Silicon dioxide, commonly known as silica, is one of the most studied materials for the preparation of inorganic membranes. Although silica has several crystalline polymorphs, amorphous silica has been widely studied for the preparation of both mesoporous and microporous membranes. Amorphous silica can be easily synthesized through sol-gel...

Most of the conventional treatments of waste-activated sludge (WAS) are devoted to their minimization and destruction. On the other hand, the biomass contained in WAS can be utilized as a valuable source of renewable carbon. In this study, the influence of different pretreatments (ultra-sonication, chemical, thermal, and combined pretreatments)...

Biosorption of lead and nickel onto almond shells from aqueous solution at various temperatures have been investigated kinetically and thermodynamically. The biomass was characterized by SEM and EDX analysis which additionally authenticated the sorption phenomenon. Thermodynamic parameters clearly demonstrated that all the biomass-metal...

Polyvinylidene fluoride (PVDF) was used for membrane preparation using the nonsolvent induced phase separation (NIPS). In this paper, the effect of the polymer concentration in the dope solution and the nonsolvent bath composition is widely investigated. In particular, the effect of increasing concentrations of ethanol in the coagulation bath...

Membrane distillation is a growing technology that can address the growing problem of water shortage. The implementation of renewable energy and a reduction in the environmental impact of membrane production could improve the sustainability of this process. With this perspective, porous hydrophobic polyvinylidene fluoride (PVDF) membranes were...

Gas Diffusion Layers (GDLs) must have good electrical conductivity and a great hydrophobicity to prevent the pore flooding. These properties can be enhanced by adding a Micro Porous Layer (MPL) based on carbon composites. In this work several MPLs were prepared using carbon-based fillers, such as exfoliated graphite, carbon black and nanotubes,...
