Electrochemical sensor for phosphate ions based on laser scriber reduced graphene oxide
This preliminary work shows a new and innovative way to produce laser scribed reduced graphene oxide (LSGO) electrodes using different porous substrates (ranging from paper to plastic and fabric). The obtained electrodes were also tested as electrochemical sensors towards the detection of phosphate ions in water. To obtain the electrodes, a water suspension of GO was filtered on top of substrate (such as Whatman® filter paper) and a complete sensor was obtained from its reduction using a CO2 laser. The electrode is composed of working and counter electrodes made of LSGO and a reference electrode of a Ag/AgCl obtained by using a commercial AgCl conductive paste. Phosphate ions were detected …
Operatori delle comunità con migranti. Competenze coss-culturali e digitali
La sfida lanciata in tema di migrazione, e di bisogni delle comunità multiculturali, è legata alla maturazione della consapevolezza relativa alla necessità che gli operatori che lavorano in questo ambito abbiano un’adeguata formazione
