We present a self-consistent model for explosive financial bubbles, which combines a mean-reverting volatility process and a stochastic conditional return which reflects nonlinear positive feedbacks and continuous updates of the investors' beliefs and sentiments. The conditional expected returns...

Aiming at the issues and defects triggered by the single power form of a traditional electric vehicle, a planetary gear-based master-slave electrohydraulic power-coupled electric vehicle (MS-EHPCV) was proposed. MS-EHPCV can decrease the peak torque during the frequent start-stop process and...

Abstract ; Nickel oxide (NiO x ) is one of the most promising inorganic hole transport layers for perovskite solar cells (PSCs), due to its low cost, high hole mobility, and superior stability. However, the mismatched energy level and undesirable chemical reaction at the NiO x /perovskite...

All-solid-state lithium batteries (ASSLBs) have become one of the most promising next-generation energy storage devices owing to their high energy density and inherent safety. However, the uneven growth of lithium dendrites and large interface impedance between electrolyte and electrode easily...

Advanced oxidation processes based on sulfate radicals were promising technologies for deep wastewater treatment. There was an urgent need of low-cost and green catalytic material. In this study, N-doped low-rank coal based carbon catalysts (NLCs) were prepared under different ratios and...
