| 1 | A hierarchical heterostructure of CdS QDs confined on 3D ZnIn_(2)S_(4) with boosted charge transfer for photocatalytic CO_(2) reduction显示文摘Metal sulfide based materials as photocatalysts for energy conversion are essential to produce value-added chemical fuels,but their intrinsically slow carrier dynamics and low activity are yet to be resolved.Herein,we developed a unique heterogeneously nanostructured ZnIn_(2)S_(4)-CdS heterostructure that involves zero-dimensional(0D)CdS quantum dots uniformly confined on three-dimensional(3D)ZnIn_(2)S_(4)nanoflowers,which achieves an excellent catalytic performance of CO_(2) photoconversion under visible-light irradiation.The obtained hierarchical heterostructure can significantly enhance the light harvesting,shorten the migration distance of carriers,and obviously accelerate the transport of electrons.As evidenced by the ultrafast transient absorption spectroscopy,the formed interface can effectively facilitate charge separation and transport.This work opens up a new avenue to carefully design the elaborate heterostructures for achieving optimal charge separation efficiency by lowering interfacial kinetic barriers and energy losses at the interface. | Zezhou Zhu Xiaoxia Li Yunteng Qu Fangyao Zhou Zhiyuan Wang Wenyu Wang Changming Zhao Huijuan Wang Liqiang Li Yagang Yao Qun Zhang Yuen Wu | 2021 | Nano Research2021,14,1: | 6 |
| 2 | Time-domain Approach to the Performance Analysis of GPS Phase Locked Loop显示文摘The frequency-domain approach is widely used in Global positioning system(GPS) receiver tracking loop performance analysis.In realization,the Digital phase-locked loop(DPLL) is used.There is difference between phase errors by traditional frequency-domain analysis and real receiver output because of discretization errors.In order to get more precise result,this paper uses timedomain difference equations to analyze the phase tracking errors under the influence of thermal noise and the dynamic stress on different orders of PLL.The simulation results show that the traditional frequency-domain approach has phase error deviation under long integration time(i.e.,more than 10ms),while the time-domain approach has good accordance with receiver simulation output.Thus,the proposed time-domain approach can provide more precise solution for PLL performance analysis. | ZHOU Hongwei JIN Tian LYU Fangyao WANG Lihua | 2017 | Chinese Journal of Electronics2017,26,2: | 3 |
| 3 | Simultaneous diffusion of cation and anion to access N,S cocoordinated Bi-sites for enhanced CO_(2) electroreduction显示文摘Developing highly active single-atom sites catalysts for electrochemical reduction of CO_(2) is an effective and environmental-friendly strategy to promote carbon-neutral energy cycle and ameliorate global climate issues.Herein,we develop an atomically dispersed N,S co-coordinated bismuth atom sites catalyst(Bi-SAs-NS/C)via a cation and anion simultaneous diffusion strategy for electrocatalytic CO_(2) reduction.In this strategy,the bonded Bi cation and S anion are simultaneously diffused into the nitrogen-doped carbon layer in the form of Bi2S3.Then Bi is captured by the abundant N-rich vacancies and S is bonded with carbons.support at high temperature,formed the N,S co-coordinated Bi sites.Benefiting from the simultaneous diffusion of Bi and S,different electronegative N and S can be effectively co-coordinated with Bi,forming the uniform Bi-N_(3)S/C sites.The synthesized.Bi-SAs-NS/C exhibits a high selectivity towards CO with over 88%Faradaic efficiency in a wide potential range,and achieves a maximum FE_(CO)of 98.3%at-0.8 V vs.RHE with a current density of 10.24 mA·cm^(-2),which can keep constant with negligible degradation in 24 h continuous electrolysis.Experimental results and theoretical calculations reveal that the significantly improved catalytic performance of Bi-SAs-NS/C than Bi-SAs-N/C is ascribed to the replacement of one coordinated-N with low electronegative S in Bi-N_(4)C center,which can greatly reduce the energy barrier of the intermediate formation in rate-limiting step and increase the reaction kinetics.This work provides an effective strategy for rationally designing highly active single-atom sites;catalysts for efficient electrocatalysis with optimized electronic structure. | Zhiyuan Wang Chun Wang Yidong Hu Shuai Yang Jia Yang Wenxing Chen Huang Zhou Fangyao Zhou Lingxiao Wang Junyi Du Yafei Li Yuen Wu | 2021 | Nano Research2021,14,8: | 2 |

