As temperature rises, the number of phonons increases and with it the likelihood that the electrons and phonons will collide. Thuswhen temperature goes up, resistance goes up. For some materials, resistivity is a linear function of temperature. The resistivity of a conductor increases with temperatu...
Resistivity is the electrical resistance of a conducting material per unit length. In other words, it is the degree to which a conductor opposes the flow of electricity through itself, instead allowing the energy to flow out of the electrical circuit, most often as heat. Resistivity is useful ...

16. Although all-perovskite tandem solar cells have achieved a certified PCE of over 30%, their stability remains insufficient for commercial viability. This limitation is mainly due to the instability of their bottom subcells, which use narrow-bandgap perovskites incorporating...
‘Ghost cities’ are a well-known phenomenon of (almost) complete vacancy of urban living space in China. Underutilization of urban living space, however, is far more common than complete vacancy. Here we propose the concept of housing utilization efficiency (HUE) and present the following findin...
With the wire increases above the ground, conductor to ground the electric field strength of a reducing trend 翻译结果4复制译文编辑译文朗读译文返回顶部 Along with the height of the wire and the wire on the ground increases the electric field strength is smaller trends 翻译结果5复制译文编辑译文朗...
a在退火或热轧状态下﹐随含碳量的增加﹐钢的强度和硬度升高﹐而塑性和冲击韧性下降 ﹐﹐ The plasticity and the resilience drops but under the annealing or the hot rolling condition along with the carbon amount increase ﹐ steel intensity and degree of hardness ascension [translate] ...
When faced with complex choices or overwhelming options, we might defer decisions indefinitely, seeking the "perfect" solution. Evidence-Based Solutions 1. Implementation Intentions Research shows that creating specific "if-then" plans dramatically increases follow-through. Instead of vague intentions, cre...
XRD patterns of the diamonds phase transformed from OC precursors with average size of 22 nm (a), 38 nm (b) and 46 nm (c). As the precursor particle size diminishes, a conspicuous broadening of the full width at half maximum in the XRD peaks of the resulted samples is observed...
Networks of metallic nanowires have the potential to meet the needs of next-generation device technologies that require flexible transparent conductors. At present, there does not exist a first principles model capable of predicting the electro-optical performance of a nanowire network. Here we combine...
