Dose-effect relationship of edible fungi with low-energy heavy-ion implantation

Fushe yanjiu yu fushe gongyi xuebao, 2021
To reveal the dose-effect relationship of edible fungi via low-energy heavy-ion implantation, the conidia of three species of edible fungi were irradiated with 15 keV nitrogen ions at different dosages (0, 2, 4, 6, 8, 10, 12, and 14)×1015 cm-2.

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

Advanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.
