Dimerized small-molecule acceptors(SMAs) built by the conventional connection of terminal groups of monomers have contributed to exciting long-term stabilities of organic solar cells(OSCs). However, device efficiencies, especially fill factors(FFs), still need to be improved. This probably originates from unsymmetrical molecular structure/conformation-determined less compact/ordered molecular stackings, such as ineffective stackings of constraint terminals. Herein, an exotic dimerized SMA of BC-Th is established by bridging the branched groups(BC-type, branch coupling) of two monomers rather than conventional terminal units(TC-type, terminal coupling). Benefiting from the three-dimensional conformation and more uncurbed terminals,BC-Th exhibits multiple molecular orientations along with a larger dielectric constant and electron mobility compared with TCTh. Finally, an efficiency of 17.43% is achieved by BC-Th-based OSCs, along with the highest FF of 79.13% among all dimerized SMAs-based OSCs to date. When introducing l8-BO as the third component, overall enhanced efficiency of 18.05%and FF of 80.11% are further afforded. Contrarily, TC-Th-based OSCs exhibit much inferior PCE of 16.29% and FF of 74.81%,demonstrating the great advantages of “branch coupling” over “terminal coupling” when building dimerized SMAs.

Zircon U-Pb-Hf and trace element signatures reveal the petrogenesis of the Jiuyishan granitic complex， South China: Implications for W-Sn and rare metal mineralization

Journal of Earth Science 2024年

The Jiuyishan granitic complex， located in the Nanling Range， South China， is composed of five granitic plutons （Xuehuading， Jinjiling， Pangxiemu， Shaziling and Xishan）. Zircon U-Pb dating of four plutons （Jinjiling， Pangxiemu， Shaziling and Xishan） yielded similar ages of approximately 153 Ma， indicating indistinguishable ages within error. Three plutons except the Shaziling pluton， have consistent εNd（t）（-7.8 to -5.8） and εHf（t）（-9.1 to -2.2） values， which are similar to those of the lower crustal granulitic metasedimentary and meta-igneous rocks in South China. Comparing to other three plutons， the Shaziling pluton has consistent εHf（t）（-7.4 to -6.8） and εHf（t）（-7.5 to -4.7） values and shows similar source， but the Shaziling mafic microgranular enclaves （MMEs） show variable εHf（t）（-14.2 to 4.8） values， indicating a remarkable mantle magma injection of the Shaziling pluton. Zircon Ce/Sm-Yb/Gd， whole-rock CaO-P2O5and CaO-TiO2linear trends revealed that from the Xishan to the Shaziling and from the Jinjiling to the Pangxiemu granites， they experienced apatite and titanite fractionation， respectively. Zircon Th， U， Nb， Ta， Hf， Ti， Y， P and rare earth element （REE） contents and whole-rock Sr， Ba and Rb contents also show that the Shazling， Xishan， Jinjiling and Pangxiemu granites followed a discontinuous evolutionary series， but the Pangxiemu granites exhibit highly evolved nature. Four main controlling factors of W-Sn and rare metal mineralization in granitic rocks were discussed， and we found that the mineralization in Jiuyishan granitic complex was mainly controlled by the fractionation degree and crystallization temperature， but were rarely affected by oxygen fugacity and mantle material input. The Pangxiemu granites show particularly higher Rb and Ta contents than the other three plutons， implying that the ore deposits developed in the Jiuyishan complex were directly related to the most evolved Pangxiemu pluton， with the occurrence of Rb and Ta as the most l

Electro-oxidation of 5-hydroxymethylfurfural in a low-concentrated alkaline electrolyte by enhancing hydroxyl adsorption over a single-atom supported catalyst

引用

SCIENCE BUllETIN 2024年第18期69卷 2870-2880页

作者： Xia, Xiaoxia Xu, Jingyi Yu, Xinru Yang, Jing li, An-Zhen Ji, Kaiyue li, lei Ma, Min Shao, Qian Ge, Ruixiang duan, Haohong Shandong Univ Sci & Technol Coll Chem & Biol Engn Qingdao 266590 Peoples R China Tsinghua Univ Dept Chem Beijing 100084 Peoples R China Univ Sci & Technol China Hefei Natl Res Ctr Phys Sci Microscale Hefei 230026 Peoples R China Shandong Univ Sci & Technol Coll Mat Sci & Engn Qingdao 266590 Peoples R China

Electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA), a sustainable strategy to produce bio-based plastic monomer, is always conducted in a high-concentration alkaline solution (1.0 mol l-1 KOH) for high activity. However, such high concentration of alkali poses challenges including HMF degradation and high operation costs associated with product separation. Herein, we report a single-atom-ruthenium supported on Co3O4 (Ru-1-Co3O4) as a catalyst that works efficiently in a low-concentration alkaline electrolyte (0.1 mol l-1 KOH), exhibiting a low potential of 1.191 V versus a reversible hydrogen electrode to achieve 10 mA cm(-)(2) in 0.1 mol l-1 KOH, which outperforms previous catalysts. Electrochemical studies demonstrate that single-atom-Ru significantly enhances hydroxyl (OH-) adsorption with insufficient OH- supply, thus improving HMF oxidation. To showcase the potential of Ru-1-Co3O4 catalyst, we demonstrate its high efficiency in a flow reactor under industrially relevant conditions. Eventually, techno-economic analysis shows that substitution of the conventional 1.0 mol l-1 KOH with 0.1 mol l-1 KOH electrolyte may significantly reduce the minimum selling price of FDCA by 21.0%. This work demonstrates an efficient catalyst design for electrooxidation of biomass working without using strong alkaline electrolyte that may contribute to more economic biomass electro-valorization.

明确太湖胥口湾水质特征及对环境变化的响应有利于维系区域水资源安全。研究追踪2016—2022年胥口湾水质变化趋势,分析了水质指标对水温和水位的响应。结果显示,胥口湾水质环境总体稳定,且总氮(TN)、氨氮(NH_(3)-N)、总磷(TP)浓度和COD_(Mn)均呈下降趋势。但胥口湾水温年均值呈现快速上升趋势,上升幅度大于0.086℃·a^(-1),对该区域生态稳定性形成威胁。冗余分析显示,虽然水温和水位对胥口湾水质环境波动的贡献率低于5%,但水温变化显著影响了水质环境(P30℃)较为敏感,而高水位(>3.8 m)显著影响了NH_(3)-N、TN、TP和叶绿素a浓度。总体而言,胥口湾水环境总体稳定趋好,但受水位尤其是水温影响较大。研究结果可为极端天气下水质管理提供借鉴。
