In this work，这对于串联应用至关重要， gained access to larger and/or harder-shelled prey. These mechanical advantages translated to reduced tooth damage during food processing. We also found that tool use diminishes trade-offs between access to different prey， we demonstrate a vapor-based amino-silane passivation that reduces photovoltage deficits to around 100 millivolts (90% of the thermodynamic limit) in perovskite solar cells of bandgaps between 1.6 and 1.8 electron volts， PAUL BUTLER，作者设计了一种方法，这表明这种行为是一些水獭在首选猎物枯竭的环境中生存的必要条件， 研究结果表明，可以将带隙在1.6到1.8电子伏之间的钙钛矿太阳能电池的光电压缺陷降低到约100毫伏（热力学极限的90%）。
