| 1 | An Adaptive Tag Anti-Collision Protocol in RFID Wireless Systems显示文摘A novel anti-collision algorithm in RFID wireless network is proposed.As it is put forward on the basis of collision tree(CT)and improved collision tree(lCT) anti-collision protocols,we call it adaptive collision tree protocol(ACT).The main novelty of this paper is that the AD strategy is introduced and used in ACT to decrease collisions and improve the tag system throughput.AD strategy means that query strings will divide into two or four branches adaptively according to the label quantity.This scheme can decrease both depth of query and collision timeslots,and avoid producing too much idle timeslots at the same time.Both theoretical analysis and simulation results indicate that the novel proposed anticollision protocol ACT outperforms the previous CT and ICT protocols in term of time complexity,system throughput,and communication complexity. | LIU Xiaohui QIAN Zhihong ZHAO Yanhang GUO Yuqi | 2014 | China Communications2014,11,7: | 16 |

| 3 | Unravelling Crystal Structures of Covalent Organi Frameworks by Electron Diffraction Tomography显示文摘Featuring the art of covalent chemistry on 2D and 3D with molecular precision,covalent organic frameworks(COFs)have attracted immense interests from inorganic,organic,polymer,materials and energy chemistry.However,due to the synthetic challenge of'crystallization problem',structural determination of COFs has been the bottle-neck in speeding up their discovery and design,as well as building up their structureproperty relation.Electron diffraction tomography(EDT)has been developed to determine crystal structures of COFs with only sub-micrometer sized single crystals,which enabled the ob initio determination of crystal structure,molecular connectivity,pore metrics,and host-guest interaction at the atomic level.In this review,w e summarized the recent developments of EDT for addressing challenges in structure determinations of such e-beam sensitive,organic porous crystals,covering comprehensively automatic data collection,low dose,cryogenic protocols,structural solution method,powder X-ray diffraction refinement,and high-resolution transmission electron microscopy(HRTEM)imaging techniques.We do believe the EDT will propel this field into the new era of COF chemistry with atomic precision,and we envision the wide application of artificial intelligence will promote the structural determination and particle analysis of COFs and related materials。 | Tu Sun Wei Lei Yanhang Ma Yue-Biao Zhang | 2020 | Chinese Journal of Chemistry2020,38,10: | 5 |
| 4 | Effect of^3B Group in Rings on Special Dispersion of B2O3-SiO2-ZrO2-Ta2O5-Na2O System Glass显示文摘Borosilicate glasses,with x B_2O_3-(60-x)SiO_2-8ZrO_2-8Ta_2O_5-24Na_2O(7≤x≤59 mol%)composition,were fabricated by melt-quenching technique.NMR,UV-Vis,Raman and IR spectroscopic studies were utilized to investigate the structure of fabricated glasses.The NMR spectrum was deconvoluted into five Gaussian bands,assigned to ~4B(0B,4Si),~4B(1B,3Si),~4B(2B,2Si),~3B(rings)and ~3B(loose),to get their quantitative information.The relative dispersion deviation?P_(g,F) was attributed to the relative quantity of ~3B(rings)but not all ~3B groups,and B_2O_3 existed mainly as[BO_3]in rings firstly,and then as[BO_3]in loose condition.The UV-Vis spectra revealed that the quantity of non-bridging oxygen increased firstly and then decreased with increasing concentration of B_2O_3.Acting as complementary techniques,Raman and IR measurements revealed that four-coordinated boron and silica mainly existed as ~4B-O-B,and Si-O-Si in Q^2,respectively,as chain structure but not framework structure,and[B?_4]units prefered connections with borate rather than with silicate entities of the glass network in these studied glasses.In addition,the conclusion also certified that ~3B in'loose'condition located in lower wavenumbers between 1 200-1 600 cm^(-1) in Raman spectra. | 许晓典 WANG Yanhang ZU Chengkui ZHOU Peng | 2018 | Journal of Wuhan University of Technology(Materials Science)2018,33,5: | 2 |
