1PEMFC Fractional-order Subspace Identification Model显示文摘A proton exchange membrane fuel cell(PEMFC)is a new type of hydrogen fuel cell that plays an indispensable role in an energy network.However,the multivariable and fractional-order characteristics of PEMFC make it difficult to establish a practical model.Herein,a fractional-order subspace identification model based on the adaptive monarch butterfly optimization algorithm with opposition-based learning(ALMBO)algorithm is proposed for PEMFC.Introducing the fractional-order theory into the subspace identification method by adopting a Poisson filter for with input and output data,a weight matrix is proposed to improve the identification accuracy.Additionally,the ALMBO algorithm is employed to optimize the parameters of the Poisson filter and fractional order,which introduces an opposition-based learning strategy into the migration operator and incorporates adaptive weights to improve the optimization accuracy and prevent falling into a locally optimal solution.Finally,the PEMFC fractional-order subspace identification model is established,which can accurately describe the dynamic process of PEMFC.Sun Chengshuo Qi Zhidong Qin Hao Shan Liang 2022China Petroleum Processing & Petrochemical Technology2022,24,3:2
2Control Approaches to Soil Pollution from Heavy Metals显示文摘With the continuous development of human society and economy and the continuous progress of industrial technology,more and more pollutants are discharged into the natural environment,and soil environment is also affected at the same time. Among pollutants leading to soil pollution,heavy metals have resulted in most serious soil pollution. Here,many control and restoration approaches to soil pollution from heavy metals are proposed,and characteristics and applicable conditions of various methods are compared,so as to provide theoretical references for the control and restoration of soil pollution from heavy metals in future.Feng Lei Fang Jiangping Zhang Chengshuo Hu Tengfei 2015Meteorological and Environmental Research2015,6,2:2
3Study on Growth,Serum Biochemical and Antioxidant Enzyme Indices of Juvenile Siganus guttatus Fed with Enteromorpha prolifra and Artificial Feed显示文摘In order to provide reference for using Siganus guttatus to control overgrowth of Enteromorpha prolifra,the growth,serum biochemical and antioxidant enzyme indices of juvenile S.guttatus respectively fed with E.prolifra and artificial feed were studied.One hundred and eighty individuals were cultivated for 90 days in six 2.5 m × 1.5 m × 1.5 m cages (30 ind.per cage) which mesh size were 0.5 mm.The experimental animals were divided into two dietary groups (three cages for each group) that were fed with E.prolifra and artificial feed respectively.During the culture period,temperatures ranged from 23.0 to 26.5℃,p H was between 7.8 and 8.2,dissolved oxygen was more than 5.0 mg/L.The weight gain rate,specific growth rate,relative growth rate,hepato-somatic index of juvenile S.guttatus fed with E.prolifra were significantly lowe than that fed with artificial feed (P<0.05).The total protein (TP),urea nitrogen (UN)and alkaline phosphatase (AKP) of juvenile S.guttatus fed with E.Prolifra were significantly higher than that fed with artificial feed (P<0.05),while glutamic oxalacetic transaminase (AST/GOT) and glutamic-pyruvic transaminase (ALT/GPT) of juvenile S.guttatus fed with E.prolifra were significantly lower than that fed with artificial feed (P<0.05).SOD,GPX and anti-superoxide anion radical activity in liver,kidney,gill and muscle of juvenile S.guttatus fed with E.prolifra were higher than that fed with artificial feed,and these antioxidant enzyme activities in kidney of juvenile S.guttatus fed with E.prolifra was significantly higher than that fed with artificial feed (P<0.05),while CAT and hydroxyl radical-inhibiting activity in liver of juvenile S.guttatus fed with artificial feed were significantly higher than that fed with E.prolifra (P<0.05).Juvenile S.guttatus fed with E.prolifra showed poor growth performance but better antioxidant defense system.S.guttatus is easily raised and has stronger ability of digestion and absorption of E.Prolifra.The technique that uses S.guttatus to control E.prolifra deserves deeply study.Song Chao Hu Chengshuo Zhang Longzhen Zhao Feng Huang Xiaorong Wang Yu Liu Jianyi 2016Animal Husbandry and Feed Science2016,8,5:2

8Tunable Multicolor Circularly Polarized Luminescence via Co-assembly of One Chiral Electron Acceptor with Various Donors显示文摘Chiroptical materials with multicolor and signinvertible circularly polarized luminescence(CPL)are important for advanced optical devices and display technologies.Here,a general strategy is developed to generate CPL with highly tunable emission bands and handedness through charge-transfer(CT)complexation and co-assembly of one chiral non-emissive tetranitrofluorene-based acceptor with various achiral purple to blue emissive donors.The resulting assemblies exhibit intense CPL with a rich array of colors(519-668 nm)and prominent dissymmetry factors(|glum|)in the range of 10^(-3)-10^(-2).Notably,the CPL sign can be readily inverted by slightly changing the molecular structure of achiral donors.Single-crystal analysis reveals that the donor and acceptor molecules are alternately and asymmetrically packed in a lamellar fashion through CT interactions,leading to efficient transfer of chirality.Furthermore,the refined packing is mediated by the intensity and manner of CT interactions,rendering an inversion of chirality.The chiral co-assembly not only occurs for planar achiral donor molecules,but is also accessible to nonplanar conjugated molecules such as[4]helicene derivatives.Thus,the CPL feature of the resulting products can be easily and broadly manipulated,aiming at advanced chiroptical systems.Fang Wang Chengshuo Shen Fuwei Gan Guoli Zhang Huibin Qiu 2023CCS Chemistry2023,5,7:0
