“…Concurrent investigations of freeze-cast materials for other ceramic-based applications, including filtration membranes [6][7][8] and fuel cell electrodes [9][10][11][12][13][14][15][16], began to reveal the true versatility of the technique. Freeze-casting of metals [17], pharmaceuticals [18][19][20][21][22][23][24], and foodstuffs [25] was demonstrated within the same decade. From the early 2000's to 2017, the number and diversity of potential applications for these materials grew considerably; applications investigated include substrates for supercapacitors [26][27][28][29][30][31][32], photocatalysis [33][34][35][36][37][38][39][40][41][42][43], liquid chromatography [44], sensors (e.g.…”
