4Energy conversion characteristics of reciprocating piston quasi- isothermal compression systems using water sprays显示文摘Air compressors are vital and have numerous industrial applications. Approximately 8% of the annual operating electricity consumption in industrial countries is constituted by due to the use of air compressors. Because the poor heat transfer to the environment in the rapid compression process, the compression is non-isothermal, the efficiency of compressors is restricted. To improve their efficiency and achieve isothermal compression, this study proposes energy conversion reciprocating piston quasiisothermal compression using a water spray. First, a mathematical model of a reciprocating piston compressor with water sprays was established. Through experimental investigation and simulations, the mathematical model was validated. The energy conversion characteristics of the reciprocating piston compressor were then studied. To reduce compression power and enhance compression efficiency, it was first discovered that the critical parameters were the input pressure of the driving chamber, water spray mass, and compression volume ratio, which were then evaluated thoroughly. The higher the inlet pressure of the driving chamber, the faster the air compression velocity. Additionally, the compression efficiency was elevated as the water spray mass was gradually increased for a given compression volume ratio. When the compression volume ratio was increased from 2 to 3,the compression power increased from 172.7 J/stroke to 294.2 J/stroke and the compression efficiency was enhanced from 37.3%(adiabatic) to 80.6%. This research and its performance analysis can be referred to during the parameter design optimisation of reciprocating piston quasi-isothermal compression systems using water sprays.jia guanwei cai maolin xu weiqing shi yan 2018Science China(Technological Sciences)2018,61,2:6
5Therapeutic effect of electroacupuncture,massage,and blocking therapy on external humeral epicondylitis显示文摘OBJECTIVE:To compare two therapeutic methods:electroacupuncture + massage + blocking therapy,and blocking therapy alone in the treatment of external humeral epicondylitis.METHODS:Eighty-six patients were randomized into two groups with 43 in each. The treatment group received electroacupuncture + massage +blocking therapy, while the control group received blocking therapy only. A course of electroacupuncture treatment included therapy once a day for 10days. There were 10 treatments in a massage course and massage was given once a day, with a1-week interval given before the next course. A course of blocking treatment included therapy once a week, for twototaltreatments,andgenerallyno more than three times. The therapeutic effects were evaluated with the visual analog scale(VAS),grip strength index(GSI) score, and Mayo elbow performance score(MEPS) before treatment and at0, 6, 12, and 24 months after treatment to observe thetotaleffectiverate.RESULTS: In the treatment and control groups before treatment and at 0, 6, 12, and 24 months after treatment, the VAS scores were: 6.5±1.9 and 6.4±1.6; 4.6±1.3 and 4.6±1.7; 4.8±1.3 and 4.8±1.2; 4.6±1.2 and 6.6±1.6; and 6.5±1.6 and 6.5±1.3, respectively. The GSI scores were 63±8 and 63±8; 84±6and82±7;82±7and82±6;84±6and62±8;and64±6 and 64±7, respectively.The MEPS of both groups were65±7and66±8;85±6and84±7;84±5and84±7;80±7and66±6;and65±6and65±7,respectively.The total effective rates of the treatment and control groups at 0, 6, 12, and 24 months after treatment were 87.5% and 85.0%; 85.0% and 82.5%;80.0% and 12.5%; and 2.5% and 5.0%, respectively.Compared with the treatment group, the control group had greater joint function, better the rapeutic effect, and lower pain intensity(P<0.01), indicating a high recurrence rate in the 12th month after treatment.There were no differences inVAS, GSI, or MEPS at 0, 6, and 24 months after treatment(P>0.05)betweenthetwogroups.CONCLUSION: We found that both methods were effective for external humeral epicondylitis. After 6months of treatment,the effects were good in both groups. However, in the 12th month, the control group had a relatively severe relapse. After 24months, both groups relapsed. The effect of electroacupuncture, massage, and blocking therapy used in combination lasted longer, delaying the recurrence of the disease.Xinjian Li Kun Zhou Enming Zhang Zhen xiQi Weiqing Sun Liangfu Xu Jianfeng Xu Youzhi Cai Ronghui Wang 2014Journal of Traditional Chinese Medicine2014,34,3:6

