Design, Synthesis and Application of Novel Degradable Materials Based on Polyesters by Radical Ring-Opening Polymerization
Design, synthesis and application of novel degradable material based on polyesters by radical ring-opening polymerization (RROP) were described in this thesis. Herein, we studied a rare example of the formation of polystyrene-grafted aliphatic polyester in one-pot by radical polymerization …

Design of Cleavable Monomers and Cross-Linkers for the Synthesis of Degradable Polymer Architectures
Degradable materials, with different chemical compositions and various polymer architectures, are desirable for countless purposes, ranging from biological applications to recyclability of plastic waste. The creation of brand-new materials with useful, desired properties and built-in degradability …

Peripheral nerve regeneration through collagen devices with different in vivo degradation characteristics
… restore lost function. A variety of degradable and non-degradable materials have been used to fabricate the tubes used to bridge the stumps of a transected nerve, and collagen tubes have been specifically shown to improve the quality of regeneration. The optimal characteristics for …

Materials for bioimplantable / bioresorbable electronics
Recent advances in materials, mechanics design and microfabrication technologies are beginning to establish the foundations for electronics of thin layouts that conformally interface with the human organs including the brain, the heart and epidermis. Certain of the thin materials including silicon …

Impact of Freeze-Thaw Cycles on Porosity Change in Shalles and Its Implications on Erodibility
… can expose near-surface shales, which are highly degradable materials. Initially, these cuts appear stable, but the material can quickly weather into loose sediment. Predicting this degradation is essential because intact shale is a stable, non-erodible geomaterial, whereas weathered sediment is …
