(a) Representative thermal histories, where H₁ refers to the initial cooling rate between 12ºC and -100ºC, including experiments on DP6 + IONP (H₁ = -1 to -7.5°C/min) and DP6+sIONP (H₁ = -20°C/min), and where the reported temperature was measured at the inner surface of the cuvette. (b) A cryomacrograph of fractured DP6+sIONP (occurring at -123°C with H₁ = -20°C/min). (c) A cryomacrograph of partially crystallized VS55 in the absence of nanoparticles. Both cryomacrographs are presented in regular color scheme and a negative color scheme, which may enhance physical events.
