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

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

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...

Polymer architecture allows control of thermoreversible gelation in branched copolymer-stabilised emulsions.

The synthesis, characterization, self-assembly, and gel formation of poly(γ-benzyl-l-glutamate) (PBLG) in a molecular weight range from ca. 7,000-100,000 g/mol and with narrow molecular weight distribution are described. The PBLG is synthesized by the nickel-mediated ring-opening polymerization and is characterized by size-exclusion chromatography coupled with multiple-angle laser light scatter...

The use of poloxamers (PL) have been one of the most widely strategies used for drug delivery systems. The copolymer Poloxamer 407 is a non-ionic surfactant consisting of polioxyethylene (POE) and polioxypropylene (POP) that has many pharmaceutical applications due to its thermoreversible properties. PL are biocompatible and for this reason, are very attractive as carrier systems for administra...

A gel consists of one or more gelling agents and a fluid (organic solvent, water, supercritical liquid) which behaves as a viscoelastic material (soft matter) due to the immobilization of solvent molecules in a three-dimensional network. This network results from the self-assembly of the gelling agent into fibres via non-covalent interactions such as hydrogen bonding, π–π stacking, van der Waal...

Complexation in symmetric solutions of oppositely charged polyelectrolytes is studied theoretically. We include polyion crosslinking due to formation of thermoreversible ionic pairs. The electrostatic free energy is calculated within the Random Phase Approximation taking into account the structure of thermoreversible polyion clusters. The degree of ion association is obtained self-consistently ...

A stimuli-responsive BAB triblock copolymer of PNIPAm- b -PVP- -PNIPAm, which displayed a thermoreversible sol–gel transition, was readily synthesized via redox-initiated aqueous RAFT mediated polymerization, under mild conditions.

Anisotropic particles are used widely to control the thermodynamic and rheological properties of pharmaceuticals, cosmetics, food products, composite materials, and cements. In particular, rod-like particle suspensions exhibit unique equilibrium and non-equilibrium states at low particle loadings due to large excluded volumes and orientation-dependent attractions. However, the coupled effects o...
