By reaction between synthetic phosphosiderite FePO4·2H2O, urea (NH2)2CO, and acetone (CH3)2CO, we report a novel solvothermal synthesis of polycrystalline NH4FePO4·H2O. The preparation of other two individual phases, NH4Fe2(OH)(PO4)2·2H2O and NH4Fe2(PO4)2, is also described. The obtained prod...

For magnetic control of cells for biomedical applications such as targeting of immune cells to tumors, cells must be magnetizable. For that, cells are incubated with superparamagnetic iron oxide nanoparticles (SPIONs) to take them up and thus become magnetizable. When using adherent cells, non-i...

The magnetic hybrid material, based on the aquapentachloridoferrate (III), [FeCl5(H2O)]2- and on the dicystaminium cation H2Cys, is reported for the first time in this paper exhibiting an interesting thermochromic behaviour. It was prepared as orange single crystals, suitable for single crystal ...

This work examines the mill scale (MS) of hot rolling, a waste product formed in industrial steel processing. MS was evaluated as an iron source in promoting the oxidation of Reactive Red 120 azo dye in location-sourced and factory textile wastewater through a Fenton reaction (FR), as well as re...

Free-volume structure of glassy lithium tetraborate Li2B4O7 is studied as compared with isocompositional crystal using positron annihilation lifetime spectroscopy in mixed positron-trapping and Ps-decaying modes exploring three-term decomposed positron lifetime spectra. The longest-lived lifetim...

It is worth to continuous and systematic investigations related with magnesium tetraborate (MBO) due to its attractive candidate for dosimetric application. The study was done to develop new phosphor with adding strontium (Sr) into MBO which was prepared by the simple high temperature solid stat...

The anodizing of aluminum in an alkaline sodium tetraborate (Na2B4O7) solution was investigated with respect to the nanostructural characterization of anodic porous alumina. Electropolished aluminum specimens were galvanostatically anodized under various conditions in 0.1–0.5 M sodium tetrabora...

The reduction of samarium in air fired samples of barium tetraborate has been identified for the first time by divalent samarium emission spectroscopy. The samarium(II) fluorescence is significantly quenched at ambient temperatures, but is apparent upon cooling of the sample to 77 K. Formation o...

Selected platinum complexes catalyze the stereoselective addition of acetic acid to bicyclo[2.2.1]hepta-2,5-diene to form exo-5-acetoxybicyclo[2.2.1]hept-2-ene. Experiments with acetic acid-O-d1 have shown that the reaction involves a highly stereoselective skeletal rearrangement of the substrat...

The roles of cesium (Cs) and oxides in the processing of gallium aluminum arsenide (GaAlAs) photocathodes have been investigated. The Cs/O activation, Cs/O reactivation and degradation experiments are performed on GaAlAs photocathode. The activated photocurrent, degraded photocurrent and quantum...

Although neutrons do not couple directly to the superconducting order parameter, they have nevertheless played an important role in advancing our understanding of the pairing mechanism and the symmetry of the superconducting energy gap in the iron arsenide compounds. Measurements of the spin and...

Heavy Ion Backscattering Spectroscopy (HIBS) using 12 MeV 12C ions was used to examine GaAs (1 0 0) and GaAs (1 1 1) layers grown by Molecular Beam Epitaxy (MBE) on BaF2 (1 0 0) and BaF2 (1 1 1) layers, respectively. HIBS was the only available technique able to verify the GaAs ratio in these sa...

In this paper, thermal-assisted field emission properties of barium oxide (BaO) nanowire synthesized by a chemical bath deposition method were investigated. The morphology and composition of BaO nanowire were characterized by field emission scanning electron microscopy (FESEM), high resolution t...

The interaction between the components of the ternary Y–Ni–P system has been investigated by means of electron probe microanalysis, X-ray phase and structure analyses, and the isothermal section of the phase diagram at 1070 K has been constructed for the first time. Existence of the earlier re...

The testicular toxicities of gallium arsenide (GaAs), indium arsenide (InAs) and arsenic trioxide (As 2O 3) were examined by repetitive intratracheal instillation using hamsters. GaAs (7.7 mg/kg) and As 2O 3 (1.3 mg/kg) were instilled twice a week a total of 16 times and InAs (7.7 mg/kg) was ins...

This work is motivated by the recent developments in online minerals analysis in the mining and minerals processing industry via nuclear quadrupole resonance (NQR). Here we describe a nuclear magnetic resonance (NMR) and NQR study of the minerals tennantite (Cu12As4S13) and tetrahedrite (Cu12 Sb...

We have performed first-principles calculations on orthorhombic antimony sulphide (Sb2S3) nanowire using full-potential linearized augmented plane wave (FP-LAPW) method based on the density-functional theory (DFT) as implemented in WIEN2k package to investigate the electronic and optical propert...

Using first-principles calculations, we investigate the geometric structures, stabilities, electronic structures, and magnetic properties of three kinds of AsP monolayers: blue-phosphorene-like AsP (blue AsP), black-phosphorene-like AsP (black AsP) and puckered AsP. Stability analysis implies a ...

Niobium palladium arsenide, Nb5Pd4As4, is the second phase found in the Nb–Pd–As system. It was synthesized by direct reaction of the elements and its crystal structure was determined from X-ray diffraction data obtained with synchrotron radiation on a 5×5×5 μm3 single crystal at 150 K. Nb5...
