Freestanding Ultrathin Nanoparticle Membranes Assembled at Transient LiquidLiquid Interfaces
(please note that in this context, we defi ne as membrane any freestanding thin layer, regardless of selective mass-transport properties). These approaches rely on the possibility of NPs to adsorb and pack into a dense network at an interface. This can occur if the free energy of the nanoparticles bound at the interface is lower than that of the NPs in either of the two phases. [ 38–40 ] The su...
متن کاملTowards Controlled Liquid Atomization
The present study discuss controlling mechanisms of air-blast atomization and the prospect of external triggering for enhancing atomization quality of a planar liquid sheet. The investigation builds on previous experimental evidence provided by flow visualization of 2-D liquid sheets formed between two co-flowing air streams at variable velocities, and is particularly aimed to improve our under...
متن کاملSolid phase microextraction.
Solid Phase Microextraction (SPME) uses a small volume of sorbent dispersed typically on the surface of small fibres, to isolate and concentrate analytes from sample matrix. After contact with sample, analytes are absorbed or adsorbed by the fibre phase (depending on the nature of the coating) until an equilibrium is reached in the system. The amount of an analyte extracted by the coating at eq...
متن کاملHeadspace Liquid Microextraction
2 Headspace sampling for gas chromatographic (GC) analysis has many advantages, the most important of which is the elimination of many interferences from the sample matrix. In addition to the standard methods for headspace sampling, the technique of solid-phase microextraction (SPME) has found wide acceptance because it is simple and inexpensive. More recently, single-drop microextraction (SDME...
متن کاملLiquid-phase microextraction
The development of faster, simpler, inexpensive and more environmentally-friendly sample-preparation techniques is an important issue in chemical analysis. Recent research trends involve miniaturization of the traditional liquid-liquid-extraction principle by greatly reducing the acceptor-to-donor ratio. The current trend is towards simplification and miniaturization of sample preparation and d...
