The thermal degradation of chitin and chitosan have been studied by using simultaneous TG and DSC in nitrogen atmosphere. The model-free iso-conversional method has been employed to evaluate the activation energies as a function of the extent of…

Kinetics of the first order volume-phase transition of submillimeter gels is investigated for various initial and final states of the transition. Characteristic times for swelling and shrinking critically depend on the final state, but are much less…

Remarkable progress has been made recently in the understanding of the kinetics of the phase transition in polymer gels. This rich, scientific problem with substantial technological significance will be reviewed.

We present a theroy of the kinetics of the swelling of a gel. The characteristic time of swelling is proportional to the square of a linear dimension of the gel and is also proportional to the diffusion coefficient of the gel network, which is…

The swelling limit or equilibrium swelling of semicrystalline or cross-linked polymers and of their gels upon immersion in liquids has been investigated extensively. Few studies, however, have dealt with the kinetics of swelling. Theoretical…

Building on social embeddedness theory, we examine how the competencies and resources of one corporate actor in a network are transferred to another actor that uses them to enhance transactions with a third actor-a strategic process we dub 'network…
