| 1 | 不同热处理态2024铝合金的腐蚀行为(英文)显示文摘分别在3.5%NaCl溶液、3.5%NaCl+1.0%H2O2溶液和pH=12的3.5%NaCl溶液中进行动电位极化实验,研究2024 Al-Cu-Mg合金在不同热处理状态下的腐蚀行为。极化曲线表明,随着合金时效时间的延长,合金的腐蚀电位向负方向移动;向NaCl溶液中添加H2O2会使腐蚀电位正移;在pH=12的3.5%NaCl溶液中的极化曲线表现出明显的钝化现象。腐蚀试样表面表现为常见的腐蚀特征,但也有扩大的点蚀、晶间腐蚀现象出现。循环动电位极化曲线显示有宽的循环极化滞后环,不同的腐蚀模式表明合金的点蚀生长对合金的热处理状态敏感。通过显微组织分析,探讨了不同热处理状态下合金在不同NaCl溶液中的腐蚀机理。 | K.S.GHOSH Md.HILAL Sagnik BOSE | 2013 | Transactions of Nonferrous Metals Society of China2013，23，11： | 10 |
| 2 | 热改性废茶叶吸附刚果红性能的研究显示文摘采用热改性废茶叶吸附刚果红染料,考察了pH、吸附剂投加量、染料液浓度和温度对热改性废茶叶吸附染料性能的影响。采用SEM和BET研究了热改性茶叶的基本物理化学特性,最后采用伪一阶动力学模型和伪二阶动力学模型拟合了改性废茶叶对刚果红染料的吸附动力学过程,并对其吸附热力学进行分析。结果表明,热改性废茶叶表面出现了形状各异的小孔,其比表面积、总孔容和平均孔径比改性前增加较多;当溶液质量浓度为50 mg/L、pH为4、吸附剂投加量为0.4 g/L、温度为35℃时,染料的吸附率达到最佳,为98.4%,吸附量为123 mg/g;热改性废茶叶对刚果红吸附动力学符合伪二阶动力学模型,吸附过程是由物理吸附和化学吸附共同决定的。热力学分析表明,吸附过程是自发进行的吸热过程。 | 王泽怿 赵斌 沈伯雄 Sagnik Chakraborty 高兰君 | 2017 | 工业水处理2017，37，4： | 9 |
| 3 | 热改性废茶叶对茜素红的吸附性能显示文摘研究了热改性废茶叶吸附印染废水中茜素红的特性,考察了作用时间、温度、茜素红初始浓度和吸附剂用量等对热改性废茶叶吸附废水中茜素红的影响。结果表明:废茶叶经过改性,表面孔结构发生变化,微孔和中孔的数量相比改性前有很大提高,改性废茶叶对茜素红的去除率可达98.22%,最大吸附量达到255.755 mg/g;吸附平衡较好地符合Langmuir模型,相关系数达90%以上;动力学计算结果表明,改性废茶叶吸附茜素红符合伪二级方程,表明改性废茶叶对茜素红的吸附以化学吸附为主。 | 高兰君 沈伯雄 Sagnik Chakraborty 王泽怿 | 2017 | 印染2017，43，12： | 3 |

| 20 | Coronavirus Disease-2019(COVID-19)and the Liver显示文摘Within a year of its emergence,coronavirus disease-2019(COVID-19)has evolved into a pandemic.What has emerged during the past 1 year is that,apart from its potentially fatal respiratory presentation from which the severe acute respiratory syndrome-coronavirus-2(SARS-CoV-2)derives its name,it presents with a myriad of gastrointestinal(GI)and liver manifestations.Expression of the angiotensinconverting enzyme-2(ACE-2)receptor throughout the GI tract and liver,which is the receptor for the SARS-CoV-2,may be responsible for the GI and liver manifestations.Besides acting directly via the ACE-2 receptor,the virus triggers a potent immune response,which might have a role in pathogenesis.The virus leads to derangement in liver function tests in close to 50%of the patients.The impact of these derangements in patients with a normal underlying liver seems to be innocuous.Severe clinical presentations include acute decompensation and acute-on-chronic liver failure in a patient with chronic liver disease,leading to high mortality.Evolving data suggests that,contrary to intuition,liver transplant recipients and patients with autoimmune liver disease on immunosuppression do not have increased mortality.The exact mechanism underlying why immunosuppressed patients fare well as compared to other patients remains to be deciphered.With newer variants of COVID-19,which can spread faster than the original strain,the data on hepatic manifestations needs to be updated to keep a step ahead of the virus. | Anshuman Elhence Manas Vaishnav Sagnik Biswas Ashish Chauhan Abhinav Anand Shalimar | 2021 | Journal of Clinical and Translational Hepatology2021，9，2： | 0 |
