Bandgap engineering of TiO2 nanoparticles through MeV Cu ions irradiation

Synthesis of Visible-Light-Responsive Cu and N-Codoped AC/TiO2 Photocatalyst Through Microwave Irradiation

N-Cu-activated carbon (AC)/TiO2 nanoparticles were prepared by the sol-gel technique through microwave irradiation to modify the visible-light response of TiO2. Their structure, surface chemical composition, and optical absorption properties were characterized. The results showed that the codoped particles had a higher surface area and smaller particle size than pure AC/TiO2 and monodoped AC/Ti...

Architectural Growth of Cu Nanoparticles Through Electrodeposition

Cu particles with different architectures such as pyramid, cube, and multipod have been successfully fabricated on the surface of Au films, which is the polycrystalline Au substrate with (111) domains, using the electrodeposition technique in the presence of the surface-capping reagents of dodecylbenzene sulfonic acid and poly(vinylpyrrolidone). Further, the growth evolution of pyramidal Cu nan...

STRAIN/DAMAGE IN CRYSTALLINE MATERIALS BOMBARDED BY MeV IONS: RECRYSTALLIZATION OF GaAs BY HIGH-DOSE IRRADIATION

MeV ion irradiation effects on semiconductor crystals, GaAs(lOO) and Si (111) and on an insulating crystal CaF 2 (111) have been studied by the x-ray rocking curve technique using a double crystal x-ray diffractometer. The results on GaAs are particularly interesting. The strain developed by ion irradiation in the surface layers of GaAs <1go> ~aturates to a certain level after a high dose irrad...

Bandgap engineering through nanocrystalline magnetic alloy grafting on graphene

Removal of Pb(II) and Cu(II) Ions from ‎Aqueous Solutions by Cadmium Sulfide ‎Nanoparticles

   In this study, cadmium sulfide nanoparticles (CdS NPs) were prepared, characterized and used as a new adsorbent for simultaneous removal of Pb(II) and Cu(II) ions from aqueous solutions. Using a batch adsorption method, the effects of solution pH, contact time, adsorbent dose, and temperature were studied and optimized. Removal efficiencies, higher than 98% were obtained for both the met...
