“…Ga and its alloys have been proposed as replacements for Hg in dental filling materials [ 18 , 19 , 20 ] and high-temperature thermometers [ 21 , 22 , 23 , 24 ]. Ga and Ga-based alloys have also been studied as potential coolants in nuclear power plants as an alternative to Na [ 10 , 25 , 26 , 27 , 28 , 29 ], and in microelectronic devices, such as computers and smart phones [ 30 , 31 , 32 , 33 , 34 , 35 ]. Eutectic Ga-In (EGaIn) alloys and Ga-In-Sn alloys (such as Galinstan) have received the most attention in the literature in terms of microelectronic applications.…”
