1Self-Healing,Self-Adhesive and Stable Organohydrogel-Based Stretchable Oxygen Sensor with High Performance at Room Temperature显示文摘With the advent of the 5G era and the rise of the Internet of Things,various sensors have received unprecedented attention,especially wearable and stretchable sensors in the healthcare field.Here,a stretchable,self-healable,self-adhesive,and room-temperature oxygen sensor with excellent repeatability,a full concentration detection range(0-100%),low theoretical limit of detection(5.7 ppm),high sensitivity(0.2%/ppm),good linearity,excellent temperature,and humidity tolerances is fabricated by using polyacrylamide-chitosan(PAM-CS)double network(DN)organohydrogel as a novel transducing material.The PAM-CS DN organohydrogel is transformed from the PAM-CS composite hydrogel using a facile soaking and solvent replacement strategy.Compared with the pristine hydrogel,the DN organohydrogel displays greatly enhanced mechanical strength,moisture retention,freezing resistance,and sensitivity to oxygen.Notably,applying the tensile strain improves both the sensitivity and response speed of the organohydrogel-based oxygen sensor.Furthermore,the response to the same concentration of oxygen before and after self-healing is basically the same.Importantly,we propose an electrochemical reaction mechanism to explain the positive current shift of the oxygen sensor and corroborate this sensing mechanism through rationally designed experiments.The organohydrogel oxygen sensor is used to monitor human respiration in real-time,verifying the feasibility of its practical application.This work provides ideas for fabricating more stretchable,self-healable,self-adhesive,and high-performance gas sensors using ion-conducting organohydrogels.Yuning Liang Zixuan Wu Yaoming Wei Qiongling Ding Meital Zilberman Kai Tao Xi Xie Jin Wu 2022Nano-Micro Letters2022,14,3:5
2Humidity Sensing of Stretchable and Transparent Hydrogel Films for Wireless Respiration Monitoring显示文摘Respiratory monitoring plays a pivotal role in health assessment and provides an important application prospect for flexible humidity sensors.However,traditional humidity sensors suffer from a trade-off between deformability,sensitivity,and transparency,and thus the development of high-performance,stretchable,and low-cost humidity sensors is urgently needed as wearable electronics.Here,ultrasensitive,highly deformable,and transparent humidity sensors are fabricated based on cost-effective polyacrylamide-based double network hydrogels.Concomitantly,a general method for preparing hydrogel films with controllable thickness is proposed to boost the sensitivity of hydrogel-based sensors due to the extensively increased specific surface area,which can be applied to different polymer networks and facilitate the development of flexible integrated electronics.In addition,sustainable tapioca rich in hydrophilic polar groups is introduced for the first time as a second cross-linked network,exhibiting excellent water adsorption capacity.Through the synergistic optimization of structure and composition,the obtained hydrogel film exhibits an ultrahigh sensitivity of 13,462.1%/%RH,which is unprecedented.Moreover,the hydrogel film-based sensor exhibits excellent repeatability and the ability to work normally under stretching with even enhanced sensitivity.As a proof of concept,we integrate the stretchable sensor with a specially designed wireless circuit and mask to fabricate a wireless respiratory interruption detection system with Bluetooth transmission,enabling real-time monitoring of human health status.This work provides a general strategy to construct high-performance,stretchable,and miniaturized hydrogel-based sensors as next-generation wearable devices for real-time monitoring of various physiological signals.Yuning Liang Qiongling Ding Hao Wang Zixuan Wu Jianye Li Zhenyi Li Kai Tao Xuchun Gui Jin Wu 2022Nano-Micro Letters2022,14,11:5