10Tuning Atomically Dispersed Fe Sites in Metal–Organic Frameworks Boosts Peroxidase‑Like Activity for Sensitive Biosensing显示文摘Although nanozymes have been widely developed,accurate design of highly active sites at the atomic level to mimic the electronic and geometrical structure of enzymes and the exploration of underlying mechanisms still face significant challenges.Herein,two functional groups with opposite electron modulation abilities(nitro and amino)were introduced into the metal–organic frameworks(MIL-101(Fe))to tune the atomically dispersed metal sites and thus regulate the enzymelike activity.Notably,the functionalization of nitro can enhance the peroxidase(POD)-like activity of MIL-101(Fe),while the amino is poles apart.Theoretical calculations demonstrate that the introduction of nitro can not only regulate the geometry of adsorbed intermediates but also improve the electronic structure of metal active sites.Benefiting from both geometric and electronic effects,the nitro-functionalized MIL-101(Fe)with a low reaction energy barrier for the HO*formation exhibits a superior POD-like activity.As a concept of the application,a nitro-functionalized MIL-101(Fe)-based biosensor was elaborately applied for the sensitive detection of acetylcholinesterase activity in the range of 0.2–50 mU mL−1 with a limit of detection of 0.14 mU mL−1.Moreover,the detection of organophosphorus pesticides was also achieved.This work not only opens up new prospects for the rational design of highly active nanozymes at the atomic scale but also enhances the performance of nanozyme-based biosensors.Weiqing Xu Yikun Kang Lei Jiao Yu Wu Hongye Yan Jinli Li Wenling Gu Weiyu Song Chengzhou Zhu 2020Nano-Micro Letters2020,12,12:4
11Efficiency optimized fuel supply strategy of aircraft engine based on air-fuel ratio control显示文摘Accurate fuel injection control of aircraft engine can optimize the energy efficiency of UAV power system while meeting the propeller speed requirement. Traditional injection control method such as open-loop calibration causes instability of fuel supply which brings the risk of power loss of UAV. Considering that the closed-loop control of AFR can ensure a stable fuel feeding, this paper proposes an AFR control based fuel supply strategy in order to improve the efficiency of fuel-powered UAV while obtaining the required engine speed. According to the optimum fuel injection results, we implement fuzzy-PID method to control the set AFR in different situations. Through simulation and experiment studies, the results indicate that, to begin with, the calibrated mathematical model of the aircraft engine is effective. Next, this fuel supply strategy based on AFR control can normally realize the engine speed regulation, and the applied control algorithm can eliminate the overshoot of AFR throughout all the working progress. What is more,the fuel supply strategy can averagely shorten the response time of the engine speed by about two seconds. In addition, compared with the open-loop calibration, in this work the power efficiency is improved by 9% to 33%. Last but not the least, the endurance can be improved by 30 min with a normal engine speed. This paper can be a reference for the optimization of UAV aircraft engine.Yixuan WANG Yan SHI Maolin CAI Weiqing XU Qihui YU 2019Chinese Journal of Aeronautics2019,32,2:3
