigated. Average grain sizes of the PZT thin film were measured by atomic force microscope; their preferred orient…
Ti 3+ induced by F-dopants plays an important role in enhancing interaction between gas molecules and TiO 2 surfaces.
Aminoguanidine lanthanide thiodipropionate hydrates of composition [Ln(Agun)2(tdp)3·nH2O], Agun = Aminoguanidine, tdp = thiodipropionic acid, where Ln = La, Pr, Nd and Sm if n = 2, have been prepared and characterized by physic-chemical techniques.
We consider an optimal control problem for the interface in a two-dimensional multiphase fluid problem. The minimization functional consists of two parts: the $L^2$-distance to a given density profile and the interfacial length. We show existence and derive necessary first order optimality conditions for a correspondi…
The effect of Sn 2+ on the anodic dissolution of nickel was investigated in deaerated 0.2 M HClO 4 solution containing Sn 2+ at room temperature. It has been found that the addition of 10 −3 M Sn 2+ inhibits completely the anodic dissolution of Ni. In contrast, tin itself is not passivated in 0.2 M HClO 4 irrespective…
A series of highly fluorescent conjugated anthracene dendrimers having monomeric emission profile, but still exhibiting fast exciton depolarisation, are here presented.
In this paper we investigate the possibility to apply the concepts of non-specific intermolecular interactions and dispersive local field effect approach for study of the influence of interactions of metal nanoparticles with matrix molecules on the spectral characteristics of composites. The effect of intermolecular (…
Properties of hemp fibre reinforced unsaturated polyester composites following exposure to accelerated weathering conditions have been studied. Exposure to ultraviolet (UV) radiation and UV radiation plus condensation resulted in immediate loss in weight which stabilised following prolonged exposure times. The same ex…
PURPOSE: As stereotactic radiotherapy (SRT) becomes widespread, precise information including number, location, and margin of lesions is required when magnetic resonance (MR) imaging of brain metastasis is performed. We compare methods using 2 separate injections and a single injection for the administration of a doub…
Coating using magnetically enhanced plasma deposition gives smooth diamond-like carbon films that increase hardness and wear resistance of nanostructures.
This article reports a systematic investigation of the synthesis and structural characterization of composite CAZO [(Zn 1−x−y Co x Al y O; x = 0.04, 0.03, 0.02; y = 0.01, 0.02, 0.03)] nanoparticles from combustion.
The cross-plane thermal conductivity of amorphous Si/Si 0.75 Ge 0.25 multilayer films with Au-interlayers prepared by magnetron sputtering was successfully measured using a differential technique at room temperature. Though gold has great thermal conductivity, the samples possess a thermal conductivity of 0.53 W/mK, w…

Semiconductor sensitized NiO photocathodes have been fabricated by successive ionic layer adsorption and reaction (SILAR) method depositing CdTeO3 quantum dots onto mesoscopic NiO films. A solar cell using CdTeO3 deposited NiO mesoporous photocathode has been fabricated. It yields a photovoltage of 103.7 mV and a shor…
Liquid-core nanoparticles are promising candidates for targeted ultrasound-controlled therapy, but their acoustic detection remains challenging. High-frequency (20 to 40 MHz) tone burst sequences were implemented with a programmable ultrasound biomicroscope to characterize acoustic response from perfluorooctyl bromide…
Silver (Ag) nanoparticles were prepared by the polyol process using tripropylene glycol, 3-ethyl-3-oxetanemethanol, and polycaprolactone triol as the reducing agents and poly(vinylpyrrolidone) (PVP) with average molecular weights (Mw) of 10 000, 55 000, and 1 300 000 as the protective agent, respectively. It was found…
