| 1 | Adjustable character of microwave attenuation in BaTiO_3 electrorheological fluids显示文摘The behavior of microwave attenuation in BaTiO3 electrorheological fluids is studied when considering microwave propagation in the directions perpendicular and parallel to the particle chains, respectively. In the former case, the microwave attenuation increases with field strength when the particle concentration is low, and the increase of the particle concentration can also increase the microwave attenuation. However, when the particle concentration exceeds a critical value, the attenuation will first increase then decrease with field strength. At the same time, the higher the field strength, the greater the change of microwave attenuation. Moreover, there is a saturation field strength. When the field strength is lower than the saturated one, the change of microwave attenuation is fast. On the other hand, in the case of microwave propagation parallel to the particle chains, the microwave attenuation increases with the field strength monotonously. In addition, the variation of microwave attenuation with the field strength shows relaxation effect. The adjustable character of microwave attenuation in BaTiO3 ER fluids can be attributed to the dielectric changes resulting from the field-induced-structural transformation and the polarization of BaTiO3. | FAN Jijun, ZHAO Xiaopeng , HUANG Min, GUAN Litao and WEN Lishi(1.

| 2 | Analysis on the process of ZAO films by DC magnetron reactive sputtering显示文摘The ZAO (ZnO:Al) thin films were prepared by DC reactive magnetron sputtering technique. The relationship between the process parameters and the organizational structure,optical and electrical properties was studied. Through optimizing the process parameters,an optimal preparation parameter can be obtained. Using the optimal parameters to prepare the ZAO thin films,the resistivity of the ZAO film is as low as 4.5×10-4 Ω·cm and the average transmissivity in the visible region is around 80%,the optical and electrical properties meet the application requirements. | LU Feng XU ChengHai WEN LiShi | 2011 | Science China(Technological Sciences)2011，54，1： | 4 |

| 4 | Properties of Reactive Magnetron Sputtered ITO Films without in-situ Substrate Heating and Post-deposition Annealing显示文摘Indium tin oxide (ITO) films were prepared on polyester, Si and glass substrate with relatively high deposition rate of above 0.9 nm/s by DC reactive magnetron sputtering technique at the sputtering pressure of 0.06 Pa system, respectively. The dependence of resistivity on deposition parameters, such as deposition rate, target-to-substrate distance (TSD), oxygen flow rate and sputtering time (thickness), has been investigated, together with the structural and the optical properties. It was revealed that all ITO films exhibited lattice expansion. The resistivity of ITO thin films shows significant substrate effect: much lower resistivity and broader process window have been reproducibly achieved for the deposition of ITO films onto polyester rather than those prepared on both Si and glass substrates. The films with resistivity of as low as 4.23 ?10-4 Ω.cm and average transmittance of -78% at wavelength of 400-700 nm have been achieved for the films on polyester at room temperature. | Meng CHEN, Xuedong BAI, Jun GONG, Chao SUN, Rongfang HUANG and Lishi WEN (Institute of Metal Research, the Chinese Academy of Sciences, Shenyang 110015, China) | 2000 | Journal of Materials Science & Technology2000，16，3： | 4 |
| 5 | A SPH simulation on large-amplitude sloshing for fluids in a two-dimensional tank显示文摘Smoothed particle hydrodynamics(SPH) is a mesh-free adaptive Lagrangian particle method with attractive features for dealing with the free surface flow.This paper applies the SPH method to simulate the large-amplitude lateral sloshing both with and without a floating body,and the vertical parametrically-excited sloshing in a two-dimensional tank.The numerical results show that the SPH approach has an obvious advantage over conventional mesh-based methods in handling nonlinear sloshing problems such as violent fluid-solid interaction,and flow separation and wave-breaking on the free fluid surface.The SPH method provides a new alternative and an effective way to solve these special strong nonlinear sloshing problems. | Wang Lishi Wang Zhuang Li Yuchun | 2013 | Earthquake Engineering and Engineering Vibration2013，12，1： | 3 |
| 6 | Development of FGF-2-loaded electrospun waterborne polyurethane fibrous membranes for bone regeneration显示文摘Guided bone regeneration(G BR)membrane has been used to improve functional outcomes for periodontal regener ation.However,few studies have focused on the biomimetic membrane mim-icking the vascularization of the periodontal membrane.This study aimed to fabricate waterborne polyurethane(WPU)fibrous membranes loaJed fibroblast growth factor-2(FGF-2)via emulsion electrospinning,which can promote regeneration of periodontal tissue via the vascularization of the biomimetic GBR membrane.A biodegradable WPU was synthesized by using lysine and dime-thylpropionic acid as chain extenders according to the rule of green chemical synthesis technology.The WPU fibers with FGF-2 was fabricated via emulsion electrospinning.The results confirmed that controlled properties of the fibrous membrane had been achieved with controlled degradation,suitable mech anical properties and sustained release of the factor.The immunohistochemical expression of angiogenic-related factors was positive,meaning that FGF-2 loaded in fibers can sig-nificantly promote cell vasculariz ation.The fiber scaffold loaded FGF-2 has the potential to be used as a functional GBR membrane to promote the formation of extraosseous blood vessels during periodontal repairing. | Chi Zhang Jianxiong Wang Yujie Xie Li Wang Lishi Yang Jihua Yu Akira Miyamoto Fuhua Sun | 2021 | Regenerative Biomaterials2021，8，1： | 3 |

