It has been widely recognized that hole transporting materials(HTMs)play a key role in the rapid progress of perovskite solar cells(PVSCs).However,common organic HTMs such as spiro-OMe TAD not only suffer from high synthetic costs,but also usually require the additional chemical doping process to improve their hole transport ability,which unfortunately induces the terrible stability ***,it is urgent to develop low-cost dopant-free HTMs for efficient and stable *** this work,we have successfully developed a new class of efficient dopant-free fluoranthene-based HTMs(TPF1–5)with quite low lab synthetic costs by combining donor-acceptor and branched structure *** detailed structure-property study revealed that tuning the twisted arms at different substitution sites would regulate the intermolecular interactions and film-forming ability,thereby significantly affecting the performance of the *** applying these HTMs in conventional PVSCs,the dopant-free TPF1-based devices not only achieved the best efficiency of 21.76%,which is comparable to that of the doped spiro-OMeTAD control devices,but also showed much better operational stability,which maintained over 87%of the initial efficiency under maximum power point tracking after 1038 h.

The development of adsorbent materials for effective capture of radioactive iodomethane(CH_(3)I) from the off-gas of used nuclear fuel reprocessing, remains a significant and challenging line of research because currently state-of-art adsorbents still suffer from low binding affinity with CH_(3)I. Here, we proposed a brand-new adsorption topological structure by developing a 2D interdigitated layered framework, named SCU-20, featuring slide-like channel with multiple active sites for CH_(3)I capture. The responsive rotating-adaptive aperture of SCU-20 enables the optimal utilization of all active sites within the pore for highly selective recognition and capture of CH_(3)I. A record-breaking CH_(3)I uptake capacity of 1.84 g/g was achieved under static sorption conditions with saturated CH_(3)I vapor. Both experimental and theoretical findings demonstrated that the exceptional uptake of SCU-20 towards CH_(3)I can be attributed to the confined physical electrostatic adsorption of F sites, coupled with the chemical nitrogen methylation reaction with uncoordinated N atoms of pyrazine. Moreover, dynamic CH_(3)I uptake capacity potentially allows for the capture of CH_(3)I in simulated real-world off gas reprocessing conditions. This study highlights the potential of SCU-20 as a promising candidate for efficient capture of iodine species and contributes to the development of effective solutions for radioactive iodine remediation.

随钻地质导向技术(LWD)是20世纪90年代发展起来的前沿技术,在高陡复杂构造上钻水平井,及时准确了解地层产状、识别储层特性,引导水平井的井眼轨迹沿着有效储层钻进是LWD数据解释的关键内容。为此,以四川盆地川东地区钻探石炭系的高陡构造为例,在对区域地质特征、构造背景和储层特征及分布规律的深入细致分析基础上,应用地震、录井、测井资料建立起了钻探目的层段的岩—电模型、钻前三维地质导向的井眼轨迹模型。实钻中,把钻前建立的目的层岩—电模型与随钻实时测量的自然伽马、电阻率信息进行对比,及时分析钻头所钻岩性在岩—电模型中的位置,判断井眼轨迹与地层相切关系,进而用电阻率信息分析储层特性来指导钻进井眼轨迹实时调整,确保水平井段有效储层的钻遇率。该导向模型的建立与数据解释的方法可供类似探区参考。

在传统的无线传感器网络中,有限的电池能量会限制传感器网络的寿命。而在无线可充电传感器网络中,能量可以通过无线方式给传感器充电,延长传感器网络的寿命。利用充电小车等移动设备对无线传感器网络进行能量补充时,在一个充电周期内减小充电小车的移动总路径,可以有效减少经济成本。基于无线可充电传感网中各节点的能耗差异性,结合蚁群算法和对旅行商(TSP)问题的研究,提出了基于能耗分级的非固定周期和固定周期两种小车充电策略。仿真结果表明,与传统的充电策略相比,两种新策略均能有效减少充电小车的移动总路径。

为探求提高超临界CO2萃取含油钻屑效率的最优方案,文章重点研究了萃取温度、萃取压力、萃取时间、挟带剂等关键参数对萃取效率的影响。根据CO2相态变化,设定超临界CO2萃取装置的温度、压力梯度变化,同时引入3种挟带剂,开展不同萃取参数的正交实验,采用红外分光光度法检测萃取后钻屑含油量。实验结果表明,稳压10MPa、恒温45℃,同时加入2%的非极性挟带剂石油醚,连续萃取2h后,钻屑含油量可降低至0.2%以下,且回收后的基础油相与白油成分接近,重复配置的油包水钻井液体系经150℃热滚16h后,检测流变、滤失等性能均未受影响。
