Aerogels have numerous applications due to their high surface area and low densities. However, creating aerogels from a large variety of materials has remained an outstanding challenge. Here, we report a new methodology to enable aerogel production with a wide range of materials. The method is based on the assembly of anisotropic nano-objects (one-dimensional (1D) nanotubes, nanowires, or two-d...

BACKGROUND Aerogels are a versatile group of nanostructured/nanoporous materials with physical and chemical properties that can be adjusted to suit the application of interest. In terms of biomedical applications, aerogels are particularly suitable for implants such as membranes, tissue growth scaffolds, and nerve regeneration and guidance inserts. The mesoporous nature of aerogels can also be ...

An integrated extraction–separation process: extraction and selective separation of chlorophylls betalains using thermoreversible aqueous biphasic systems.

Simulations of a flexible coarse-grained model are used to study silica aerogels. This model, introduced in a previous study (J. Phys. Chem. C 2007, 111, 15792), consists of spherical particles which interact through weak nonbonded forces and strong interparticle bonds that may form and break during the simulations. Small-deformation simulations are used to determine the elastic moduli of a wid...

A new thermoreversible hydrogel of riboflavin and melamine supramolecular complex (> or =0.02%, w/v) shows enhanced photoluminescence properties through H-bonding.

The gelation of a low value-added industrial waste, phenolic oil (PO), was successfully carried out for the first time in presence an acid catalyst and paraformaldehyde (PF), which is by-product formaldehyde industry. Therefore, use PO PF can be considered win-win situation as attempt to valorise these ‘wastes’ integrate them into circular economy. A broad range formulations has been explored, ...

AlF3-based aerogels, a new class of inorganic aerogels, are prepared in a novel direct process that combines fluoride sol-gel synthesis with high temperature supercritical drying. The bulk structure of the solid products depends decisively on the applied solvent(s); very voluminous bulk aerogels are obtained only with MeOH that is used either alone or in combination with some other polar solven...

Soft-ionic materials with biocompatibility and 3D printability are needed to develop next-generation devices interface between electronic biological signals. Herein, thermoreversible biocompatible ionic liquid gels or iongels, which can be processed by direct ink writing reported. The iongels designed taking advantage of polyvinyl alcohol/phenol interactions gelify cholinium carboxylate liquids...

High porosity solids, such as plastic foams and aerogels, are thermally insulating. Their insulation performance strongly depends on their pore structure, which dictates the heat transfer process in the material. Understanding such a relationship is essential to realizing highly efficient thermal insulators. Herein, we compare the heat transfer properties of foams and aerogels that have very hi...
