The La(Fe1−xCox)11.44Al1.56 system, with x values of 0, 0.04, 0.08, and 0.12, was investigated for its magnetocaloric potential. For selected values of Co doping, it was possible to cover a wide magnetic ordering temperature range, from 200 up to 370K, and reduce substantially the metamagnetic critical fields. At appl…
The authors have reported a novel Iron loss calculating method based on a loss-map of the magnetic materials. A distinctive feature of this method is that the Iron loss on the Inductors can easily be calculated In many kinds of converters. In this paper, a novel Iron loss calculating method of the ac filter inductor o…
A new class of bio-nanocomposites based on hybrid gelatin-perovskite hydrogels was prepared by mixing exfoliated perovskite-tetraalkylammonium species in aqueous suspensions with gelatin solutions. Colloidal nanosheets derived from the CsCa2Nb3O10 layered perovskite re-stacked in the gelatin solutions give bio-nanocom…
Abstract A coordination host recognized various aromatic peptides containing Trp and Tyr residues in a highly sequence-selective fashion. For example, two similar hexa-peptides, Ac-Ser-Gly-Ala-Trp-Trp-Ala-NH2 and Ac-Ala-Trp-Trp-Ala-Gly-Ser-NH2, were selectively discriminated by the restricted inner space of coordinati…
Abstract Several conjugated polymers containing phenothiazine moieties in the main chain were synthesized by Knovenagel or Wittig condensations. The polymers were identified and characterized by 1 H‐NMR, IR, gel permeation chromatography (GPC), thermogravimetric analysis (TGA), UV‐vis and fluorescent (FL) spectra. Res…
The low fluid throughput in electrospinning may limit the industrial use of single needle system. To meet high liquid throughput requirements and uniform fibers, a special aligned multiple jets setup has been designed in this paper. The needles have been disposed as a regular hexagon. A 7 cm diameter iron ring has bee…
The stress relaxation behavior of four kinds of knitted fabric under a constant strip biaxial strain applied instantly was estimated in the rectangular coordinate system rotated by arbitrary angle τ from the coordinate system along the structural principal axis direction. The stress relaxation curves for the four kind…
Using a discrete model for the synclinic SmC∗ and the anticlinic phases we give a theoretical explanation for the fact that the helix twisting sense reverses at a transition between these phases (direct transition or via the so‐called chiral smectic C ‘subphases’) and we derive an explicit expression for the helical p…
One of the major problems in building a future fusion power station is the development of suitable structural materials. These materials will be exposed to high energy neutron bombardment, with consequent changes in their mechanical properties – embrittlement, hardening and swelling, for example. A missing link in mod…
In this paper we investigate the model for the motion of a contact line over a smooth solid surface developed by Shikhmurzaev, [24]. We show that the formulation is incomplete as it stands, since the mathematical structure of the model indicates that an additional condition is required at the contact line. Recent work…
We’ve built this digital research platform to provide academics everywhere with fast, stable and secure digital access to our library of over 110,000 scholarly books and 800,000 journal articles. We’ve tested the platform in close cooperation with leading academic institutions. If you have any questions or you notice…
Abstract Field‐emission (FE) electron and ion microscopies (FEM and FIM), I ( V ) characteristics, and FE energy spectroscopy (FEES) measurements have been made on individual multiwalled carbon nanotubes (MWNTs) at various stages of their evolution under various thermal and field treatments. Before the highest tempera…

Abstract The Na–H system thermodynamic properties were assessed using Gibbs free energy model parameters obtained from best fit optimizations to combined experimental and first-principles predicted data. The first-principles finite temperature thermodynamic property predictions, based upon density functional theory gr…
In this work we report on our algorithm for generating 3–D virtual structures resembling un-bonded fibrous webs. The paper discusses short and infinitely long fibers, each emulating a category of nonwoven fibrous medium. The structure Solid Volume Fraction (SVF), being the most important characteristic of a fibrous po…
SUMMARY Fragilaria rumpens (Kütz.) G. W. F. Carlson is assumed to be a cosmopolitan species, and is often reported from ponds and lakes. Nevertheless, this species is similar to both Fragilaria capucina Desm. and Fragilaria vaucheriae (Kütz.) J. B. Petersen and, as a consequence, the taxonomy of all three species has…
Chitosan is a biopolymer derived from chitin in crustacean shells. Over the past decade it has been studied as an environmentally benign wood-protecting agent. It is assumed to act as a fungi-stat against a wide range of fungi and even as a fungicide at higher concentrations. This study investigated the properties of…
The early phase of severe accidents in VVER reactors was simulated in the CODEX (COre Degradation EXperiment) facility with electrically heated fuel rod bundles. The selected test conditions and applied measurement techniques made possible the observation of some specific phenomena, such as the protective role of oxid…
This article briefly reviews the progress in ultraviolet (UV) or photoinitiated grafting for improving the adhesion property of polyethylene (PE). The first part involves the progress in the fundamental study of UV grafting, including the grafting methods, the photoinitiators, and the self-initiated grafting; the seco…
Porous and dense silicon nitride films with low (1.58) and high (1.88) refractive indices were prepared by using successively microwave and radio frequency (rf) plasma-enhanced chemical vapor deposition. Surface treatments were performed on porous layers using argon and nitrogen rf plasmas in order to densify and flat…
