Simultaneous exfoliation and colloidal formation of few-layer semiconducting MoS2 sheets in water

A simple method allowing for simultaneous liquid-phase exfoliation of MoS2 crystals into few-layer sheets and colloidal formation of the exfoliated sheets is reported.

Antiscaling efficacy of CaCO3and CaSO4on polyethylene glycol (PEG)-modified reverse osmosis membranes in the presence of humic acid: interplay of membrane surface properties and water chemistry

A specific polyethylene glycol (PEG)–humic acid–SO42−interaction results in promoted CaSO4colloidal formation on PEG reverse osmosis membrane surfaces.

Self-expansion, self-exfoliation and self-dispersion: insights into colloidal formation of atomically thin two-dimensional MoO2.5(OH)0.5

Schematic of the formation mechanism of highly self-dispersible colloidal solutions of monolayered MoO2.5(OH)0.5 nanosheets by self-expansion and self-exfoliation process.

Poly(hydroxyalkanoates)-Based Polymeric Nanoparticles for Drug Delivery

Poly (hydroxyalkanoates) (PHAs) have recently attracted a great deal of academic and industrial interest for their biodegradability and biocompatibility making them suitable for environmental and biomedical applications. Poly(3-hydroxybutyrate-) (PHB-) and Poly(DL-lactide-co-glycolide) (PLGA-) based nanoparticles were prepared using the dialysis method as yet unreported for the preparation of nanoparticles based on PHB. Processing conditions were varied in order to evaluate their influence on morphology, drug encapsulation, and size of nanoparticles. The relevant results obtained give a theoretical understanding of the phenomenon occurring during colloidal formation. The adopted procedure allows for a relatively small diameter and homogeneity in size distribution of the PHB nanoparticles to be obtained compared to other methods like the one based on solvent evaporation which leads to particles on microscale. The biocompatibility of PHB and relative nanoparticles was investigated and both exhibited very good cytocompatibility.
