Cristobalite is a common mineral in volcanic ash produced from dome-forming eruptions. Assessment of the respiratory hazard posed by volcanic ash requires understanding the nature of the cristobalite it contains. Volcanic cristobalite contains coupled substitutions of Al3+ and Na+ for Si4+; similar co-substitutions in synthetic cristobalite are known to modify the crystal structure, affecting t...

Mesoporous anatase TiO2 spheres (MATS) are elaborated via microwave-assisted rapid crystallization of hydrous colloidal (HTCS) self-template. Tuning the hydrothermal and calcination temperatures allow for textural property-controllable synthesis. The optimal MATS demonstrated as a promising cathode material aluminium-ion batteries (AIBs) show superior rate capacity performances. Their large sur...

In regard to the role of Aluminium in the emergence of psychological disorded in patients with chronic kidney diseases,this research project studied the acute,and chronic effects of Alluminium on different stages of memory and learning abilitis,after grouping the rats Alluminium chloride with concentrations of 1mg,5mg,10mg and 20 mg was used per kg of body weight.the Alluminium was given by int...

A micro-addition (0.025 at.%) of slow-diffusing W to an Al-0.26Mn-0.11Mo-0.11Si-0.08Zr-0.02Sc-0.01Er (at.%) alloy accelerates L12-Al3(Zr,Sc) precipitation but retards ?-Al(Mn,Mo)Si precipitation. The increases the peak-microhardness during isothermal aging does not improve coarsening resistance and creep resistance.

The nickel removing by electrocoagulation of Ni(II)-NH3-CO2-SO2-H2O system was studied in a batch reactor 50 L useful volume, with stirring, and two pairs aluminum electrodes. operating parameters were concentration between 255 342 mg L-1, current density 11.0 16.6 mA cm-2, pH 8.34±0.06, mean temperature 58.4±3.9 oC retention time min. maximum removal 99.7 % at specific energy consumption 16.86...

The limiting factor in acid dry land is root poisoning by Al3+. Hamill cultivar (Panicum maximum cv Hamil) a plant that commonly used farmer, where the production of matter not much different from elephant grass. This study aimed to evaluate productivity hamil cultivars on soil. research was conducted greenhouse Research Institute Animal Production Ciawi. completely randomized design with 10 re...

One-pot solvothermal synthesis of a robust tetranuclear sodium hexakis(glycolato)tris(methanolato)aluminate complex Na3[Al4(OCH3)3(OCH2CH2O)6] via a modified yet rigorous base-catalyzed transesterification mechanism is presented here. Single crystal X-ray diffraction (SCXRD) studies indicate that this unique Al complex contains three penta-coordinate Al3+ ions, each bound to two bidentate ethyl...

The effects of polyvalent metal cations on pyrene binding to hydrophobic acid and neutral fractions (HoA and HoN, respectively) of dissolved organic matter (DOM) were elucidated. The DOM was isolated from sewage sludge; pyrene binding was estimated from fluorescence measurements. Isotherms of pyrene binding to both fractions were nonlinear. Pyrene binding was higher for HoN due to the combined ...