| 5 | Impact of COVID-19 Epidemic on the International Food Supply Chain and Countermeasures of Shandong Province显示文摘The COVID-19 epidemic has exerted an impact on the global food supply chain,and also has contributed to the tendency of food hoarding and short supply;strong food demand has led to a rapid rise in international food prices,which has put enormous pressure on China's food import,and domestic food price showed a rise trend accordingly.In order to ensure sufficient and stable supply of China's food market,it is necessary to adhere to the food security strategy of'food self-sufficiency'for a long term.In the spring agricultural production,Shandong Province has taken effective measures to stabilize food production and achieved good results.It has not been greatly affected by the COVID-19 epidemic;however,under the continuous spread of foreign epidemics,we must adhere to the dual hard core operation of epidemic prevention and production,and explore the establishment of technical specifications for agricultural production under normal conditions for epidemic prevention and control to ensure the food security. | Fangyao YUAN Ping YANG Feng XU Tongkai HAN | 2020 | Asian Agricultural Research2020,12,8: | 1 |

| 8 | Intratympanic vs systemic use of steroids as first-line treatment for sudden hearing loss:A meta-analysis of randomized,controlled trials显示文摘Background Sudden sensorineural hearing loss(SSNHL)is a common disease in otology,and steroids play an important role in its treatment.Steroids can be administered systemically or locally,and the efficacies of different administration routes remain controversial.Methods We searched the Cochrane,EMBASE,PubMed,Web of Science,CNKI,Wanfang and Weipu databases for randomized controlled trials(RCTs)on glucocorticoid treatments for SSNHL to compare the efficacy of topical and systemic steroid administration.The Review Manager 5.4 software was used for synthesis of data:the rate of reported hearing improvement and change in pure-tone audiometry(PTA).Results In all the included studies,when intratympanic administration was compared to systemic therapies,the risk difference(RD)using reported hearing improvement as an outcome measure was 0.08(95%CI:0.01–0.14,I2=45%).Using PTA changes as an outcome measure in 4 studies,the mean difference(MD)was 10.43 dB(95%CI:3.68–17.18,I2=81%).Hearing improvement RD was also compared among different types of steroid,recovery criteria,follow-up times and diagnostic criteria,and showed no significant differences exception for recovery criteria(>10 dB)(RD-0.06,95%CI:0.14-0.2,I2=0%).Conclusion As the initial treatment for SSNHL,topical steroids seem to be superior to systemic steroid administration,especially in patients with contraindications to systemic steroids usage.However,further verification based on high-quality research is needed. | Ting Yang Hui Liu Fangyao Chen An Li Zhou Wang Shuangyuan Yang Shiyu Yang Wen Zhang | 2021 | Journal of Otology2021,16,3: | 1 |

Methods : 30 rabbits had undergone ECCE with PC-IOL implantation. PC-IOLs were removed at different stages after operation. 20 PC-IOLs were stained by HE to demonstrate cells on the surface of PC-IOL under light microscopy. 5 PC-IOLs for scanning electron microscopy were observed. 5 membranes were studied by transmission electron microscopy.Results: On 25 implanted PC-IOLs, the incidence of cell adhesion was 100% . The cells adherent to lens included macrophages,fibroblast-like cells,epithelioid cells,giant cells, ultralarge giant cells and lymphocytes. It was seen that there was a thin proteinaceous film on the surface of the implanted PC-IOLs and the membrane was composed of fibrin collagen | Fangyao Yang, Shaozhen Li, Yezi LiuDepartment of Ophthalmology, Nan fang Hospital, First Military Medical University Guangzhou 510515, China Zhangshan Ophthalmic Center, Sun Yat-sen Universily of Medical Sciences , Guangzhou 510055 , China | 1997 | 眼科学报1997,13,1: | 0 |
| 10 | NiCo-LDH nanosheets strongly coupled with GO-CNTs as a hybrid electrocatalyst for oxygen evolution reaction显示文摘The rational fabrication of highly efficient electrocatalysts with low cost toward oxygen evolution reaction(OER)is greatly desired but remains a formidable challenge.In this work,we present a facile and straightforward method of incorporating NiCo-layered double hydroxide(NiCo-LDH)into GO-dispersed CNTs(GO-CNTs)with interconnected configuration.X-ray absorption spectroscopy(XAS)reveals the strong electron interaction between NiCo-LDH and the underlying GO-CNTs substrate,which is supposed to facilitate charge transfer and accelerate the kinetics for OER.By tuning the amount of CNTs,the optimized NiCo-LDH/GO-CNTs composite can achieve a low overpotential of 290 mV at 10 mA·cm^(−2) current density,a small Tafel slope of 66.8 mV·dec^(−1) and robust stability,superior to the pure NiCo-LDH and commercial RuO_(2) in alkaline media.The preeminent oxygen evolution performance is attributed to the synergistic effect stemming from the merits and the intimate electron interaction between LDH and GO-CNTs.This allows NiCo-LDH/GO-CNTs to be potentially applied in an industrial non-noble metal-based water electrolyzer as the anodic catalysts. | Peiqun Yin Geng Wu Xiaoqian Wang Shoujie Liu Fangyao Zhou Lei Dai Xin Wang Bo Yang Zhen-Qiang Yu | 2021 | Nano Research2021,14,12: | 0 |
