| 1 | Chemical characteristics of haze particles in Xi'an during Chinese Spring Festival: Impact of fireworks burning显示文摘Fireworks burning releases massive fine particles and gaseous pollutants, significantly deteriorating air quality during Chinese Lunar New Year(LNY) period. To investigate the impact of the fireworks burning on the atmospheric aerosol chemistry, 1-hr time resolution of PM_(2.5) samples in Xi'an during the winter of 2016 including the LNY were collected and detected for inorganic ions, acidity and liquid water content(LWC) of the fine aerosols. PM_(2.5) during the LNY was 167 ± 87 μg/m^3, two times higher than the China National Ambient Air Quality Standard(75 μg/m^3). K^+(28 wt.% of the total ion mass) was the most abundant ion in the LNY period, followed by SO_4^(2-)(25 wt.%) and Cl-(18 wt.%). In contrast, NO_3^-(34 wt.%) was the most abundant species in the haze periods(hourly PM32-2.5> 75 μg/m), followed by SO_4(29.2 wt.%) and NH_4^+(16.3 wt.%), while SO_4^(2-)(35 wt.%) was the most abundant species in the clean periods(hourly PM_(2.5)< 75 μg/m^3), followed by NO_3^-(23.1 wt.%) and NH_4^+(11 wt.%). Being different from the acidic nature in the non-LNY periods, aerosol in the LNY period presented an alkaline nature with a pH value of 7.8 ± 1.3. LWC during the LNY period showed a robust linear correlation with K_2SO_4 and KCl, suggesting that aerosol hygroscopicity was dominated by inorganic salts derived from fireworks burning. Analysis of correlations between the ratios of NO--3/SO_4^(2-) and NH_4^+/SO_4^(2-) indicated that heterogeneous reaction of HNO_3 with NH_3 was an important formation pathway of particulate nitrate and ammonium during the LNY period. | Can Wu Gehui Wang Jiayuan Wang Jianjun Li Yanqin Ren Lu Zhang Cong Cao Jin Li Shuagshuang Ge Yuning Xie Xinpei Wang Guoyan Xue | 2018 | Journal of Environmental Sciences2018,30,9: | 10 |
| 2 | Image formation of brain function in patients suffering from knee osteoarthritis treated with moxibustion显示文摘OBJECTIVES:Functional magnetic resonance imaging(fMRI) technology was used to study changes to the resting state blood flow in the brains of patients with knee osteoarthritis(KOA) before and after treatment with moxibustion at the acupoint of the left Dubi(ST 35) and to probe the cerebral mechanism underlying the effect of moxibustion.METHODS:The resting state brain function of 30 patients with left KOA was scanned with fMRI before and after treatment with moxibustion.The analytic methods of fractional amplitude of low frequency fluctuation(fALFF) and regional homogeneity(ReHo) were used to observe changes in resting state brain function.RESULTS:The fALFF values of the right cerebrum,extra-nucleus,left cerebellum,left cerebrum and white matter of patients after moxibustion treatment were higher than before treatment,and the fALFF values of the precentral gyrus,frontal lobe and occipital lobe were lower than before treatment(P<0.05,K≥85).The ReHo values of the thalamus,extra-nucleus and parietal lobe of patients were much higher than those before moxibustion treatment,and the ReHo values of the right cerebrum,left cerebrum and frontal lobe were lower than before treatment(P<0.05,K≥85).CONCLUSION:The influence of moxibustion on obvious changes in brain regions basically conforms to the way that pain and warmth is transmitted in the body,and the activation of sensitive systems in the body may be objective evidence of channel transmission.The regulation of brain function by moxibustion is not in a single brain region but rather in a network of many brain regions. | Hongwu Xie Fangming Xu Rixin Chen Tianyou Luo Mingren Chen Weidong Fang Fajin Lü Fei Wu Yune Song Jun Xiong | 2013 | Journal of Traditional Chinese Medicine2013,33,2: | 7 |
| 3 | Self-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 | 2022 | Nano-Micro Letters2022,14,3: | 5 |
| 4 | Humidity 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 | 2022 | Nano-Micro Letters2022,14,11: | 5 |
