富勒烯衍生物,尤其是[1,1]苯基-C_(61)-丁酸-甲酯(PC_(61)BM),通常用作反式(p-i-n)钙钛矿太阳能电池(PVKSCs)的电子传输层和添加剂,但PC_(61)BM(3.8)的介电常数(ε_(r))远小于有机无机杂化铅卤钙钛矿(CH_(3)NH_(3)PbI_(3)[MAPbI_(3)]为6.5)的介电常数,不利于激子的解离且阻碍了界面电荷的传输.本文中,我们合成了一种新的氰基功能化富勒烯,其中两个氰基通过罗丹宁连接到富勒烯上(缩写为C_(60)-Rhd-CN),并通过反溶剂法将其引入MAPbI_(3)活性层中来构建反式钙钛矿太阳能电池器件.引入强吸电子氰基后,C_(60)-Rhd-CN的ε_(r)值达到5.1,明显高于PC_(61)BM(3.8),因此可以有效降低MAPbI_(3)钙钛矿和富勒烯电子传输层之间的介电失配.此外,氰基能够与MAPbI_(3)钙钛矿中的Pb^(2+)离子进行配位实现钙钛矿的缺陷钝化.最终,C_(60)-Rhd-CN掺入钙钛矿后促进了激子解离和界面电荷传输,并抑制了非辐射复合,使反式钙钛矿太阳能电池器件的能量转换效率从参比器件的18.43%显著提高到20.81%.此外,掺入C_(60)-Rhd-CN有助于提高钙钛矿太阳能电池的环境和热稳定性.为了阐明氰基在增加ε_(r)值和提高效率方面的关键作用,我们还合成了另一种类似结构的新型罗丹宁官能化富勒烯,其中两个氰基被硫原子取代(缩写为C_(60)-Rhd-S),其获得的能量转换效率为19.45%,其性能低于含有C_(60)-Rhd-CN添加剂的钙钛矿太阳能电池的主要原因是其ε_(r)值(4.0)较低.

Achieving high maize yields and efficient phosphorus(P)use with limited environmental impacts is one of the greatest challenges in sustainable maize *** plant density is considered an effective approach for achieving high maize ***,the low mobility of P in soils and the scarcity of natural P resources have hindered the development of methods that can simultaneously optimize P use and mitigate the P-related environmental footprint at high plant *** this study,meta-analysis and substance flow analysis were conducted to evaluate the effects of different types of mineral P fertilizer on maize yield at varying plant densities and assess the flow of P from rock phosphate mining to P fertilizer use for maize production in China.A significantly higher yield was obtained at higher plant densities than at lower plant *** application of single superphosphate,triple super-phosphate,and calcium magnesium phosphate at high plant densities resulted in higher yields and a smaller environmental footprint than the application of diammonium phosphate and monoammonium *** scenario analyses suggest that combining the optimal P type and application rate with a high plant density could increase maize yield by 22%.Further,the P resource use efficiency throughout the P supply chain increased by 39%,whereas the P-related environmental footprint decreased by 33%.Thus,simultaneously optimizing the P type and application rate at high plant densities achieved multiple objectives during maize production,indicating that combining P management with cropping techniques is a practical approach to sustainable maize *** findings offer strategic,synergistic options for achieving sustainable agricultural development.

Exploring a universal strategy to increase Li-ion storage capacity and ionic conductivity while maintaining a robust crystal framework is a significant challenge for advancing Wadsley-Roth shear phases as promising anodes for high-power lithium-ion batteries. Here we report a potent cation-engineering driven crystallographic shear structure tailoring strategy, demonstrated through a novel titanium niobium tungsten oxide (TNWO). This is a significant model containing inspiring domains with tetrahedron, tetrahedron-free and large-size blocks in the lattice. Theoretical calculations reveal that the TNWO model, featuring the partial absence of a [WO4] tetrahedron and intrinsic multiple cation features, not only exhibits enhanced electronic conductivity and alleviated Li+ adsorbed structural distortion, but also facilitates both horizontal inter-block type and vertical-tunnel type Li+ diffusions, accompanied by sufficient redox reactions. Accordingly, it offers 1.48 Li+ per metal atom along with a high Li+ diffusion coefficient of 10−12 cm−2 s−1 and remarkable structural stability, featuring a reversible spatial phase transition. Additionally, through modification of surface anisotropy, dimensional uniformity and electronic conductivity of individual TNWO particles, a composite anode demonstrates ultrahigh rate capability (103.7 mA h g−1 at 15 A g−1) and excellent cycling stability (capacity retention of 80% at 5 A g−1 over 4900 cycles). This work is believed to have opened a new avenue for tailoring shear structures and creating unprecedented phases to transcend the existing Wadsley-Roth niobium-based oxide system for next-generation high-power lithium-ion batteries. © 2024 The Royal Society of Chemistry.
