Detrital mineral characteristics and material source identification in surface sediments of Yalu River estuary and adjacent waters

Geographical Research (2010)

Cheng Yan Yue Liu Fuxiang Li Jingwei Liu Liang Zhang

The Yalu River is the boundary river between China and Democratic People's Republic of Korea.The characteristics of detrital minerals in surface sediments in the Yalu River estuary and its adjacent shallow seas were analyzed in this paper.Through discussing on the compositions,distribution and longitudinal variation of detrital minerals in surface sediments,interpreting the sedimentary environment of detrital minerals and the difference of indicative mineral and characteristic index as well as their trace significance,the results indicated that the surface sediments in the Yalu River estuary and its adjacent shallow seas probably came from different material source zones.For the surface sediments in Middle-river-way and the lower reaches of the Yalu River,their longitudinal variation of main detrital minerals is successive.They are similar to the sediment characteristics in the Aihe River in the lower reaches of the Yalu River in material source zones index,stable coefficient and ATi,which indicates that the sediment process in Middle-river-way and modern rivers have a close relationship.Although West-river-way and Middle-river-way are adjacent,the sediments in West-river-way and Shuifeng Reservoir are similar more or less,which indicates that West-river-way is the key river course,remaining the sediment characteristics before the reservoir was built in 1941.That the sediments in West-river-way most came from the shallow seas offers the obvious evidence that the sediments in shallow seas moved to land areas.The characteristic minerals and other indexes in shallow ford of Liaodong are between those of Middle-river-way and West-river-way,which indicates that its material resource most came from the Yalu River,and less came from shallow seas.The degree of influence from shallow seas needs a further study.

Molecularly Designing a Passivation ETL to Suppress EQE Roll-off of PeLEDs

ACS Energy Letters (2023)

Qungui Wang Yongjian Chen Cheng Yan Xiankan Zeng Xuehai Fu

Efficiently suppressing the external quantum efficiency (EQE) roll-off of perovskite light-emitting diodes (PeLEDs) urgently requires designing passivation electron transporting layers (ETLs) for intrinsically passivating perovskite surface defects toward next-generation illumination and display. Here, we molecularly designed the inherent passivation ETL B3PyPPM with a strong nucleophilic core-group to effectively passivate perovskite surface defects. Compared with ETL B3PyMPM, the B3PyPPM can theoretically form a tighter interaction with the perovskite surface and transfer more electrons to better passivate surface Pb2+ vacancies, leading to superior suppression of EQE roll-off in PeLEDs by reducing the trap-assisted nonradiative recombination. Experimentally, the B3PyPPM-based PeLED exhibits a higher EQE of 18.04%, greater luminance of 4.15 times, and a longer T50 of 5.38 times than B3PyMPM-based PeLEDs, evidently proving the superior EQE roll-off suppression of the stronger nucleophilic core-group-based ETL. Therefore, this work provides important guidance for rationally designing multifunctional ETLs to achieve high-performance and long-term stability in PeLEDs.

MoS₂/TiO₂ Edge‐On Heterostructure for Efficient Photocatalytic Hydrogen Evolution

Advanced Energy Materials (2016)

Haiyong He Junhao Lin Wei Fu Xingli Wang Hong Wang

Via edge engineering, a facile two-step method is demonstrated that produces solid edge-on junctions between TiO2 and few-layered MoS2 in large scale. MoS2/TiO2 edge-on heterostructures result in high conductive MoS2/TiO2 interfaces and optimized electron transport pathways that facilitate the electron–hole pair separation, leading to an efficient solar water splitting.

Characterization of Aerobic Denitrifying Bacterium Pseudomonas mendocina Strain GL6 and Its Potential Application in Wastewater Treatment Plant Effluent

International Journal of Environmental Research and Public Health (2019)

Wen Zhang Cheng Yan Jianing Shen Ruping Wei Yan Gao

To remove nitrate in wastewater treatment plant effluent, an aerobic denitrifier was newly isolated from the surface flow constructed wetland and identified as Pseudomonas mendocina strain GL6. It exhibited efficient aerobic denitrification ability, with the nitrate removal rate of 6.61 mg (N)·L-1·h-1. Sequence amplification indicated that the denitrification genes napA, nirK, norB, and nosZ were present in strain GL6. Nitrogen balance analysis revealed that approximately 74.5% of the initial nitrogen was removed as gas products. In addition, the response surface methodology experiments showed that the maximum removal of total nitrogen occurred at pH 7.76, C/N ratio of 11.2, temperature of 27.8 °C, and with shaking at 133 rpm. Furthermore, under the optimized cultivation condition, strain GL6 was added into wastewater treatment plant effluent and the removal rates of nitrate nitrogen and total nitrogen reached 95.6% and 73.6%, respectively. Thus, P. mendocina strain GL6 has high denitrification potential for deep improvement of effluent quality.
