The result is disease, particularly diarrhoea. This kills millions of children a year and stunts the growth of millions more. Better water filters, then, could save many lives and improve many others, and Yi Cui of Stanford University thinks he has come up with one.

Dr Cui’s filter, though, does not screen the bacteria out. It kills them. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
