Polymers used for light-based 3D printing are very stable due to their chemical structure, but they are typically hard to recycle. A research team led by Prof. Dr. Eva Blasco, a researcher at the Institute for Molecular Systems Engineering and Advanced Materials (IMSEAM) at Heidelberg University, has now designed a polymer material that can be disassembled into its individual components when needed. A chemical “key” causes already printed material to break down into its molecular building blocks within seconds. They can be recovered and reused in a circular manufacturing process.

Developmental prosopagnosia is a neurodevelopmental condition in which individuals have lifelong difficulties in face processing, including identifying and remembering faces. In a recent study, researchers comprehensively evaluated the 20-item prosopagnosia index, which is a commonly used questionnaire for screening developmental prosopagnosia. Using established and advanced statistical methods, the researchers confirmed the questionnaire's reliability and validity and revealed opportunities to improve individual questions, paving the way for better and effective screening of the condition.
