Aqueous multiphase systems (AMPS) were formed by mixtures of three or more incompatible water-soluble macromolecules. Droplets different phases in the water-in-water emulsions found to associate and their morphology was studied using confocal laser scanning microscopy. By analyzing angles between associated it possible determine relative interfacial tensions with respect each other. In this man...

The adsorption of water and substrate on immobilized Candida antarctica lipase B was studied by performing adsorption isotherm measurements and using inverse gas chromatography (IGC). Water adsorption isotherm of the immobilized enzyme showed singular profile absorption incompatible with the Brunauer-Emmet-Teller model, probably due to the hydrophobic nature of the support, leading to very low ...

This article suggests that in the origins of modern state, there is a paradox: the state concentrates the use of violence and, in this way, it is the main source of violence; but at the same time, attempts to delete it. To solve this paradox is the main challenge of the democratic state. If modern state provides security without rights, it would lose legitimacy, its moral advantage. At internat...

A wide range of biorelevant applications, particularly in pharmaceutical formulations and the food and cosmetic industries, require the stabilization of two water-soluble blended components which would otherwise form incompatible biphasic mixtures. Such water-in-water emulsions can be achieved using Pickering stabilization, where two-dimensional (2D) nanomaterials are particularly effective due...
