| 1 | Synergistic Effect and Electrochromic Mechanism of Nanoflake Li-doped NiO in LiOH Electrolyte显示文摘Inorganic metal oxide electrochromic materials have good application prospects for energy-saving windows in buildings and smart display applications.Therefore,the development of electrochromic films with good cycling stabilities,fast color-change response times,and high coloring efficiencies has attracted considerable attention.In this study,nanoflake Li-doped NiO electrochromic films were prepared using a hydrothermal method,and the films exhibited superior electrochromic performances in the LiOH electrolyte.Li^(+)ions doping increased the ion transmission rates of the NiO films,and effectively promoted the transportation of ions from the electrolyte into NiO films.Meanwhile,the nanoflake microstructure caused the NiO films to have larger specific surface areas,providing more active sites for electrochemical reactions.It was determined that the NiO-Li20%film exhibited an ultra-fast response in the LiOH electrolyte(coloring and bleaching times reached 3 and 1.5 s,respectively).Additionally,the coloration efficiency was 62.1 cm^(2)C^(−1),and good cycling stability was maintained beyond 1500 cycles.Finally,the simulation calculation results showed that Li doping weakened the adsorption strengths of the NiO films to OH^(−),which reduced the generation and decomposition of NiOOH and helped to improve the cycling stabilities of the films.Therefore,the research presented in this article provides a strategy for designing electrochromic materials in the future. | Kejun Xu Liuying Wang Gu Liu Chaoqun Ge Long Wang Weichao Wang Mengzhou Chen | 2023 | Energy & Environmental Materials2023，6，3： | 1 |
| 2 | Lipid-oligonucleotide conjugates for bioapplications显示文摘Lipid-oligonucleotide conjugates(LO N s)are powerful molecular-engineering materials for various applications ranging from biosensors to biomedicine.Their unique amphiphilic structures enable the self-assembly and the conveyance of information with high fidelity.In particular,LONs present remarkable potential in measuring cellular mechanical forces and monitoring cell behaviors.LONs are also essential sensing tools for intracellular imaging and have been employed in developing cell-surface-anchored DNA nanostructures for biomimetic-engineering studies.W hen incorporating therapeutic oligonucleotides or small-molecule drugs,LONs hold promise for targeted therapy.Moreover,LONs mediate the controllable assembly and fusion of vesicles based on DNA-strand displacements,contributing to nanoreactor construction and macromolecule delivery.In this review,we will summarize the general synthesis strategies of LONs,provide some characterization analysis and emphasize recent advances in bioanalytical and biomedical applications.We will also consider the relevant challenges and suggest future directions for building better functional LONs in nanotechnology and materials-science applications. | Xiaowei Li Kejun Feng Long Li Lu Yang Xiaoshu Pan Hoda Safari Yazd Cheng Cui Juan Li Leonid Moroz Yujia Sun Bang Wang Xiang Li Tong Huang Weihong Tan | 2020 | National Science Review2020，7，12： | 1 |
| 3 | Bus Priority Control for Dynamic Exclusive Bus Lane显示文摘One problem with the existing dynamic exclusive bus lane strategies is that bus signal priority strategies with multi-phase priority request at intersections are not adequately considered.The principle of bus signal priority level was designed based on the isolated multi-phase structure principle consideration of the bus signal priority,and a new priority approach for the dynamic exclusive bus lane was proposed.Two types of priority strategies,green extension and red truncation,were proposed for current phase and next phase buses,respectively.The control parameters including minimum green time,green extension time,maximum green time and bus arrival time are calculated.The case studies for this paper were carried out using four consecutive intersections of Huaide Middle Road in Changzhou City.The signal control scheme was designed using the conventional,exclusive bus lane method,the dynamic exclusive bus lane without signal priority method,and the proposed approach,respectively.The authors used the VISSIM simulation platform to evaluate the efficiency of each approach.Results showed that the method of approach can significantly decrease delays caused by social and conventional buses and make up for the negative impact social buses have on the bus rapid transit(BRT)operation,which allows the method to complement the dynamic,exclusive bus lane design. | Zhibo Gao Kejun Long Chaoqun Li Wei Wu Lee.D.Han | 2019 | Computers, Materials & Continua2019，，7： | 0 |
