The present review aims to summarize the research efforts undertaken in the last few years in the development and testing of hydrogel-clay nanocomposites proposed as carriers for controlled release of diverse drugs. Their advantages, disadvantages and different compositions of polymers/biopolymers with diverse types of clays, as well as their interactions are discussed. Illustrative examples of studies regarding hydrogel-clay nanocomposites are detailed in order to underline the progressive researches on hydrogel-clay-drug pharmaceutical formulations able to respond to a series of demands for the most diverse applications. Brief descriptions of the different techniques used for the characterization of the obtained complex hybrid materials such as: swelling, TGA, DSC, FTIR, XRD, mechanical, SEM, TEM and biology tests, are also included. Enlightened by the presented data, we can suppose that hydrogel-clay nanocomposites will still be a challenging subject of global assiduous researches. We can dare to dream to an efficient drug delivery platform for the treatment of multiple affection concomitantly, these being undoubtedly like ”a tree of life” bearing different kinds of fruits and leaves proper for human healing.

Platform work is often advocated as offering freedom of work to labour. Contesting this claim, this article undertakes a comparative analysis of the pros and cons of food delivery platform work prior to and during the COVID-19 pandemic, and argues that the freedom of food delivery platform workers is essentially an ‘illusory freedom’. In reality, platform work has only changed mechanisms through which companies can exercise control over labour and evade their employer obligations. As a case, the article examines the illusory freedom of food delivery platform workers associated to Uber Eats in Japan. The collective bargaining efforts of food delivery workers against the excessive control of Uber Eats and the extent of success of these efforts are also examined. The article concludes by discussing the possible factors that have undermined the effectiveness of the collective bargaining efforts of the labour union. JEL Codes: J52; J81
