Abstract: 摘要 二次锂硫电池被视为最具有发展潜力的下一代高能量密度二次电池之一. 但由于正极硫的电导率低(5×10-30 S·cm-1),且在放电过程中产生的中间体多硫化物易溶于有机电解液,致使锂硫电池活性物质利用率降低,溶解后的多硫化物还会迁移到负极,被还原成不溶物Li2S2/Li2S而沉积于负极锂,使电极结构遭受破坏,造成电池容量大幅衰减,循环性能差,从而限制了进一步的开发应用. 研究表明,以碳作为导电骨架的硫碳复合正极材料能在不同程度上解决上述问题,从而有效提高了锂硫电池的放电容量和循环性能. 本文综述了近年来国内外报道的各种锂硫电池正极材料的研究进展,结合作者课题组的研究,重点探讨了硫碳复合正极材料,并对其今后的发展趋势进行了展望

Abstract: 摘要 由于高安全、高功率和超长循环寿命等优点,钛酸锂负极材料近年来得到了广泛关注,基于钛酸锂负极的高性能超级电池电容器和锂离子电池也成为近年来的研究热点. 本文采用化学氧化法制备了有机物正极材料聚三苯胺,并通过经典的电化学测试方法研究了其储能机理及相应的电极动力学过程. 研究结果表明,该有机物正极的储能机制主要是基于阴离子的吸脱附反应,并表现出85 mA·g-1的可逆容量,且其动力学过程不受扩散控制,属于典型的赝电容行为. 将该正极与钛酸锂负极结合构成了新型的电池电容体系,并对其电化学性能进行了研究,结果表明该体系具有高功率特性,且能量密度高于传统的混合型超级电容器. 此外,本文还对该有机物正极的不足和实际应用中所面临的挑战做了初步分析

Abstract: Lupus nephritis (LN) is a major complication of systemic lupus erythematosus and is associated with high rates of morbidity and mortality. Although clinical signs of renal involvement appear in only 50–80% of patients, the disease involves the kidney in almost all patients from whom sufficient tissue can be obtained for analysis [1]. Both renal and extrarenal events are involved in the pathogenesis of the disease. Bacterial and viral infections may serve as environmental triggers for the development or exacerbation of systemic lupus erythematosus in genetically predisposed individuals. Lupus patients are more prone to develop common (pneumonia, urinary tract infection, cellulitis, and sepsis), chronic (tuberculosis), and opportunistic infections, possibly because of genetic and immunologic defects [2]. Experimentally, when exposed to bacterial lipopolysaccharide (LPS), NZB/W mice promptly developed an accelerated diffuse proliferative nephritis [3,4], clinically and pathologically mimicking the transformation of renal lesion types from low grade to high grade in LN patients. Although increased immune complex deposition and proliferation of intrinsic cells in the affected glomeruli were observed in the NZB/W mice that received LPS administration [3], the actual mechanisms underlying the accelerated form of the LN model remain largely unclear. Recent studies suggest that mesangial cells (MCs) play a critical role in LN and regulate inflammatory responses inside the compromised glomeruli [5-9]. It is unknown whether MCs of the lupus-prone mice are more sensitive to an infectious agent than MCs of their normal control. This prompted us to evaluate chemokine production by NZB/W MCs both in the baseline (normal culture, 20% fetal bovine serum (FBS)) condition and when exposed to bacterial LPS to simulate (under 2% FBS), respectively, the normal physiological status and superimposed infection.Recent studies have demonstrated that expression of LPS-induced monocyte chemoatt

Abstract: In order to study the attenuation of shock waves induced by a high-power pulsed laser in magnesium alloy, an AZ31B magnesium alloy sample is processed with an Nd:Glass laser with a wavelength of 1054 nm and pulse width of 23 ns, and the relative pressures of the shock waves are measured on time by a polyvinglidene fluoride (PVDF) gauge with a short rise time and a wide linear response range, combined together with an oscilloscope. The law of attenuation of laser shock wave is obtained by measuring the intensity pressures on the rear surface of the target for different thicknesses through which the shock waves pass each time. The experimental results show that the average velocity of the shock wave attenuation in magnesium alloy is 5.83×103 m/s with using a laser pulsed energy of 5 J is in good agreement with the propagation velocity of stress longitudinal wave; the law of the shock wave attenuation is exponential. The experimental result can be very useful for the laser shock processing on magnesium alloy.