12Serum uric acid and risk of incident diabetes in middle-aged and elderly Chinese adults: prospective cohort study显示文摘The association between serum uric acid and the risk of incident diabetes in Chinese adults remains unknown.This study aimed to investigate this association in a community-dwelling population aged≥40 years in Shanghai,China.Oral glucose tole3rance test was conducted during baseline and follow-up visits.Relative risk regression was utilized to examine the associations between baseline gender-specific serum uric acid levels and incident diabetes risk.A total of 613(10.3%)incident diabetes cases were identified during the follow-up visit after 4.5 years.Fasting plasma glucose,postload glucose,and glycated hemoglobin A1c during the follow-up visit progressively increased across the sex-specific quartiles of serum uric acid(all Ps<0.05).The incidence rate of diabetes increased across the quartiles of serum uric acid(7.43%,8.77%,11.47%,and 13.43%).Multivariate adjusted regression analysis revealed that individuals in the highest quartile had 1.36-fold increased risk of diabetes compared with those in the lowest quartile of serum uric acid(odds ratio(95%confidence interval)=1.36(1.06−1.73)).Stratified analysis indicated that the association was only observed in women.Accordingly,serum uric acid was associated with the increased risk of incident diabetes among middle-aged and elderly Chinese women.Di Cheng Chunyan Hu Rui Du Hongyan Qi Lin Lin Xueyan Wu Lina Ma Kui Peng Mian Li Min Xu Yu Xu Yufang Bi Weiqing Wang Yuhong Chen Jieli Lu 2020Frontiers of Medicine2020,14,6:3
13MXene based mechanically and electrically enhanced film for triboelectric nanogenerator显示文摘The development of triboelectric nanogenerator(TENG)technology which can directly convert ambient mechanical energy into electric energy may affect areas from green energy harvesting to emerging wearing electronics.And,the material of triboelectric layer is critical to the mechanical robustness and electrical output characteristics of the TENGs.Herein,a MXene enhanced electret polytetrafluoroethylene(PTFE)film with a high mechanical property and surface charge density is developed.The MXene/PTFE composite film was synthesized by spraying and annealing treatment.With the doping of MXene,the crystallinity of composite film could be tuned,leading to an enhancement in the tensile property of 450%and reducing the wear volume about 80%in the friction test.Furthermore,the as-fabricated TENG with this composite film outputs 397 V of open-circuit voltage,21µA of short-circuit current,and 232 nC of transfer charge quantity,which are 4,6,and 6 times higher than that of the TENG made by pure PTFE film,respectively.Therefore,this work provides a creative strategy to simultaneously improve the mechanical property and electrical performance of the TENGs,which have great potential in improving device stability under a complex mechanical environment.Yuyu Gao Guoxu Liu Tianzhao Bu Yaoyao Liu Youchao Qi Yanting Xie Shaohang Xu Weili Deng Weiqing Yang Chi Zhang 2021Nano Research2021,14,12:2

15Self-sustained Oscillation Pulsed Air Blowing System for Energy Saving显示文摘Currently, many studies have been made for years on dimensions of pneumatic nozzle, which influence the flow characteristic of blowing system. For the purpose of outputting the same blowing force, the supply pressure could be reduced by decreasing the ratio of length to diameter of nozzle. The friction between high speed air and pipe wall would be reduced if the nozzle is designed to be converging shape comparing with straight shape. But the volume flow and pressure, discussed in these studies, do not describe energy loss of the blowing system directly. Pneumatic power is an innovative principle to estimate pneumatic system’s energy consumption directly. Based on the above principle, a pulse blowing method is put forward for saving energy. A flow experiment is carried out, in which the high speed air flows from the pulse blowing system and continuous blowing system respectively to a plate with grease on top. Supply pressure and the volume of air used for removing the grease are measured to calculate energy consumption. From the experiment result, the pulse blowing system performs to conserve energy comparing with the continuous blowing system. The frequency and duty ratio of pulse flow influence the blowing characteristic. The pulse blowing system performs to be the most efficient at the specified frequency and duty ratio. Then a pneumatic self-oscillated method based on air operated valve is put forward to generate pulse flow. A simulation is made about dynamic modeling the air operated valve and calculating the motion of the valve core and output pressure. The simulation result