GC: Scientists created semiconductors from birch leaves

Team of the Swedish scientists from Umeo's University Umeå together with colleagues from Denmark and China developed a method of productions organic semiconductors from birch leaves. Their scientific work is published in the Green Chemistry (GC) magazine. Usually organic semiconductors make of petrochemical connections and rare metals, for example, of platinum and iridium. They are applied in the organic light-emitting diodes (OLED) used in ultrathin and bright screens of TVs and mobile phones. Scientists collected foliage of usual birches, prepared it in the autoclave at high temperature and big pressure...