3Scientific objectives of the Hot Universe Baryon Surveyor(HUBS) mission显示文摘The Hot Universe Baryon Surveyor(HUBS) is a proposed space-based X-ray telescope for detecting X-ray emissions from the hot gas content in our universe. With its unprecedented spatially-resolved high-resolution spectroscopy and large field of view,the HUBS mission will be uniquely qualified to measure the physical and chemical properties of the hot gas in the interstellar medium, the circumgalactic medium, the intergalactic medium, and the intracluster medium. These measurements will be valuable for two key scientific goals of HUBS, namely to unravel the AGN and stellar feedback physics that governs the formation and evolution of galaxies, and to probe the baryon budget and multi-phase states from galactic to cosmological scales. In addition to these two goals, the HUBS mission will also help us solve some problems in the fields of galaxy clusters, AGNs, difuse X-ray backgrounds, supernova remnants, and compact objects. This paper discusses the perspective of advancing these fields using the HUBS telescope.Joel Bregman Renyue Cen Yang Chen Wei Cui Taotao Fang Fulai Guo Edmund Hodges-Kluck Rui Huang Luis C.Ho Li Ji Suoqing Ji Xi Kang Xiaoyu Lai Hui Li Jiangtao Li Miao Li Xiangdong Li Yuan Li Zhaosheng Li Guiyun Liang Helei Liu Wenhao Liu Fangjun Lu Junjie Mao Gabriele Ponti Zhijie Qu Chenxi Shan Lijing Shao Fangzheng Shi Xinwen Shu Lei Sun Mouyuan Sun Hao Tong Junfeng Wang Junxian Wang Q.Daniel Wang Song Wang Tinggui Wang Weiyang Wang Zhongxiang Wang Dandan Xu Haiguang Xu Heng Xu Renxin Xu Xiaojie Xu Yongquan Xue Hang Yang Feng Yuan Shuinai Zhang Yuning Zhang Zhongli Zhang Yuanyuan Zhao Enping Zhou Ping Zhou 2023Science China(Physics,Mechanics & Astronomy)2023,66,9:1

5Psychological and Emotional Responses during Different Stages of the COVID-19 Pandemic Based on a Survey of a Mental Health Hotline显示文摘Background:The coronavirus(COVID-19)outbreak in 2019 triggered psychological and emotional responses.This research investigates the psychological status and emotional problems of those who sought psychological assistance during the epidemic period by calling a mental health hotline.Methods:This study aims to combine qualitative and quantitative research.Descriptive analysis was used for undertaking qualitative research.We ana-lyzed the data from group 1(n=706),in which the people used the mental health hotline from 25 January 2020 to 23 June 2020.A self-designed questionnaire was developed in accordance with the classification and sum-marized items from group 1’s psychological problems and emotional status.To implement the quantitative research,we conducted a cross-sectional descriptive survey and used the self-compiled scale and HADS to inves-tigate group 2(n=553)from May 2020 to June 2020.Results:Descriptive statistics and comparative analysis revealed that:①Visitors mainly reported behavior,emotional,family relationship problems and sleep disorders.②Anxiety,comorbidities,sleep disorders and coping problems were the most frequently reported problems.③There were significant differences in the number of visitors experiencing various problems or exhibiting harmful behaviors(sorrow,worry,fear,depression,sleep disorders,self-harm or suicide,and coping problems,anxiety,hypochondria,and comorbidity)in the four stages of the epidemic.④More than a quarter of participants still suffered from anxiety or depression in the later stages of the epidemic.Conclusion:Different problems manifested at different stages of the epidemic,and psychological interventions and assistance should be tailored to reflect this.Shuna Peng Xiaohong Luo Shiyu Liang Fengning Deng Yuning Liu Hong Zeng Xuesong Yang 2022International Journal of Mental Health Promotion2022,24,5:0
6ACE2-targeting monoclonal antibody as potent and broad-spectrum coronavirus blocker显示文摘The evolution of coronaviruses,such as SARS-CoV-2,makes broad-spectrum coronavirus preventional or therapeutical strategies highly sought after.Here we report a human angiotensin-converting enzyme 2(ACE2)-targeting monoclonal antibody,3E8,blocked the S1-subunits and pseudo-typed virus constructs from multiple coronaviruses including SARS-CoV-2,SARS-CoV-2 mutant variants(SARS-CoV-2-D614G,B.1.1.7,B.1.351,B.1.617.1,and P.1).Yuning Chen Ya-Nan Zhang Renhong Yan Guifeng Wang Yuanyuan Zhang Zhe-Rui Zhang Yaning Li Jianxia Ou Wendi Chu Zhijuan Liang Yongmei Wang Yi-Li Chen Ganjun Chen Qi Wang Qiang Zhou Bo Zhang Chunhe Wang 2021Signal Transduction and Targeted Therapy2021,6,9:0
