Effect of Surface Pretreatment on Adhesive Properties of Aluminum Alloys

Journal of Materials Science & Technology 2008年第2期24卷 236-240页

作者： jinsheng ZHANG Xuhui zhao Yu ZUO Jinping XIONG Xiaofeng ZHANG School of Materials Science and Engineering Beijing University of Chemical Technology Beijing 100029 China

The lap-shear strength and durability of adhesive bonded AI alloy joints with different pretreatments were studied by the lap-shear test and wedge test. The results indicate that the maximum lap-shear strength and durability of the bonding joints pretreated by different processes are influenced by the grade of abrasive papers and can be obviously improved by phosphoric acid anodizing. Alkali etching can obviously improve the durability of bonding joints although it slightly influences the maximum lap-shear strength. The process which is composed of grit-finishing, acetone degreasing, alkali etching and phosphoric acid anodizing, provides a better adhesive bonding property of Al alloy.

引用

Neural Regeneration Research 2010年第11期5卷 853-858页

作者： Li Xiong Jian Yu Songjie Liao Shihui Xing Zhan zhao jinsheng Zeng Stroke Center and Department of Neurology First Affiliated Hospital Sun Yat-Sen University Guangzhou 510080 Guangdong ProvinceChina

BACKGROUND： Following ischemia, apoptosis is observed at the ipsilateral ventropostenor thalamic nucleus and substantia nigra, which are distant from, but connected to, the ischemic cerebral cortex, in animals with normotension. However, secondary brain damage in hypertension has not been clearly investigated. OBJECTIVE： The present study determined whether neuronal apoptosis is associated with neuronal loss in the ipsilateral ventroposterior thalamic nucleus and substantia nigra following cortical ischemia in adult hypertensive rats. Results should provide options for determining a time window for anti-apoptotic therapy. DESIGN, TIME AND SETTING： All experimental procedures in this randomized, controlled trial were conducted at the Neurological Laboratory of the First Affiliated Hospital of Sun Yat-sen University of China between October 2006 and July 2008. MATERIALS： Monoclonal primary antibodies specific to mouse anti-rat microtubule-associated protein 2 and glial fibrillary acidic protein were respectively purchased from Sigma Chemical, USA and BD Pharmingen, USA. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end-labeling （TUNEL） detection kits were purchased from Roche Applied Science, Switzerland and Upstate, USA, respectively. METHODS： A total of 64 male, Sprague Dawiey rats, aged 60-90 days, were equally and randomly divided into middle cerebral artery occlusion and sham surgery groups. Renovascular hypertension was established in both groups by renal artery occlusion. Right distal middle cerebral artery occlusion was performed by electrocoagulation in the middle cerebral artery occlusion group. MAIN OUTCOME MEASURES： Microtubule-associated protein 2 and glial fibrillary acidic protein were detected by immunohistochemistry, and apoptotic cells were observed by TUNEL assay. The stainings were separately detected in the ipsilateral ventroposterior thalamic nucleus and substantia nigra. RESULTS： During the 4 weeks followin

Chinese Science Bulletin 2011年第31期56卷 3242-3246页

作者： MU Xue WU ChuanLiu LAI JinPing CHEN JianBin ZHENG jinsheng LI Chong zhao YiBing Department of Chemistry and the Key Laboratory of Analytical Sciences of Xiamen University College of Chemistry and Chemical EngineeringXiamen University Xiamen 361005 China

A general and facile approach was developed for the synthesis of almost monodisperse fluorescent silica nanoparticles (NPs) doped with inert dyes, which are organic fluorophores that are strongly fluorescent but are hydrophobic or lack a covalent binding group. The prepared NPs were mesoporous and the dye molecules were encapsulated in the pores via hydrophobic interaction with the CTAB template. The NPs were stable and highly fluorescent in aqueous solution, and have potential applications in bioanalysis and fluorescence encoding.