| 11 | Copy number variation of B1 controls awn length in wheat显示文摘Wheat awns contribute to photosynthesis and grain production.In this study,an F2population and F2:3families from a cross between the awned line 7D12 and the Chinese awnless variety Shiyou 20(SY20)were used to identify loci associated with awn length.Bulked-segregant RNA sequencing and linkage mapping identified a single dominant locus in a 0.3 cM interval on chromosome 5AL.Five genes were in the interval,including the recently cloned awn inhibitor B1.Although a single copy of the B1 gene was detected in 7D12,SY20 carried five copies of the gene.Increased copy number of B1 in SY20enhanced gene expression.Based on sequence variation among the promoter regions of five B1 gene copies in SY20,two dominant markers were developed and found to cosegregate with B1 in a population of 931 wheat accessions.All 77 awnless accessions harbored sequence variations in the B1 promoter regions similar to those of SY20 and thus carried multiple copies of the gene,whereas 15 randomly selected awned wheats carried only one copy.These results suggest that an increase in copy number of the B1 gene is associated with inhibition of awn length. | Jinlong Li Xin Xin Fangyao Sun Zhenzhen Zhu Xiangru Xu Jiatian Yang Xiaoming Xie Jiazheng Yu Xiaobo Wang Sen Li Shilin Tian Baoyun Li Chaojie Xie Jun Ma | 2023 | The Crop Journal2023,11,3: | 0 |
| 12 | Variable step-size adaptive filtering algorithm based on an exponent sin function显示文摘This paper proposes a robust adaptive filter based on the exponent sin cost to improve the capability against Gaussian or multiple types of non-Gaussian noises of the adaptive filtering algorithm when dealing with time-varying/time-invariant linear systems function exponent sin(ExpSin).Then a variable step-size(VSS)-ExpSin algorithm is extended further.Besides,the stepsize,the convergence,and the steady-state performance of the proposed algorithm are validated experimentally.The Monte Carlo simulation results of linear system identification illustrate the principle and efficiency of this proposed adaptive filtering algorithm.Results suggest that the proposed adaptive filtering algorithm has superior performance when estimating the unknown linear systems under multiple-types measurement noises. | Guan Sihai Cheng Qing Zhao Yong Liu Fangyao | 2023 | The Journal of China Universities of Posts and Telecommunications2023,30,1: | 0 |
| 13 | Three-Dimensional Welded Mn_(1) Site Catalysts with nearly 100% Singlet Oxygen Fabrication for Contaminant Elimination显示文摘Reactive oxygen species(ROS)have a significant part in the elimination of recalcitrant organic pollutants and commonly coexist in one advanced oxidation system.It is difficult for us to make clear the effect of the co-instantaneous generation of radicals and nonradicals,which would cover and obscure the transformation pathway.Herein,a coordinate welding process is presented for fabricating accessible Mn1 site catalysts(Mn SSCs)in order to clarify the nonradical(singlet oxygen/^(1)O_(2))generated pathway and transformation in oxidative removal of contaminants.The Mn SSCs achieve nearly 100%^(1)O_(2) fabrication by activating peroxymonosulfate,which displays an excellent sulfamethoxazole elimination performance,super anti-anion interference,and extraordinary stability.As revealed by density functional theory calculations,the Mn SSCs with a special welded three-dimensional nanostructure could significantly boost the activation process by oxidizing the peroxymonosulfate at the interlayer of Mn SSCs and reducing dissolved oxygen on the surface of Mn SSCs.This design of Mn SSCs with a three-dimensional welded nanostructure might offer a potential approach for employing single site catalysts for environmental remediation. | Xiao Ge Donghua Xie Rui-fen Cheng Wenxing Chen Cai Chen Fangyao Zhou Xiaozhi Wang Jie-jie Chen Guo-ping Sheng Yuen Wu | 2023 | Precision Chemistry2023,1,3: | 0 |
| 14 | Design of 1.5 bit quantization correlator in satellite navigation software receiver显示文摘Currently, 1 bit or 2 bit signal quantization is widely used in satellite navigation software receivers. The bit-wise parallel algorithm has been proposed for 1 bit and 2 bit signal quantization, which performs correlation with high efficiency. In order to improve the performance of the correlator, this paper proposes a new 1.5 bit quantization method. Theoretical analyses are made from the aspects of complexity and quantization loss, and performance comparison between 1.5 bit quantization correlator and traditional correlators is discussed. The results show that the 1.5 bit quantization algorithm can save about 30 percent complexity under similar quantization loss, reduce more than 0.5 d B signal noise ratio(SNR) loss under similar complexity. It shows great performance improvement for correlators of satellite navigation software receivers. | Hongwei Zhou Tian Jin Fangyao Lü | 2016 | Journal of Systems Engineering and Electronics2016,27,2: | 0 |
