In bio-hydrometallurgical operations, several studies found that besides having inhibitory effects chloride may also enhance the bacterial leaching of metal sulfides. This study compares the effect of chloride on bacterial growth, iron oxidation activity and bioleaching performance of Leptospiri...

Silver-zinc oxide nanocomposite (Ag-ZnO nanocomposite) were synthesised with different concentrations of Ag doped to the ZnO for enhance photocatalytic degradation of methylene blue. The structures, morphologies, and optical properties of synthesised nanocomposites were characterized by UV-Visib...

This article presents a new method for the simpler and faster determination of tin in beverages using EDXRF. Absorption coefficients for aqueous calibration samples were calculated and shown to be nearly identical to those of the beverage samples, thus permitting the use of aqueous standard solu...

In this paper, carboxylated ethylenediamine functionalization Fe3O4@SiO2 nanoparticles (Fe3O4@SiO2-EDA-COOH NPs) have been developed in order to remove methylene blue (MB) from aqueous solution. The chemical structure, morphology and magnetic characteristics of the magnetic composite nanoparticl...

Dyeing of solid wood using scCO2 as transport medium does not afford satisfying results as exemplarily demonstrated for disperse blue 134 and different wood species. Surprisingly, the bark of cork oak featuring closed porous architecture could be easily dyed with DB 134 which was hypothesized to...

A novel low-cost adsorbent was produced from clay mineral of vermiculite using chemical modification. The vermiculite was modified with polyamide through in-situ interfacial polymerization. Adsorption performance of the modified adsorbent was investigated for methylene blue removal from aqueous ...

Alkali-clearable disperse dyes display high washing fastness on PET. The alkali-clearability of phthalimidyl azo disperse dyes can be explained by the hydrolysis of imido ring creating a water-soluble phthalate groups under alkaline conditions. Hydrolysis performance of six phthalimide disperse ...

This work reports the synthesis of highly dispersed Mn-Co/RGO via a novel light driven approach having attributes of being green, facile and controllable, for the catalytic degradation of methylene blue (MB) in the presence of H2O2. The prepared catalysts were characterized by TEM, EDS, IR, XRD ...

The solubility of disperse dyes and their mixture in supercritical carbon dioxide is an important property in study and development of supercritical fluid dyeing technology. In this study, solubilities of C.I. Disperse Red 73, C.I. Disperse Blue 183 and their mixture in supercritical CO2 are mea...

Few rocks or minerals display a blue hue; this is especially true for natural glasses. As glasses are already uncommon compared to crystalline rocks due to their instability, the rarity of blue glass makes a fulgurite found in Marquette Michigan worthy of further examination. We study the morpho...

In the present investigation the poorly crystalline hydroxyapatite was rapidly fabricated by the gel auto-ignition route using calcium nitrate tetra-hydrate and di-ammonium hydrogen orthophosphate as a starting materials and urea as a fuel. The produced powders were employed as adsorbents for up...

Temperature dependencies of the densities of dimethylsulfoxide solutions of lanthanum, gadolinium and lutetium trifluoromethanesulfonates have been determined over a wide range of concentrations. The apparent molar volumes and partial molar volumes of the salts at infinite dilution, as well as t...

Lu2SiO5:Ce powders have been synthesized by mechanochemical processing of the constituent oxides and by urea/hexamine-nitrate-based solution-combustion methods with microwave and furnace sintering of each material. Powder x-ray diffraction (PXRD), photoluminescence excitation (PLE) and emission ...

Currently, twenty-eight gallium, thirty-one germanium, thirty-five lutetium, and thirty-six hafnium isotopes have been observed and the discovery of these isotopes is described here. For each isotope a brief synopsis of the first refereed publication, including the production and identification ...

The thermal decomposition of lutetium(III) propionate monohydrate (Lu(C2H5CO2)3·H2O) in argon was studied by means of thermogravimetry, differential thermal analysis, IR-spectroscopy and X-ray diffraction. Dehydration takes place around 90 °C. It is followed by the decomposition of the anhydro...

A simple, low-cost hydrothermal method was developed to synthesize irregular-and rod-shaped lutetium disilicate (Lu2Si2O7) powders with sizes ranging from 71 to 340 nm. The synthesis temperature was 260 °C, which is nearly 1300 °C lower than that required for the solid-state reaction. The resu...

The aim of this study is to compare the photophysicochemical properties of hexaphenoxycyclotriphosphazenyl-substituted metal-free (1), mono-(phthalocyaninato) lutetium(III) (2) [LuIII(AcO)(Pc)] (Pc = phthalocyaninato, AcO = acetate) and bis-(phthalocyaninato) lutetium(III) (3) [LuIIIPc2]. The sy...

The lutetium–hafnium (Lu–Hf) isotope record, typically measured in zircon crystals, provides a major tool for the study of crustal growth and differentiation. Interpretations of Hf isotope datasets use an evolution array defined by source 176Lu/177Hf. However, the very process that drives crus...

Solvent extraction has been the most widely used technique for rare earths separation. In this study, thermodynamics and kinetics of lutetium extraction with HEH (EHP) in hydrochloric acid medium were investigated. The extraction mechanism and the relevant parameters were determined by experimen...

Targeted radionuclide therapy generally relies on the chelation of select short-lived isotopes such as 177Lu and 67Cu. The majority of Lu(III) and Cu(II) chelate structural information is derived from solid state diffraction data. Herein, the complexes Lu(DOTA)−, Cu(NOTA)− were examined in solut...
