Optimization of Copper and Zinc ions removal from aqueous solution by modified Nano-bentonite using Response surface methodology

Presence of heavy metal ions in wastewater is an important public concern. Adsorption are commonly used technique to remove various pollutants, including the ions, from contaminated water sources. However, common methods for adsorption are not completely efficient at low ion concentrations and the adsorbent should be improved in order to reaching the acceptable levels of adsorption efficiency. ...

Synthesis of nano-structured sphene and mechanical properties optimization of its scaffold via response surface methodology

Nano-structured sphene (CaTiSiO5) powder was synthesized via mechanical activation and heat treatment method. The synthesized powder was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and simultaneous thermal analysis (STA). The sphene scaffolds were then fabricated via porogen method (using citric acid). Response surface methodology was successfully used to d...

On the PEEK composites reinforced by surface-modified nano-silica

The nano-sized silica fillers reinforced poly(ether ether ketone) (PEEK) composites were fabricated by means of compression molding technique. he nano-sized silica, measuring 30 nm in size, was firstly modified by surface pretreatment with stearic acid. The performances and properties f the resulting PEEK/SiO2 nanocomposites were examined in terms of tensile loading, hardness, dynamic mechanica...
