Dear editor,Among multiple levels of power and energy scheduling, day-ahead unit commitment (UC) has long been a challenging task for power system operators owing to the strong constrained, mixedinteger, and high-dimensional characteristics. The objective of UC is to minimize the fossil fuel cost in thermal power generation by determining the on–off status and power generation output while maintaining physical constraints, such as the demand

乍得Bongor盆地储层岩性复杂,非均质性强,不同岩性之间孔隙度、渗透率差异较大,直接应用测井资料评价储层渗透率的精度较低。为提高乍得Bongor盆地储层渗透率评价精度,首先以取心井段岩性识别为基础,结合测井响应特征,通过曲线重构,构建岩性指示、孔隙度指示曲线;其次应用构建的指示曲线,建立研究区的岩性识别标准;最后根据不同岩性的孔隙度、渗透率实验资料建立渗透率计算模型。实际应用表明,按不同岩性建立的储层渗透率计算模型其计算结果的精度与通用模型比显著提高。该方法为乍得Bongor盆地复杂砂砾岩储层渗透率评价提供了有效手段,也可应用于其他区块的渗透率计算。

Two kinds of Ru(Ⅱ)-bipyridine complexes, cis-di(thiocyanate)bis(2,2′-bipyridyl-4,4′-dicarboxylate) ruthenium(Ⅱ) and cis-di(thiocyanate)bis(2,2′-bipyridyl-3,3′-dicarboxylate) ruthenium(Ⅱ), were utilized as the sensitizers to the nanocrystalline TiO-2 film electrodes. Study shows that the two dyes have quite different sensitization properties due to the strong steric effect of carboxyl groups. In addition, the pretreatment to nanocrystalline TiO-2 film electrodes with TiCl-4 was investigated, which is an effective way to improve the photoelectric conversion performances of sensitized TiO-2 electrodes.

A novel parallel hybrid electrical urban bus （PHEUB） configuration consisting of an extra one-way clutch and an automatic mechanical transmission （AMT） is taken as the study subject. An energy management strategy combining a logic threshold approach and an instantaneous optimization algorithm is proposed for the investigated PHEUB. The objective of the energy management strategy is to achieve acceptable vehicle performance and drivability requirements while simultaneously maximizing the engine fuel consumption and maintaining the battery state of charge in its operation range at all times. Under the environment of Matlab/Simulink, a computer simulation model for the PHEUB is constructed by using the model building method combining theoretical analysis and bench test data. Simulation and experiment results for China Typical Bus Driving Schedule at Urban District （CTBDS_UD） are obtained, and the results indicate that the proposed control strategy not only controls the hybrid system efficiently but also improves the fuel economy significantly.

Transition metal oxide micro-/nanostructures demonstrate high potential applications in energy storage devices. Here, we report a facile synthesis of highly homogeneous oxide composites with porous structure via a coordination polymer precursor, which was prepared with the assistance of tartaric *** typical product, Fe-Mn-O composite was demonstrated here. The obtained Fe-Mn-O product was systemically characterized by X-ray powder diffraction, scanning electron microscopy, transmission electron microscopy, elemental mapping analysis, and X-ray photoelectron spectroscopy. It was demonstrated that the Fe-Mn-O nanocomposite shows interconnected porous structure, in which iron,manganese, and oxygen are uniformly distributed. In addition, the Fe-Mn-O nanocomposite was then fabricated as capacitor electrodes. Operating in an aqueous neutral solution, the Fe-Mn-O composite electrodes showed an wide working potential window from 0.2 to 1.0 V(vs. SCE), and a specific capacitance of 86.7 Fg-1or 0.4 Fcm-2at a constant current density of 1 Ag-1with good cycle life. This study offers a new precursor approach to prepare porous metal oxide composites, which would be applied in energy-storage/conversion devices, catalysts, sensors, and so on.

Controllable regulation of the reconstruction process for the pre-catalysts towards oxygen evolution remains as a great challenge. In this study, we report a bi-ligand strategy to facilitate the structural transformation of coordination compounds to metal oxyhydroxides during oxygen evolution with enhanced activity. A coordination compound consisting of 1,1′-ferrocene acid (Fc) and Ni2+ was synthesized, in which terephthalic acid was introduced. The second ligand of terephthalic acid facilitates the reconstruction process, inducing an enhanced catalytic activity. In 1 mol·L−1 KOH aqueous solution, the optimized catalyst can drive a current density of 10 mA·cm–2 under a lower overpotential of 220 mV. Using this catalyst, zinc-air batteries can be prepared. The obtained zinc-air battery presents a large specific capacity of 718 mA·h·g−1 with excellent cycling stability for over 100 h far exceeding that of Pt/C+RuO2 battery fabricated with commercial catalysts. The excellent performance and low cost of this catalyst will open up broad prospects for the development of advanced systems for water electrolysis and zinc air batteries. © 2024 The Chemical Industry and Engineering Society of China, and Chemical Industry Press Co., Ltd

为探讨马铃薯节水灌溉有效模式,研究了沟灌、滴灌、喷灌等不同灌溉方式及灌水量对马铃薯生长发育的影响。结果表明,中水量和高水量喷灌的产量和商品率最高,滴灌节水效果最好,隔行膜下沟灌、交替隔行沟灌虽与常规沟灌相比有一定的节水效果,但马铃薯商品性和产量明显下降。总体比较,在中原二季作地区,喷灌在保证马铃薯高产、高商品率的情况下,还能达到明显的节水效果,是较理想的高效灌溉模式。
