| 1 | Copper as a single metal atom based photo-,electro-,and photoelectrochemical catalyst decorated on carbon nitride surface for efficient CO_(2) reduction:A review显示文摘The processes of photocatalytic CO_(2) reduction(pCO_(2)R)and electrochemical CO_(2) reduction(ECO_(2)R)have attracted considerable interest owing to their high potential to address many environmental and energy-related issues.In this aspect,a single Cu atom decorated on a carbon nitride(CN)surface(Cu-CN)has gained increasing popularity because of its unique advantages,such as excellent atom utilization and ultrahigh catalytic activity.CN-particularly graphitic CN(g-C_(3)N_(4))-is a photo-and electrocatalyst and used as an important support material for single Cu atom-based catalysts.These key functions of Cu-CN-based catalysts can improve the catalytic performance and stability in the pCO_(2)R and ECO_(2)R during the application process.In this review,we focus on Cu as a single metal atom decorated on CN for efficient photoelectrochemical CO_(2) reduction(pECO_(2)R),where ECO_(2)R increases the electrocatalytic active area and promotes electron transfer,while pCO_(2)R enhances the surface redox reaction by efficiently using photogenerated charges and offering integral activity as well as an active interface between Cu and CN.Interactions of single Cu atom-based photo-,electro-,and photoelectrochemical catalysts with g-C_(3)N_(4) are discussed.Moreover,for a deeper understanding of the history of the development of pCO_(2)R and ECO_(2)R,the basics of CO_(2) reduction,including pCO_(2)R and ECO_(2)R over g-C_(3)N_(4),as well as the structural composition,characterization,unique design,and mechanism of a single atom site are reviewed in detail.Finally,some future prospects and key challenges are discussed. | Lulu Li Israr Masood ul Hasan Farwa Ruinan He Luwei Peng Nengneng Xu Nabeel Khan Niazi Jia-Nan Zhang Jinli Qiao | 2022 | Nano Research Energy2022，1，2： | 7 |

| 3 | Gravity Investigation in Area East of River Nile (Khartoum State)显示文摘The purpose of the study is to investigate the subsurface geology of the area. For quantitative interpretation of the resulting Bouguer anomalies, borehole data are explored. This is done along several profiles obtained from software program G.model version 2.2 No.175. This program is based on two dimensional mass distribution. The interpretation reveals two basinal features filling depressions in the basement complex named as Abu Harira basin and Kabbashi basin. They are structurally related to Khartoum basin. As a result, a geological/structural map of the area in east of the Nile is produced. The basinal features in the study area are considered as parts of the central Sudan (Khartoum basin) that had been subjected to several tectonic events that resulted in the formation of several fracture systems associated with block subsidence and formation of these basins. | Eldawi M G Farwa A G | 2003 | Journal of China University of Geosciences2003，14，2： | 1 |

| 5 | Sedimentary Basins in the Western White Nile, Sudan, as Indicated by a Gravity Survey显示文摘An academic geophysical research as a regional gravity survey was made during 1994 in the Western White Nile to infer the shallow crustal structures in the area. The result of the survey was compiled as a Bouguer anomaly map with a contour interval of 2 ×10 -5 m/s 2. It is found that the negative residual anomalies are related to the Upper Cretaceous sediments (Nubian Sandstone Formation) filling all depressions in the Basement complex surface while the positive residual anomalies are attributed to the relatively shallow or outcropping Basement rocks and the steep gravity gradients are resulting from the sharp contacts between the sedimentary infill and the Basement rocks. To define the geological structures in the area, 9 profiles were studied. For each of the profiles, measured and computed Bouguer gravity anomalies, crustal density model, subsurface geology evaluation were performed. A G model computer program was applied in the gravity modeling, which is based on the line integral method of gravity computation. A geological/structural map was proposed showing inferred sedimentary basins, faulting troughs and uplifted Basement block and tectonic trends. The basins are believed to be fault controlled which developed by extensional tectonics (pull apart mechanism). As for the mechanism and cause of faulting, the area is considered as a part of the Central Sudan rift system which had been subjected to several tectonic events since Early Cambrian to Tertiary times which resulted in the formation of several fracture systems associated with block subsidence, rifting and basin formation. | Mohammed I A Wang Jiaying Liu Tianyou Department of Geophysics, China University of Geosciences, Wuhan 430074 Farwa A G Department of Geology, Faculty of Science, University of Khartoum, Sudan | 2002 | Journal of China University of Geosciences2002，13，3： | 0 |
