Motivated by recent experiments on isovalent-doped 1111 iron-based superconductors ${\text{LaFeAs}}_{1\ensuremath{-}x}{\text{P}}_{x}{\text{O}}_{1\ensuremath{-}y}{\text{F}}_{y}$ and the theoretical study that followed, we investigate, within the five-orbital model, the correlation between spin fluctuations and the supe…
Fabric bagging is one of the important phenomena that determine the permanent 3D deformation of fabric under the applied loads. This study focused on dynamical bagging of knitted fabrics and factors affecting it to increase transformation of fabrics preform into various structural shapes through net-shape fabrications…
ABSTRACT This study focused on the fabrication and mechanical evaluation of nonwoven reinforced flexible polyurethane foam composites. Effects of perforation ratio, aperture size, and perforation depth on bursting and low‐velocity impact responses of perforated composite panels were investigated. The nonwoven fabric u…
An ab initio derived transferable polarizable force-field has been developed for Zinc sulphide (ZnS) nanoparticle (NP) and ZnS NP-PMMA nanocomposite. The structure and elastic constants of bulk ZnS using the new force-field are within a few percent of experimental observables. The new force-field show remarkable abili…
A set of titanium dioxide thin films have been deposited on fused silica substrates by the novel asymmetric bipolar pulsed dc reactive sputtering technique using different oxygen partial pressures in the sputtering ambient in the range of 0%–21%. For investigating long-range structural properties of the samples…
Investigation of novel fast ion-conducting materials requires an accurate description of the ionic diffusion. The tiling method proposed by Blatov and coworkers, based on geometric characteristics, is a viable alternative to molecular dynamics simulations, allowing us to build models of the pathway system in crystal s…
In-stent restenosis (ISR) is one of the major factors affecting long-term outcomes of percutaneous coronary interventions. Vascular endothelial growth factor (VEGF) has been hypothesized to have a positive role in preventing ISR, however, this remains controversial. The aim of the present study was to assess whether n…
Titanium–tantalum shape memory alloys (SMAs) are promising candidates for actuator applications at elevated temperatures. They may even succeed in substituting ternary nickel–titanium high temperature SMAs, which are either extremely expensive or difficult to form. However, titanium–tantalum alloys show rapid function…
The depolarization effect at the interfaces between PbZr0.2Ti0.8O3 and SrRuO3 film layers and 180° domains in the PbZr0.2Ti0.8O3 film layer are characterized, demonstrating that the polarization bound charges induced at the interfaces are not completely compensated by the charge carriers in the SrRuO3 electrode layer.…
Owing to their unique and indispensable physical, chemical, electrical/ electronic, and mechanical properties, graphene and conducting polymers have become attractive materials in all fields of science and technology. This mini-review provides a comprehensive summary on the cutting-edge sensor technologies based on gr…
Abstract The chemical combination of completely condensed polyhedral oligomeric silsequioxanes and Eu 3+ ions has allowed the preparation of a novel robust mesoporous silica (Eu‐MesoPOSS) with interesting luminescent properties and good hydrothermal and photobleaching stability. These properties make Eu‐MesoPOSS a pot…
Abstract To improve the biocompatibility and operational safety of titanium implants made of Ti6Al4V alloy, anodizing is applied. The anodizing process allows adjustment of the highly biocompatible oxide level on the metallic surface. However, little attention is paid to the influence of the layer thickness on the con…
The specific heat, the susceptibility under pressure, and the dielectric constant were measured for single crystals ${\mathrm{Y}}_{1\ensuremath{-}x}{\mathrm{La}}_{x}{\mathrm{TiO}}_{3}$. The observed ${T}^{2}$-dependent specific heat at low temperatures for $0.17\ensuremath{\le}x\ensuremath{\le}0.3$ samples shows a spi…
Investigations of temperature behaviour of the mean refractive index n, ordinary n o and extraordinary n e refractive indices, and birefringence Δn have been carried out for three homologues of 4-n-alkyl-4’-cyanobiphenyls (n = 8, 10, 12). The principal polarizabilities α 0 and α e , effective geometry parameter α eg a…
The most plentiful natural biopolymer chitin and chitosan have become center of attraction of all party because of an unusual combination of biological activities, mechanical and physical properties. The several chemical modifications such as oligomerization, alkylation, quternization, enzymatic modifications, and gra…
Summary The physical, optical, antimicrobial and antioxidant properties of jellyfish protein ( JFP ) films with added transglutaminase ( TG ase) and wasabi extract ( WE ) were studied. Among the plasticisers, 30% sorbitol was the most desirable. The optimal physical properties of the JFP films were obtained when 15 U…
A reflection theory is employed to analyze a single-layered metamaterial absorber. With the necessary conditions for zero reflection, the permittivity and permeability as functions of absorptivity were obtained, which are suitable for analyzing the absorption properties of single-layered metamaterial absorber at both…
New opportunities for studying (sub)microcrystalline materials with small unit cells, both organic and inorganic, will open up when the X-ray free electron laser (XFEL) presently being constructed in Switzerland (SwissFEL) comes online in 2017. Our synchrotron-based experiments mimicking the 4%-energy-bandpass mode of…
A spectroelectrochemical approach for the fundamental analysis of the cathodic corrosion behavior of hot‐formed zinc alloy coated steel based on the in‐situ combination of inductively coupled plasma‐optical emission spectroscopy (ICP‐OES) is presented. Complementary to the microscopic information on the alloy dissolut…
The study aims at a comprehensive surface characterization of untreated and oxygen plasma-treated silk fibroin with a particular focus on phenomena relevant to biointeraction and cell adhesion. For that purpose, a range of advanced surface diagnostic techniques is employed to thoroughly investigate well-defined and es…
