When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).Examples of Endothermic and Exothermic Processes Photosynthesis is an example of an ...
Upon water addition the transport direction changes from exothermic to endothermic, i.e. from retrograde to normal temperature dependence of the solubility, demonstrating that even a small amount of oxygen can have a fundamental influence during ammonobasic synthesis....

The DTA results (Fig. S2a, Supporting information) indicate that BiMgO-2MBD (X = 0.42) underwent exothermic processes at 294 °C, which might be due to the crystallization or phase transition of the metal oxide substrate [66]. The observed endothermic process at 398 °C gives insights ...