| 8 | Ultrasensitive electrochemical determination of metronidazole based on polydopamine/carboxylic multi-walled carbon nanotubes nanocomposites modified GCE显示文摘An ultrasensitive electrochemical sensor based on polydopamine/carboxylic multi-walled carbon nanotubes(MWCNTs à COOH) nanocomposites modified glassy carbon electrode(GCE) was presented in this work, which has been developed for highly selective and highly sensitive determination of an antimicrobial drug, metronidazole. The preparation of polydopamine/MWCNTs–COOH nanocomposites/GCE sensor is simple and possesses high reproducible, where polydopamine can be coated on the surface of MWCNTs–COOH via a simple electropolymerization process. Under optimized conditions, the proposed sensor showed ultrasensitive determination for metronidazole with a wide linear detection range from5 to 5000 mmol/dm^3 and a low detection limit of 0.25 mmol/dm^3(S/N=3). Moreover, the proposed sensor has been successfully applied for the quantitative determination of metronidazole in real drug samples. This work may provide a novel and effective analytical platform for determination of metronidazole in application of real pharmaceutical and biological samples analysis. | Satar Tursynbolat Yrysgul Bakytkarim Jianzhi Huang Lishi Wang | 2018 | Journal of Pharmaceutical Analysis2018，8，2： | 3 |
| 9 | Absorption and biotransformation of four compounds in the Guizhi decoction in the gastrointestinal tracts of rats显示文摘OBJECTIVE:To study the absorption and biotransformation of liquiritin,cinnamic acid,paeoniflorin,and glycyrrhizic acid in the Guizhi decoction (GZD) in the gastrointestinal tracts of rats.METHODS:A simple and reliable high-performance liquid chromatography method was established and validated for the analysis of the four components of GZD simultaneously in the gastrointestinal tracts of rats.Rats were randomly divided into in situ gastrointestinal loop model,in vitro anaerobic culture model,and blank control groups.All rats were fasted for 12 h and anesthetized using 20% urethane.Subsequently,the abdominal cavity of each rat was opened,and the stomach,duodenum,jejunum,ileum,cecum,and colon were ligated.For the in situ gastrointestinal loop model group,2.5 mL of GZD (1.0 g crude drug/mL,37 ℃)were injected into the gastrointestinal tract.The abdominal incision was covered with warm,wet cotton,and animals were maintained at 25 ℃.Then,we collected the gastrointestinal tract content after 1.5 h.For the in vitro anaerobic culture model group,the gastrointestinal tract contents of rats were collected and then cultured in 2.5 mL of GZD in an anaerobic environment at 25 ℃ for 24 h.For the blank control group,rats received the same volume of a normal saline solution instead of GZD.High performance liquid chromatography was used to detect the liquiritin,cinnamic acid,paeoniflorin,and glycyrrhizic acid concentrations in each group and calculate the absorption and biotransformation rates of each ingredient.RESULTS:Cinnamic acid (low polarity) was more easily absorbed by each gastrointestinal part than the higher-polarity glycosides.However,the absorption rate in the cecum was higher than that in other parts.The four compounds,cinnamic acid,liquiritin,paeoniflorin,and glycyrrhizic acid,were transformed completely within 24 h in the cecum and colon,whereas they were hardly transformed in the stomach,excluding glycyrrhizic acid.In addition,all ingredients had higher biotransformation rates in the distal small intestine than that in the proximal small intestine.CONCLUSION:Although a portion of the glycosides in GZD was directly absorbed as the prototype forms in the gastrointestinal tract,they were primarily metabolized and transformed into their corresponding metabolites by intestinal flora near the distal small intestine before their absorption. | Gao Huan Zhang Lishi Song Jiannan Bai Dong | 2019 | Journal of Traditional Chinese Medicine2019，39，3： | 3 |
