Droplet-based microreactor for synthesis of water-soluble Ag₂S quantum dots

, : Droplet-based microreactor for synthesis of water-soluble Ag₂S quantum dots. Nanotechnology 26(27): 275701-275701

A droplet-based microreactor was used for synthesis of water-soluble Ag2S quantum dots (QDs). Monodispersed Ag2S nanoparticles with a surface of carboxylic acid-terminated were synthesized in the droplet microreactor. The x-ray powder diffraction results indicated products were monoclinic Ag2S nanocrystals. Furthermore, different-sized Ag2S QDs that were near-infrared-emitting or visible-emitting were continuously stably synthesized in droplet microreactors at different temperatures. We believe we offer a new method for obtaining different-sized Ag2S nanoparticles.

Newly developed sensors, including the EnviroSCAN capacitance system have the potential to monitor and estimate soil moisture content continuously at various depths. A simple site calibration of the sensors is required to obtain accurate soil wate...

Functional hand reconstruction following treatment of soft tissue sarcomas (STS) is a difficult surgical problem. Because survival rates between amputation and limb salvage do not differ, there is a trend toward reconstruction. Unlike amputation,...
