A novel separation technique for aqueous nanoparticles based on a phase transfer approach
Synthetic preparations of nanoparticles often create a mixture of sized particles; however, the properties and suitability for a specific application is often linked directly to their physical dimensions. In this hot paper Yiping Cui and colleagues report a phase transfer approach for separating different sized particles. Using an anti-charged surfactant in oil phase allowed the team to extract small nanoparticles into the oil phase while leaving larger nanoparticles behind in the aqueous phase.

The selective intercalation of organic carboxylates and sulfonates into hydroxy double salts
Hydroxy double salts can selectively store and deliver a range of functional anions via ion exchange; however, unlike the related layered double hydroxide family they have received relatively little attention. This hot paper Gareth R. Williams and co-workers report the first systematic investigation of the selectivity of organic guest intercalation into hydroxy double salts.
