In the present work, the effects of swift silver ion irradiation in crystalline gallium phosphide samples with various fluences ranging between 1 × 1011 and 2 × 1013 ions cm−2 have been described. Atomic force microscopy images of the samples irradiated with different fluences showed the exist...

In this work, we have investigated the structural and magnetic properties of GaP-based diluted magnetic semiconductors (DMSs). Based on first-principle density functional theory (DFT) calculations and using a full potential linearized augmented plane wave (FP-LAPW) method in generalized gradient...

In this work, we study the structural phase transitions of gallium phosphide (GaP), witha combination of molecular dynamics simulations (MD) and ab initio calculations based on density functional theory (DFT) with vibrational corrections within the harmonic approximation, for pressures up to 50 ...

Polyhedra have been formed by dissolution of single-crystal spheres of gadolinium gallium garnet in a PbO/B2O3 flux at about 1000°C. The curved segments between the edges of the dissolution form show {210} and {331} orientations. Their formation is discussed in terms of a model which takes into...

Polycrystalline gadolinium gallium mixed oxides were prepared by coprecipitation and annealing at various temperatures below 1000 °C. The oxide materials appear to be X-ray amorphous after a heat treatment at 500 °C for 30 h, but after 30 h at 800 and 900 °C a major, unreported, hexagonal pha...

The formation of oxide nanoclusters in oxide dispersion strengthened steels is controlled by the diffusion of yttrium. Yttrium atoms and other oversized solutes show a high binding energy to vacancies and a considerable relaxation from their lattice site towards a neighboring vacancy. In the cas...

An interatomic potential for iron-yttrium is presented that allows to investigate the diffusion of yttrium in iron. The potential provides a complete description of the elastic and thermal properties of yttrium. The iron-yttrium interaction is fitted with focus on yttrium point defects in an iro...

Tritium permeation through structural materials is a critical issue in fusion reactors from the viewpoints of sufficient fuel balance and radiological hazard. Ceramic coatings have been investigated as tritium permeation barrier for several decades; however, irradiation effects of the coatings o...

Ceramic coatings have been investigated as tritium permeation barrier for several decades; however, there is little knowledge about irradiation effects on the coatings.

Preparation of a novel yttrium-iron garnet of the chemical formula Y3-xFe5+xO12, where 0.1≤x≤1.5, is reported. Epitaxial films of this garnet were grown by the liquid phase epitaxy technique from the PbO–B2O3 solution containing weakly dissociated both yttrium-iron garnet Y3Fe5O12 and yttrium...

In this work, high quality yttrium-iron-garnet (YIG) thin films were fabricated on a Ga3Gd5O12 substrate by pulsed laser deposition (PLD). The material composition, iron ion valences and magnetic properties of the YIG films were systematically investigated as a function of annealing temperature....

Arsenic contamination is one of serious environmental problems in the world. In this study, an innovative yttrium-doped iron oxide magnetic adsorbent was synthesized through a simple precipitation method for better arsenic decontamination and ease in separation after the application. The adsorbe...

The mechanism that iron sulfide-coated nanoscale zero valent iron (S-nZVI) has better reduction activity towards organic pollutants than nanoscale zero-valent iron (nZVI) has long been debated. In this work, a systematic study was investigated to compare differences of main influences, BDE-209 d...

A comparative study of the electrochemical reduction of iron(III) and copper(II) ions on selected sulfide minerals in concentrated chloride solutions has been carried out as part of a broader study of the kinetics of the leaching of chalcopyrite, covellite, enargite and pyrite under chloride hea...

This study examined the reaction mechanism of arsenite, As(III), and antimonite, Sb(III), with iron sulfide and compared their pH-dependent reaction behaviors under strictly anoxic environments. The comparison of Sb(III) with As(III), based on their chemical similarity, may provide useful insigh...

Iron oxide thin films have been obtained significant interest as a material that put forwards applications in photovoltaics, gas sensors, biosensors, optoelectronic and especially in spintronics. Iron oxide is one of the considerable interest due to its chemical and thermal stability. Metallic i...

Massive emissions of smelting waste slag (SWS) cause serious harm to environment because of including toxic metal such as zinc and lead.
