Assessing polymer-surface adhesion with a polymer collection

Polymer modification plays an important role in the construction of devices, but the lack of fundamental understanding on polymer-surface adhesion limits the development of miniaturized devices. In this work, a thermoplastic polymer collection was established using the combinatorial laser-induced forward transfer technique as a research platform, to assess the adhesion of polymers to substrates of different wettability. Furthermore, it also revealed the influence of adhesion on dewetting phenomena during the laser transfer and relaxation process, resulting in polymer spots of various morphologies. This gives a general insight into polymer-surface adhesion and connects it with the generation of defined polymer microstructures, which can be a valuable reference for the rational use of polymers

The restructuring of schooling with digital technologies and implications for policy makers and practitioners

Traditional forms of schooling remain resistant to change because of the fit with their current ecologies. However, new forms of schooling that depend on communication technologies have emerged, including virtual schools and classes networked across collaborating schools (Davis, Eickelmann & Zaka, 2013). The purpose of this research had been to identify how technologies have resulted in the restructuring of many schools and what implications this has for teachers, local and national policy makers
