| 1 | T6热处理对触变锻造加低过热铸造制备的A356和A380铝合金的影响(英文)显示文摘研究T6热处理对触变锻造A356和A380铝合金的影响。采用低过热铸造(LSC)技术制备用于触变锻造的样品。为了获得等轴晶粒并防止枝晶生长,将样品在高于液相温度20°C时进行浇铸,将浇铸坯料再加热不同时间(20~80 min)后进行触变锻造,变形量为50%,再将触变锻造后的A356和A380铝合金样品进行T6热处理。用光学显微镜、能量弥散X射线谱仪、扫描电镜和布氏硬度仪对经触变锻造、固溶处理和时效处理后样品的显微组织和硬度变化进行检测。结果表明,T6热处理后合金的显微组织更均匀,并分别在A356和A380坯料中形成了新的析出相Mg_2Si和Al_2Cu。相应地,经过人工时效后,样品的硬度大幅度提高,A356铝合金的硬度达到HB 93,A380铝合金的硬度达到HB 120。 | Ridvan GECU Serhat ACAR Alptekin KISASOZ Kerem ALTUG GULER Ahmet KARAASLAN | 2018 | Transactions of Nonferrous Metals Society of China2018，28，3： | 2 |
| 2 | Ion imprinted cryogel-based supermacroporous traps for selective separation of cerium(Ⅲ) in real samples显示文摘This study demonstrates the preparation and characterization of a novel ion imprinted cryogel which exhibits high affinity and selectivity towards Ce(Ⅲ) ions in aqueous solutions and bastnasite ore samples.2-Hydroxyethyl methacrylate(HEMA) and N-methacryloylamido antipyrine(MAAP) were used as functional monomers for the preparation of Ce(Ⅲ) imprinted cryogel. The effects of various factors such as initial Ce(Ⅲ) concentration, flow rate, pH, interaction time and ionic strength on the Ce(Ⅲ) binding to the prepared ion imprinted cryogels were also studied. The binding equilibrium for Ce(Ⅲ) is obtained in30 min at the flow rate of 0.5 mL/min. The maximum binding capacity of the prepared ion imprinted cryogel towards Ce(Ⅲ) is obtained as 36.58 mg/g at optimum conditions. The selectivity of the prepared ion imprinted cryogel towards Ce(Ⅲ) in the presence of other possible interfering lanthanide ions such as La(Ⅲ) and Nd(Ⅲ) were also performed. The obtained results showed that the prepared ion imprinted cryogel exhibits high selectivity and sensitivity towards Ce(Ⅲ) ions. The limit of detection(LOD) was found as 50 μg/L. | Rüstem Kecili brahim Dolak Berrin Ziyadanogullari Arzu Ersoz Ridvan Say | 2018 | Journal of Rare Earths2018，36，8： | 2 |

| 8 | Hydatid cyst of the pancreas:Report of an undiagnosed case of pancreatic hydatid cyst and brief literature review显示文摘AIM: To overview the literature on pancreatic hydatid cyst(PHC) disease, a disease frequently misdiagnosed during preoperative radiologic investigation.METHODS: PubMed, Medline, Google Scholar, and Google databases were searched to identify articles related to PHC using the following keywords: hydatid cyst, hydatid disease, unusual location of hydatid cyst, hydatid cyst and pancreas, pancreatic hydatid cyst, and pancreatic echinococcosis. The search included let-ters to the editor, case reports, review articles, original articles, meeting presentations and abstracts that had been published between January 2010 and April 2014 without any restrictions on language, journal, or country. All articles identified and retrieved which contained adequate information on the study population(including patient age and sex) and disease and treatment related data(such as cyst size, cyst location, and clinical man-agement) were included in the study; articles with in-sufficient demographic and clinical data were excluded. In addition, we evaluated a case of a 48-year-old fe-male patient with PHC who was treated in our clinic.RESULTS: A total of 58 patients, including our one new case,(age range: 4 to 70 years, mean ± SD: 31.4 ± 15.9 years) were included in the analysis. Twenty-nine of the patients were female, and 29 were male. The information about cyst location was available from studies involving 54 patients and indicated the follow-ing distribution of locations: pancreatic head(n = 21), pancreatic tail(n = 18), pancreatic body and tail(n = 8), pancreatic body(n = 5), pancreatic head and body(n = 1), and pancreatic neck(n = 1). Extra-pancreatic locations of hydatid cysts were reported in the studies involving 44 of the patients. Among these, no other focus than pancreas was detected in 32 of the patients(isolated cases) while 12 of the patients had hydatid cysts in extra-pancreatic sites(liver: n = 6, liver + spleen + peritoneum: n = 2, kidney: n = 1, liver + kidney: n = 1, kidney + peritoneum: n = 1 and liver + lung: n = 1). Serological information was available in the studies involving 40 patients, and 21 of those pa-tients were serologically positive and 15 were serologi-cally negative; the remaining 4 patients underwent no serological testing. Information about pancreatic cyst size was available in the studies involving 42 patients; the smallest cyst diameter reported was 26 mm and the largest cyst diameter reported was 180 mm(mean ± SD: 71.3 ± 36.1 mm). Complications were avail-able in the studies of 16 patients and showed the fol-lowing distribution: cystobiliary fistula(n = 4), cysto-pancreatic fistula(n = 4), pancreatitis(n = 6), and portal hypertension(n = 2). Postoperative follow-up data were available in the studies involving 48 patients and postoperative recurrence data in the studies of 51 patients; no cases of recurrence occurred in any patient for an average follow-up duration of 22.5 ± 23.1(range: 2-120) mo. Only two cases were reported as having died on fourth(our new case) and fifteenth days respectively. CONCLUSION: PHC is a parasitic infestation that is rare but can cause serious pancreato-biliary complica-tions. Its preoperative diagnosis is challenging, as its radiologic findings are often mistaken for other cystic lesions of the pancreas. | Sami Akbulut Ridvan Yavuz Nilgun Sogutcu Bulent Kaya Sinan Hatipoglu Ayhan Senol Firat Demircan | 2014 | World Journal of Gastrointestinal Surgery2014，6，10： | 1 |

| 16 | 热处理条件对Al4Cu2Ni2Mg合金组织和磨损性能的影响(英文)显示文摘Al4Cu2Ni2Mg合金是一种可时效硬化合金。研究不同固溶和时效热处理工艺参数对Al4Cu2Ni2Mg合金显微组织、硬度和耐磨性能的影响。采用光学显微镜和扫描电镜对样品的显微组织进行表征。通过硬度测试和磨损试验研究热处理工艺对材料性能的影响。结果表明,合金经过8h时效后,硬度值从未经时效处理的HV1096.5增加到HV10151.1,继续延长时效时间会导致合金的硬度值下降。随着合金硬度的提高,其耐磨性能得到提升。综合实验结果表明,在540°C固溶处理8h,然后在190°C时效处理8h,为该合金的最优热处理条件。 | Erdem KARAKULAK Muzaffer ZEREN Ridvan YAMANOGLU | 2013 | Transactions of Nonferrous Metals Society of China2013，23，7： | 1 |
