“…Some grains exhibit a roughly cubic shape associated with the cubic phase of PbS. 25 On ZnS, the grains are smaller in the initial stages (10-20 nm aer 40 cycles, Fig. 3c) and more uniform than on TiO 2 .…”

“…1d, the PbS obtained at 70 °C only had a broad peak between 25° and 30°, suggesting its amorphous nature. For 95 °C and 120 °C treatments, sharp peaks were observed at 25.9°, 30.0°, 43.0°, 51.0° and 53.4°, which can be indexed to crystal planes of (111), (200), (220), (311) and 222, respectively, according to the International Centre for Diffraction Data (ICDD) Card No.65-0132 (Chongad et al 2016). Apart from PbS, no other crystalline phases were observed, implying higher purity of the PbS generated at 95 °C and 120 °C.…”

Glass waste dumps from crystal glass production is an health issue due to the occurrence of antimony, arsenic, cadmium and lead in crystal glass. Recovery of those elements could both decrease pollution and recycle metals in the circular economy. Pyrometallurgy is a potential recovery method, yet limited by high energy consumption. Here we tested a lower-energy alternative in which glass is mechanically activated in a ball mill and leached with nitric acid. Results show that mechanical activation destabilised the glass structure and resulted in 78% lead extraction during leaching at 95 °C. Temperature had the most significant effect on extraction, whereas acid concentration, from 0.5 to 3 M, and leaching time, from 0.5 to 12 h, had insignificant effects. In each experiment, 75% of the final extracted amount was achieved within 30 min. The study demonstrates potential for lead extraction from glass waste at lower acid concentration, shorter leaching time and lower temperature, of 95 °C, than traditional pyrometallurgical extraction, typically operating at 1100 °C.

Bilayer nanocomposite films composed of two different metal atoms possess unique physical and chemical properties due to their nanosize and tailored structure. In the present study a magnetic (cobalt) and a nonmagnetic (silver) atom has been selected for forming the bilayer. In the earlier reports Cobalt (Co) has been used as underlayer while the silver (Ag) has been used as overlayer. In the present study, the bilayer has been designed with Ag as underlayer and Co as overlayer. Ion beam sputtering (IBS) was used to deposit 4nm layer of Ag on pre-cleaned float glass substrate. An overlayer of 10nm of Co was also deposited using IBS over the Ag layer. The bilayer film was characterized using GIXRD and MOKE. The GIXRD pattern showed peaks belonging to cobalt which indicate formation of FCC phase. Interestingly Ag peaks are also seen clearly, although Ag is the underlayer. The particle sizes of Ag and Co as evaluated by Scherrer formula are found to be 5.5nm and 4nm respectively. The magnetic property was studied by MOKE which showed presence of well-defined hysteresis loop with coercivity of about 116 Oe. The results are described in light of interaction of the two metals.
