Abstract
While the new cubic phase of tin monosulfide, π-SnS, shows potential for various applications, not much work was focused on the phase transitions, thermal stability, and thermal properties of π-SnS. In this work, we addressed these issues using temperature-resolved in situ X-ray diffraction combined with thermo-gravimetric differential scanning calorimetry and thermo-gravimetric infrared spectroscopy. The cubic π-SnS phase nanoparticles capped with polyvinylpyrrolidone were proven stable for 12 hours at 400 °C, pointing out the possible utilization of this new cubic phase at elevated temperatures. At the same time, heating above this temperature resulted in a phase transition to the high-temperature orthorhombic β-SnS phase. Subsequent cooling to room temperature led to an additional phase transition to the stable orthorhombic α-SnS phase. Interestingly, heating-induced phase transformation of π-SnS nanoparticles always resulted in β-SnS, even at temperatures below the α- to β-SnS equilibrium transition temperature. It was shown that surfactant decomposition and evaporation triggers the phase transition. Several thermal parameters were calculated, including the phase transition activation energy and the thermal expansion of the unit cell parameter of π-SnS.

Abstract
Colloidal synthesis of nanoparticles (NP) has advanced tremendously over the past 25 years, with an increasing number of research papers introducing nanomaterials with a variety of compositions, shapes, sizes, and phases. Although much progress has been achieved, commonly used synthetic procedures often fail to reproduce results, and the fine details of the syntheses are often disregarded. Reproducibility issues in synthesis can be ascribed to the effects of impurities, trace amounts of chemical moieties which significantly affect the reaction products. Impurities in NP synthesis are rarely reported or regularly studied, despite their impact, deleterious, or beneficial. This topical review discusses several case studies of colloidal NP synthesis where the sources and the chemistry of impurities are highlighted, and their role is examined.
