Heavy Metal Remediation

Quantum dots (QDs), the fluorescent nanoparticles with multiplexing competency are applicable in broad range of fields. The application of QDs in separation processes is a relatively new approach, still presenting the spectacular advancement and wider future scope. The unique features of QDs endorse their use in wastewater treatment, chromatographic separation and heavy metal remediation. QDs also assist the separation of biomarkers, pathogens and tumor cells for biomedical applications. These tiny particles possess tremendous potential to deal with bigger global issues such as water desalination and early cancer diagnosis. To the best of our knowledge, it is the first most report summarizing the QDs uses for multiple separation processes.

Modern and future nanoelectronic and nanophotonic applications require precise control of the size, shape and density of III-V quantum dots in order to predefine the characteristics of devices based on them. In this paper, we propose a new approach to control the size of nanostructures formed by droplet epitaxy. We reveal that it is possible to reduce the droplet volume independently of the growth temperature and deposition amount by exposing droplets to ultra-low group-V flux. We carry out a thorough study of the effect of arsenic pressure on the droplet characteristics and demonstrate that indium droplets with a large initial size (>100 nm) and a low surface density (<108 cm−2) are able to shrink to dimensions appropriate for quantum dot applications. Small droplets are found to be unstable and difficult to control, while larger droplets are more resistive to arsenic flux and can be reduced to stable, small-sized nanostructures (~30 nm). We demonstrate the growth conditions under which droplets transform into dots, ring and holes and describe a mechanism of this transformation depending on the ultra-low arsenic flux. Thus, we observe phenomena which significantly expand the capabilities of droplet epitaxy.