| 5 | Well-construction of Zn_(2)SnO_(4)/SnO_(2)@ZIF-8 core-shell hetero-structure with efficient photocatalytic activity towards tetracycline under restricted space显示文摘Nowadays,efficient removal of antibiotic(e.g.tetracycline,TC) from water bodies has been of great global concern.Hereby,a novel Zn_(2)SnO_(4)/SnO_(2)@ZIF-8 photo-catalyst was first synthesized by a facile selfassembly in-situ growth method.Zn_(2)SnO_(4)/SnO_(2)@ZIF-8 exhibits a remarkable photocatalytic activity towards TC under visible-light driven with a rapid rate constant of 1.5 × 10^(-2)min^(-1), and a removal efficiency of 81.2%,which is superior to some catalysts in the literature.Importantly,the photocatalytic activity of Zn_(2)SnO_(4)/SnO_(2)@ZIF-8 could still remain ~77% after the fifth cycle,indicating its good stability and reusability.The remarkable performances of adsorption and photocatalytic were attributed to associative effects of catalytic activity of Zn_(2)SnO_(4)/SnO_(2)and the unique porous nanostructure and stability of ZIF-8.This work could aid the future design and preparation of novel MOFs composite catalysts for efficient elimination of antibiotics from water. | Jiafei Wu Yuning Jin Danping Wu Xiaoying Yan Na Ma Wei Dai | 2022 | Chinese Journal of Chemical Engineering2022,,12: | 3 |

| 9 | Red blood cell membrane-camouflaged nanoparticles loaded with AIEgen and Poly(I: C) for enhanced tumoral photodynamic-immunotherapy显示文摘Red blood cell(RBC)-mimicking nanoparticles(NPs) offer a promising platform for drug delivery because of their prolonged circulation time, reduced immunogenicity and specific targeting ability. Herein, we report the design and preparation of RBC membrane-bound NPs(M@AP), for tumoral photodynamic-immunotherapy. The M@AP is formed by self-assembly of the positively charged aggregation-induced emission luminogen(AIEgen)(named P2-PPh3) and the negatively charged polyinosinic : polycytidylic acid(Poly(I : C)), followed by RBC membrane encapsulation. P2-PPh3 is an AIE-active conjugated polyelectrolyte with additional photosensitizing ability for photodynamic therapy(PDT), while Poly(I : C) serves as an immune-stimulant to stimulate both tumor and immune cells to activate immunity, and thus reduces tumor cell viability. When applied in tumor-bearing mice, the M@AP NPs are enriched in both the tumor region as a result of an enhanced permeability and retention(EPR)effect, and the spleen because of the homing effect of the RBC-mimicking shell. Upon light irradiation,P2-PPh3 promotes strong ROS generation in tumor cells, inducing the release of tumor antigens(TA). The anti-tumor immunity is further enhanced by the presence of Poly(I : C) in M@AP. Thus, this strategy combines the PDT properties of the AIE-active polyelectrolyte and immunotherapy properties of Poly(I : C) to achieve synergistic activation of the immune system for anti-tumor activity, providing a novel strategy for tumor treatment. | Jun Dai Meng Wu Quan Wang Siyang Ding Xiaoqi Dong Liru Xue Qingqing Zhu Jian Zhou Fan Xia Shixuan Wang Yuning Hong | 2021 | National Science Review2021,8,6: | 1 |

| 14 | Underflow concentration prediction model of deep-cone thickener based on data-driven显示文摘The underflow concentration prediction of deep-cone thickener is a difficult problem in paste filling. The existing prediction model only determines the influence of some parameters on the underflow concentration, but lacks a prediction model that comprehensively considers the thickening process and various factors. This paper proposed a model which analyzed the variation of the underflow concentration from a number of influencing factors in the concentrating process. It can accurately predict the underflow concentration. After preprocessing and feature selection of the history data set of the deep-cone thickener, this model uses the eXtreme gradient boosting(XGBOOST) in machine learning to deal with the relationship between the influencing factors and the underflow concentration, so as to achieve a more comprehensive prediction of the underflow concentration of the deep-cone thickener. The experimental results show that the underflow concentration prediction model based on XGBOOST shows a mean absolute error(MAE) of 0.31% and a running time of 1.6 s on the test set constructed in this paper, which fully meet the demand. By comparing the following three classical algorithms: back propagation(BP) neural network, support vector regression(SVR) and linear regression, we further verified the superiority of XGBOOST under the conditions of this study. | Wang Huan Liu Ting Cao Yuning Wu Aixiang | 2019 | The Journal of China Universities of Posts and Telecommunications2019,26,6: | 0 |

