This disclosure demonstrates a new method to produce three dimensional multiphasic structures, including bijels, via vapor-induced phase separation (VIPS). In VIPS, the evaporation of the co-solvent from a ternary mixture of oil, water and ethanol, induces phase separation. Particles present in the mixture attach to the interface and arrest the phase separation between water and oil. VIPS enables, inter alia, the fabrication of films and coatings via spreading or spraying particle-laden suspension onto a surface without the need for an outer aqueous phase.

This disclosure relates to methods of super-cooling of aqueous samples with or without biological samples. The methods involve, e.g., providing a container comprising the aqueous sample; applying an immiscible liquid phase of sufficient thickness to separate the aqueous sample from air; and cooling the aqueous sample to a temperature that is below 0 C.

Some variations provide an emulsion-colloid system for forming a colloidal barrier material disposed on a substrate, the system comprising a hydrophilic first liquid, an acid, a gelling agent, a hydrophobic second liquid, a plasticizer, and optionally additives, wherein the emulsion-colloid system is characterized by (1) a first instance that is a flowable emulsion above 60 C. and less than the boiling point of the first liquid, and (2) a second instance that is a colloid below 40 C. The emulsion-colloid system is capable of reversible transition, mediated by temperature, between the first instance and the second instance. The disclosed colloidal barrier material provides the functionality of plastic alternatives while removing disadvantages. The disclosed colloidal barrier material reduces labor-intensive application of the barrier, such as the case for covering grain piles with plastic tarps. The disclosed colloidal barrier material also eliminates the need for removal when barrier protection is no longer required.

This disclosure provides a hyaluronic acid (HA) bead, a dermal filler having hyaluronic acid (HA) and a process for preparing the HA beads. The process includes combining an HA compound with sodium hydroxide, forming an HA solution, and injecting the HA solution into an oil solution, and forming an emulsion with HA beads. A cross-linking reagent is added and the mixture is stirred for 24 hours in room temperature, thereby forming cross-linked HA beads. The HA beads are cross-linked and adapted to dissolve in vivo upon contact with hyaluronidase.
