Amorphous guanine was proposed to be the mineralization precursor of biological anhydrous guanine β phase in vesica of the Koi fish scales1. Guanine is the most widespread organic crystal existing in organisms to produce structural colors. Guanine monohydrate and two anhydrous guanine phases (AG), and , are three well known crystalline phases of guanine. The...

Control of Molar Mass Distribution in Polymers

Andreas Spinnrock and Helmut Cölfen, University of Konstanz, Germany, have combined analytical ultracentrifugation (AUC) with polymer chemistry to obtain desired broad molar mass distributions. The analytical ultracentrifugation was used to adjust a macroinitiator's concentration gradient to control the molar mass distribution after subsequent polymerization. Depending on the rotational speed, the macroinitiator forms the desired concentration gradient. It can be detected at any point by optical...

Nature’s blueprint

Based on the nanostructure of the sea urchin spines, the research team Physical Chemistry at the University of Konstanz develops cement that is significantly more fracture-resistant.
