Dinuclear metal synergistic catalysis(DMSC)has been proved powerful in boosting CO_(2)reduction,while this has not been achieved in heterogeneous catalysts with long-range order *** this study,we,by introduction of metal catalytic centers into an indium-based metal-organic framework(MOF),obtained a series of isostructural In-MOFs,including three MOFs with mononuclear metal catalytic center(M-In),three MOFs with dinuclear homometallic catalytic centers(MM-In),and three MOFs with dinuclear heterometallic catalytic centers(MM’-In,M/M’=Co(II),Ni(II),Zn(II)).It was found that all these MOFs can serve as catalysts for photochemical CO_(2)reduction to *** with M-In,the catalytic activities of MM-In were obviously enhanced,and that of MM’-In was further significantly *** example,the CO yield of Co Zn-In reaches a record value of 12,700μmol g^(-1)h^(-1),which is 4.0,8.1,9.4,and 18.6-fold higher than that of Co Co-In,Zn Zn-In,Co-In,and Zn-In,***,the catalytic activities of Co Ni-In and Ni Zn-In also show different fold increase than those of corresponding dinuclear homometallic and mononuclear metallic *** results of control experiments and theoretical calculation reveal that the higher catalytic activities of MM-In over M-In can be ascribed to the DMSC effect,and the higher catalytic activity of MM’-In over MM-In can be ascribed to the strengthened DMSC *** work reveals the relationship between DMSC effect and bimetal centers in CO_(2)reduction,which provides new insights into the DMSC and paves a new way to design highly active catalysts for photochemical CO_(2)reduction.

The early Silurian conodonts are firstly described and illustrated from western Thailand. Samples were collected from the Kroeng Kravia Forest Park area for conodont and lithofacies analyses. An upper Telychian Lower Pterospathodus amorphognathoides amorphognathoides Subzone is recognized for the studied succession. Three lithofacies were identified from the carbonate succession, including stromatolite-thrombolite limestone, nodular limestone, and red limestone. Both analyses on lithofacies and conodont assemblages indicate a deeper marine depositional environment. The conodont fauna in the study area is similar to that from Baoshan of Yunnan Province and Langao of Shaanxi Province in West China and resembles that from similar depositional environments in Australia, Laurentia, and peri-Gondwana, suggesting good connections among these regions by ocean currents.

作者： Bo-Bo Gou wen-jie Shen Yuan-Jun Gao Qing Gu Shu-Li You New Cornerstone Science Laboratory State Key Laboratory of Organometallic Chemistry Shanghai Institute of Organic ChemistryChinese Academy of Sciences

Molecular chirality is a cornerstone of modern chemistry and it has a profound impact on biological activity, chemical reactivity and physical property. Developing asymmetric synthesis methods to efficiently and precisely produce chiral molecules remains a challenging issue in organic chemistry. In recent years, transition-metal-catalyzed enantioselective C–H activation has emerged as an efficient strategy for the rapid access to valuable chiral compounds from readily available feedstocks in an atom-and step-economic manner. Here we report a rhodium(III)-catalyzed C–H activation/annulation of ketones with alkynes. This method features mild conditions, wide substrate scope, and perfect atom economy, affording a series of chiral tertiary indenols in excellent yields and enantioselectivity(up to 98% yield and 99% ee). Combined experimental and computational studies revealed the turnover-limiting step of the reaction and the origins of enantioselectivity and regioselectivity.

Science China(Information Sciences) 2025年第2期68卷 393-394页

Silicon photonics has provided a platform for the convergency of photonic devices and electronic circuits, facilitating the development of optical telecommunications and optical interconnects on chip [1]. As the basic building block of optical communication systems, electro-optic tuning is expected to be more compact, high bandwidth, energy efficient, and allow for CMOS-compatible fabrication in the future [2]. Resonator-based electro-optic tuning has attracted more and more interest due to the small footprint, enhanced light-matter interactions and high energy efficiency. Compared with microring and microdisk resonators, photonic crystal nanobeam cavities(PCNBCs) realize higher quality factors, stronger light-matter interactions, ultrasmall mode volume and a much larger free spectral range(FSR) [3].

Autocyclic switching processes and architecture of lobes in river-dominated lacustrine deltas

Journal of Palaeogeography 2025年第1期14卷 126-140页

River-dominated lacustrine deltas typically consist of multiple lobes due to autogenic lobe switching that occurs over short time scales. However, the switching patterns of multiple lobes in these deltas remain poorly understood, and the architectural features attributed to lobe switching are also lacking. By integrating Delft3D simulations, flume experiments, and modern deposit analysis, we proposed that autogenic lobe switching follows a cyclic pattern. Autocyclicity begins with the formation of an offshore lobe and concludes after a series of longshore lobe growth events, marked by longshore avulsions occurring along the sides of offshore distributary *** avulsions follow a sequence that usually occurs earlier distally than proximally and subsequently occurs on one longshore side and then on the other side. Each lobe begins with rapid growth, which gradually slows and then stops once a channel avulsion is influenced by the backwater effect that triggers lobe switching. Three signals indicate lobe switching: a decrease in progradation rate, foreset slope steepening coupled with topset slope gentling, and the deposition of mud-dominated sediments. The number of autocyclic events never exceeds *** first two autocyclicities contribute to more than 55% of delta length and 70% of delta area. The lobes are separated by 1-6 stages of mud-dominated accretion beds that exhibit a downstream-inclined shape and convexup or lateral overlapping pattern. This study conducts a coupled growth-geometric assessment to establish an architectural pattern for river-dominated lacustrine deltas. This architectural pattern offers valuable insights into predicting sandy lobe distribution in river-dominated lacustrine delta reservoirs, and the architecture of muddy accretion beds aids in predicting the rule of oil-water movement and distribution of remaining oil.

Ship detection based on improved SDD algorithm

引用

Instrumentation 2025年

作者： Hong-cheng Chu Tian-hu Wang Qian-nian Miao Ze-ran Chen Rong Wang wen-jie Li Tao Huang School of Electrical Information Engineering Jiangsu University of Technology Changzhou High-tech Technology Innovation and Entrepreneurship Service Center Technical Development Department CRRC Nanjing Puzhen Rolling Stock Co. Ltd.

To address the issue of inadequate detection performance for small and mediumsized densely packed vessels in ship target detection, this paper proposes an improved Single Shot Multibox Detector(SSD) model to achieve more accurate detection. The algorithm redesigns the anchor boxes to fit the ship target detection dataset better and integrates the Squeeze-and-Excitation(SE) module into the Visual Geometry Group(VGG)network to enhance the channel features of the input feature maps. Additionally, the network's ability to perceive and represent important features is further enhanced by introducing the Convolutional Block Attention Module(CBAM), which is responsible for channel and spatial attention mechanisms. Finally, the feature pyramid module is employed to fuse six layers of features from the original network, thereby improving the SSD network's capability to detect small and occluded densely packed vessel targets. The experimental results show that the model's target recognition ability for fishing vessels improved from 58.07% to 65.87%; for patrol boats, the ability increased from 94.6% to 96.03%; and for inflatable boats, it rose from 72.08% to 74.93%. The overall mean Average Precision(mAP) also increased from the original model's 80.04% to 81.22%. Additionally, by clustering prior boxes, more suitable prior boxes for vessel detection were obtained, enhancing the model's perception capabilities for both large and small vessels.
