| 1 | Power generation expansion planning approach considering carbon emission constraints显示文摘Decarbonization of the power sector in China is an essential aspect of the energy transition process to achieve carbon neutrality.The power sector accounts for approximately 40%of China’s total CO_(2) emissions.Accordingly,collaborative optimization in power generation expansion planning(GEP)simultaneously considering economic,environmental,and technological concerns as carbon emissions is necessary.This paper proposes a collaborative mixedinteger linear programming optimization approach for GEP.This minimizes the power system’s operating cost to resolve emission concerns considering energy development strategies,flexible generation,and resource limitations constraints.This research further analyzes the advantages and disadvantages of current GEP techniques.Results show that the main determinants of new investment decisions are carbon emissions,reserve margins,resource availability,fuel consumption,and fuel price.The proposed optimization method is simulated and validated based on China’s power system data.Finally,this study provides policy recommendations on the flexible management of traditional power sources,the market-oriented mechanism of new energy sources,and the integration of new technology to support the attainment of carbon-neutral targets in the current energy transition process. | Hasan Mehedi Xiaobin Wang Shilong Ye Guiting Xue Islam Md Shariful Fang Shi | 2023 | Global Energy Interconnection2023，6，2： | 1 |
| 2 | Evidence-based practice with knowledge, attitude and practice of ophthalmic nursing staffs: a cross-sectional study in south China显示文摘Background:This study aims to investigate the current status and influencing factors of evidence-based practice(EBP)with knowledge,attitude and practice(KAP)of ophthalmic nursing staffs in south China.Methods:Using a convenient sampling method,we selected 429 ophthalmic nursing staffs from 28 ophthalmology specialist hospitals or general hospitals in south China,and investigated their general information and implemented the evidence-based practice questionnaire(EBPQ).Results:The scores of EBP and KAP of ophthalmic nursing staffs in south China from high to low were as follows:practical attitude(4.85±1.07 points),practical behavior(4.42±1.14 points),practical knowledge and skills(4.30±0.65 points).The single factor analysis results showed that the first graduation degree,technical title,scientific research achievements,whether or not participate in EBP training,the frequency of reading literature at ordinary time,and whether or not participate in EBP project were the influencing factors of EBP level;the multi-factor analysis results showed that EBP attitude,EBP knowledge and skills,whether or not participate in EBP training were independent influencing factors of EBP.Conclusions:The ophthalmic nursing staffs in south China have a positive attitude towards EBP,however,their EBP knowledge,skills and behavioral capabilities need to be focused and improved.The ophthalmic nursing administrators should fully master the factors affecting the implementation of EBP,and take effective intervention measurement to improve the EBP abilities of ophthalmic nursing staffs,and promote the development of EBP in ophthalmology specialty. | Xiaomin Fang Huiming Xiao Yu Zhang Guiting Wang Shanshan Luo | 2022 | Annals of Eye Science2022，，1： | 0 |
| 3 | Signal-on bimodal sensing glucose based on enzyme product-etching MnO_(2)nanosheets for detachment of MoS_(2)quantum dots显示文摘The sensitive and rapid detection of blood glucose is very important for monitoring and managing diabetes.Herein,a fluorescent/magnetic bimodal sensing strategy is proposed for glucose detection using a multifunction-responsive nanocomposite(MoS_(2)QDs-MnO_(2)NS).MoS_(2)QDs act as fluorescent probes,and MnO_(2)nanosheets are used as both quenchers and recognizers in this sensing platform.In the presence of glucose-mediated enzyme product(H_(2)O_(2)),MnO_(2)nanosheet is etched,thus releasing MoS_(2)QDs and Mn^(2+)ions,which causes the significantly enhancement of fluorescent and magnetic signals.Furthermore,MoS_(2)QDs-MnO_(2)NS-based fluorescent test paper is constructed for H_(2)O_(2)sensing with the naked eyes.Under optimal conditions,the dual linear ranges of 20-300μmol/L and 40-250μmol/L toward glucose detection are obtained for the fluorescent and magnetic mode,respectively.Furthermore,this bimodal assay exhibits good reproducibility and acceptable accuracy in glucose detection of clinical samples,demonstrating great versatility and flexibility of multifunctional probes in glucose detection. | Lingzhi Chen Xueqin Huang Xueyi Zeng Guiting Fang Weijian Chen Haibo Zhou Xing Zhong Huaihong Cai | 2021 | Chinese Chemical Letters2021，32，6： | 0 |