9Tunable construction of transition metal-coordinated helicene cages显示文摘We report a facile and tailored method to prepare globally twisted chiral molecular cages through tunable coordination of bis-bipyridine-terminated helicene ligands to a series of transition metals including Fe(Ⅱ), Co(Ⅱ), Ni(Ⅱ) and Zn(Ⅱ). This system shows an efficient remote transfer of stereogenecity from the helicene core to the bipyridine-metal coordination sites and subsequently the entire cages. While the Fe(Ⅱ), Co(Ⅱ) and Ni(Ⅱ)-derived M_(2)L_(3)(M for metal and L for ligand) cages exhibit quasi-reversible redox features, the Zn(Ⅱ) analogues reveal prominent yellow circularly polarized luminescence. Interestingly,with the addition of Na_(2)SO_(4), the Zn_(2)L_(3)cages reassemble into sextuple-stranded Zn_(6)L_(6)(SO_(4))_(4)cages in which three Zn_(2)L_(2) units are bound together by four sulfates and further coalesced by offset inter-ligandπ-π interactions.Yongle Ding Chengshuo Shen Fuwei Gan Jinghao Wang Guoli Zhang Lingling Li Mouhai Shu Bangshang Zhu Jeanne Crassous Huibin Qiu 2021Chinese Chemical Letters2021,32,12:0
10Expert consensus on odontogenic maxillary sinusitis multi-disciplinary treatment显示文摘Odontogenic maxillary sinusitis (OMS) is a subtype of maxillary sinusitis (MS). It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion. Due to the lack of unique clinical features, OMS is difficult to distinguish from other types of rhinosinusitis. Besides, the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis. Its current diagnosis and treatment are thus facing great difficulties. The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS. However, this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality. Based on systematically reviewed literature and practical experiences of expert members, our consensus focuses on characteristics, symptoms, classification and diagnosis of OMS, and further put forward multidisciplinary treatment decisions for OMS, as well as the common treatment complications and relative managements. This consensus aims to increase attention to OMS, and optimize the clinical diagnosis and decision-making of OMS, which finally provides evidence-based options for OMS clinical management.Jiang Lin Chengshuo Wang Xiangdong Wang Faming Chen Wei Zhang Hongchen Sun Fuhua Yan Yaping Pan Dongdong Zhu Qintai Yang Shaohua Ge Yao Sun Kuiji Wang Yuan Zhang Mu Xian Ming Zheng Anchun Mo Xin Xu Hanguo Wang Xuedong Zhou Luo Zhang 2024International Journal of Oral Science2024,16,1:0

12Helical Conformation Tunability via Hydrogen Bonding in Supramolecular Frameworks显示文摘Hydrogen-bonded molecules and their dynamics are significantly important in chemistry and biology due to their widespread functionality.Besides their natural abundance and diversity,applications of molecules with dynamic conformations in artificial networks allow information storage and molecular motor design on the nanometer scale.Here,we report hydrogen-bonded molecular networks with tunable helical conformation on metal surfaces.The dynamics of helical conformation in two-dimensional hydrogenbond networks are triggered and resolved by scanning probe microscopy at the single-molecule level.In combinationwith theoretical calculations,the surfacespecific hydrogen bonds are identified as the origin of the dynamic helical conformation.Our results provide a distinctive access to molecular architecture with tunable helical conformation driven by hydrogenbond interaction on surfaces.Zhijie Xue Fuwei Gan Hong Liu Chengshuo Shen Huibin Qiu Bo Yang Ping Yu 2022CCS Chemistry2022,4,4:0
13PEMFC Identification Based on a Fractional-Order Hammerstein State-Space Model with ADE-BH Optimization显示文摘Considering the fractional-order and nonlinear characteristics of proton exchange membrane fuel cells(PEMFC),a fractional-order subspace identification method based on the ADE-BH optimization algorithm is proposed to establish a fractional-order Hammerstein state-space model of PEMFCs.Herein,a Hammerstein model is constructed by connecting a linear module and a nonlinear module in series to precisely depict the nonlinear property of the PEMFC.During the modeling process,fractional-order theory is combined with subspace identification,and a Poisson filter is adopted to enable multi-order derivability of the data.A variable memory method is introduced to reduce computation time without losing precision.Additionally,to improve the optimization accuracy and avoid obtaining locally optimum solutions,a novel ADEBH algorithm is employed to optimize the unknown parameters in the identification method.In this algorithm,the Euclidean distance serves as the theoretical basis for updating the target vector in the absorption-generation operation of the black hole(BH)algorithm.Finally,simulations demonstrate that the proposed model has small output error and high accuracy,indicating that the model can accurately describe the electrical characteristics of the PEMFC process.Qin Hao Qi Zhidong Ye Weiqin Sun Chengshuo 2023China Petroleum Processing & Petrochemical Technology2023,25,2:0