7Enhancement of ionic conductivity and fracture toughness by infiltrating porous Li_(0.33)La_(0.56)TiO_(3) pellets显示文摘Although solid-state lithium electrolytes have the potential to reduce the safety issues associated with organic liquid electrolytes,disadvantages such as low total conductivity,large interface impedance,and delamination of the interface due to cyclic stress still need to be addressed.The solid-state lithium-ion conductor Li_(0.33)La_(0.56)TiO_(3)(LLTO) was prepared via a hydrothermal route by using CTAB as templates in this paper.Perovskite LLTO with micro-porous channels was obtained and the total conductivity is comparable to the non-porous LLTO.Porous LLTO pellets are infiltrated with the non-porous LLTO precursor solution,and the total conductivities of the infiltrated porous LLTO are all higher than those without infiltration.After infiltration,the porous LLTO calcined at 600℃ achieves the highest total conductivity,7.88×10^(-5) S/cm.The fracture toughness of the infiltrated LLTO is higher than that of the non-porous LLTO.The results demonstrate a new way to prepare solid-state lithium-ion conductors with high ionic conductivity and great tolerance to cyclic stress.Xiaojuan Lu Mingyang Duan Jingyu Xiang Yuning Liang Songtao Liu 2024Journal of Rare Earths2024,42,2:0
8Effects of La^(3+),Ce^(3+) on nitrogen removal in sequencing batch reactor显示文摘Batch experiments were conducted to study the short-term biological effects of rare earth ions(La^(3+),Ce^(3+))and their mixture on the nitrogen removal in a sequencing batch reactor(SBR).The data showed that higher NH4+–N removal rate,total inorganic nitrogen removal efficiency,and denitrification efficiency were achieved at lower concentrations of rare earth elements(REEs)(<1 mg/L).In the first hour of the aeration stage of SBR,the presence of REEs increased the total inorganic nitrogen removal efficiency and NH4+–N removal effi-ciency by 15.7%and 10%–15%,respectively.When the concentrations of REEs were higher than 1 mg/L,the total inorganic nitrogen removal efficiency decreased,and nitrate was found to accumulate in the effluent.When the concentrations of REEs was up to 50.0 mg/L,the total inorganic nitrogen removal efficiency was less than 30%of the control efficiency with a high level of nitrate.Lower concentrations of REEs were found to accelerate the nitrogen conversion and removal in SBR.Qing XIA Rui LIANG Yuxiang MAO Yuning HONG Lili DING Hongqiang REN Mingyu ZHAO 2009Frontiers of Environmental Science & Engineering2009,3,3:0
9Lpcat3 deficiency promotes palmitic acid-induced 3T3-L1 mature adipocyte inflammation through enhanced ROS generation显示文摘Phosphatidylcholines(PCs)are major phospholipids in the mammalian cell membrane.Structural remodeling of PCs is associated with many biological processes.Lysophosphatidylcholine acyltransferase 3(Lpcat3),which catalyzes the incorporation of polyunsaturated fatty acyl chains into the sn-2 site of PCs,plays an important role in maintaining plasma membrane fluidity.Adipose tissue is one of the main distribution organs of Lpcat3,while the relationship between Lpcat3 and adipose tissue dysfunction during overexpansion remains unknown.In this study,we reveal that both polyunsaturated PC content and Lpcat3 expression are increased in abdominal adipose tissues of high-fat diet-fed mice when compared with chow-diet-fed mice,indicating that Lpcat3 is involved in adipose tissue overexpansion and dysfunction.Our experiments in 3T3-L1 adipocytes show that inhibition of Lpcat3 does not change triglyceride accumulation but increases palmitic acid-induced inflammation and lipolysis.Conversely,Lpcat3 overexpression exhibits anti-inflammatory and anti-lipolytic effects.Furthermore,mechanistic studies demonstrate that Lpcat3 deficiency promotes reactive oxygen species(ROS)generation by increasing NOX enzyme activity by facilitating the translocation of NOX4 to lipid rafts,thereby aggregating 3T3-L1 adipocyte inflammation induced by palmitic acid.Moreover,overexpression of Lpcat3 exhibits the opposite effects.These findings suggest that Lpcat3 protects adipocytes from inflammation during adipose tissue overexpansion by reducing ROS generation.In conclusion,our study demonstrates that Lpcat3 deficiency promotes palmitic acid-induced inflammation in 3T3-L1 adipocytes by enhancing ROS generation.Jiachun Hu Yan Deng Tingbo Ding Jibin Dong Yuning Liang Bin Lou 2023Acta Biochimica et Biophysica Sinica2023,55,1:0