| 16 | Highly efficient base editing in rabbit by using near-PAMless engineered CRISPR/Cas9 variants显示文摘Dear Editor,Base editors can achieve targeted C-to-T and A-to-G conversion without the generation of DNA double-strand breaks(DSBs)or the requirement of a donor template,showing the potential to generate new mutations or to correct pathogenic mutations(Gaudelli et al.,2018).However,for conventional base editors,efficient base editing requires the presence of an NGG protospacer adjacent motif(PAM)that lies 12–16 nt downstream of the target bases,which generally limits the application of these base editors(Gaudelli et al.,2018). | Zhongtian Zhang Xinyu Wu Jie Yang Xin Liu Ruonan Liu Yuning Song | 2023 | Science China(Life Sciences)2023,66,3: | 0 |
| 17 | Response of Distribution Range Against Climate Change and Habitat Preference of Four National Protected Diploderma Species in Tibetan Plateau显示文摘Understanding the spatial distribution and habitat preference for rare and endangered species are essential for effective conservation practice.We examined the spatial distribution and habitat preference of four Diploderma species(Diploderma drukdaypo,D.laeviventre,D.batangense,and D.vela),which are endemic to the Qinghai-Tibet Plateau and are currently under state protection.We used the ensembles of small models(ESM)approach and predicted potential distribution ranges of the species in current and two future climate scenarios(SSP126 and SSP585).The degree of overlap between the predicted distribution ranges and existing natural reserves was further analyzed.Habitat preference was examined using a paired quadrat method.Our results predicted that D.drukdaypo has a current distribution range of 600 km^(2),which would decrease to 50 km^(2)and 55 km^(2)under the SSP126 and SSP585 respectively.For D.laeviventre,the current distribution range is 817 km^(2),with minimum changes in the two future climate scenarios(774 km^(2)and 902 km^(2)).For D.batangense,the current distribution range is 875 km^(2),which would expand to 1522 km^(2)and 3340 km^(2)in the two future climate scenarios.Similarly for D.vela,the current distribution range is 1369 km^(2),which would change to 1825 km^(2)and 2043 km^(2)respectively under the two future climate scenarios.The effect of protection of current nature reserves are likely low for those species;we found no overlap(D.drukdaypo,D.laeviventre)or little overlap(D.batangense 2.04%–3.56%,D.vela 15.52%–16.87%)between the currently designated protection area and distribution range under current and future climate scenarios.For habitat preference,stones appear to be the critical habitat element for those species although different species had different stone requirements.Taken together,we provided critical information on potential distribution ranges and habitat preference for four endangered Diploderma species,and confirmed the inadequacy of current nature reserves.The establishment of new or expansion of existing nature reserves is urgent for the conservation of those species. | Lin SHI Xiudong SHI Yuning CAO Yayong WU Haijuan WEI Youhua CHEN Ziyan LIAO Yin QI | 2023 | Asian Herpetological Research2023,14,4: | 0 |
| 18 | Decorating multiwalled carbon nanotubes with zinc oxide nanoparticles by thermally decomposing Zn-oleate in an organic medium显示文摘Carbon nanotubes decorated with zinc oxide nanoparticles were produced by thermally decomposing a Zn-oleate complex in an octadecene medium.The structure of the ZnO decorating nanotube surfaces was characterized by transmission electron microscopy,scanning electron microscopy and X-ray dif-fraction.The surfaces were shown to be densely and homogeneously covered by ZnO nanoparticles with a size below 10 nm.The nanoparticles had the wurtzite hexagonal crystal structure and showed good adhesion to the nanotubes.The carbon nanotubes decorated by metal oxide nanoparticles were synthesized at relatively low temperature and non-oxidation environment.Moreover,the large-scale production with low cost can be realized. | LI ChenSha QIAO YingJie LI YuNing WU YiLiang | 2009 | Science China(Technological Sciences)2009,52,5: | 0 |