Thermogravimetric analysis of fuel film evaporation
Zongjie Hu,Liguang Li,Shui Yu
Chinese Science Bulletin , 2006, DOI: 10.1007/s11434-006-2091-3
Abstract: Thermogravimetric analysis (TGA) was compared with the petrochemical distillation measurement method to better understand the characteristics of fuel film evaporation at different wall temperatures. The film evaporation characteristics of 90# gasoline, 93# gasoline and 0# diesel with different initial thicknesses were investigated at different environmental fluxes and heating rates. The influences of heating rate, film thickness and environmental flux on fuel film evaporation for these fuels were found. The results showed that the environmental conditions in TGA were similar to those for fuel films in the internal combustion engines, so data from TGA were suitable for the analysis of fuel film evaporation. TGA could simulate the key influencing factors for fuel film evaporation and could investigate the basic quantificational effect of heating rate and film thickness. To get a rapid and sufficient fuel film evaporation, sufficiently high wall temperature is necessary. Evaporation time decreases at a high heating rate and thin film thickness, and intense gas flow is important to promoting fuel film evaporation. Data from TGA at a heating rate of 100°C/min are fit to analyze the diesel film evaporation during cold-start and warming-up. Due to the tense molecular interactions, the evaporation sequence could not be strictly divided according to the boiling points of each component for multicomponent dissolved mixture during the quick evaporation process, and the heavier components could vaporize before reaching their boiling points. The 0# diesel film would fully evaporate when the wall temperature is beyond 250°C.

Abstract: BACKGROUND: Alzheimer disease (AD) is a chronic neurodegenerative disease that is characterized by its gradual progression. At present, the cause and mechanism of AD are yet unclear, and there is no effective therapy for treating it. With development of global aging, the prevalence rate of AD is increasing. The life quality of elderly people is affected severely by AD that is ultimately life-threatening. Recently, study on treating AD with traditional Chinese medicine (TCM) has deepened.OBJECTIVE: To explore the therapeutic effects of a syndrome differentiation-based TCM regime in treating patients with mild to moderate AD for improving cognition, and to evaluate the changes in brain function of AD patients observed by resting-state functional magnetic resonance imaging (fMRI) technique.DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: Adopting the internationally recognized criteria developed by National Institute of Neurological and Communicative Diseases and Stroke/Alzheimer’s Disease and Related Disorders Association, the clinical trial was conducted on 131 patients with mild to moderate AD from 5 communities and 7 social welfare institutions. Participants were accepted after informed consent was received, and laboratory tests and a head imaging study were conducted. The patients were randomly divided into Chinese medicine group (CMG) (66 cases) or Western medicine group (WMG) (65 cases). Patients in the CMG were treated monthly with Chinese medicine according to syndrome differentiation. Patients in the WMG were treated with donepezil at a dose of 5 mg once daily. The therapeutic course lasted 48 weeks.MAIN OUTCOME MEASURES: The scores of Mini-Mental State Examination (MMSE), Fuld Object-Memory Evaluation (FOM), Block Design (BD) and Digit Span (DS) were used to evaluate the cognitive function; resting-state fMRI was used for observing brain function. The questionnaires and fMRI were performed before and after treatments.RESULTS: The cognitive functions of the patients in the CMG and WMG were improved after treatment. MMSE score was improved significantly in both groups (P<0.05 or P<0.001). After 48 weeks of treatment, 70.91% patients in the CMG had an improved MMSE score and 20% got worse, however, 55.77% patients in the WMG were improved in MMSE score and 34.62% got worse. Scores of FOM denominator and BD increased significantly in both groups; scores of FOM numerator and DS were also increased in the CMG (P<0.05 or P<0.01). The results of fMRI suggested that both Chinese medicine and donepezil treatment improved the connectivity between posterior
