| 1 | Experimental methods for determination of mechanical behaviors of materials at high temperatures via the split Hopkinson bars显示文摘Full understanding of the thermomechanical behaviors of materials at high strain rates and high temperatures are of great importance from not only scientific meaning but also practical value in engineering structure design and safety assessment.Great efforts have been made for abilities of operation the split Hopkinson bars,the most popular technique for experimental determination of mechanical behaviors of materials over the strain rates from 10^2 to 10^4 s^−1 over the past 70 years,at high temperatures since 1960s.A review of experiment work is presented in this paper to give an overview of the development of experimental techniques at high temperatures based on Hopkinson bar systems.The principles of the split Hopkinson bar requires the loading bars avoiding temperature gradient or keeping relatively low temperature when performing high temperature testing.Techniques such as performing temperature gradient corrections,rapid heating or using special designed automatically assembled systems were proposed by researchers to enable the operation of the split Hopkinson bars at temperature as high as possible.Moreover,to the application of high speed photographic technique for capturing the dynamic deformation process of the specimen in high temperature Hopkinson bar testing,some key issues of eliminating the strong thermal radiation induced lights oversaturation and de-blurring of images due to insufficient exposure at high temperature and high strain rate condition,as well as fabrication of high contrast speckle pattern for high temperature digital image correlation measurement were also proposed.The technique can now enable the split Hopkinson bar testing to be performed at high temperature up to 1873 K under the loading conditions of compression or tension with the in situ observation and full field measurement of deformation as well.The paper concludes with summaries of the most important achievements and highlighting of the prospects,trends and remaining challenges for future research. | Q.B.Dou K.R.Wu T.Suo C.Zhang X.Guo Y.Z.Guo W.G.Guo Y.L.Li | 2020 | Acta Mechanica Sinica2020，36，6： | 3 |
| 2 | 纯钛和镍包埋渗铝的热力学研究(英文)显示文摘分别在敞开和密闭系统中进行纯钛和纯镍的气相渗铝实验。渗铝实验在1100℃下进行3h,包埋粉末含10%Al、5%NH4Cl和85%Al2O3。在敞开条件下,渗铝后纯钛的表面会生成α(Al)固溶体,样品的质量损失达到32.37%。然而,在密闭条件下,纯钛样品的表面生成TiAl3层和α(Al)固溶体,没有质量损失。热力学分析表明,在敞开条件下对纯钛渗铝时,会生成钛的氯化物,导致其质量减少。而在密闭条件下,由于生成的氯化物会达到平衡状态而使生成反应停止。相反,无论是在敞开或密闭条件下,纯镍样品都可以进行表面渗铝,不会导致质量损失。在两种状态下,镍的表面都生成了AlNi和Ni3Al相。 | H.R.KARIMI ZARCHI M.SOLTANIEH M.R.ABOUTALEBI X.GUO | 2013 | 中国有色金属学会会刊:英文版2013，23，6： | 3 |

| 4 | 中国四川盆地页岩气注水压裂导致断层再活化并诱发MW4.7地震显示文摘本文对中国四川盆地最近观察到的注水诱发地震进行了及时和详细的研究,四川盆地页岩气水力压裂已经开始启动,计划在未来几年里被逐渐开采。包括传染型余震序列模型、震中重定位、13个大地震事件(MW>3.5)的震源机制以及库仑破裂应力数值计算的众多证据表明,在地下2.3~3km深度范围内水力压裂短期(每个井位数月)注水过程诱发了一系列最高矩震级达MW4.7的地震。反之,这些诱发地震的出现也支持了注水诱发断层再活化的假设。本文同时讨论了此地区注水压裂为什么会诱发如此大震级地震的地质原因。由于四川盆地中水力压裂作业正如火如荼,这也将有利于地球科学、天然气公司、管理部门和学术界共同探讨显著的注水诱发地震的地区因素,以确保页岩气注水压裂可以有效进行并安全实施。 | x.l.lei d.j.huang j.r.su g.m.jiang x.l.wang h.wang x.guo h.fu 唐茂云(译) 周红(校) | 2018 | 世界地震译丛2018，49，6： | 2 |
| 5 | 950~1100℃下纯钛NaF活化包埋渗铝的动力学研究(英文)显示文摘在温度为950、1025、1100℃,包埋层成分为10%Al+5%NaF+85%Al2O3(质量分数)的条件下,在纯钛上渗铝0-6 h。对样品上的渗铝层进行了表征。动力学研究表明,含铝气体通过包埋层的扩散过程是速率控制步骤。通过计算得到这个步骤的活化能为161.8 kJ/mol。通过包埋层中及样品表面气体的分压预测样品渗铝后的增重。在950℃的增重预测值与实验值吻合得很好,而在1025℃和1100℃的增重预测值比实验值高。 | H.R.KARIMI ZARCHI M.SOLTANIEH M.R.ABOUTALEBI X.GUO | 2014 | Transactions of Nonferrous Metals Society of China2014，24，6： | 2 |

