High-resolution multichannel seismic data enables the discovery of a previous,undocumented submarine canyon(Huaguang Canyon)in the Qiongdongnan Basin,northwest South China *** Huaguang Canyon with a NW orientation is 140 km in length,and 2.5 km to 5 km in width in its upper reach and 4.6 km to 9.5 km in width in its lower *** head of the Huaguang Canyon is close to the Xisha carbonate platform and its tail is adjacent to the central *** buried submarine canyon is formed by gravity flows from the Xisha carbonate platform when the sea level dropped in the early stage of the late Miocene(~10.5 Ma).The internal architecture of the Huaguang Canyon is mainly characterized by high amplitude reflections,indicating that this ancient submarine canyon was filled with coarse-grained *** sediment was principally scourced from the Xisha carbonate *** contrast to other buried large-scale submarine canyons(central canyon and Zhongjian Canyon)in the Qiongdongnan Basin,the Huaguang Canyon displays later formation time,smaller width and length,and single sediment *** coarse-grained deposits within Huaguang Canyon provide a good environment for reserving oil and gas,and the muddy fillings in Huaguang Canyon have been identified as regional ***,Huaguang Canyon is potential area for future hydrocarbon exploration in the northwest South China *** results may contribute to a better understanding of the evolution of submarine canyons formed in carbonate environment.

Random Terpolymer Based on Simple Siloxane-functionalized Thiophene Unit Enabling High-performance Non-fullerene Organic Solar Cells

Chinese Journal of Polymer Science 2024年第3期42卷 311-321,I0006页

Incorporation of siloxane-functionalized units into polymers backbone has proven to be an efficient strategy to improve photovoltaic performance. In this work, a low-cost siloxane-containing unit was developed to construct a series of terpolymers, and the effects of siloxane on the polymer performance were systematically studied. Different contents of thiophene containing siloxane-functionalized side chain were introduced into PM6 to obtain a series of polymers(PM6, PM6-SiO-10, PM6-SiO-20 and PM6-SiO-30). The siloxane-functionalized side chains in polymers have only a slight effect on the absorption behavior and frontier molecular orbitals. However, when the siloxane content increased, the terpolymers' aggregation property decreased and the temperature-dependency increased, leading to improved donor-acceptor compatibility. The power conversion efficiency(PCE) based on PM6:Y6, PM6-SiO-20:Y6 and PM6-SiO-30:Y6 devices was 15.64%, 16.03% and 15.82%, respectively. In comparison, the active layer based on PM6-SiO-10:Y6 exhibits the most appropriate phase separation morphology, resulting in effective exciton dissociation, more balanced hole-electron transport and less recombination. Consequently, the highest PCE of 16.69% with an outstanding shortcircuit current density of 26.96 mA·cm^(-2) was obtained, which are one of the highest values for siloxane-functionalized polymer-based *** work demonstrates that finely controlling the content of siloxane-functionalized thiophene is beneficial for obtaining high-performance terpolymer donors and provides a novel and low-cost method to improve photovoltaic performance.

近年来,全球原油供应格局在地缘政治格局动荡下发生重要调整。中东地区作为欧佩克的主要阵地,仍是全球石油供应的重要调节阀,但随着减产规模扩大,其市场份额显著下降;美洲地区原油产量跃升,美国、加拿大、巴西、圭亚那等国是全球原油新增供应的主要贡献者;非洲主要产油国产量迅速衰减,市场份额流失,尼日利亚和安哥拉在全球市场中的地位急剧下降;独联体地区受乌克兰危机影响,贸易流向发生根本性变化,但市场份额基本保持稳定。当前中国已经形成较为稳定的进口来源渠道,但原油进口依存度较高,进口来源地较为集中,地缘政治冲突对中国原油进口形成严峻挑战。为保障国家能源安全和经济稳定发展,建议持续推进国内油气增储上产,提高国内资源自给能力;优化提升全球原油资源配置,做好资源经济性采购;形成地缘政治风险预警机制,提升资源安全供应能力。

单质硫及其放电最终产物Li_(2)S的绝缘性以及两者密度差异引起的结构坍塌等问题严重阻碍了锂硫电池的进一步发展,找寻合适的基体材料是解决上述问题的有效策略。本工作选用一种蜂窝状多孔碳作为硫正极的基体材料,通过常规的熔融扩散法将硫单质固定在碳孔隙中,并利用SEM、XRD、XPS和BET等方法对多孔碳@单质硫复合材料进行了表征。结果表明,硫单质均匀地负载在碳骨架中。同时,蜂窝状结构碳不仅为硫单质提供了电子导电网络,也保证了正极的稳定性。更重要的是,蜂窝状的结构为循环过程中硫正极的体积膨胀提供了一定的缓冲空间,缓解了结构坍塌这一问题。此外,碳基体丰富的孔隙度在一定程度上减少了多硫化物的穿梭。因此,在0.1C的倍率下,多孔碳@单质硫复合材料首次放电比容量高达1125.9 mAh/g,300次循环后比容量可保持305.1 mAh/g。
