Az okostelefonok k\u00e9perny\u0151i \u00e9s a napelemek gyakran olyan ritka \u00e9s ez\u00e9rt dr\u00e1ga nemesf\u00e9meket tartalmaznak, mint az ir\u00eddium vagy a rut\u00e9nium.<\/p>\n\n\n\n

Az ir\u00eddium, amelyet az OLED-ekben (szerves f\u00e9nykibocs\u00e1t\u00f3 di\u00f3d\u00e1kban) vetnek be, ritk\u00e1bb, mint az arany \u00e9s a platina. A rut\u00e9nium, melyet napelemekben haszn\u00e1lnak, a legritk\u00e1bb stabil elemek egyike. Nem el\u00e9g, hogy ritkas\u00e1guk miatt nagyon dr\u00e1g\u00e1k, ezek a f\u00e9mek sok vegy\u00fcletben m\u00e9rgez\u0151ek is.<\/p>\n\n\n\n

A B\u00e1zeli Egyetem kutat\u00f3inak, Oliver Wengernek \u00e9s Patrick Herrnek el\u0151sz\u00f6r siker\u00fclt l\u00e9trehozniuk olyan vil\u00e1g\u00edt\u00f3 mang\u00e1nkomplexet, melyben f\u00e9nnyel val\u00f3 besug\u00e1rz\u00e1s hat\u00e1s\u00e1ra ugyanolyan reakci\u00f3k j\u00e1tsz\u00f3dnak le, mint a rut\u00e9nium- vagy ir\u00eddium-vegy\u00fcletekben.<\/p>\n\n\n\n

Komplexnek h\u00edvj\u00e1k azokat a vegy\u00fcleteket, amelyekben koordinat\u00edv k\u00f6t\u00e9ssel ligandumok kapcsol\u00f3dnak a k\u00f6z\u00e9ppontban l\u00e9v\u0151 atomhoz, ionhoz. A tud\u00f3sok eredm\u00e9nyeikr\u0151l a Nature Chemistry c\u00edm\u0171 tudom\u00e1nyos lapban sz\u00e1moltak be.<\/p>\n\n\n\n

A mang\u00e1n el\u0151nye, hogy a f\u00f6ldk\u00e9regben 900 ezerszer gyakrabban fordul el\u0151, mint az ir\u00eddium, l\u00e9nyegesen kev\u00e9sb\u00e9 m\u00e9rgez\u0151 \u00e9s j\u00f3val olcs\u00f3bb is. Kor\u00e1bban senkinek sem siker\u00fclt mang\u00e1nnal olyan molekul\u00e1ris komplexet l\u00e9trehozni, amely szobah\u0151m\u00e9rs\u00e9kleten oldatban vil\u00e1g\u00edt, \u00e9s speci\u00e1lis reakci\u00f3s tulajdons\u00e1gokkal rendelkezik \u2013 mondta Wenger.<\/p>\n\n\n\n
