Practical Materials for Heavy Metal Ion Chelation: Polyethylenimines tailored onto The Surface of Porous Silica
INTRODUCTION As a result of heavy metal ion release from industrial wastewater, water pollution has become a serious problem. Waste streams contain solutions of metal ions, such as copper, nickel, cobalt and lead. Many reviews have discussed the removal of metal ions from aqueous solutions using approaches based upon adsorption, precipitation, solvent extraction and polymeric membranes. Recentl...
متن کاملTailored porous silicon microparticles: fabrication and properties.
The use of mesoporous silicon particles for drug delivery has been widely explored thanks to their biodegradability and biocompatibility. The ability to tailor the physicochemical properties of porous silicon at the micro- and nanoscale confers versatility to this material. A method for the fabrication of highly reproducible, monodisperse, mesoporous silicon particles with controlled physical c...
متن کاملCharacterize Porous Materials
■ Abstract Beam-based positron annihilation spectroscopy (PAS) is a powerful porosimetry technique with broad applicability in the characterization of nanoporous thin films, especially insulators. Pore sizes and distributions in the 0.3–30 nm range are nondestructively determined with only the implantation of low-energy positrons from a table-top beam. Depth-profiling with PAS has proven to be ...

متن کاملPorous Thermoelectric Materials
Thermoelectric materials are sometimes prepared using a sintering process in which the achievement of a high density is often one of the objectives. However, it has recently been shown that the introduction of a highly porous material is desirable in synthetic transverse thermoelements. Porosity may also be an advantage in conventional longitudinal thermoelectric modules in which a high thermal...
