چکیده

Abstract Ubiquitous use of electronic devices has led to an unprecedented increase in related waste as well the worldwide depletion reserves key chemical elements required their manufacturing. The biodegradable and abundant organic (carbon-based) materials can contribute alleviate environmental impact industry. pigment eumelanin is a bio-sourced candidate for environmentally benign (green) electronics. biodegradation extracted from cuttlefish ink studied both at 25 °C (mesophilic conditions) 58 (thermophilic following ASTM D5338 comparatively evaluated with two synthetic materials, namely copper (II) phthalocyanine (Cu–Pc) polyphenylene sulfide (PPS). Eumelanin reaches 4.1% (25 °C) 97 days 37% (58 98 days, residual material found be without phytotoxic effects. Cu–Pc PPS, do not biodegrade; brings about inhibition microbial respiration compost. PPS appears potentially phytotoxic. Finally, some considerations regarding test disambiguation “biodegradability” “bioresorbability” are highlighted.

Alternating current thin-film electroluminescent (AC-TFEL) devices already occupy a segment of the large-area, high-resolution, flat-panel-display market. The AC-TFEL displays, which consist of a phosphor layer, such as manganese doped-zinc sulfide (ZnS:Mn), vertically sandwiched between two insulators that are contacted by electrodes, are robust, possess long lifetimes, and offer high luminanc...

Organic and Molecular Electronics

Over recent years, a wide variety of challenges aiming for electrical pumping of organic laser diodes have been addressed. However, organic laser diodes have difficulty gaining widespread application due to their high lasing thresholds under electrical pumping. A variety of organic semiconductors have been developed to reduce the lasing threshold, which include not only small molecular material...
