The magnetoelectric (ME) effect in composite materials results from the combination of the magnetostrictive effect and the piezoelectric effect via elastic interaction. This work focuses on the modeling of multilayer structures under dynamic excitation. The calculated ME coefficient versus frequency shows the enhancem…
The fatty acid composition of soybean oil is presented in Table Unfortunately, the internal 1,2 disubstituted nonconjugated double bonds are of low reactivity and polymerize with difficulty There are two methods for polymerization of soybean oil on a larger scale, both methods being radical initiated processes: therma…
Unlike the ferropnictide superconductors, which crystallize in a tetragonal crystal structure, binary FeAs forms in an orthorhombic crystal structure, where the local atomic environment resembles a highly distorted variant of the FeAs${}_{4}$ tetrahdedral building block of the ferropnictide superconductors. However, l…
The surface of polyethylene terephthalate (PET) films was irradiated using KrF excimer laser (λ = 248 nm) with different number of pulses at constant repetition rate. The adhesion behavior of L-929 fibroblast cells on the irradiated surface was investigated. The changes in films' morphology were characterized by atomi…
Measurements of optical transmission in the visible spectral range of N + irradiated thin films of multiwall carbon nanotubes (MWCNTs) at various doses prepared by a vacuum filtration method are reported. An increase in optical transmission was observed corresponding to increase in N + ion doses. Changes in Raman spec…
Abstract Manganese oxide nanocrystals are combined with aluminum oxide nanocrystals to improve their crystallinity via calcination without a significant increase of crystal size. A nanocomposite, consisting of two metal oxides, can be synthesized by the reaction between permanganate anions and aluminum oxyhydroxide ke…
Geometry, hardness and size can be considered the most important characteristics affecting the wear rate caused by abrasive particles. The combined effect of these characteristics on wear has not yet been modeled as a whole. One particular model, proposed by Rabinowicz et al. (1961), involves a single particle being c…
This paper presents an improved integration-type E&S modeling for applications under high magnetic flux density conditions. In the conventional integration-type dynamic E&S modeling, we assumed linear increment of higher harmonic components including in the magnetic field strength waveforms versus the magnetic flux de…
Two new polytungstate-based compounds, [Co(mbpy)3][W6O19] (1) and [Ni(mbpy)3]2[VW12O40] (2) (mbpy = 4,4′-dimethyl-2,2′-bipyridyl), have been hydrothermally synthesized and characterized by IR spectroscopy, TG analysis, and single-crystal X-ray diffraction. Single crystal X-ray structural analyses demonstrate that the…
Having many advantages compared to classic wire wound technology; planar magnetic components are largely used. Modeling tools are required to help designers for less time consuming conception. Nevertheless, number of adapted modeling solutions is limited by the complexity of such geometries. The determination of appro…
The thermal conductivity \ensuremath{\kappa} of the ferroelectric, paraelectric, and incommensurate phases of polycrystalline Sn${}_{2}$P${}_{2}$S${}_{6}$ has been measured in the 0.1--0.7 GPa range. The thermal conductivity \ensuremath{\kappa} of the ferroelectric phase decreases with increasing pressure $p$. This un…
2.1 Linear unbranched' structures 2.1.1 Wood: Hierarchical structuring and microfibril angle There exist numerous applications in which wood, wood pulp and natural fibers are used as components in the manufacturing of composites (e.g., Gindl & Jeronimidis 2004) for improving mechanical, thermal or other beneficial pro…
In this paper, the cisplatin composite micro/nanofibers were prepared by electrospinning. Average diameter of the typical products was about 700 nm, and cisplatins were incorporated in biodegradable poly (L-lactic acid) fibers. The controlled release of cisplatin can be gained for long time. The possible mechanisms of…
This paper presents a generalized Chua-type vector hysteresis model to describe both the static and dynamic vector magnetic properties of electrical steel sheets. The proposed model takes into account all significant harmonic components of the measuredH-waveforms, thus it provides precise prediction ofH-waveforms even…
Radiation damage in macromolecular crystallography has become a mainstream concern over the last ten years. The current status of research into this area is briefly assessed, and the ten new papers published in this issue are set into the context of previous work in the field. Some novel and exciting developments emer…
Nanocrystalline diamond (NCD) thin films are being progressively more employed in different applications. However, the current understanding of their growth mechanisms, which becomes important to properly tune their properties, is still very limited. In this context, we have studied by atomic force microscopy the grow…
We describe the application of quantitative evaluation of mineralogy by scanning electron microscopy in combination with techniques commonly available at hard X-ray microprobes to define the mineralogical environment of a bauxite residue core segment with the more specific aim of determining the speciation of trace me…
Learning from Biosilica: Nanostructured Silicas and Their Coatings on Substrates by Programmable Approaches
By means of an electron diffraction technique, crystal-lattice modulations were investigated for a hexaferrite, Ba${}_{0.5}$Sr${}_{1.5}$Zn${}_{2}$Fe${}_{12}$O${}_{22}$, showing a helimagnetic order below ${T}_{\mathrm{N}}=320$ K. We observed a lattice modulation with a wave vector $\text{Q}=(0,0,3\ensuremath{\delta})$…
The first high nuclearity, mixed-metal Bi(III)/Mn(IV) and Bi(III)/Mn(III) complexes are reported. The former complexes are [Bi(2)Mn(IV)(6)O(9)(O(2)CEt)(9)(HO(2)CEt)(NO(3))(3)] (1) and [Bi(2)Mn(IV)(6)O(9)(O(2)CPh)(9)(HO(2)CPh)(NO(3))(3)] (2) and were obtained from the comproportionation reaction between Mn(O(2)CR)(2) a…
