Human adipose tissue–derived microvascular endothelial cells release [3H]-2-DG through a process involving glycogenolysis and glucose dephosphorylation. In contrast to the high level of phosphoryla-tion of [3H]-2-DG within HAMEC, the re-leased fraction was found to be predomi-nantly unphosphorylated (Figure 2G).

If the capacitor has a tendency to accumulate heat during operation, it will be more likely to reach the breakdown threshold, leading to the deterioration of energy storage performance [15]. This will lead to thermal runaway or sudden decrease in energy storage efficiency of the capacitor and even catastrophic failure of the capacitor [ 16, 17 ].
