2Controlled synthesis of single cobalt atom catalysts via a facile one-pot pyrolysis for efficient oxygen reduction and hydrogen evolution reactions显示文摘Metal-nitrogen doped carbon catalysts(M-N/C) with abundantly accessible M-Nxsites, particularly single metal atom M-N/C(SAM-N/C), have been developed as a substitute for expensive Pt-based catalysts.These catalysts are used to increase the efficiency of otherwise sluggish oxygen reduction reactions(ORR) and hydrogen evolution reactions(HER). However, although the agglomerated metal nanoparticles are usually easy to form, they are very difficult to remove due to the protective surface-coating carbon layers, a factor that significantly hampers SAM-N/C fabrication. Herein, we report a one-step pyrolysis approach to successfully fabricate single cobalt atom Co-N/C(SACo-N/C) by using a Co2+-SCN-coordination compound as the metal precursor. Thanks to the decomposition of Co2+-SCN-compound at lower temperature than that of carbon layer deposition, Co-rich particles grow up to larger ones before carbon layers formation. Even though encapsulated by the carbon layers, it is difficult for the large Co-rich particle to be completely sealed. And thus, it makes the Co atoms possible to escape from incomplete carbon layer, to coordinate with nitrogen atoms, and to form SACo-N/C catalysts. This SACo-N/C exhibits excellent performances for both ORR(half-wave potential of 0.878 V) and HER(overpotential at 10 mA/cm2 of178 m V), and is thus a potential replacement for Pt-based catalysts. When SACo-N/C is integrated into a Zn-O2 battery, battery with high open-circuit voltage(1.536 V) has high peak power density(266 mW/cm2)and large gravimetric energy density(755 mA h/gZn) at current densities of 100 mA/cm2. Thus, we believe that this strategy may offer a new direction for the effective generation of SAM-N/C catalysts.Yao Wang Linhui Chen Zhanxin Mao Lishan Peng Rui Xiang Xianyi Tang Jianghai Deng Zidong Wei Qiang Liao 2019Science Bulletin2019,64,15:10
3Hierarchically porous nitrogen-doped carbon as cathode for lithium–sulfur batteries显示文摘Porous nitrogen-doped carbon is an especially promising material energy storage due to its excellent conductivity, stable physicochemical properties, easy processability, controllable porosity and low price.Herein, we reported a novel well-designed hierarchically porous nitrogen-doped carbon(HPNC) via a combination of salt template(ZnCl_2) and hard template(SiO_2) as sulfur host for lithium–sulfur batteries. The low-melting ZnCl_2 is boiled off and leaves behind micropores and small size mesopores during pyrolysis process, while the silica spheres are removed by acid leaching to generate interconnected 3D network of macropores. The HPNC-S electrode exhibits an initial specific capacity of 1355 mAh g^(–1) at 0.1 C(1 C = 1675 m Ah g^(–1)), a high-rate capability of 623 m Ah g^(–1) at 2 C, and a small decay of 0.13% per cycle over 300 cycles at 0.2 C. This excellent rate capability and remarkable long-term cyclability of the HPNC-S electrode are attributed to its hierarchical porous structures for confining the soluble lithium polysulfide as well as the nitrogen doping for high absorbability of lithium polysulfide.Rui Wu Siguo Chen Jianghai Deng Xun Huang Yujie Song Ruiyi Gan Xiaoju Wan Zidong Wei 2018Journal of Energy Chemistry2018,27,6:8
4Enhancing the stability and activity by anchoring Pt nanoparticles between the layers of etched montmorillonite for oxygen reduction reaction显示文摘Proton exchange membrane fuel cells(PEMFCs)are recognized as potential environmentally friendly power sources owing to their high energy conversion efficiency and low pollutant emissions[1–4].However,the insufficient electrocatalytic durability of Pt cathode catalysts remains one of the major obstacles for their wide applications[5–8].The Pt cathode catalyst is predominantlyWei Li Wei Ding Yao Nie Xueqiang Qi Guangping Wu Li Li Jianhua Liao Siguo Chen Zidong Wei 2016Science Bulletin2016,61,18:5
5Pinning controllability of autonomous Boolean control networks显示文摘Autonomous Boolean networks(ABNs), which are developed to model the Boolean networks(BNs)with regulatory delays, are well known for their advantages of characterizing the intrinsic evolution rules of biological systems such as the gene regulatory networks. As a special type of ABNs with binary inputs, the autonomous Boolean control networks(ABCNs) are introduced for designing and analyzing the therapeutic intervention strategies where the binary inputs represent whether a certain medicine is dominated or not. An important problem in the therapeutic intervention is to design a control sequence steering an ABCN from an undesirable location(implying a diseased state) to a desirable one(corresponding to a healthy state). Motivated by such background, this paper aims to investigate the reachability and controllability of ABCNs with pinning controllers. Several necessary and sufficient criteria are provided by resorting to the semi-tensor product techniques of matrices. Moreover, an effective pinning control algorithm is presented for steering an ABCN from any given states to the desired state in the shortest time period. Numerical examples are also presented to demonstrate the results obtained.Hongwei CHEN Jinling LIANG Zidong WANG 2016Science China(Information Sciences)2016,59,7:5
6Robust control for a class of nonlinear networked systems with stochastic communication delays via sliding mode conception显示文摘This paper deals with the robust control problem for a class of uncertain nonlinear networked systems with stochastic communication delays via sliding mode conception(SMC).A sequence of variables obeying Bernoulli distribution are employed to model the randomly occurring communication delays which could be different for different state variables.A discrete switching function that is different from those in the existing literature is first proposed.Then,expressed as the feasibility of a linear matrix inequality(LMI)with an equality constraint,sufficient conditions are derived in order to ensure the globally mean-square asymptotic stability of the system dynamics on the sliding surface.A discretetime SMC controller is then synthesized to guarantee the discrete-time sliding mode reaching condition with the specified sliding surface.Finally,a simulation example is given to show the effectiveness of the proposed method.Lifeng MA Zidong WANG Xuemin CHEN Zhi GUO 2010控制理论与应用(英文版)2010,8,1:2

