A novel continuous flow synthesis method was performed to achieve ultra-small Pt NPs (2.3 to 2.5 nm) with narrow size distribution. This method expedites the synthesis of Pt NPs without any harsh reducing agent or capping agent.

Modified Polyol Method

SnO2 powders were prepared using a modified polyol synthesis method and subsequent calcinations. Well-dispersed spherical 2SnO∙(H2O) particles could be synthesized at room temperature through the modified polyol method using tin (II) 2-ethylhexanoate as the precusor, 1,2-propanediol as the solvent, PVP as the capping agent, and sodium borohydride as the reducing agent. The 2SnO∙(H2O) nanoparticles agglomerated to form larger particles during the drying step, and most of these larger nanoparticles coalesced with one another. Finally, these 2SnO∙(H2O) nanoparticles were successfully transformed into the SnO2 phase by calcination for 1 h at 500 °C.

Abstract.All observed optical and infrared properties of Saturn's E-ring can be explained in terms of Mie scattering by a narrow size distribution of ice spheres of 2 - 2.5 micron diameter. The spherical shape of the ring particles and their narrow size distribution imply a molten (possibly volcanic) origin on Enceladus. The E-ring consists of many layers, possibly stratified by electrostatic levitation.
