Edible Bioplastic with Natural pH Indicators

Bioplastic and Biopolymer Production

Biobased performance bioplastic: Mirel.

Each year over 140 million tons of petroleum-based polymers are produced worldwide and used in the production of such plasticsaspolyethylene, polystyrene, polyvinyl chloride, polyurethane, and others. Mostly using oil, coal, and natural gas as raw materials for their manufacturing, these plastics are common in every facet of our lives from the pharmaceutical industry to household use. Approxima...

Natural disasters and indicators of social cohesion

Do adversarial environmental conditions create social cohesion? We provide new answers to this question by exploiting spatial and temporal variation in exposure to earthquakes across Chile. Using a variety of methods and controlling for a number of socio-economic variables, we find that exposure to earthquakes has a positive effect on several indicators of social cohesion. Social cohesion incre...

Angle-independent pH-sensitive composites with natural gyroid structure

pH sensor is an important and practical device with a wide application in environmental protection field and biomedical industries. An efficient way to enhance the practicability of intelligent polymer composed pH sensor is to subtilize the three-dimensional microstructure of the materials, adding measurable features to visualize the output signal. In this work, C. rubi wing scales were combine...
