The mechanical properties of silk are determined by tight stacks of sheet-like peptide crystals distributed in amorphous regions. Here, the authors heat and stretch silk fibres to align these crystal into a long range ordered carbon structure and dramatically enhance the silk strength.
Reaction-diffusion controls the spatial formation of many natural structures but is rarely applied to organic materials. Here, the authors couple reaction-diffusion to the self-assembly of a supramolecular gelator, introducing a strategy to forming soft, free-standing objects with controlled shape and functionality.
Simple synthetic routes to polyaromatic hydrocarbons are important due to their applications in organic electronics. Here the authors report a straightforward synthesis of a diverse range of polyaromatic hydrocarbons, via a one-pot oxidative cyclisation and subsequent 1,2-aryl migration.
Computer networks, trained with data from delayed-fluorescence materials that have been successfully used in organic light-emitting diodes, facilitate the high-speed prediction of good emitters for display and lighting applications.
Organic photovoltaics are on the verge of revolutionizing building-integrated photovoltaics. However, for other applications, several basic open scientific questions need answering to, in particular, further improve energy-conversion efficiency and lifetime.