| 11 | Connexin therapeutics:blocking connexin hemichannel pores is distinct from blocking pannexin channels or gap junctions显示文摘Compounds that block the function of connexin and pannexin protein channels have been suggested to be valuable therapeutics for a range of diseases.Some of these compounds are now in clinical trials,but for many of them,the literature is inconclusive about the molecular effect on the tissue,despite evidence of functional recovery.Blocking the different channel types has distinct physiological and pathological implications and this review describes current knowledge of connexin and pannexin protein channels,their function as channels and possible mechanisms of the channel block effect for the latest therapeutic compounds.We summarize the evidence implicating pannexins and connexins in disease,considering their homeostatic versus pathological roles,their contribution to excesive ATP release linked to disease onset and progression. | Monica L.Acosta Mohd N.Mat Nor Cindy X.Guo Odunayo O.Mugisho Frazer P.Coutinho Ilva D.Rupenthal Colin R.Green | 2021 | Neural Regeneration Research2021，16，3： | 1 |

| 17 | Potential development of non-synthetic food additives from orange processing by-products-a review显示文摘Citrus is the largest fruit crop worldwide.Meanwhile,oranges account for 60 per cent of the total,with their main application in juice production.During orange juice production,about 50 per cent of the fresh orange weight is transformed into juice,with the remaining 50 per cent comprised of residue(peel,pulp,seeds,orange leaves and whole orange fruits that do not reach the quality requirements).With the resulting tons of orange by-products,there has been an initiative to research possible ways to reutilize and revalorize citrus waste.Orange pomace,the by-product from juicing process,is currently used to extract the essential oils for fragrance and flavor,and a majority of the waste is used as cattle feed;however,these applications do not account for all of the waste or capture all of its potential value.Meanwhile,these by-products are put into landfills at the owner's expense,and contribute to global warming through carbon emissions.On the other hand,orange by-products still contain many useful nutraceutical components,such as dietary fiber and phytochemicals,which could be utilized for value-added ingredients and new product development.Some research approaches in this area include the production of organic fertilizers and biofuels,or the extraction of essential oils,pectins,and antioxidant compounds.There is little information in the literature and in the food industry in terms of utilizing the orange pomace directly or with some simple treatments.Orange pomace may be used for food product development as a'clean-laber,non-synthetic preservative,which rationalizes this review. | Erik S.Dassoff Jonathan X.Guo Yan Liu Selina C.Wang Yao Olive Li | 2021 | Food Quality and Safety2021，5，1： | 0 |
| 18 | Influences of nanotwin volume fraction on the ballistic performance of coarse-grained metals显示文摘Coarse-grained(CG) metals strengthened by nanotwinned(NT) regions possess high strength and good ductility. As such, they are very suitable for applications in bullet-proof targets. Here, a numerical model based on the conventional theory of strain gradient plasticity and the Johnson–Cook failure criterion is employed to study the influences of volume fraction of NT regions on their ballistic performance.The results show that in general a relatively small twin spacing(4–10 nm) and a moderate volume fraction(7%–20%) will lead to excellent limit velocity and that the influences of volume fraction on limit displacement change with the category of impact processes. | Q.D.Ouyang G.J.Weng A.K.Soh X.Guo | 2017 | Theoretical & Applied Mechanics Letters2017，7，5： | 0 |
