| 1 | Bionic Thermosensation Inspired Temperature Gradient Sensor Based on Covalent Organic Framework Nanofluidic Membrane with Ultrahigh Sensitivity显示文摘The ability to precisely monitor temperature at a high resolution is an important task,particularly in terms of safety.Inspired by natural thermosensitive transient receptor potential cation channels,we developed a temperature sensor based on thermaldriven ionic charge separation.To mimic the function of nature,an ionic covalent organic frameworkbased nanofluidic membrane was fabricated.By engineering the membrane to separate two electrolyte solutions,the temperature difference across the membrane can synchronously induce a potential.The high charge density and narrow channel size render extraordinary permselectivity to the membrane,thus offering a thermosensation selectivity of up to 1.25 mV K^(−1),superior to that of any known natural system.Additionally,the generated potential is linearly related to the introduced temperature gradient,thus allowing for precise detection.With these attributes,an alarm device with high thermosensation sensitivity was constructed,demonstrating great promise for environmental temperature monitoring. | Weipeng Xian Pengcheng Zhang Changjia Zhu Xiuhui Zuo Shengqian Ma Qi Sun | 2021 | CCS Chemistry2021，3，11： | 1 |
| 2 | Application of informatics in cancer research and clinical practice:Opportunities and challenges显示文摘Cancer informatics has significantly progressed in the big data era.We summarize the application of informatics approaches to the cancer domain from both the informatics perspective(e.g.,data management and data science)and the clinical perspective(e.g.,cancer screening,risk assessment,diagnosis,treatment,and prognosis).We discuss various informatics methods and tools that are widely applied in cancer research and practices,such as cancer databases,data standards,terminologies,high‐throughput omics data mining,machine‐learning algorithms,artificial intelligence imaging,and intelligent radiation.We also address the informatics challenges within the cancer field that pursue better treatment decisions and patient outcomes,and focus on how informatics can provide opportunities for cancer research and practices.Finally,we conclude that the interdisciplinary nature of cancer informatics and collaborations are major drivers for future research and applications in clinical practices.It is hoped that this review is instrumental for cancer researchers and clinicians with its informatics‐specific insights. | Na Hong Gang Sun Xiuran Zuo Meng Chen Li Liu Jiani Wang Xiaobin Feng Wenzhao Shi Mengchun Gong Pengcheng Ma | 2022 | Cancer Innovation2022，1，1： | 0 |
| 3 | Effects of nanoscale Sn segregation on corrosion behavior of laser powder bed fusion Cu-15Ni-8Sn alloy显示文摘Corrosion resistance of laser powder bed fusion(LPBF)Cu-15Ni-8Sn alloys is crucial towards its practical application in marine engineering.In this work,corrosion behavior of LPBF Cu-15Ni-8Sn alloy was com-prehensively investigated.The results suggest that LPBF Cu-15Ni-8Sn alloy exhibits superior corrosion re-sistance than the conventional casting counterpart and their corrosion behavior is highly associated with Sn segregation.Generally,a triple-layer film will be formed on the surface of LPBF Cu-15Ni-8Sn alloy when being exposed to 3.5 wt%NaCl solution.To be more detailed,the abundance of nanoscale Sn-rich precipitates at the molten pool boundaries promotes the initial formation of a thick inner layer,where Ni and Sn tend to be distributed at inner and outer positions of the layer,respectively.In contrast,the inner layer on molten pools is much thinner ascribed to a lower Sn content,facilitating the earlier nucleation and growth of a compact middle layer that is mainly composed of numerous Cu-rich nanoparticles.At the outmost position,CuO,Cu(OH)_(2) and Ni(OH)_(2) constitute the major composition of the loose layer.The results of this study could contribute to the optimal design and processing of additively manufactured Cu-Ni-Sn alloys. | Pengcheng Zuo Zequn Zhang Xiaohong Qi Zhuangzhuang Liu Jiuyang Xia Junshen Wu Xiaogang Li Bowei Zhang | 2023 | Journal of Materials Science & Technology2023，，27： | 0 |
| 4 | Comparative Analysis on the Stability Mechanism of Droop Control and VID Control in DC Microgrid显示文摘Voltage resonance and fluctuation deteriorate the stability of DC microgrids(DC-MGs)and restrict their popularization.Conventional droop control cannot suppress voltage fluctuation and damp oscillations.Therefore,new control methods,namely,droop+filter control and virtual inertia and damping control,are proposed.These methods differ owing to the addition of low pass filter(LPF)and virtual inertia loop.In this study,the stability of these control methods is investigated comprehensively to understand their differences arising from the use of LPF and inertia loop as well as the underlying dynamic stability mechanism.The leading causes of voltage instability in DC-MGs regulated by droop control are first presented.Subsequently,control methods for solving this issue are compared and their simplified small-signal models are constructed.Based on eigenvalue analysis,the DC-MG is equivalent to a third-order system.Different control effects can be acquired by changing the control parameters and the location of the eigenvalues;furthermore,they can be used to understand the dynamic stability.Eigenvalue analysis can provide parameter design guidelines.Finally,the simulation results verify the validity of the theoretical analysis. | Gang Lin Wei Zuo Yong Li Jiayan Liu Shaoyang Wang Pengcheng Wang | 2021 | Chinese Journal of Electrical Engineering2021，7，1： | 0 |
