| 2 | Improvement in Resolution of Multiphoton Scanning Structured Illumination Microscopy via Harmonics显示文摘We describe a multiphoton(mP)-structured illumination microscopy(SIM)technique,which demonstrates substantial improvement in image resolution compared with linear SIM due to the nonlinear response of fluorescence.This nonlinear response is caused by the effect of nonsinusoidal structured illumination created by scanning a sinusoidally modulated illumination to excite an mP fluorescence signal.The harmonics of the structured fluorescence illumination are utilised to improve resolution.We present an mP-SIM theory for reconstructing the super-resolution image of the system.Theoretically,the resolution of our m P-SIM is unlimited if all the high-order harmonics of the nonlinear response of fluorescence are considered.Experimentally,we demonstrate an 86 nm lateral resolution for two-photon(2P)-SIM and a 72 nm lateral resolution for second-harmonic-generation(SHG)-SIM.We further demonstrate their application by imaging cells stained with F-actin and collagen fibres in mouse-tail tendon.Our method can be directly used in commercial mP microscopes and requires no specific fluorophores or high-intensity laser. | Lei Wang Xiaomin Zheng Jie Zhou Meiting Wang Jiajie Chen Youjun Zeng Gaixia Xu Ying Wang Haixia Qiu Yonghong Shao Junle Qu Bruce Zhi Gao Ying Gu | 2022 | Engineering2022，，9： | 1 |
| 3 | High-Entropy Perovskite Oxide: A New Opportunity for Developing Highly Active and Durable Air Electrode for Reversible Protonic Ceramic Electrochemical Cells显示文摘Reversible proton ceramic electrochemical cell(R-PCEC)is regarded as the most promising energy conversion device,which can realize efficient mutual conversion of electrical and chemical energy and to solve the problem of large-scale energy storage.However,the development of robust electrodes with high catalytic activity is the main bottleneck for the commercialization of R-PCECs.Here,a novel type of high-entropy perovskite oxide consisting of six equimolar metals in the A-site,Pr_(1/6)La_(1/6)Nd_(1/6)Ba_(1/6)Sr_(1/6)Ca_(1/6)CoO_(3−δ)(PLN-BSCC),is reported as a high-performance bifunctional air electrode for R-PCEC.By harnessing the unique functionalities of multiple ele-ments,high-entropy perovskite oxide can be anticipated to accelerate reaction rates in both fuel cell and electrolysis modes.Especially,an R-PCEC utilizing the PLNBSCC air electrode achieves exceptional electrochemical performances,demonstrating a peak power density of 1.21 W cm^(−2)for the fuel cell,while simultaneously obtaining an astonishing current density of−1.95 A cm^(−2)at an electrolysis voltage of 1.3 V and a temperature of 600℃.The significantly enhanced electrochemical performance and durability of the PLNBSCC air electrode is attributed mainly to the high electrons/ions conductivity,fast hydration reactivity and high configurational entropy.This research explores to a new avenue to develop optimally active and stable air electrodes for R-PCECs. | Zuoqing Liu Zhengjie Tang Yufei Song Guangming Yang Wanru Qian Meiting Yang Yinlong Zhu Ran Ran Wei Wang Wei Zhou Zongping Shao | 2022 | Nano-Micro Letters2022，14，12： | 1 |
| 4 | Size engineering of 2D MOF nanosheets for enhanced photodynamic antimicrobial therapy显示文摘Although porphyrin-based metal-organic frameworks(MOFs)have been widely explored as photosensitizers for photodynamic therapy,how the size will affect the light-induced catalytic activity for generation of reactive oxygen species(ROS)still remain unclear.Herein,we first report the size-controlled synthesis of two-dimensional(2D)porphyrin-based PCN-134 MOF nanosheets by a two-step solvothermal method to explore the size effect on its PDT performance,thus yielding enhanced photodynamic antimicrobial therapy.By simply controlling the reaction temperature in the synthesis process,the bulk PCN-134 crystal,large PCN-134(L-PCN-134)nanosheets with a lateral size of 2–3μm and thickness of 33.2–37.5 nm and small PCN-134 nanosheets(S-PCN-134)with a lateral size of 160–180 nm and thickness of 9.1–9.7 nm were successfully prepared.Interestingly,the S-PCN-134 nanosheets exhibit much higher photodynamic activity for ROS generation than that of the bulk 3D PCN-134 crystal and L-PCN-134 nanosheets under a660 nm laser irradiation,suggesting that the photodynamic activity of PCN-134 MOF increases when the size reduces.Therefore,the S-PCN-134 nanosheets show much enhanced performance when used as a photosensitizer for photodynamic antimicrobial activity and wound healing. | Baoli Xue Xiwen Geng Haohao Cui Huiying Chen Zhikang Wu Hong Chen Hai Li Zhan Zhou Meiting Zhao Chaoliang Tan Jingguo Li | 2023 | Chinese Chemical Letters2023，34，9： | 0 |
| 5 | Bismuth doped Sr_(2)Fe_(1.5)Mo_(0.5)O_(6)-δdouble perovskite as a robust fuel electrode in ceramic oxide cells for direct CO_(2)electrolysis显示文摘Electrochemical conversion of CO_(2)to CO is an economically feasible method for mitigating greenhouse gas emissions.Among various electrochemical approaches,solid oxide electrolysis cells(SOECs)show high potential for CO_(2)reduction reaction(CO_(2)-RR)due to their ability to operate at high temperatures,resulting in fast reaction kinetics and increased efficiency.Considering their main energy loss is still associated with the large overpotential at the fuel electrode,the development of the highly efficient and durable cathode for SOECs has been extensively searched after.Here,we propose an A-site doping strategy to enhance the properties of Sr_(2)Fe_(1.5)Mo_(0.5)O_(6)−δ(SFM),which improve its performance as a cathode in SOECs for CO_(2)-RR,demonstrating favorable activity and durability.The structural and physiochemical characterizations,together with DFT calculations,show that the partial replacement of Sr by Bi in the SFM double perovskite not only improves CO 2 adsorption capability at the catalyst surface but also enhances oxygen ionic conduction inside the bulk oxide,resulting in enhanced CO_(2)electrocatalysis performance in SOECs.Specifically,a La_(0.8)Sr_(0.2)Ga_(0.8)Mg_(0.2)O_(3)−δ(LSGM)electrolyte-supported single cell with the new Bi-doped SFM cathode demonstrates a large current density of 1620 mA cm^(−2) at a cell potential of 1.6 V at 850°C with good operational stability up to 200 h.Bi-doped SFM thus represents a highly promising cathode for ceramic CO_(2)electrolyzers and could accelerate our transition towards a carbon-neutral society. | Meiting Yang Zhen Yao Shuai Liu Jun Wang Anwei Sun Haoran Xu Guangming Yang Ran Ran Wei Zhou Gang Xiao Zongping Shao | 2023 | Journal of Materials Science & Technology2023，，33： | 0 |
