Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.

Surface analysis of tablets with and without coating film for common cold based on laser-induced breakdown spectroscopy

Optoelectronics Letters 2025年

Medications for common cold are used routinely in daily life， and most of these are compounded to be more effective for people suffering from common cold. The composition and quality of the coating， a common component of tablets， have been of great concern. In this paper， laser-induced breakdown spectroscopy (LIBS)， with advantages of rapid， real-time， and in-situ analysis， was used for surface analysis of tablets with and without coating film for common cold. Firstly， the spectra of compound paracetamol and amantadine hydrochloride tablets (CPAHT) and compound diclofenac sodium and chlorphenamine maleate tablets (CDSCMT)， without and with coating film， respectively， were analyzed. Secondly， two kinds of tablets were investigated in-situ at depth to analyze the changes of atomic and molecular spectral line intensities under different number of laser pulses and verified using LIBS imaging method. Finally， the Ca and Ti elements in CDSCMT were analyzed by calibration free LIBS (CF-LIBS) to further verify the elemental content differences at different depth in the tablets with coating film. These results indicate that the LIBS technology can be used in fast， in-situ， depth， and multi-element detection for cold medication tablets.

Pyrite Geochemistry and S-Hg Isotopes Reveal the Ore Genesis of the Hydrothermal Vein-type Cuiluan Ag-Pb-Zn Deposit in NE China

引用

Journal of Earth Science 2025年

作者： Lidong Zhang Changzhou Deng yao Tang Xinran Ni Bizheng Yang Shanshan Liang Weipeng Liu Jishuang Ding Xiaohui Zeng Heilongjiang Institute of Natural Resources Survey State Key Laboratory of Ore Deposit Geochemistry， Institute of Geochemistry， Chinese Academy of Sciences College of Earth and Planetary Sciences， Chengdu University of Technology

The Xing'an-Mongolian orogenic belt is an important Ag-Pb-Zn metallogenic province in China. The study on the genesis of the newly discovered Cuiluan hydrothermal vein-type Ag-Pb-Zn deposit located in the Lesser Xing'an Range， within the eastern of Xing'an-Mongolian orogenic belt， is pivotal in understanding the metallogenic mechanism and regularity of Ag-Pb-Zn deposits in this region. This study utilizes pyrite trace elements and sulfur isotopic geochemistry， and mercury isotope of rocks and ores to constrain the genesis of the Cuiluan deposit. Pyrite geochemical data show that Ag exists in the form of galena inclusions (Ag++(Bi3+， Sb3+) ? Pb2+) in the polymetallic sulfide stage， and independent Ag-bearing minerals （matildite and gustavite） precipitate during the main mineralization stage. The small varied δ34S values （3.24‰ - 4.94‰） of pyrites from four hydrothermal stages are within the range of magmatic S isotopes， indicating that the ore-forming fluid of the Cuiluan deposit mainly originated from the magma. The Δ199Hg values of the ores are close to 0‰， which are consistent with the Δ199Hg values of mantle， further indicating that the ore-forming materials came from the lithospheric mantle. Combined with the regional tectonic evolution， we conclude that the plate subduction of Paleo-oceans in NE China triggered the partial melting of metasomatized mantle. The mantle-derived magma rose along the deep fractures and evolved ore-forming fluids， and finally caused the formation of Cuiluan quartz vein-type Ag-Pb-Zn deposit in the shallow crust. Accompany with previous documents， we infer that the fractures in the large-scale “Granite Sea” in the Lesser Xing'an Range may have significant potential for vein-type Ag-Pb-Zn exploration.

New hybrid inertial CQ projection algorithms with line-search process for the split feasibility problem

引用

Applied Mathematics(A Journal of Chinese Universities) 2023年第1期38卷 144-158页

作者： DANG Ya-zheng WANG long YANG yao-heng School of Management University of Shanghai for Science and TechnologyShanghai 200093China

In this paper, we propose two hybrid inertial CQ projection algorithms with linesearch process for the split feasibility problem. Based on the hybrid CQ projection algorithm, we firstly add the inertial term into the iteration to accelerate the convergence of the algorithm, and adopt flexible rules for selecting the stepsize and the shrinking projection region, which makes an optimal stepsize available at each iteration. The shrinking projection region is the intersection of three sets, which are the set C and two hyperplanes. Furthermore, we modify the Armijo-type line-search step in the presented algorithm to get a new *** algorithms are shown to be convergent under certain mild assumptions. Besides, numerical examples are given to show that the proposed algorithms have better performance than the general CQ algorithm.

Enhancement in Magnetorheological Effect of Magnetorheological Elastomers by Surface Modification of Iron Particles

引用

Chinese Journal of Chemical Physics 2008年第1期21卷 87-92页

作者： Wan-quan jiang Jing-jing yao Xing-long Gong Lin Chen Department of Chemistry University of Science and Technology of China Hefei 230026 China CA5 Key Laboratory of Mechanical Behavior and Design of Materials Department of Mechanics andMechanical Engineering University of Science and Technology of China Hefei 230027 China

In order to obtain magnetorheological （MR） elastomers with high magnetorheological effect, a family of anisotropic rubber-based MR elastomers was developed using a new form of chemical modification. Three different kinds of surfactants, i.e. anionic, nonionic and compound surfactants, were employed separately to modify iron particles. The MR effect was evaluated by measuring the dynamic shear modulus of MR elastomer with a magneto-combined dynamic mechanical analyzer. Results show that the relative MR effect can be up to 188% when the iron particles are modified with 15% Span 80. Besides the surface activity of Span 80, however, such high modifying effect is partly due to the plasticizing effect of Span 80. Compared with the single surfactant, the superior surface activity of compound surfactant makes the relative MR effect reach 77% at a low content of 0.4%. Scanning electron microscope observation shows that the modification of compound surfactant results in perfect compatibility between particles and rubber matrix and special self-assembled structure of particles. Such special structure has been proved beneficial to the improvement of the relative MR effect.

Power Optimization in Cell-Free Massive MIMO with Non-ideal Hardware Transceiver

引用

Chinese Journal of Electronics 2020年第1期29卷 190-198页

作者： ZHANG yao CAO Haotong ZHOU Meng LI long YANG longxiang Wireless Communications Key Laboratory of jiangsu Province Nanjing University of Posts and Telecommunications Department of Information Technology Party School of the Communist Party of China Shandong Provincial Committee

A downlink cell-free massive Multipleinput multiple-output(mMIMO) system is explored. To investigate the impact of hardware distortion on downlink cell-free mMIMO, this paper recalls a well-established model of hardware impairment and derives a new closedform downlink per-user Spectral efficiency(SE) expression for distributed conjugate beamforming precoding. Based on this trackable expression, two power control algorithms,namely max-total-SE and mixed Quality-of-service(QoS)algorithms, are proposed. Numerical results indicate that the downlink per-user SE is primarily limited by the hardware quality of the receiver, especially when the user corresponds to the receiver. In addition, the proposed max-total-SE algorithm has a fast convergence rate and can significantly improve the total SE compared to the Equal power control(EPC) scheme. What’s more, our mixed QoS algorithm also performs well in many respects.
