Abstract:
... Poly-N-isopropyl acryl amide (PNIPAM) is swollen in both pure water and pure methanol but collapses in mixtures of these solvents. In this review, this cononsolvency of PNIPAM in water/methanol mixtures is discussed. Experimental studies of linear PNIPAM chains and macrogels are compared to microgels. Theoretical studies are presented based on molecular dynamics simulation and quantum mechanical c ...

Abstract:
... Over the past two decades, nanocarriers prepared through ionic crosslinking of polyelectrolytes have been explored in a wide range of applications, including drug delivery, medical imaging and food science. The design and use of these materials require control over their size distributions, stability, and payload uptake and release properties. To this end, we focus on recent progress made towards ...

Subject:
crystallization; electrodes; lithium batteries; nanoparticles; photocatalysis
Abstract:
... Mesocrystals are superstructures of nanoparticles with mutual order and can be intermediates in a non-classical particle-mediated crystallization reaction. Mesocrystals have various potential applications as functional materials due to their unique combination of nanoparticle properties and order combined with a microscopic or even macroscopic size. They can also show collective and emergent prope ...

Although stratification in polymeric colloids and films has been known for a long time, its significance has not been recognized until surface-interfacial properties driven by mobility of dispersing agents became one of the key features that impact structure–property relationships. Learning from these studies, the last decade resulted in significant advances that have led to the development of a n ...