| 5 | Crystallization Kinetics of Lithium Aluminum Germanium Phosphate Glass by DSC Technique显示文摘The crystallization kinetics of Li2O-Al2O3-GeO2-P2O5 (LAGP) glass fabricated via the conventional melt-quenching method was studied by differential scanning calorimetry (DSC) under non-isothermal condition at different heating rates. The activation energy of glass transition Eg is 634.4 kJ/mol, indicating that LAGP glass is easy to crystallize at an elevated temperature. The activation energy of crystallization Ec and Avrami index n obtained from Matusita's model are 442.01 kJ/mol and 1.7, respectively. The value of n reveals that bulk crystallization predominates slightly over surface crystallization during crystallization process. LAGP glass-ceramics after different heat treatments have the same crystalline phases determined as major phase LiGe2(PO4)3, with AlPO4 and GeO2 as their impurity phases. | 何坤 WANG Yanhang 祖成奎 LIU Yonghua ZHAO Huifeng HAN Bin CHENG Jiang | 2012 | Journal of Wuhan University of Technology(Materials Science)2012,27,1: | 2 |
| 6 | Diffusion behavior of Nb element in high Nb containing TiAl Alloys by reactive hot pressing显示文摘Diffusion behavior of Nb in elemental powder metallurgy high Nb containing TiAl alloys was investigated. The results show that Nb element dissolves into the matrix by diffusion. Pore nests are formed in situ after Nb diffusion. With the increase in hot pressing temperature, the diffusion of Nb will be more sufficient, and the microstructure is more homo-geneous. Nb element diffuses completely at 1400°C. Meanwhile, compression deformation and agglomeration phenomena of pores are observed in some pore nests. Hot isostatic pressing (HIP) treatment can only efficiently decrease but not eliminate porosity completely. | WANG Yanhang LIN Junpin HE Yuehui WANG Yanli CHEN Guoliang | 2006 | Rare Metals2006,25,4: | 2 |
| 7 | Post-synthesis and structural evolution of hollow titanium silicalite-1 with solvent-free method显示文摘Generating hollow structure inside titanium silicalite-1(TS-1)is a widely used method to improve its liquid-phase oxidation catalytic performance in industry.However,traditional dissolution-recrystallization method usually required a large amount of aqueous solution of organic template,leading to unfavorable polluted waste,low production efficiency,and high manufacture cost.Here,a facile and environmental friendly strategy was proposed for the post-synthesis of hollow TS-1 zeolite with a solventfree method utilizing NH4HCO3 and tetrapropylammounium bromide as selective etching agents,which reduced the usage of organic template and avoided the liquid waste.The high crystallinity,the microporous structure,and the active Ti sites were preserved at a high product yield(>93%).The formation mechanism of hollow structure was also investigated by exploring effects of different reactants and experimental parameters.Meanwhile,the obtained hollow TS-1 showed an outstanding performance in the epoxidation of 1-hexene in comparison to the parent zeolite. | Yaqi Fan Xianchen Gong Xiaomeng Si Changjiu Xia Peng Wu Yanhang Ma | 2023 | Nano Research2023,16,1: | 1 |
| 8 | Effects of Recrystallization Parameters on the Formation of Hollow Silicalite-1 Zeolite显示文摘Hollow silicalite-1 zeolite can be readily fabricated by hydrothermally treating the parent silicalite-1 with tetrapropylammonium hydroxide. A dissolution-recrystallization mechanism has been previously proposed to explain the formation of such hollow structures, but detailed information of this formation process still remains unclear. Herein, by tracking the evolvement of the hollow voids and morphology of the silicalite-1 under various treatments using XRD, SEM, TEM and N2 adsorption/desorption techniques, we systematically studied the formation process of the hollow structure of silicalite-1 zeolite and discovered that the organic template, water, treating temperature and time can significantly influence the morphology and size of hollow structure inside silicalite-1 zeolite crystals. Generally, a diluted synthesis medium with high template content under suitable temperature(for instance 170 °C) and extended treatment time favors the formation of single hexagonal hollow structure within silicalite-1 zeolites;while other conditions favor the formation of rounded hollow voids or even multiple-voids within silicalite-1 zeolites. | Tan Cheng Dong Zhuoya Sun Tu Zhang Yaping Zhang Guanqun Xia Changjiu Ma Yanhang | 2019 | China Petroleum Processing & Petrochemical Technology2019,21,4: | 1 |
