Exothermic dark matter for XENON1T excess

Journal of High Energy Physics, 2021
Motivated by the recent excess in the electron recoil from XENON1T experiment, we consider the possibility of exothermic dark matter, which is composed of two states with mass splitting.

Effects of Changing Size-Weight Parameters on the Temperature Dependent Exothermic Riser Sleeve Properties

Eurasian Chemico-Technological Journal, 2018
Exothermic riser (feeder) sleeves are used to retain the heat in risers and to increase solidification duration. A riser should be enough hot to become the last solidified part in a mould cavity.

Controllable synthesis of SiC wrapped LDHs to reinforce microwave absorption and exothermic properties of styrene-butadiene-styrene (SBS) polymer modified asphalt

Materials Research Express, 2021
Combination of styrene-butadiene-styrene (SBS) polymer and layered double hydroxides (LDHs) has commonly applied in asphalt to improve anti-ultraviolet aging performance, but it can not afford the reparation of cracks caused by aging of asphalt.
