Abstract To promote the real application of zinc‐ion batteries (ZIBs), reconciling high mass loading and gravimetric performance MnO 2 electrodes is paramount importance. Herein, rational regulation 3D‐printed carbon microlattices (3DP CMs) enabling an ultrathick electrode with well‐maintained capacities demonstrated. The 3DP CMs made graphene nanotubes (CNTs) are fabricated by direct ink 3D printing subsequent high‐temperature annealing. enables a periodic structure CMs, while thermal...
The Longzi River Basin in Tibet is located along the edge of Himalaya Mountains and characterized by complex geological conditions numerous landslides. To evaluate susceptibility landslide disasters this area, eight basic factors were analyzed comprehensively order to obtain a final map. are slope angle, aspect, plan curvature, distance-to-fault, distance-to-river, topographic relief, annual precipitation, lithology. Except for rainfall factor, which was extracted from grid cell, all...
Aqueous zinc-ion batteries (ZIBs) are considered as one of the ideal devices for large-scale energy storage because their safety, low cost, and nontoxicity. Unfortunately, choice cathode materials ZIBs is still limited. Herein, a novel oxygen vacancy-rich nitrogen-doped MnCO3 (MnCO3@N) microsphere reported material rechargeable ZIBs, which displays relatively high reversible capacity 171.6 mAh g-1 at 100 mA g-1, outstanding rate performance, long-term cyclic stability up to 1000 cycles g-1....
Abstract Tin (Sn) perovskites have emerged as promising alternatives to address the toxicity concerns associated with lead-based (Pb) perovskite light-emitting diodes (PeLEDs). However, inherent oxidation of Sn films leads a serious efficiency roll-off in PeLEDs at increased current densities. Although three-dimensional (3D) CsSnBr 3 exhibit decent carrier mobilities and thermal stability, their rapid crystallization during solution processing results inadequate surface coverage. This...
Abstract Tin (Sn) perovskites have emerged as viable candidates for high‐performance, lead‐free perovskite light‐emitting diodes (PeLEDs). However, the limited availability of efficient and stable Sn perovskites, development large‐area PeLEDs encourage further research. Here, FPEA 2 SnI 4 (FPEAI, 4‐fluoro‐phenethylammonium iodide) is reported a potential emitter PeLEDs. To overcome anisotropic carrier transport in layered an electronic push‐pull effect strategy introduced by incorporating...
Tin perovskite solar cells (TPSCs) have been facing challenges in power conversion efficiency (PCE) and long-term stability due to the easy oxidation of Sn2+ migration iodine ions, which create populated trap states cause detrimental recombination photogenerated carriers. In this work, we design a novel "molecular lock" suppress tin perovskites by introducing F-type pseudohalide tetrafluoroborate (BF4-) natural multifunctional antioxidant myricetin (C15H10O8). We find that incorporation BF4-...
As promising candidates for large-scale energy storage applications, aqueous zinc ion batteries (AZIBs) face challenges due to the electrochemical instability of cathode materials and Zn anodes. Introducing additives into electrolyte is an effective approach improving compatibility electrodes.
