Prospects of 2D graphdiynes and their applications in desalination and wastewater remediation.

Water is an indispensable part of human life that affects health and food intake. Water pollution caused by rapid industrialization, agriculture, and other human activities affects humanity. Therefore, researchers are prudent and cautious regarding the use of novel materials and technologies for wastewater remediation.

Role of reactant concentration and identity of added cation in controlling emission from post-synthetically modified terbium incorporated zinc sulfide nanoparticles: an avenue for the detection of lead(ii) cations.

This work reports the photophysical properties of 1-thioglycerol capped hydrophilic terbium cation incorporated (doped) zinc sulfide [Zn(Tb)S] nanoparticles, which have been post-synthetically modified using Pb [Zn(Tb)S/Pb] under ambient conditions with [Zn(Tb)S] : [Pb] = 1 : 10-1 : 10, essentially providing a scenario with low to heavy co-doping and ultimately the possibility of forming a material of different chemical identity. The effects of selected concentrations of [Zn(Tb)S] : [M ] = 1 : 1 and 1 : 10 have also been evaluated for the post-synthetic addition of Hg, Cd, Ca, Mg, Na and K. The broad zinc sulfide nanoparticle and sharp Tb emission have different dependence on the relative reactant concentration, with cation identity playing a significant role.
