Lee, J.K.W. (author), Tan, B. (author), Kingma, B.R.M. (author), Haman, F. (author), Epstein, Y. (author)Exposure to extreme environmental heat or cold during military activities can impose severe thermal strain, leading to impairments in task performance and increasing the risk of exertional heat (including heat stroke) and cold injuries that can be life-threatening. Substantial individual variability in physiological tolerance to thermal stress...article 2023

Houben, J. (author), Shkatulov, A. (author), Huinink, H. (author), Fischer, H. (author), Adan, O. (author)Potassium carbonate has recently been identified as a promising candidate for thermochemical energy storage. However, as for many salt hydrates, its reaction kinetics is relatively slow. KCO has a metastable zone, where the reaction is kinetically hindered, which limits the temperature operating window. This work aims to improve the material...article 2023

(author)This study investigates how cognitive performance is affected by the combination of two stressors that are operationally relevant for helicopter pilots: heat load and hypobaric hypoxia. Fifteen participants were exposed to: 1) no stressors, 2) heat load, 3) hypobaric hypoxia and 4) combined heat load and hypobaric hypoxia. Hypobaric hypoxia (13...article 2023

Mazur, N. (author), Huinink, H. (author), Fischer, H. (author), Adan, O. (author)This work investigates the reactions occurring in K2CO3–H2O–CO2 under ambient CO2 pressures in temperature and vapor pressure ranges applicable for domestic thermochemical heat storage. The investigation shows that depending on reaction conditions, the primary product of a reaction is K2CO3·1.5H2O, K2CO3·2KHCO3·1.5H2O, or a mixture of both. The...article 2022