| 19 | A 4H-SiC semi-super-junction shielded trench MOSFET: p-pillar is grounded to optimize the electric field characteristics显示文摘A 4H-SiC trench gate metal-oxide-semiconductor field-effect transistor(UMOSFET)with semi-super-junction shiel-ded structure(SS-UMOS)is proposed and compared with conventional trench MOSFET(CT-UMOS)in this work.The advantage of the proposed structure is given by comprehensive study of the mechanism of the local semi-super-junction structure at the bottom of the trench MOSFET.In particular,the influence of the bias condition of the p-pillar at the bottom of the trench on the static and dynamic performances of the device is compared and revealed.The on-resistance of SS-UMOS with grounded(G)and ungrounded(NG)p-pillar is reduced by 52%(G)and 71%(NG)compared to CT-UMOS,respectively.Additionally,gate ox-ide in the GSS-UMOS is fully protected by the p-shield layer as well as semi-super-junction structure under the trench and p-base regions.Thus,a reduced electric-field of 2 MV/cm can be achieved at the corner of the p-shield layer.However,the quasi-intrinsic protective layer cannot be formed in NGSS-UMOS due to the charge storage effect in the floating p-pillar,resulting in a large electric field of 2.7 MV/cm at the gate oxide layer.Moreover,the total switching loss of GSS-UMOS is 1.95 mJ/cm2 and is reduced by 18%compared with CT-UMOS.On the contrary,the NGSS-UMOS has the slowest overall switching speed due to the weakened shielding effect of the p-pillar and the largest gate-to-drain capacitance among the three.The proposed GSS-UMOS plays an important role in high-voltage and high-frequency applications,and will provide a valuable idea for device design and circuit applications. | Xiaojie Wang Zhanwei Shen Guoliang Zhang Yuyang Miao Tiange Li Xiaogang Zhu Jiafa Cai Rongdun Hong Xiaping Chen Dingqu Lin Shaoxiong Wu Yuning Zhang Deyi Fu Zhengyun Wu Feng Zhang | 2022 | Journal of Semiconductors2022,43,12: | 0 |
| 20 | The effect of tailing lipidation on the bioactivity of antimicrobial peptides and their aggregation tendency Special Issue:Emerging Investigators显示文摘Antimicrobial peptides(AMPs)are potentially powerful alternatives to conven-tional antibiotics in combating multidrug resistance,given their broad spectrum of activity.They mainly interact with cell membranes through surface electrostatic potentials and the formation of secondary structures,resulting in permeability and destruction of target microorganism membranes.Our earlier work showed that two leading AMPs,MSI-78(4–20)and pardaxin(1–22),had potent antimicrobial activ-ity against a range of bacteria.It is known that the attachment of moderate-length lipid carbon chains to cationic peptides can further improve the functionality of these peptides through enhanced interactions with the membrane lipid bilayer,inducing membrane curvature,destabilization,and potential leakage.Thus,in this work,we aimed to investigate the antimicrobial activity,oligomerization propensity,and lipid-membrane binding interactions of a range of N-terminal lipidated analogs of MSI-78(4–20)and pardaxin(1–22).Molecular modeling results suggest that aggregation of the N-lipidated AMPs may impart greater structural stability to the peptides in solu-tion and a greater depth of lipid bilayer insertion for the N-lipidated AMPs over the parental peptide.Our experimental and computationalfindings provide insights into how N-terminal lipidation of AMPs may alter their conformations,with subsequent effects on their functional properties in regard to their self-aggregation behavior,membrane interactions,and antimicrobial activity. | Bruce Lin Andrew Hung William Singleton Kevion K.Darmawan Rachael Moses Bicheng Yao Hongkang Wu Anders Barlow Marc-Antoine Sani Alastair J.Sloan Mohammed Akhter Hossain John D.Wade Yuning Hong Neil M.O’Brien-Simpson Wenyi Li | 2023 | Aggregate2023,4,4: | 0 |