Gd_(2) O_(3) nanoparticles modified g-C_(3) N_(4) photocatalytic composites were synthesized by a simple one-step hydrothermal *** structure,morphology,optical properties of the prepared photocatalyst were characterized by X-ray diffraction(XRD),field emission scanning electron microscopy(FESEM),field emission transmission electron microscopy(FETEM) and X-ray photoelectron spectroscopy(XPS).The result demonstrates that gadolinium is mainly dispersed on the surface of g-C_(3) N_(4) in the form of Gd_(2) O_(3),and does not destroy the lattice structure of g-C_(3) N_(4).Besides,the gadolinium can cause the red shift of the absorption edge of light,narrow the band gap,and increase the separation efficiency of the photogenerated electron and hole of g-C_(3) N_(4).Especially,the specific surface area of g-C_(3) N_(4) can be significantly ***,g-C_(3) N_(4)/Gd-0.05 displays the highest photodegradation performance when it is used for degradation of methyl orange(MO),methylene blue(MB) and Rhodamine B(RhB).The photodegradation rate of g-C_(3) N_(4)/Gd-0.05 composites is 72.4% for MO,95.5% for RhB,100% for MB after120 min under visible light(λ> 420 nm) *** band gap promotes the separation of photogenerated electron and hole,which enhances the photocatalytic activity of g-C_(3) N_(4).It is noted that g-C_(3) N_(4)/Gd-0.05 exhibits excellent photocatalytic stability by the photocurrent and the cyclic photodegradation of MO.

电离层延迟是制约单频接收机定位精度的重要误差源之一.为提高单频接收机的实时电离层改正精度,需要实时电离层数据.以中国科学院空天信息创新研究院提供的实时电离层数据为例,对比分析不同太阳活动期实时电离层数据及预报电离层数据与IGS最终电离层数据之间的差值以及不同太阳活动期、不同纬度测站的电离层数据对电离层延迟进行改正后得到的定位精度.结果表明:在低太阳活动期和高太阳活动期,实时电离层数据无法很好地反映大部分海洋上空的电离层变化特性;对不同太阳活动期,实时电离层数据在高纬度测站的定位精度优于预报数据和广播模型,在中纬度测站的定位精度略低于预报数据而与广播模型定位精度相当,在低纬度测站的定位精度略优于预报数据和广播模型.

为了解决双向DC-DC变换器输入、输出电压范围过窄的问题,该文提出一种高增益对称双向LCLC谐振变换器。提出的谐振变换器不是利用变压器的励磁电感参与谐振,而是在变压器的一次侧并联一个LC支路代替变压器励磁电感的作用,使得变换器在电感比较大的情况下仍有较高的增益,兼顾了LLC型谐振变换器在谐振点的高效率和宽的增益范围,且能保证一次侧和二次侧的软开关特性,实现谐振变换器的对称双向运行。该文基于基波分析法建立基波等效模型,推导出变换器的增益公式,分析谐振参数对直流增益特性的影响。最后搭建一台100~200V/24~48V、500W的实验样机,实验结果验证了理论分析的正确性和所提出拓扑结构的可行性及有效性,样机的最大效率达到96.3%。

Electrochemical evaluation of the inhibitory effects of acetic acid on Saccharomyces cerevisiae

High Technology Letters 2006年第2期12卷 203-206页

作者：袁振宏 zhao jinsheng Yan Yongjie Yang Zhengyu Department of Chemical Engineering for Energy Resources East China University of Science ＆ Technology Shanghai 200237 P.R.China Technical Institute of Physics and Chemistry Chinese Academy of Sciences Beijing 100101 P.R. China

A mediated electrochemical method was proposed for toxic evaluation of acetic acid on S. cerevisiae AS. 380, and menadione/ferricyanide was chosen as the mediator system. The variance in electrochemical response in the absence and presence of increasing concentrations of acetic acid were used to indicate the inhibitory effects of weak acid on the yeast. The inhibitory effects of acetic acid on glucose consumption during menadione mediated reduction of ferricyanide were also measured for comparison purpose. The relative limiting current and the glucose consumption were reduced by 64.5% and 61%, respectively, in the presence of 4g/L acetic acid at pH 4.0. The results showed that the electrochemical method can provide us with an appropriate and convenient tool for cytotoxic evaluation.
