Li-O_(2)batteries with high energy density hold significant promise as next-generation energy storage ***,Li-O_(2)batteries have poor cycling performance at high current densities and large capacities,primarily due to the high impedance caused by the instability of the lithium anode and the sluggish kinetics in the discharge products decomposition on the ***,we investigated a bifunctional nitrile additive(2-methoxy benzonitrile(2-MBN))with good chemical/electrochemical stability to improve the performances of Li-O_(2)*** 2-MBN could actively modify the anode by ensuring uniform Li+deposition and optimizing the composition of solid electrolyte interphase(SEI).Meanwhile,it could also facilitate the decomposition of discharge products by inducing the formation of sheet-like Li_(2)O_(2),significantly reducing the battery charge *** bifunctional effects of 2-MBN for the anode and cathode enable Li-O_(2)batteries to achieve a stable lifetime of 97 cycles at a current density of 600 mA·g^(−1)with a fixed capacity of 2000 mAh·g^(−1),much better than that of Li-O_(2)batteries without 2-MBN(28 cycles).The inclusion of 2-MBN provides an effective approach for attaining high-performance Li-O_(2)batteries.

Organic electrode molecules hold significant potential as the next generation of cathode materials for Li-ion batteries. In this study, we have introduced a multi-objective active learning framework that leverages Bayesian optimization and non-dominated sorting genetic algorithms-II. This framework enables the selection of organic molecules characterized by high theoretical energy density and low gap(LUMO-HOMO)(LUMO, lowest unoccupied molecular orbital; HOMO, highest occupied molecular orbital). Remarkably, after only two cycles of active learning, the determination of coefficient can reach 0.962 for theoretical energy density and 0.920 for the gap with a modest dataset of 300 molecules, showcasing superior predictive capabilities. The 2,3,5,6-tetrafluorocyclohexa-2,5-diene-1,4-dione, selected by non-dominated sorting genetic algorithms-II, has been successfully applied to Li-ion batteries as cathode materials, demonstrating a high capacity of 288 m Ah g-1and a long cycle life of 1,000 cycles. This outcome underscores the high reliability of our framework. Furthermore, we have also validated the universality and transferability of our framework by applying it to two additional databases, the QM9 and OMEAD. When the training dataset of the model includes at least 500 molecules, the determination of coefficient essentially reaches approximately0.900 for four targets: gap, reduction potential, LUMO, and HOMO. Therefore, the universal framework in our work provides innovative insights applicable to other domains to expedite the screening process for target materials.

在自然条件下,山羊中存在无角变异,与其他牛科动物不同,山羊的无角性状与间性性状紧密相连,被称为PIS(无角间性综合征)。大量研究发现,PIS序列与山羊的无角间性性状密切相关。山羊间性是一种严重的繁殖障碍,多发生于无角山羊,对无角山羊的选育和产业发展带来极大的阻碍。因此,揭示山羊无角间性性状的遗传机制对无角山羊产业发展至关重要。本文综述了几个品种无角山羊无角间性性状的研究方法、遗传机制和鉴定方法,为阐明山羊无角性状的遗传机制提供理论支持,为无角山羊的选育提供参考。