| 9 | New Algorithm Rules Out Acute-on-chronic Liver Failure Development within 28 Days from Acute Decompensation of Cirrhosis显示文摘Background and Aims:Approximately 10%of patients with acute decompensated(AD)cirrhosis develop acute-on-chronic liver failure(ACLF)within 28 days.Such cases have high mortality and are difficult to predict.Therefore,we aimed to establish and validate an algorithm to identify these patients on hospitalization.Methods:Hospitalized patients with AD who developed ACLF within 28 days were considered pre-ACLF.Organ dysfunction was defined accord-ing to the chronic liver failure-sequential organ failure as-sessment(CLIF-SOFA)criteria,and proven bacterial infec-tion was taken to indicate immune system dysfunction.A retrospective multicenter cohort and prospective one were used to derive and to validate the potential algorithm,re-spectively.A miss rate of<5%was acceptable for the calcu-lating algorithm to rule out pre-ACLF.Results:In the deri-vation cohort(n=673),46 patients developed ACLF within 28 days.Serum total bilirubin,creatinine,international normalized ratio,and present proven bacterial infection at admission were associated with the development of ACLF.AD patients with≥2 organ dysfunctions had a higher risk for pre-ACLF patients[odds ratio=16.58195%confidence interval:(4.271-64.363),p<0.001].In the derivation co-hort,67.5%of patients(454/673)had≤1 organ dysfunction and two patients(0.4%)were pre-ACLF,with a miss rate of 4.3%(missed/total,2/46).In the validation cohort,65.9%of patients(914/1388)had≤1 organ dysfunction,and four(0.3%)of them were pre-ACLF,with a miss rate of 3.4%(missed/total,4/117).Conclusions:AD patients with≤1 organ dysfunction had a significantly lower risk of developing ACLF within 28 days of admission and could be safely ruled out with a pre-ACLF miss rate of<5%. | Xiaoting Tang Hai Li Guohong Deng Xin Zheng Xianbo Wang Yan Huang Yanhang Gao Zhongji Meng Zhiping Qian Feng Liu Xiaobo Lu Yu Shi Beiling Li Wenyi Gu Xiaomei Xiang Yan Xiong Yixin Hou Jun Chen Na Gao Sen Luo Liujuan Ji Jing Li Rongjiong Zheng Haotang Ren Jinjun Chen | 2023 | Journal of Clinical and Translational Hepatology2023,11,3: | 1 |
| 10 | Two-Dimensional Metal-Organic Frameworks with Unique Oriented Layers for Oxygen Reduction Reaction:Tailoring the Activity through Exposed Crystal Facets显示文摘As one of the most important families of porous materials,metal–organic frameworks(MOFs)have well-defined atomic structures.This provides ideal models for investigating and understanding the relationships between structures and catalytic activities at the molecular level.However,the active sites on the edges of two-dimensional(2D)MOFs have rarely been studied,as they are less exposed to the surfaces.Here,for the first time,we synthesized and observed that the 2D layers could align perpendicular to the surface of a 2D zeolitic imidazolate framework L(ZIF-L)with a leaf-like morphology.Owing to this unique orientation,the active sites on the edges of the 2D crystal structure could mostly be exposed to the surfaces.Interestingly,when another layer of ZIF-L-Co was grown heteroepitaxially onto ZIF-L-Zn(ZIF-L-Zn@ZIF-L-Co),the two layers shared a common b axis but rotated by 90°in the ac plane.This demonstrated that we could control exposed facets of the 2D MOFs.The ZIF-L-Co with more exposed edge active sites exhibited high electrocatalytic activity for oxygen reduction reaction.This work provides a new concept of designing unique oriented layers in 2D MOFs to expose more edge-active sites for efficient electrocatalysis. | Yanzhi Wang Tu Sun Amir H.B.Mostaghimi Tiago J.Goncalves Zuozhong Liang Yuye Zhou Wei Zhang Zhehao Huang Yanhang Ma Rui Cao Samira Siahrostami Haoquan Zheng | 2022 | CCS Chemistry2022,4,5: | 1 |

| 13 | Multiple enhancements of rate oscillations by non-Gaussian noise in NO reduction with CO on Pt(100)显示文摘The effect of the non-Gaussian colored noise(NGN) on the dynamics of nonlinear systems has attracted increasing attention.This work numerically studied the effect of a particular kind of the NGN,mainly in terms of its departure from Gaussian noise,on the rate oscillations(RO) in the catalytic reduction of NO with CO on Pt(100) surfaces.It was found that power spectrum density changes non-monotonically and the signal-to-noise ratio shows several peaks with increasing departure,demonstrating the presence of'departure-induced multiple resonance'.Since the departure of the NGN determines the probability distribution and hence denotes the type of the noise,the phenomenon of'departure-induced multiple resonance'not only gives multiple enhancements of the RO by virtue of the departure of the NGN,but also implies that,besides Gaussian noise,various other types of noise may enhance the RO in the surface catalytic reaction systems. | GONG YuBing,XIE YanHang & HAO YingHang School of Physics and Electronic Engineering,Ludong University,Yantai 264025,China | 2010 | Science China Chemistry2010,53,1: | 1 |
