Droplet formation in the presence of nanoparticles was studied in a T-shaped microfluidic device numerically. Nanoparticles in continuous phase did not influence droplet formation dynamics obviously. Contrarily, the presence of nanoparticles in dispersed phase will influence evidently droplet formation dynamics, likely reasons are the accumulation of nanoparticles at the liquid-liquid interface...

Janus nanoparticles were prepared by interfacial ligand-exchange reactions of hexanethiolate-protected gold (AuC6) nanoparticles with 3-mercapto-1,2-propanediol (MPD) at the air|water interface. As nanoscale analogues to conventional amphiphilic molecules, the resulting Janus nanoparticles were found to form oil-in-water micelle-like or water-in-oil reverse micelle-like superparticulate structu...

In the present study, synthesis, characterization, and the antibacterial activity of silver nanoparticles from native isolate of Corynebacterium glutamicum has been reported. Silver nanoparticles were synthesized by challenging the dried biomass of C. glutamicum with aqueous diamine silver ([Ag (NH3)2]+) containing 1 mM AgNO3. Synthesized silver nanoparticles (AgNPs) were characterized by ultra...

Aqueous extract of shade dried leaves of Euphorbia hirta (L) was used for the synthesis of silver (Ag) nanoparticles. UV-visible spectroscopy studies were carried out to assess the formation Ag nanoparticles. Scanning Electron Microscopic (SEM) was used to characterize the Ag nanoparticles. SEM image divulges that silver nanoparticles are quite polydispersed, the size ranging from 40 nm to 50 n...

Supplementary Figure 1. Fullerence has poor solubility in water while the C60S and LC60S nanoparticles can be stably dispersed in water. (a) A typical photograph of fullerence (C60), C60S nanoparticles, and LC60S nanoparticles in deionized water (2 mg ml-1). The C60S and LC60S nanoparticles can be well dispersed in deionized water while fullerene forms aggregates and sinks down at the bottom of...