verifies the system to be able to generate pulse flow, and predicts the key parameters of the frequency and duty ratio measured by experiment well. Finally, on the basis of simplifying and solution of the pulse blowing system’s mathematic model, the relationship between system’s frequency duty ratio and the dimensions of components is simply described with four algebraic equations. The system could be designed with specified frequency and duty ratio according to the four equations. This study provides theoretical basis for designing energy-saving air blowing system.CAI Maolin XU Weiqing 2010Chinese Journal of Mechanical Engineering2010,23,3:2

19Efficacy and safety of degarelix in patients with prostate cancer:Results from a phase III study in China显示文摘Objective:To establish non-inferiority of gonadotropin-releasing hormone degarelix compared with goserelin in suppressing and maintaining castrate testosterone levels from Day 28 to Day 364 in Chinese patients with prostate cancer.Methods:This is an open-label,multi-centre study in which men aged18 years were randomised in a 1:1 ratio to once-a-month subcutaneous injection of either degarelix(240/80 mg)or goserelin(3.6 mg)for 12 months.The primary endpoint was difference in 1-year cumulative probability of suppressing testosterone to ≤0.5 ng/mL.Non-inferiority was to be established if the lower 95% confidence interval(CI)limit for difference in cumulative probability between the treatment arms was greater than -10%.Secondary endpoints included cumulative probability of prostate-specific-antigen-progression-free-survival(PSA-PFS).Safety was also assessed.Results:Baseline demographics and disease characteristics were similar between degarelix(n=142)and goserelin(n=141)treatment arms.The difference in cumulative probability of maintaining castrate levels from Day 28-364 was 3.6%(95%CI:-1.5%,8.7%),demonstrating non-inferiority of degarelix.The cumulative probability of PSA-PFS at Day 364 was higher for degarelix(82.3%,95%CI:74.7%,87.7%)versus goserelin(71.7%,95%CI:63.2%,78.5%,p=0.038).Adverse events(AEs)were similar between treatment arms,except for more injection site reactions with degarelix versus goserelin.Four(2.8%)and nine(6.4%)patients discontinued due to AEs in degarelix and goserelin groups,respectively.Yinghao Sun Liping Xie Tao Xu Jorn S.Jakobsen Weiqing Han Per S.Sorensen Xiaofeng Wang 2020Asian Journal of Urology2020,7,3:2
20Modulation of hot regions in waveguide-based evanescent-field-coupled localized surface plasmons for plasmon-enhanced spectroscopy显示文摘Coupling efficiency between the localized surface plasmons(LSPs) of metal nanoparticles(NPs) and incident light dominates the sensitivities of plasmon-based sensing spectroscopies and imaging techniques, e.g., surfaceenhanced Raman scattering(SERS) spectroscopy. Many endogenous features of metal NPs(e.g., size, shape,aggregation form, etc.) that have strong impacts on their LSPs have been discussed in detail in previous studies.Here, the polarization-tuned electromagnetic(EM) field that facilitates the LSP coupling is fully discussed.Numerical analyses on waveguide-based evanescent fields(WEFs) coupled with the LSPs of dispersed silver nanospheres and silver nano-hemispheres are presented and the applicability of the WEF-LSPs to plasmon-enhanced spectroscopy is discussed. Compared with LSPs under direct light excitation that only provide 3–4 times enhancement of the incidence field, the WEF-LSPs can amplify the electric field intensity about 30–90 times(equaling the enhancement factor of 10~6–10~8 in SERS intensity), which is comparable to the EM amplification of the SERS'hot spot' effect. Importantly, the strongest region of EM enhancement around silver nanospheres can be modulated from the gap region to the side surface simply by switching the incident polarization from TM to TE, which widely extends its sensing applications in surface analysis of monolayer of molecule and macromolecule detections. This technique provides us a unique way to achieve remarkable signal gains in many plasmon-enhanced spectroscopic systems in which LSPs are involved.HAILONG WANG YUYANG WANG YI WANG WEIQING XU SHUPING XU 2017Photonics Research2017,5,5:2
