MRS Journal Highlights

2020 MRS bulletin  
The high interest on conformable and flexible electronics for a variety of sensor and design applications fit for the human body is producing a demand for new materials. The authors emphasize the environmental implications for new materials choices. There is a good development and identification of factors that can make this successful for eventual manufacturing. The authors present a method to exfoliate graphite to multilayer graphene within a polymer, creating functionalized

The strength and stiffness of the composite significantly exceed the matrix, and microscopy and chemical characterization are used to explain the effectiveness of the process. The mechanisms related to the mechanical performance degradation of bio-based hydrogels are evaluated. Oxidation and interaction with collagenase I are particularly effective at decreasing storage and loss modulus in a controlled manner while producing byproducts that have low toxicity, making these materials candidates for tissue compatible repair. A simple hydrothermal processing method to create photoluminescence crystals with novel "flower-like" surface morphologies is presented. Both the structure and the optical response of these materials are presented, resulting in a possible method to create low-cost phosphors using a process with low environmental impact.
