To take account of the uncertainties introduced on the soft magnetic materials properties (magnetic behavior law, iron losses) during the manufacturing process, the present work deals with the stochastic modeling of the magnetic behavior law B-H and iron losses of claw pole stator generator. Twenty-eight samples of sl…
Functional PLA scaffolds are created with single component, core-sheath, or porous fiber morphology and doped with TCP nanoparticles to study the release profiles for use in bone tissue engineering applications. Pharmacokinetic analyses are performed for the three different nanofibrous structures after doping with TCP…
Tetraoctylammonium bromide (TOAB)-coated gold nanoparticles dispersed in nematic liquid crystals lead to an enhancement of the nonlinear index coefficient, n 2 . A small amount of particles is sufficient to increase n 2 and two-beam coupling gain by more than an order of magnitude while maintaining high optical qualit…
This paper describes an investigation on the use of a new composite construction material composed of plaster, sand, crushed gravel and date palm fibres of waste agriculture peels, having mechanical properties potentially useful in technical domains. Thermal conductivity and some mechanical and physical properties are…
In this work, highly porous nanopaper, i.e., sheets of papers made from non-aggregated nanofibrillated cellulose (NFC), have been surface-grafted with poly(ε-caprolactone) (PCL) by surface-initiated ring-opening polymerization (SI-ROP). The nanopaper has exceptionally high surface area (∼300 m(2)/g). The "grafting fro…
Synthesis of silver nanoplates was studied in the modified polyol method, where the nucleation and seed stage occurred in a poly(ethylene glycol) (PEG)-water mixture solution, and the growth stage happened in the PEG environment. The morphological evolution of nanoplates was characterized using UV, SEM, and TEM. Inter…
The hollow inner spaces of single-wall carbon nanotubes (SWCNTs) can confine various types of molecules. Many remarkable phenomena have been observed inside SWCNTs while encapsulating organic molecules (peapods). However, a mixed electronic structure state of the surrounding SWCNTs has impeded a detailed understanding…
Birefringence in diamond is an anomalous optical property. Its occurrence is the result of strain in the diamond lattice, modifying its natural isotropic properties. However, an understanding of the resultant patterns can give us insights into the causes of the strain, which in turn can provide us with an idea of the…
With increasing interest in new catalytic materials based on doping of ceria with lower-valence metal cation, in this paper, a series of Ce 1– x Zn x O 2-δ (Ce–Zn x ) solid solution catalysts were prepared by a surfactant-free coprecipitation method. The catalytic activity of ceria nanostructures was enhanced by incre…
Widespread adoption of superconducting technologies awaits the discovery of new materials with enhanced properties, especially higher superconducting transition temperatures T(c). The unexpected discovery of high T(c) superconductivity in cuprates suggests that the highest T(c)s occur when pressure or doping transform…
Intense near-infrared (NIR) emission around 1534 nm has been obtained from ZnO-SiO 2:Er 3+ composites upon broadband ultraviolet light excitation. Remarkably, enhancement of the NIR emission as much as 20 times was achieved by optimal codoping with Li + ions. To elucidate the relevant mechanisms, comprehensive spectro…
We present a systematic investigation and analysis of the structure and stability of reverse micelle systems with the addition of NH(4)OH, ZrOCl(2), and Al(NO(3))(3) salts. We demonstrate that the reverse micelle size decreases with increasing salt additions until one reaches a critical concentration, which characteri…
The purpose of this work was to obtain precipitated calcium carbonate (PCC) particles in polymorphic form of vaterite via gas–liquid route in controlled pH conditions. The effect of CO 2 concentration (12.5–100%), feed gas (CO 2 –air) flow rate, pH, and conductivity of solution upon the PCC particles properties was st…
Herein, we report that octahedral and spherical Cu2O samples with hollow structures are synthesized in high yield by reducing Cu(EDA)22+ complex with hydrazine. A series of experiments are carried out to investigate the factors which impact on the morphology of the Cu2O samples. It is observed that ethylenediamine (ED…
SUMMARY A uniform source‐and‐sink scheme was developed by Cao and Li [J. Chem. Phys. 133 (2010), 024106] to calculate the thermal conductivity of solid argon. Now, we aim to apply this scheme to the calculation of the self‐diffusion coefficient. We divide the particles into equal halves, and label them with A or B. By…
Fiber cross section shapes, which have a direct influence on the physical properties of textile surfaces, are becoming more and more complex recently. There are also many important properties of the carpets such as luster, resilience, abrasion resistance which are impacted by the shape of the fiber cross sections. In…
Although iron-based superconductors are multiorbital systems with complicated band structures, we demonstrate that the low-energy physics which is responsible for their high-T c superconductivity is essentially governed by an effective two-orbital Hamiltonian near half filling. This underlying electronic structure is…
Light-responsive drug delivery systems are particularly appealing that are capable of releasing active molecules at the appropriate site and rate. We synthesized a series of photodegradable polymers that can form nanoparticles for drug encapsulation. These particles in aqueous solutions are stable in buffers with diff…
The precipitation of carbonate minerals--mineral trapping--is considered one of the safest sequestration mechanisms ensuring long-term geologic storage of CO(2). However, little is known about the thermodynamic factors controlling the extent of heterogeneous nucleation at mineral surfaces exposed to the fluids in poro…
Recently developed model allows for simulations of electric field influence on the surface states. The results of slab simulations show considerable change of the energy of quantum states in the electric field, i.e. Stark Effect associated with the surface (SSSE - Surface States Stark Effect). Detailed studies of the…