11DSNNs:learning transfer from deep neural networks to spiking neural networks显示文摘Deep neural networks(DNNs)have drawn great attention as they perform the state-of-the-art results on many tasks.Compared to DNNs,spiking neural networks(SNNs),which are considered as the new generation of neural networks,fail to achieve comparable performance especially on tasks with large problem sizes.Many previous work tried to close the gap between DNNs and SNNs but used small networks on simple tasks.This work proposes a simple but effective way to construct deep spiking neural networks(DSNNs)by transferring the learned ability of DNNs to SNNs.DSNNs achieve comparable accuracy on large networks and complex datasets.张磊 Du Zidong Li Ling Chen Yunji 2020High Technology Letters2020,26,2:1

13Transcriptome-wide Dynamics of m^(6)A mRNA Methylation During Porcine Spermatogenesis显示文摘Spermatogenesis is a continual process that occurs in the testes,in which diploid spermatogonial stem cells(SSCs)differentiate and generate haploid spermatozoa.This highly efficient and intricate process is orchestrated at multiple levels.N^(6)-methyladenosine(m^(6)A),an epigenetic modification prevalent in mRNAs,is implicated in the transcriptional regulation during spermatogenesis.However,the dynamics of m^(6)A modification in non-rodent mammalian species remains unclear.Here,we systematically investigated the profile and role of m^(6)A during spermatogenesis in pigs.By analyzing the transcriptomic distribution of m^(6)A in spermatogonia,spermatocytes,and round spermatids,we identified a globally conserved m^(6)A pattern between porcine and murine genes with spermatogenic function.We found that m^(6)A was enriched in a group of genes that specifically encode the metabolic enzymes and regulators.In addition,transcriptomes in porcine male germ cells could be subjected to the m^(6)A modification.Our data show that m^(6)A plays the regulatory roles during spermatogenesis in pigs,which is similar to that in mice.Illustrations of this point are three genes(SETDB1,FOXO1,and FOXO3)that are crucial to the determination of the fate of SSCs.To the best of our knowledge,this study for the first time uncovers the expression profile and role of m^(6)A during spermatogenesis in large animals and provides insights into the intricate transcriptional regulation underlying the lifelong male fertility in non-rodent mammalian species.Zidong Liu Xiaoxu Chen Pengfei Zhang Fuyuan Li Lingkai Zhang Xueliang Li Tao Huang Yi Zheng Taiyong Yu Tao Zhang Wenxian Zeng Hongzhao Lu Yinghua Lv 2023Genomics, Proteomics & Bioinformatics2023,21,4:1

19Surfactant assisted solvothermal synthesis of LiFePO4 nanorods for lithium-ion batteries显示文摘Well-shaped and uniformly dispersed LiFePO_4 nanorods with a length of 400–500 nm and a diameter of about 100 nm, are obtained with participation of a proper amount of anion surfactant sodium dodecyl sulfonate(SDS) without any further heating as a post-treatment. The surfactant acts as a self-assembling supermolecular template, which stimulated the crystallization of LiFePO_4 and directed the nanoparticles growing into nanorods between bilayers of surfactant(BOS). LiFePO_4 nanorods with the reducing crystal size along the b axis shorten the diffusion distance of Li^+ extraction/insertion, and thus improve the electrochemical properties of LiFePO_4 nanorods. Such prepared LiFePO_4 nanorods exhibited excellent specific capacity and high rate capability with discharge capacity of 151 mAh/g, 122 mAh/g and 95 mAh/g at 0.1C, 1 C and 5 C, respectively. Such excellent performance of LiFePO_4 nanorods is supposed to be ascribed to the fast Li^+ diffusion velocity from reduced crystal size along the b axis and the well electrochemical conductivity. The structure, morphology and electrochemical performance of the samples were characterized by XRD, FE-SEM, HRTEM, charge/discharge tests, and EIS(electrochemical impedance spectra).Yuan Gao Ke Chen Hongmei Chen Xiaohua Hu Zihua Deng Zidong Wei 2017Journal of Energy Chemistry2017,26,3:1
