A method for multi-view surface defect detection of Si₃N₄ ceramic bearing balls integrating features enhanced by the Gabor salient domain

Measurement Science and Technology (2024)

Xinran Li Lei Chen Shuai Liu Meng Shao Ronghua Hu

Abstract Si 3 N 4 ceramic bearing balls exhibit wear, pits, scratches, and delamination defects on the surface during manufacturing processes. Current Si 3 N 4 ceramic ball detection methods mainly focus on a single view input, which leads to insufficient fusion of boundary, color, and shape features, consequently resulting in a low detection accuracy. In this research, propose multi-view surface defect detection of Si 3 N 4 ceramic bearing balls integrating features enhanced by the Gabor salient domain (GSMF). Firstly, color, shape, and boundary information of defects are extracted from different angles, distances, and GSMF enhancement views. Secondly, by designing a salient domain enhancement module, GSMF enhancement boundary features are extracted, addressing the feature loss problem that results in scarce border information during decoding. By improving the co-attention of multi-view to prevent memory loss caused by long-distance transmission, more feature information is preserved. Finally, the accuracy of the detection method is validated through experimental tests.

Metal–Organic Frameworks as Metal Ion Precursors for the Synthesis of Nanocomposites for Lithium‐Ion Batteries

Angewandte Chemie International Edition (2019)

Hongfeng Li Peng Wu Yawen Xiao Meng Shao Yu Shen

Metal-organic frameworks (MOFs) are promising materials with fascinating properties. Their widespread applications are sometimes hindered by the intrinsic instability of frameworks. However, this instability of MOFs can also be exploited for useful purposes. Herein, we report the use of MOFs as metal ion precursors for constructing functional nanocomposites by utilizing the instability of MOFs. The heterogeneous growth process of nanostructures on substrates involves the release of metal ions, nucleation on substrates, and formation of a covering structure. Specifically, the synthesized CoS with carbon nanotubes as substrates display enhanced performance in a lithium-ion battery. Such strategy not only presents a new way for exploiting the instability of MOFs but also supplies a prospect for designing versatile functional nanocomposites.

Hollow Ni–CoSe₂ Embedded in Nitrogen-Doped Carbon Nanocomposites Derived from Metal–Organic Frameworks for High-Rate Anodes

ACS Applied Materials & Interfaces (2018)

Liu Wan Meng Shao Weiqiang Zhou Bo Yuan Cong Gao

Developing high-rate anode materials with large capacity for lithium ion batteries (LIBs) is quite necessary for the booming electric vehicles industry. The utilization of stable and conductive hollow structures for electrode composite materials could make the desired performances possible in the future. Thus, in this study, a hollow structured Ni-CoSe2 embedded in N-doped amorphous carbon nanocomposite (Ni-CoSe2@NC) has been successfully synthesized with metal-organic frameworks (MOFs) as precursors. Such strategy integrates both the merits of the multicomponents and the hollow structure; the latter could facilitate both mass and charge transport, and the former (the N-doped carbon) could not only offer plenty of surface defects, improving the surface capacitive contributions, but also stabilize the electrode structure during the charge/discharge processes. As a result, the metal selenide composite delivers outstanding high-rate properties with good stability as the anode for LIBs. The structure and components design could also be extended to other anode composites in the future.

Multiple Active Sites of Carbon for High‐Rate Surface‐Capacitive Sodium‐Ion Storage

Angewandte Chemie (2019)

Guang Wang Meng Shao Huarui Ding Ying Qi Jiabiao Lian

Abstract Although sodium ion batteries (SIBs) possess many beneficial features, their rate performance, cycling stability, and safety need improvement for commercial applications. Based on the mechanisms of the sodium ions storage in carbon materials, herein we present a multiple active sites decorated amorphous carbon (MAC) with rich structural defects and heteroatom doping as an anode material for SIBs. The full utilization of fast bonding–debonding processes between the active sites and sodium ions could bring a capacitive strategy to achieve superior sodium storage properties. Consequently, after materials characterization and electrochemical evaluation, the as‐prepared electrode could deliver high rate and long‐life performance. This active‐site‐related design could be extended to other types of electrode materials, thereby contributing to future practical SIB applications.

Metal-Organic Framework Wears a Protective Cover for Improved Stability

Chemistry - A European Journal (2017)

Tao Zhang Binghua Zou Meng Shao Xinyi Chen Weina Zhang

Metal-organic frameworks (MOFs) with an ordered channel and porosity show great promise for a myriad of purposes. Unfortunately, the coordination bond of metal ions and organic ligands easily weakens in unfavorable environments, which poses a key problem in expanding the application of MOFs. Herein, we report a general and efficient strategy to enhance the stability and preserve the porosity of MOFs by coating them with reduced graphene oxide (rGO). The prepared hybrid material consisted of MOFs and rGO, as the core and the protective shell, respectively. It is worth noting that the obtained MOFs@rGO composite material maintained a well-defined crystal structure and showed good catalytic activity as well as enhanced stability. Notably, this novel and general method of coating MOFs with a thin protective rGO shell will broaden the application fields of MOFs and open up a new avenue for the research of MOFs.

SnSe₂ Nanoparticles Chemically Embedded in a Carbon Shell for High-Rate Sodium-Ion Storage

ACS Applied Materials & Interfaces (2019)

Fen Zhang Yu Shen Meng Shao Yongcai Zhang Bing Zheng

The development of advanced anode materials is crucial to enhance the performance of sodium-ion batteries (SIBs). In this study, SnSe2 nanoparticles chemically embedded in a carbon shell (SnSe2@C) were fabricated from Sn–organic frameworks and evaluated as an anode material for SIBs. The structural characterization demonstrated that there existed C–Sn chemical bonds between the SnSe2 nanoparticles and carbon shell, which could strongly anchor SnSe2 nanoparticles to the carbon shell. Such a structure can not only facilitate charge transfer but also ensure the structural stability of the SnSe2@C electrode. In addition, the carbon shell also helped in the dispersion of SnSe2 nanoparticles, thus offering more redox-active sites for Na+ storage. The as-prepared SnSe2@C nanocomposite could deliver good cycling stability and a superior rate capability of 324 mA h g–1 at 2 A g–1 for SIBs.
