Self-terminated oligomers with hyper branched architecture,also known as STOBA are combined with lithium ion battery cathode materials by two different ways:mechanical blending and surface coating.The comparative electrochemical analyses of the assembled coin cells demonstrates that for the mechanical blending combined materials no blocking effects are observed at high temperature condition.For the surface coating ones,STOBA has slightly impact on the cell performance at room temperature,but when the ambient temperature exceedes the cross- linking temperature,large area of crosslinking will occur on the surface of the electrode materials,which prevents the lithium ion from extracting and inserting.As a result,the battery totally loses charge-discharge capacity in the high rate discharge condition to ensure the safety when operating at high temperatures.

PET(Poly(Ethylene Terephthalate))- AlO ceramic composited separator is prepared with organic adhesives PDA,and inorganic silane coupling agent and colloidal silica.The obtained separator is characterized in different ways.Morphology characterization by SEM shows that porous separator is obtained and AlO is evenly distributed on it.The Gurley number of the separator is 8 s/100 cc.Thermal behaviour investigation and linear sweep voltammetry test show that the prepared separator has outstanding thermal performance and electrochemical stability.Half- cell assembled with the composited separator reveals an outstanding cycle performance and a good rate performance.Therefore,the separator may be a suitable and excellent candidate for application in power battery,especially the one with higher safety.

BACKGROUND： Hypoxia inducible factor-1 alpha （HIF-1 （x） and erythropoietin（EPO）, possessing neuroprotective effect in the cerebral ischemia, might play an important role in the formation of cerebral ischemic tolerance （IT）. OBJECTIVE：To observe the neuroprotective effect of cerebral ischemic preconditioning（IPC） of rats, and the expression and mechanism of HIF-1α and target gene erythropoietin in the brain tissue following the formation of cerebral IT. DESIGN ： A randomized and controlled observation SETTING： Department of Neurology, the Affiliated Hospital of Medical College, Qingdao University MATERIALS： Totally 84 enrolled adult healthy male Wistar rats of clean grade, weighing 250 to 300 g, were provided by the Animal Experimental Department, Tongji Medical College of Huazhong University of Science and Technology. Ready-to-use SABC reagent kit and rabbit anti-rat HIF-1α monoclonal antibody were purchased from Boshide Bioengineering Co.Ltd （Wuhan）; Rabbit anti-rat EPO monoclonal antibody was purchased from Santa Cruz Company （USA）. METHODS： This experiment was carried out in the Department of Anatomy, Medical College, Qingdao University during March 2005 to March 2006. ① The 84 rats were divided into 3 groups by a lot： IPC group （n=40）, sham-operation group （n=40） and control group （n=4）. In the IPC group, middle cerebral artery was occluded for 2 hours respectively on the 1^st, 3^rd, 7^th, 14^th and 21^st days of the reperfusion following 10-minute preischemia was made using a modified middle cerebral artery second suture method from Zea-Longa. The rats were sacrificed 22 hours after reperfusion in the end of middle cerebral artery occlusion （MCAO）. That was to say, after 10-minute preischemia, suture was exited to the extemal carotid artery and embedded subcutaneously. Middle cerebral artery was occluded again to form the second reperfusion at the set time point after reperfusion. Twenty-two hours later, rats were sacrificed; In the sham-operation group,the preischemia was substituted by sham-operation（only

With over a million cases detected each year,skin disease is a global public health problem that diminishes the quality of life due to its difficulty to eradicate,propensity for recurrence,and potential for post-treatment scarring.Photodynamic therapy(PDT)is a treatment with minimal invasiveness or scarring and few side effects,making it well tolerated by patients.However,this treatment requires further research and development to improve its effective clinical use.Here,a piezoelectric-driven microneedle(PDMN)platform that achieves high efficiency,safety,and non-invasiveness for enhanced PDT is proposed.This platform induces deep tissue cavitation,increasing the level of protoporphyrin IX and significantly enhancing drug penetration.A clinical trial involving 25 patients with skin disease was conducted to investigate the timeliness and efficacy of PDMN-assisted PDT(PDMN-PDT).Our findings suggested that PDMN-PDT boosted treatment effectiveness and reduced the required incubation time and drug concentration by 25%and 50%,respectively,without any anesthesia compared to traditional PDT.These findings suggest that PDMN-PDT is a safe and minimally invasive approach for skin disease treatment,which may improve the therapeutic efficacy of topical medications and enable translation for future clinical applications.

Animal taxonomy is a time-honoured discipline specializing in the classification of various species in the animal kingdom. Numerous zoologists have devoted their life-long careers to this subject and the voluminous literature left by them has become one of immortal legacies of the human pursuit of the unknown. Today, a monumental work in the field, "Fauna Sinica", is making its debut as one of basic research results on the

分析评价突出矿井采区通风系统的安全可靠性,对于优化突出矿井的通风系统、提高矿井的防灾、抗灾能力有重要现实意义。为了明确U型通风与Y型通风在突出矿井工作面应用中的优越性,本文分析了在U型通风和偏Y型“一进两回”通风情况下,工作面发生瓦斯突出时进风顺槽发生风流逆转的临界条件。以阳泉保安煤矿突出矿井的回采工作面实际通风条件为例,分析了偏Y型“一进两回”通风方式时,工作面推进对设置调节风窗位置的要求;并分析了两种通风方式下,工作面的推进距离与巷道发生突出引发风流逆转的临界瓦斯突出量关系。研究表明:在U型通风方式下,发生风流逆转临界突出瓦斯量随工作面剩余减短而降低,且降低速度逐渐加快。在Y型通风方式下,发生风流逆转临界突出瓦斯量随工作面剩余减短而呈近似线性降低。在工作面开采初期,偏Y型“一进两回”通风方式抵抗瓦斯突出引发风流逆转的能力远大于U型通风方式,但随着工作面推进,进风顺槽长度变短,这种优势越来越小。

为了解决阳泉地区强突碎软煤层的瓦斯治理问题,以上社煤矿为研究背景,采用定向长钻孔区域瓦斯治理技术,在15号煤层15205煤巷掘进工作面进行了现场试验。试验表明,与普通钻孔相比,长距离钻孔的瓦斯抽采浓度以及瓦斯抽采纯量均有了较大幅度的提高。在定向钻孔深度不断增大、分支钻孔数量日益增多时,长距离钻孔的瓦斯抽采浓度和瓦斯抽采纯量有所降低。抽采90 d后,钻孔平均瓦斯抽采浓度稳定在35%左右,平均瓦斯抽采纯量0.29 m3/min,平均百米钻孔瓦斯抽采量为0.0398 m3/min。