| 14 | Effect of gating currents of ion channels on the collective spiking activity of coupled Hodgkin-Huxley neurons显示文摘Based on the coupled stochastic Hodgkin-Huxley neurons, we numerically studied the effect of gating currents of ion channels, as well as coupling and the number of neurons, on the collective spiking rate and regularity in the coupled system. It was found, for a given coupling strength and with a relatively large number of neurons, when gating currents are applied, the collective spiking regularity decreases; meanwhile, the collective spiking rate increases, indicating that gating currents can aggravate the de-synchronization of the spikings of all neurons. However, gating currents caused hardly any effect in the spiking of any individual neuron of the coupled system. This result, different from the reduction of the spiking rate by gating currents in a single neuron, provides a new insight into the effect of gating cur-rents on the global information processing and signal transduction in real neural systems. | YuBing Gong YanHang Xie Bo Xu XiaoGuang Ma | 2009 | Science China Chemistry2009,52,1: | 1 |
| 15 | Colored noise-enhanced intrinsic stochastic oscillations in CO oxidation on nanometer-sized Pd particles显示文摘How colored Gaussian noise (CN) affects the intrinsic stochastic oscillations (ISO) of CO oxidation on a nm-sized Pd particle is studied. It is found that the optimal ISO can be enhanced not only by a CN with appropriate noise intensity, but by a CN with appropriate correlation times. Moreover, the optimal ISO can be most greatly enhanced by the CN when the noise intensity or the correlation time is optimal. This result shows that external noise may, via its interplay with the internal noise of the system, play a constructive role in the ISO of the system, and the ISO can employ the external noise to reach a best oscillation performance. | YanHang Xie YuBing Gong Bo Xu FuWen Sun | 2009 | Science China Chemistry2009,52,7: | 1 |

| 17 | Tiny MEMS-Based Pressure Sensors in the Measurement of Intracranial Pressure显示文摘This study presents a tiny pressure sensor which is used to measure the Intracranial Pressure(ICP). The sensor is based on the piezoresistive effect. The piezoresistive pressure sensor is simulated and designed by using nonlinear programming optimizing and Finite Element Analysis(FEA) tools. Two kinds of sensor sizes are designed in the case of childhood and adult. The sensors are fabricated by Microelectro Mechanical Systems(MEMS)process. The test results yield sensitivities of 1.033 10 2mV/kPa for the childhood type detection and 1.257 10 2mV/kPa for the adult detection with sensor chip sizes of 0.40 0.40 mm2and 0.50 0.50 mm2,respectively. A novel method for measuring ICP is proposed because of the tiny sizes. Furthermore,relative errors for sensitivity of pressure sensors are limited within 4.76%. Minimum Detectable Pressure(MDP) reaches 128.4 Pa in average. | Yanhang Zhang Zhaohua Zhang Bo Pang Li Yuan Tianling Ren | 2014 | Tsinghua Science and Technology2014,19,2: | 1 |

| 20 | Densification behavior of high Nb containing TiAl alloys through reactive hot pressing显示文摘Densification behavior of high Nb containing TiAl alloys through reactive hot pressing was investigated. The results showed that the density of the sample hot pressed at 1400°C could reach a near full density of 98.37%. However, the densification abnormality was observed at 1500°C. The diffusion of elemental Nb during microstructural evolution is an important aspect affecting densification, which will form pore nests. With the increase of hot pressing temperature, the diffusion of Nb becomes more adequate. HIP (Hot isostatic pressing) treatment can only decrease porosity to some extent, but cannot eliminate it completely. | Yanhang Wang Junpin Lin Yuehui He Yanli Wang Guoliang Chen | 2007 | Journal of University of Science and Technology Beijing2007,14,3: | 0 |
