From colloidal dispersions to aerogels: How to master nanoparticle gelation
Publication date: Available online 20 December 2019Source: Nano TodayAuthor(s): Fabian Matter, Ana Laura Luna, Markus NiederbergerAbstractNanoparticle-based aerogels are one of the few examples of 3-dimensional nanoparticle assemblies that can achieve macroscopic sizes while fully retaining the size-specific properties of the initial nanobuilding blocks. A typical synthesis involves three main steps: i) Preparation of a stable dispersion containing all the building blocks with the desired composition, size, shape and crystallinity, ii) controlled destabilization of the dispersion into a gel, and iii) drying of the gels under preservation of the 3-dimensional nanoparticle architecture. In this review, we focus on the first two steps. We discuss the stability of colloidal dispersions, offering an overview of the different interparticle forces and how they can experimentally be modulated. In the next section, we discuss the gelation process in its entirety, including gelation mechanisms, and, most importantly, how it can rationally be controlled under consideration of the interparticle forces in the dispersion. Finally, the review concludes with an overview of the synthesis pathways to nanoparticle-based aerogels, divided into the gelation of sterically and charge-stabilized particles.Graphical abstract

Conclusions: The food safety conditions and the quality of ice cubes at manufacturing premises in Binh Phuoc Province were not acceptable. Hygiene deficiencies in ice producing and handling processes, inadequate knowledge of staff, inadequate food safety management practices, and hygiene conditions of the premises were important factors in producing contaminated ice products. We recommend more staff training and crediting the staff when performing adequate practices, paying attention to broken floors or difficulty in cleaning, structural deficiency, and ensuring regular monitoring of premises. This study adds a special int...
