Chemical Leaching from Tire Wear Particles with Various Treadwear Ratings
International Journal of Environmental Research and Public Health, 2022 Physical friction between a tire and the road surface generates tire wear particles (TWPs), which are a source of microplastics and particulate matter. This study investigated the trends of chemical leaching from TWPs depending on the treadwear rating of the tire.

Temperature Effect on Plutonium Leach Rate of Nuclear Waste Glass [PDF]
Journal of Nuclear Science and Technology, 1989 The two kinds of nuclear waste glass with similar composition, a 238Pu-doped and non-radioactive waste glass, were leached under the ISO-test conditions at temperature between 23 and 90°C. An activation energy of 22±10 kJ/mole was obtained from the initial leach rates of Pu, which was much lower than the 78±9 kJ/mole obtained from those of Si, Na, Sr ...
