ZnS nanoparticle (NP) gel networks were used as cation exchange materials for the removal of Pb(2+) and Hg(2+) from aqueous solutions. First, the suitability of the gel as a remediation material was studied by analyzing the mechanism of the cation exchange reaction. ZnS NP gels can exchange with other divalent cations (Pb(2+), Hg(2+)) under mild reaction(More)
Silicon is a convenient and inexpensive platform for radiation detection, but has low stopping power for x-rays and gamma-rays with high energy (e.g., 100 keV, as used in computed tomography and digital radiography, or 1 MeV, as desired for detection of nuclear materials). We have effectively increased the stopping power of silicon detectors by producing a(More)
